[0126] FIG. 41 - Challenges associated with the development of conventional bifunctional molecules. Similar PTM-inducing/removing chimeras are being developed by various labs and involve screening [e.g., using mass spectrometry (ABPP), DNA-encoded library or small molecule screening) to identify non-inhibitory binders of various PTM-inducing/removing enzymes. These approaches have several challenges: 1) Involves de novo ligand discovery and optimization, which is32yridinee and time intensive 2) Identifying non-inhibitory pockets on enzymes is non-trivial and such pockets may be non-existent for certain enzymes 3) Discovered ligands will have unknown pharmacology (e g., specificity, off-targets, PK/PD) 4) Mass spec methods primarily use small molecule fragments that have poor binding affinity. Applicants repurpose existing high- quality inhibitors of PTM-inducing/removing enzymes. Such inhibitors are abundantly available for nearly all PTM-inducing/removing enzymes.

[0128] FIG. 43A-43C - PHICS can be developed using kinase inhibitors. A PHICS can be designed from a kinase inhibitor in which a nucleophile (e.g., cysteine) near the inhibitor-binding pocket can initiate an addition-elimination reactivity resulting in appending the target-protein binder to the kinase while releasing the inhibitor from the kinase’s active site (43 A). The kinase binder in such cysteine-triggered PHICS can be derived from abundantly available acrylamide- based inhibitors, where the amide nitrogen is often aryl-amine (43 C) or less frequently aliphatic amine (43B). Using these BTK inhibitor scaffolds, Applicants synthesized BRD4 PHICS with aryl amine scaffold (43C) or aliphatic amine scaffold (43B), wherein the inhibitor is connected to BRD4 binder JQ1 via cleavable methacrylamide linker. Applicants also synthesized Iphics (inactive controls using I-JQ1 that does not bind to BRD4) and tested in PHICS can rewire BTK’s specificity and induce phosphorylation ofBRD4. Indeed, Applicants observed much higher BRD4 phosphorylation in the presence PHICS than with iPHICS. Applicants also observed significantly higher levels of co-immunoprecipitated BTK-FLAG and higher levels of BRD4 phosphorylation in presence of PHICS than that of iPHICS. Beyond BTK, Applicants have successfully developed recruiting ligands for EGFR, FGFR (pan), FGFR4, ITK, JAK3, and CDK2.
[0129] FIG. 44A-44C - Data showing group transfer reactivity in cells. Applicants performed target engagement studies using compounds that have alkyne handle in place of JQ1 (41 A) and confirmed that the scaffolds covalently engaged BTK in cells (41B). Briefly, HEK293T cells transiently expressing BTK were treated with alkyne-containing compounds for 4h. After washing with PBS and lysis, cell lysates were introduced to Cu-catalyzed click reaction with sulfo-Cy5.5 azide and labelling of BTK was confirmed via in-gel fluorescence (41B).
[0130] FIG. 45A-45E - Data showing elimination of inhibitor from ATP pocket. To demonstrate that the BTK inhibitor scaffold is released from the ATP -binding pocket, we used a reported assay based on Bioluminescence Resonance Energy Transfer (BRET) between a nanoluciferase (nanoLuc) and a fluorophore probe that binds to the ATP pocket; a higher occupancy of this ATP pocket by the inhibitor will prevent the binding of the tracer and lower the BRET signal (42A). As expected, acrylamide-based BTK inhibitors (42B, 42C) dramatically lower BRET signal indicating blocking of ATP-pocket, while their derivatives with cleavable methacrylamide linkers (alkynes or PHICS, 42D and 42E) did not affect binding of tracer. -In congruence with these findings, we observed higher autophosphorylation of BTK with PHICS compounds compared to the parent acrylamide inhibitors. Applicants have extended this approach to EGFR, FGFR, ITK, JAK3, and CDK2 kinases.

OVERVIEW
[0202] Small molecules have been classically developed to inhibit enzyme activity. Embodiments disclosed herein define new classes of chimeric small molecules that endow new functions to kinases via proximity-mediated effects. In general, the chimeric small molecules comprise an effector binding moiety connected to a substrate binding moiety via a linker. The chimeric small molecules can be used to improve the kinetics of native proteins modifications by bringing substrate molecules in proximity to the kinase, including using chimeric small molecule configurations that may be more favorable, energetically or otherwise. In addition, the chimeric small molecules may be used to re-target a protein to modify a non-native or neo-substrate.
[0203] In one aspect, chimeric small molecule can be configured to facilitate the covalent labeling of a protein with a target-binding moiety. The labeling of a kinase with a target binding moiety can be used to define new substrates not normally targeted or modified by such proteins. In such embodiments, the chimeric small molecule comprises a kinase binding moiety linked to a target binding moiety but further comprising an electrophilic reactive group. The kinase binding moiety non-covalently binds to the kinase of interest and, as a result, leads the electrophilic reactive group - via proximity-driven reactions - to “label” the protein by covalently binding the target binding moiety to a nucleophile located on the protein. In such embodiments, the kinase binding moiety is then released from the labeled kinase, either by inherent kinetics of the molecule or by application of a quencher. The target binding moiety may then direct the labeled kinase to bind and modify new target substrates. This approach also expands the number of kinase binders that may be used. For example, there are several high-quality kinase inhibitors that exist, but such inhibitors are unsuitable for use in targeting chimeras that remain bound to the kinase and thus may otherwise inhibit enzymatic activity of the bound kinase. As discussed in further detail below, selection of appropriate inhibitors, and the optional use of quenching molecules, allows these inhibitors to be used in the aforementioned labeling process without impacting the downstream modification reaction.
[0204] Embodiments disclosed herein provide targeting chimera designed for oncogenic targets. In one example embodiment, methods are provided for modification, for example, neo- phosphorylation, of oncogenic targets. Methods of use can comprise eliciting an immune reaction, creation of an autoantigen, and target deactivation. In an exemplary embodiment, hyper- phosphorylation or neo-phosphorylation of a target protein may result in immune recruitment to a target, for example via trigger display of neo-epitopes and T-cell attack on cells displaying the epitopes. Modification of kinases and key regulator proteins implicated in cancer are also within the scope of the methods disclosed herein.
[0205] Embodiments disclosed herein provide a method of modifying a target substrate in a cell is provided. For example, where the kinase binding moiety is a kinase and the target is a substrate located in a cell, then the kinase labeled with the target binding moiety can bind to the target substrate. The bound kinase can then neo-phosphorylate the target substrate even where a non-cognate substrate of the kinase, thereby modifying it.
[0206] Embodiments disclosed herein provide a method of recruiting a host’s immune system against cancer is provided. For example, where the target substrate is an oncogenic protein, then a kinase that has been labeled with an oncogenic target binding moiety using a chimeric small molecule can bind to the cancer through the oncogenic protein binding moiety. The bound kinase can then neo-phosphorylate the target oncogenic protein thereby signaling the host’s immune system to attack the cancer.
[0207] Embodiments disclosed herein provide a method of recruiting a host’s immune system against pathogen. For example, where the target substrate is located on the surface of a pathogenic bacteria, then a kinase that has been labeled with a pathogenic protein target binding moiety using a chimeric small molecule can bind to the bacteria through the target protein binding moiety. The bound kinase can then neo-phosphorylate the target pathogenic protein thereby signaling the host’s immune system to attack the bacteria.
CHIMERIC SMALL MOLECULES
[0208] In one example embodiment, the chimeric small molecule is according to the general formula A - Li - E- B or A -Li - E- L2 - B wherein A is a kinase binding moiety, B is a target binding moiety, Li and L2 are each a linker, and E is an electrophilic reactive group.
[0209] The embodiments of these formulae may be useful in, but not necessarily limited, to situations where the kinase binding moiety would otherwise inhibit or interfere with the ability of the kinase bound by the kinase binding moiety to modify the target substrate bound by the target binding moiety.
[0210] The electrophilic reactive group of the chimeric small molecule may be designed to react with a moiety on the kinase, for example, on an amino acid of the kinase. The electrophilic reactive group can be advantageously designed to react with a moiety in proximity to the binding site of the kinase binding moiety on the kinase. The reaction of the electrophilic reactive group with a moiety on the kinase, for example, a nucleophilic group of an amino acid disposed on the protein, can allow the labeling or binding of the kinase with the target binding moiety. Such binding of a target binding moiety to the kinase can generate a reprogrammed kinase that can modify a target substrate, including a target substrate other than the naturally occurring substrate of that kinase. Accordingly, in an example embodiment, the kinase binding moiety binds to the kinase and is chosen based on the binding pocket and availability of amino acid side chains in proximity to the binding pocket that may be used in a reaction with the electrophilic reactive group of the targeting chimera.
[0211] The kinase binding moiety may bind to a kinase and may be specific to one or more kinases. In an embodiment, the kinase binding moiety can further comprise a bio-orthogonal group. The kinase binding moiety, as detailed further herein, can be selected to have a half-life shorter than the half-life of the kinase.
[0212] The target binding moiety can be specific for one or more targets of interest. In one example embodiment, the target of interest is a macromolecule, e.g., a protein. The target binding moiety can bind the target of interest (target substrate), thereby bringing the kinase into proximity to the target of interest. In an embodiment, the target of interest may advantageously be a non- cognate substrate of the kinase. The target of interest may be a pathogenic or oncogenic target. Kinase Binding Moiety
[0213] The chimeric small molecule according to the general formula A - Li - E- B or A -Li - E- L2 - B comprises a kinase binding moiety A that may comprise any molecule capable of non- covalent bonding to a kinase. The kinase binding moiety, also referred interchangeably herein as a kinase binder, of the chimeric small molecule may target one or more different kinases, or one or more locations on the kinase.
[0214] A kinase belongs to a family of phosphotransferases and phosphorylates a substrate by transferring the gamma phosphate of ATP onto hydroxyl groups of the substrate. Substrates may comprise lipids, sugars or amino acids. The kinase binding moiety may be any molecule capable of binding to a kinase. Some kinase binding molecules are known to activate a kinase upon binding while others are known to inhibit a kinase upon binding. In one example embodiment, the kinase binding moiety is a kinase activator. In an example embodiment, the kinase binding moiety is a kinase inhibitor. However, binding of the kinase, rather than its inhibitory or activation behavior of the kinase binding moiety, is the primary objective as the design of the targeting chimeras generates a kinase labeled with a target binding moiety, with the kinase binding moiety utilized for initial binding to the kinase to allow for generation of a repurposed kinase labeled with target binding moiety rather than use of the kinase binding moiety for kinase activation or inhibition properties.
[0215] The chimeric small molecule is preferably designed such that one or more nucleophilic groups disposed on the protein, e.g., kinase, readily reacts with the electrophilic reactive group of the chimeric small molecule. The moiety comprising the nucleophilic group of the protein may be an amino acid side chain. Thus, the kinase binding moiety can be chosen based on the binding pocket and availability of amino acid side chains in proximity to the binding pocket that can be used in a reaction with the electrophilic reactive group of the targeting chimera. Further design of exit vectors that are comprised on the kinase binder or linker of the chimeric small molecule may further allow for desired configuration of the kinase binding moiety at the protein binding site.
Half-Life
[0216] In one example embodiment, where the chimeric small molecule is being used to label the surface of the kinase with a target binding moiety, the kinase binding moiety may be chosen in part based on its half-life. In one example embodiment, the kinase binding moiety may be chosen based in part on its half-life relative to the half-life of the kinase. In an embodiment, the half-life of the kinase binding moiety is 2, 3, 4, or 5 times shorter than that of the kinase. Without being bound by a particular theory, design of a chimera small molecule with a half-life of the kinase binding moiety shorter than that of the kinase may allow for desirable reaction kinetics when the kinase is labeled with the kinase binding moiety via the electrophilic reactive group. The half-life of the kinase binding moiety and the kinase generally relates to the time required for the concentration of the kinase binding moiety or kinase to decrease to half of its initial concentration. In one example embodiment, the half-life may measure the time it takes to degrade half of the molecules initially measured in a sample, which may comprise a cell, cells, tissue, organoid, or mammal, for example. In one example embodiment, the half-life of the kinase and the kinase binding moiety is measured in the same or similar conditions, for example, in a same cell type, tissue, or organism. In one example embodiment, the measurement of half-life can be measured in a same sample or system that has a particular phenotype, genotype, disease or condition to be studied, treated and/or evaluated.
[0217] Measurement of the half-life of the kinase binding moiety may be determined, for example, by dissociation ti/2 or receptor occupancy ti/2, describing the average time needed to liberate half of the initially occupied receptors under conditions in where association of the protein binding moiety or its rebinding can take place. Dissociation that requires a receptor conformational change or binding pocket size may play a factor in the residence time and can be considered when selected the protein binding moiety. See, e.g., Roskoski R Jr. Classification of small molecule protein kinase inhibitors based upon the structures of their drug-enzyme complexes. Pharmacol Res. 2016;103:26-48. Doi: 10.1016/j.phrs.2015.10.021.
[0218] The time a compound resides on its target, e.g., residence time, may be used. See, Willemsen-Seegers N, Uitdehaag JCM, Prinsen MBW, et al. Compound Selectivity and Target Residence Time of Kinase Inhibitors Studied with Surface Plasmon Resonance. J Mol Biol. 2017;429(4):574-586. Doi: 10.1016/j.jmb.2016.12.019, for discussion and identification of residence time and kinetic parameters of exemplary kinase binding moieties, incorporated herein in its entirety, and in particular Table 1,3A-3B, 4A-4C, S3 and S4, for teachings to tyrosine kinase inhibitors, EGFR inhibitors, ponatinib to a variety of kinases, particular kinases and their associated inhibitors, Aurora A and B kinase inhibitors, and P13k lipid kinase inhibitors. Elimination half-life may also be utilized alone or in conjunction with residence time evaluation. Additional pharmacodynamics and pharmacokinetics may also be considered in the evaluation of half-life for the kinase binding moiety. Half-life may be modeled. See, e.g., Callegari D, Lodola A, Paia D, et al. Metadynamics Simulations Distinguish Short- and Long-Residence-Time Inhibitors of Cyclin-Dependent Kinase 8 [published correction appears in J Chem Inf Model. 2017 Feb 27;57(2):386], J Chem Inf Model. 2017;57(2): 159-169. Doi:10.1021/acs.jcim.6b00679, incorporated herein by reference.
[0219] The measurement of half-life of the kinase, approaches measuring half-life such as mass spectrometry-based proteomics such as SILAC (stable isotope labeling by amino acids in cell culture)-based proteomics, see, e.g., Matheison et al., Nature Communications volume 9, Article number: 689 (2018), may be used. High throughput proteomics may be used to estimate a kinase half-life in a particular tissue and/or cell, or further predictive modeling may be used to predict such kinase half-life in tissue from cellular properties, see, e.g., Rahman M, Sadygov RG Predicting the protein half-life in tissue from its cellular properties. PloS ONE 12(7): e0180428. Doi.org/10.1371/journal.pone.0180428 (2017).
[0220] The kinase binding moiety can be chosen based on the target substrate and the modification to that substrate desired. Advantageously, the kinase binding moiety can be an activator or inhibitor of the kinase. An kinase binding moiety may be chosen based on high kinase abundance in a target cell; kinases with high activity at lower concentrations, e.g., nanomolar activity; available crystal structure and characterization of the kinase active; kinase binding moieties with low residence time; the ability of the kinase binding moiety of the chimeric small molecule to accommodate a bio-orthogonal group, e.g., a small biorthogonal handle, without affecting binding potency and/or residence time; kinases with a high density of amino acids with nucleophilic side chains, e.g., serines/threonines/tyrosines/lysines close to the binding pocket; and/or whether the labeling of the kinase would interfere with its enzymatic activity, which may be based on experimental data and/or modeling. Linker length on the chimeric small molecule may be tuned, allowing modification, e.g., phosphorylation, with increased distance from binding pocket, allowing modification to be targeted to locations, for example, amino acid residues, farther away from the binding pocket. For example, a longer linker length can be utilized when a bioconjugation reaction is desirable further away from a binding pocket but optimized for a length that still allows the target binding moiety, once bound to a target substrate in close proximity to the binding pocket of the kinase. Tuning linker length may also include a level of flexibility or rigidity depending on desired configuration of the target binding moiety for modifications of amino acid residues. A shorter linker length may allow for modification within the binding pocket which may desirable for some applications.
[0221] In an example embodiment, the kinase binding moiety is an allosteric modulator. Considerations in selecting a kinase binding moiety may include allosteric signaling, which may include changes associated with networks of non-covalently interacting protein residues, conformational selection, and induced fit with both spatial and temporal aspects. In one example embodiment, the kinase binding moiety may be an allosteric activator or inhibitor of the kinase. Allosteric activators or inhibitors may be discovered computationally. In one example method, high quality drug targets are acquired. Then allosteric site prediction is performed using methods such as perturbation response scanning (PRS) combined with all-atom molecular dynamics (MD) and dynamic residue networks (DRN). Allosteric modulators are then identified using methods such as homology modeling, docking, or essential dynamics. An illustration of this process can be found in Figure 2 and 3 of Amamuddy S., et al. Integrated Computational Approaches and Tools for Allosteric Drug Discovery. 21 UMSIMI (2020), incorporated herein by reference.
[0222] Kinase binding moieties may be chosen based on the type of desired modification to be made by the kinase, for example, post-translational modification of the target substrate. In one example embodiment, the kinase binding moiety is capable of binding a kinase that phosphorylates a target, thus the type of kinase may be chosen for this desired modification of a target substrate. Post-translational modification (PTM) is one type of modification performed. Accordingly, post- translational modification kinases are one set of kinase binding moieties envisaged for use in the present invention.
[0223] In one example embodiment, the kinase binding moiety provides a modification to an amino acid, see, e.g., for example Table 1 of Karve et al., Journal of Amino Acids Volume 2011, Article ID 207691, 13 pages, DOI: 10.4061/2011/207691, incorporated herein by reference. Karve et al. summarizes some post-translational modifications and their importance in various diseases as well as normal development. Karve et al. assesses, phosphorylation of amino acids, and is incorporated specifically for the phosphorylation modifications detailed therein. [0224] The reaction of the electrophilic reactive group with a moiety on the kinase, for example, a nucleophilic group disposed on the kinase, can allow the labeling or binding of the kinase with the target binding moiety. Such binding of a target binding moiety to the kinase can generate a reprogrammed kinase that can modify a target substrate. Accordingly, in an example embodiment, the kinase binding moiety binds to the kinase and is chosen based on the binding pocket and availability of amino acid side chains in proximity to the binding pocket that may be used in a reaction with the electrophilic reactive group of the targeting chimera.
Example Kinase Bindins Moiety
[0225] In an example embodiment, the kinase binding moiety is a kinase activator moiety. The kinase activator moiety can be a small molecule or compound that activates a kinase. As used herein, a kinase is an enzyme that adds a phosphate group to another molecule, typically an amino acid of a protein substrate. An activator of a kinase enhances such phosphorylation activity. In one example embodiment, the kinase activator moiety promotes an active conformation of an enzyme, in one aspect, trough binding interactions with regulatory subunits. See, e.g., Zorn et al Nat Chem Biol. 2010 Mar;6(3): 179-188; doi: 10.1038/nchembio.318. The kinase may act on the amino acid serine, threonine, tyrosine, or a combination thereof.
[0226] Activator moieties can be identified from activators known in the art. The activators may be a derivative of activators known in the art and may comprise fewer or additional functional groups that still permit activator activity, but may enhance or facilitate the desired formation, conformation or attachment sites for the chimeric small molecules described herein. Exemplary modifications may include derivatives for increase solubility, charge, functionality for use with an orienting adaptor or linker, detailed elsewhere in the specification.
[0227] In one embodiment, the kinase binding moiety is a kinase inhibitor. A kinase inhibitor (KI) is generally designed to bind with a highly conserved Asp-Phe-Gly (DFG) motif of a kinase. Kis can be classified by the conformation of the DFG binding site. Type I bind to the active, DFG- Asp-in, conformation while Type II inhibitors bind to the inactive, DFG- Asp-out, conformation. Further consideration of kinase inhibitors include competition with ATP -binding, which may include mimicking the hydrogen binding interactions normally formed by the adenosine ring of ATP, or the mechanism of inhibition such as reversible binding or irreversible covalent bonding. See e.g. (Gross et al. J Clin Invest. 2015;125(5): 1780-1789) [0228] A consideration of kinase inhibitor design has been the degree of specificity to a particular kinase. While the assumed advantage has been for more specificity, kinase inhibitors with a low degree of specificity for a particular kinase facilitates the recruitment of many types of kinases. A promiscuous kinase inhibitor is advantageous as the kinase is a vehicle for the modification of the target substrate.
[0229] In one embodiment, the protein binding moiety is a promiscuous kinase inhibitor (PKI). A promiscuous kinase inhibitor refers to a molecule that binds to more than one kinase. A promiscuous kinase inhibitor is a molecule that has binding specificity to a binding pocket with high conservation across kinases. A promiscuous kinase inhibitor may bind to 2, 3, 4, 5 or more different kinases. In one example embodiment, the promiscuous kinase inhibitor is an ATP- competitive kinase inhibitor. In one example embodiment, the PKIs target one or more kinases selected from PDGFRA, PDGFRB, KIT, CSF1R, DDR1, DDR2, MEK5, and YSK4. See, e g., Seeliger, M. A., et al. “What Makes a Kinase Promiscuous for Inhibitors?” Cell Chem. Biol., 26 (3), 2019; 390-399. For example, the kinase inhibitor imatinib can inhibit c-KIT, PDGFR-alpha and BCR-ABL kinases (see, e.g., Iqbal N, Iqbal N. Imatinib: a breakthrough of targeted therapy in cancer. Chemother Res Pract. 2014;2014:357027. Doi: 10.1155/2014/357027. Epub 2014 May 19); similarly, sunitinib, sorafenib, and cabozantinib are also known for their promiscuous activity and are provided as non-limiting examples of promiscuous kinase inhibitors. In one example embodiment, the PKI is modified to contain a bio-orthogonal group.
[0230] In one example embodiment, the protein binding moiety is a kinase binding moiety. Example kinases that may be bound by the chimeric small molecules of the present invention include, but are not limited to, PK, PKC, AMPK, MAPK, EGFR, FGFR, NGFR, TrkA, ABL, BCKDK, CDK, PI3K, VEGFR, BRAF, MEK, AKT, ALK, BTK, FLT3, JAK2, AURKA, c-MET, DDR, FKBP, INSR, IKK, JNK, mTOR, PAK, PDK1, PDK2, PTK2/FAK, pyruvate kinases, RAC- oc, RIPK, TYK2, SHP, aPKC, NOP, p (mu) opioid receptor, 5 (delta) opioid receptor, UMPK, SphK, or GSK-3.
ABL Binding Moiety
[0231] In one example embodiment, the protein binding moiety is an ABL kinase binding moiety. Abelson kinases (ABL) is a ubiquitously expressed, nonreceptor tyrosine kinase which plays a key role in cell differentiation and survival. Simpson, etal., J. Med. Chem. 201962, 2154- 2171. ABL tyrosine kinase can be found in the nucleus, cytoplasm, and mitochondria. ABL proteins are normally under well-orchestrated regulation. However, chromosome translocations that join the ABL genes with genes coding for other proteins give rise to various fusion proteins that are prone to dimerization (or oligomerization) and autophosphorylation. Consequently, ABL kinase becomes constitutively active, leading to myeloproliferative disorders. In one example embodiment, one of the ABL kinase binding moieties as detailed herein is used with a target binding moiety as described herein in a chimeric small molecule.
[0232] In one example, embodiment, the ABL kinase binding moiety is an ABL kinase activator. In one example embodiment, the c-Abl Kinase activator is (5-[3-(4-fluorophenyl)-l- phenyl-lH-pyrazol-4-yl]-2,4-imidazolidinedione or 5-(l,3-diaryl-lH-pyrazol-4-yl)hydantoin):

[0235] In one example embodiment, the c-Abl kinase binding moiety is a (5-[3-(4- fluorophenyl)- 1 -phenyl- lH-pyrazol-4-yl]-2,4-imidazolidinedi one or 5-(l,3-diaryl-lH-pyrazol-4- yl)hydantoin) (DPH) derivative according to the formula

GNF-2 inhibits the Bcr/Abl fusion protein with an IC50 value of 267nM.

GNF-5 is a selective and allosteric BCR-ABL inhibitor. GNF-5 can largely overcome the resistance patterns associated with imatinib or nilotinib treatment (except for the gatekeeper mutation T3151). Co-treatment with GNF-2 (GNF-5’ s original structural incarnation) plus imatinib significantly decreases the emergence of resistant clones in vitro. GNF-5 downregulates BCR- ABL kinase activity by mimicking the effect of myristate binding, which directs the protein towards adopting an inactive conformational state. GNF-5 has pICso of 6.7 for ABL proto- oncogene 1, non-receptor tyrosine kinase. See e.g., Deng, X., et al. “Expanding the Diversity of Allosteric Bcr-Abl Inhibitors.” J. Med.

[0406] In an embodiment, the protein is an insulin receptor, and the binding moiety is RZ-358, also known as XOMA-358 that is fully human negative allosteric modulating insulin receptor antibody. RZ358 can be intravenously administered and binds to a site on the insulin receptor present in the liver, fat and muscle. The RZ358 molecule has high selectivity to the insulin receptor with no IGF-1 interaction and still allows insulin to bind and signal, dampening the insulin signal only when insulin is elevated. Clinical trials have been performed with dowing ranging from 0.1 to 9 mg/kg and has been studied in congenital hyperinsulinism and Post-gastric bypass hypoglycemia. [0407] Additional selective allosteric antibodies to the Insulin receptor, including XmetD have been identified using a research platform and can be utilized in small molecules disclosed herein.

[0412] The FKBP12-sirolimus complex is reported to bind to a site distinct from the kinase domain of mTOR and acts as a negative allosteric modulator of mTOR activity. This action reduces mTOR-induced proliferation of activated T-cells, the cells which would normally be involved in the immunological attack on transplanted tissue. See, Am. J. Health-Syst. Pharm. 2000, 57, 437- 448. In vitro studies have been performed and these show that sirolimus inhibits MERS-CoV infection of Huh7 cells. This mechanism could also be applied to SAR-CoV-2 infection.

Phosphoinositide-dependent protein kinase-1 (PDK1) regulates the AGC family of kinases. PDK1 comprises three ligand binding sites: the substrate binding site, the catalytic ATP binding site, and the PDK1 Interacting Fragment (PIF) binding site. The PIF binding site, which is hydrophobic, has two functions: the recruitment of the downstream substrate kinases harboring the hydrophobic motif (HM) and the stimulation of the intrinsic activity of PDK1. See e.g. “The Chemical Diversity and Structure-Based Discovery of Allosteric Modulators for the PIF-Pocket of Protein Kinase PDK1.” Journal of Enzyme Inhibition and Medicinal Chemistry 2019, 34 (1), 361-374.

IRE Binding Moiety
[0454] serine/threonine-protein kinase/endoribonuclease inositol-requiring enzyme 1 a (IRE) is an ER transmembrane protein containing two enzymatic activities, a kinase and an endoribonuclease (Rnase). During ER stress the ER luminal domain becomes oligomerized and the ER protein unfolds. Oligomerization causes rearrangement of the two enzymatic domains resulting in trans-autophosphorylation. The Rnase cleaves XBP1 mRNA to release an intron. The open reading is then shifted after re-ligation of the cleaved XBP1 mRNA. A transcription factor called XBPls is produced by the translated spliced XBP1 mRNA. ER protein folding and capacity and quality control is enhanced by a XBPls protein. Therefore, IRE promotes adaptation of the ER.

Target substrates polypeptides, a nucleic acid, polynucleotides, lipids, and oligosaccharides. The target binding moiety may be chosen for a specific substrate of interest, which may be located in different localization sites of the cell, e.g., nucleus, cytoplasm, mitochondria, cell surface.
Target Binding Moiety
[0458] The target binding moiety equips the chimeric small molecule with a mechanism to bind or associate with a target, including the target substrates noted above. The target binding moiety of the chimeric small molecule binds the target substrate and brings the target substrate into proximity with a kinase via the kinase binding moiety or by virtue of the target binding moiety bound or labeled on the kinase. The reaction can allow the protein to modify a larger number of substrates, non-natural target substrates of the protein, and to increase the kinetics/efficiency of such substrate modifications. For that purpose, the target binding moiety should be capable of binding the desired substrate of interest and capable of being linked to a kinasebinding moiety via a linker to allow for modification of the substrate.

Small molecules that target polynucleotides include groove binders and intercalators, see e.g., Wang M., et al. “Recent Advances in Developing Small Molecules Targeting Nucleic Acid.” UMS 2016, 17 (6), 779 and Warner K. D., et al. “Principles for Targeting RNA with Drug-like Small Molecules.” Nat Rev Drug Discov 2018, 17 (8), 547-558, herein incorporated by reference. Additional example polynucleotide binding moieties include polynucleotide binding proteins. Polynucleotide binding proteins can be identified from nucleotide-binding folds in the proteins, such as the Rossmann- type (see, e.g., Kleiger et al., J. of Mol. Biol. 323: 69-76) and the P-loop containing nucleotide hydrolase folds (see, e.g., Saraste et al., Trends in Bio Sci, 15: 430-434). Chauhan et al. has developed methods for the identification of ATP and GTP binding residues and Ansari et al. has designed a method specifically for NAD. Parca et al. (2012), identified nucleotide-binding sites in protein structures, and include nucleotides bound by the protein, protein name and name of organism in Table SI of DOI: 10.1371/journal. pone.0050240, incorporated herein by reference. Accordingly, nucleotide binding moieties are known in the art and can be identified by one of skill in the art for use as a target binding moiety in the present compositions.
Oligosaccharide Bindins Moieties
[0460] In one example embodiment, the target binding moiety is an oligosaccharide binding moiety. Oligosaccharide binding moieties include small molecules. For example, small molecules that include boronic acid are typically used to bind to oligosaccharides. See e.g., Jin S., et al., “Carbohydrate Recognition by Boronolectins, Small Molecules, and Lectins”. Med. Res. Rev. 2009, herein incorporated by reference. Other oligosaccharide binding moieties include carbohydrate binding proteins, are important targets when considering antiviral and anticancer drugs. The localizing moiety can be, for example, a lectin, facilitating interaction sites for carbohydrates. Exemplary molecules include small molecule boronolectins, nucleic acid-based boronolectins, and peptidoboronolectins. See, e.g., Jin et al., Med. Res Rev. 2010 March; 30(2):
171-257; doi: 10.1002/med.20155, incorporated herein by reference, specifically Figures 1-50 for binding molecules and the complexes formed. Publicly available computational methods are available using developed bioinformatics to select small molecules capable of binding carbohydrates, see, e.g. , Zhao et al., Current Protocols in Protein Science 94: 1 10.1002/cpps.75; Shionyu-Mitsuyama C, Shirai T, Ishida H, Yamane T (2003) Protein Eng 16: 467-478; and Kulharia M, Bridgett SJ, Goody RS, Jackson RM (2009) InCa-SiteFinder: a method for structure- based prediction of inositol and carbohydrate binding sites on proteins. J Mol Graph Model 28: 297-303.
[0461] Analysis of binding site residues along with stabilizing residues in protein- carbohydrate complexes can allow for identification of folding and binding of the complexes to understand interactions in addition to non-covalent interactions of hydrogen bonding and non- polar interactions. See, e.g., Shanmugam et al., doi.: 10.2174/0929866525666180221122529. Utilizing publicly available tools, carbohydrate binding moieties, including binding sites and predicted folding can be used for the design of chimeric small molecules comprising such a carbohydrate binding moiety.
Lipid Binding Moieties
[0462] In one example embodiment, the target binding moiety is a lipid binding moiety. Lipid binding moieties can be utilized as target binding moieties in the chimeric small molecules disclosed herein. As regulators of cellular stabilization and signaling, modifications in their composition, distribution or trafficking would be useful in treatment, regulation and/or modification of pathways, processes and conditions. Lipids include charged lipids, e.g., phosphatidyl serine (PS), phosphatidic acid (PA), phosphatidylinositol (PI), and the PI- phosphate, -bisphosphate, and -trisphosphate (PIPs - a family of seven anionic charged lipids), and ganglioside (GM). Zwitterionic lipids, e.g., phosphatidylcholine (PC), phosphatidylethanolamine (PE), and sphingomyelin (SM) lipids, Ceramides (CER), diacylglycerol (DAG), and lysophosphatidylcholine (LPC) lipids, sphingolipids, glycerophospholipids, cholesterol , phosphati dylgly cerols .
[0463] Lipid binding moieties may be incorporated into chimeric small molecules. For example, certain steroids are capable of targeting and binding to lipids. Other lipid binding moieties such as proteins can either bind lipids specifically, where a clear binding site for a given lipid can be identified, or nonspecifically, where lipids act as a medium, and physical properties like thickness, fluidity, or curvature regulate the protein function. Phosphoinositide binding domains such as FYVE or PX, or the FRRG motif in the P-propeller of PROPPINs are more common domains that can be used to identify lipid binding proteins. The FYVE domain, named after the first four proteins to contain the motif (Fabl, YOTB, Vacl EEA1) contains several conserved regions, which can also be utilized to identify related domains. See, e.g., A.H. Lystad, A. Simonsen Phosphoinositide-binding proteins in autophagy, FEBS Lett., 590 (2016), pp. 2454- 2468, 10.1002/1873-3468.12286. Additional FYVE domain-containing proteins include SARA, FRABIN, DFCP1 FGD1, ANKFY1, EEA1 FGD1, FGD2, FGD3, FGD4, FGD5, FGD6, FYCO1, HGS MTMR3, MTMR4, PIKFYVE, PLEKHF1, PLEKHF2, RUFY1, RUFY2, WDF3, WDFY1, WDFY2, WDFY3, ZFYVE1, ZFYVE16, ZFYVE19, ZFYVE20, ZFYVE21, ZFYVE26, ZFYVE27, ZFYVE28, ZFYVE9.

Accordingly, autophagy related (ATG) proteins may be utilized as lipid binding moiety in the present invention, including LC3A, LC3B, LC3C, GABARAP, GABARAPL1 and GABARAPL2. De la Ballina (2019), doi.org/10.1016/j.jmb.2019.05.051.

[0466] The target protein binding moiety may be chosen for a specific protein of interest, which may be located in different localization sites of the cell, e.g., nucleus, cytoplasm, mitochondria, cell surface.

The target protein binding moiety may bind to proteins which undergo conformation change upon binding.
[0467] The target protein binding moiety may bind to proteins which undergo conformation change upon binding, for example, an androgen receptor (AR). In one embodiment, activation of the protein results in modification of the target substrate by the protein at one or more new modification sites that would otherwise remain unmodified by the protein when not activated by the chimeric small molecule. The target substrate is not required to be a natural substrate of the protein. The target substrate may be a protein, and discussion herein of genes includes the products of the gene expression.
[0468] In one embodiment, the target protein binding moiety is capable of binding a protein that is an ATPase or GTPase. Exemplary GTPases may be from the Ras, Rho, Rab, Arf or Ran family, see, e.g. Yoshimi Takai, Takuya Sasaki, and Takashi Matozaki, Small GTP -Binding Proteins, Physiological Reviews 2001 81 : 1, 153-208; doi:
10.1152/ohysrev.2001.81.1.153. Exemplary molecules targeting may include molecules such as Ibrutinib (BTK), Dsatinib (BCR-ABL), MRTX (KRAS), MI-1061 (MDM2), Gelfitinib (EGFR), Palbociclib (CDK4/6) and Foretinib (C-MET), or analogs thereof.

[0495] In one example embodiment, the molecules or binding moieties as disclosed herein may be modified to include an electrophilic reactive group. In one embodiment, the electrophilic reactive group is located between the linker and target binding moiety. In an embodiment, the electrophilic reactive group is located between two linkers, a first linker attached to the kinase binder and a second linker attached to the target binding moiety. An electrophilic reactive group, as used herein, is typically a functional group that can form a reversible or irreversible bond with a nucleophilic functional group. The electrophilic reactive group allows for the target binding moiety to directly attach to the target kinase. Upon attaching to the electrophilic reactive group, the kinase is now tagged with the target binding moiety. In one example embodiment, the molecules or binding moieties may be modified at an electrophilic reactive group to reduce or lessen the strength of covalent binding capabilities of an electrophilic reactive group, or to increase the binding affinity or strength of binding of an electrophilic reactive group as desired according to the application. In an embodiment, a binding molecule may be chosen that would create irreversible covalent binding at a target. When used in a chimeric small molecule, such tight bonding may be less desirable. Thus, modification of such electrophilic reactive group would be desirable and can be modified to reduce the interaction, see, e.g., sciencedirect.com/science/article/pii/S0968089618320807. In particular, reactivity can be designed to allow for covalent binding at the target, with reversible or irreversible properties, depending on desired functionality. In an embodiment, the electrophilic reactive group is designed to react with an amino acid side chain reactive group. The amino acid side chain reactive group may be nucleophilic. The nucleophilic amino acid side chain reactive group may comprise arginine, lysine, histidine, cysteine, aspartic acid, glutamic acid and tyrosine. In one preferred embodiment, the electrophilic reactive group reacts with lysine. An exemplary database that can aid in identification for protein ligand interaction around the binding site is described in Du et al., Nucleic Acids Research, Volume 49, Issue DI, 8 January 2021, Pages D1122-D1129, incorporated herein by reference, with the database, CovalentlnDB accessible at cadd.zju.edu.cn/cidb/. The approach can be used with any design of the electrophilic reactive group for molecules as disclosed herein.

[0496] NASA chemistry may be used to accomplish the design of the electrophilic reactive group by forming a reversible or irreversible bond with a nucleophilic functional group located on the kinase. NASA chemistry is generally described in Nat Commun 9, 1870 (2018), incorporated herein by reference. In preferred embodiments, the kinase binding moiety can be attached to a linker utilizing /V-acyl A- -alkyl sulfonamide (NASA) electrophilic reactive group further attached to a kinase binding moiety. The chimeric small molecule containing a NASA will, upon non- covalent binding to a target enzyme, covalently bond to the enzyme as the NASA chemically reacts with a proximal lysine or other amino acid as described herein. The NASA modified chimeric small molecule then disassociates from the kinase leaving behind the protein targeting binder covalently attached to the kinase. This modified kinase will then bind to the target protein through the newly attached binder and further modify the protein. In an example embodiment, NASA chemistry is used to label a kinase binding moiety. Accordingly, an embodiment comprises methods of making compositions disclosed herein using NASA chemistry, and as further described in the examples.

When more than one linker molecule is used in a molecule, the linkers may be the same or different from each other.
[0509] In one example embodiment, the linker may be represented with an exit vector. In one example embodiment, the exit vector may be represented independently of the linker. Exit vector parameters can be identified in part based on average orientation of a substituent attached to a variation point which can be generated using chemoinformatics software. An exit vector may comprise outgoing bonds from a chemical moiety. In an embodiment, the exit vector is provided as bonds on the linker or from the binding moiety, providing conformation of attachment between the linker and the activator moiety and/or the localizing moiety.
Exit Vectors
[0510] One or more exit vectors may be utilized with the molecules described herein. In certain embodiments, the linker or kinase binding moiety may be represented with an exit vector comprised in the linker or kinase binding moiety. In an embodiment, the exit vector may be represented independently of the linker or kinase binding moiety. Exit vector parameters can be identified in part based on average orientation of a substituent attached to a variation point which can be generated using chemoinformatics software. An exit vector may comprise outgoing bonds from a chemical moiety. In an embodiment, the exit vector is provided as bonds on the linker or from an Abl binding moiety, providing conformation of attachment between the linker and the Abl binding moiety and/or the second Abl binding moiety.

[0512] In one example embodiment, the kinase binding moiety has an adapter or reactive handle, both used herein interchangeably. The reactive handle comprises the group on the kinase binding moiety that attaches to the linker. In one example embodiment, the reactive handle can perform click chemistry, amide coupling chemistry, crosslinking chemistry, alkylation, or sulfonation chemistry. (See e.g., I, K.; Brechbiel, M. W. Growing Applications of “Click Chemistry” for Bioconjugation in Contemporary Biomedical Research. Cancer Biotherapy and Radiopharmaceuticals, 2009, 24, 289-302.)
[0513] In one example embodiment, the bond is chosen to be energetically favorable, preferably increasing binding affinity. The exit vector may be adjusted depending on the linker utilized in the molecules. In one example embodiment, the exit vector is a chemical moiety or bond that facilitates stereochemical protrusion that may further facilitate subsequent coupling, bonding and/or accessibility.
[0514] In an embodiment, L is a rigid linker, which may be selected from the group consisting
Figure imgf000192_0001
; or any combination thereof; and wherein any atom in within a ring may substituted for C, N O, S; the linkers may bond to one or more PEG molecules before bonding to A and optionally B; and m and n may be independently selected from 0 to 6.
[0515] In preferred example embodiments, the linker L has one covalent attachment point to a kinase binding molecule and two covalent attachment points to the other kinase binding molecule. A covalent attachment point may be any single, double, triple, or quadruple bond between one component of the BFM/chimeric small molecule and another. In preferred example embodiments, the linker is attached to one kinase binding molecule, i.e. A, and the other, i.e. B, according to the formula

In one example embodiment, the reactive handle can perform click chemistry, amide coupling chemistry, crosslinking chemistry, alkylation, or sulfonation chemistry.
Bio-Orthogonal Group
[0519] The chimeric small molecules disclosed herein may further comprise a biorthogonal group. A chimeric small molecule may be configured to include a bio-orthogonal group as a device to remove the kinase binding moiety from the target kinase. This occurs when a coupling molecule, selected to react with the biorthogonal molecule, is introduced into the system containing the kinase bound chimeric small molecule and bonds to the bio-orthogonal group. As a result, the kinase binding molecule is no longer operable and cannot bind to the target kinase. In one example embodiment, the kinase binder comprises a bio-orthogonal group. In one example embodiment, the kinase binder is modified to contain a bio-orthogonal group. Bio-orthogonal chemistry comprises chemical reactions carried out in a biological environment without reacting with endogenous systems, such as functional groups. Bio-orthogonal groups comprise moieties capable of bio-orthogonal chemistry. Non-limiting examples of bio-orthogonal groups include tetrazines, triazines, cyclooctenes, cyclopropenes and diazo groups.
[0520] In one example embodiment, the bio-orthogonal group comprises one of

ELECTROPHILICALLY REACTIVE LINKERS
[0521] In another aspect, embodiments disclosed herein are directed to an electrophilic linker having enhanced stability, reactivity, and tuneability. In one example embodiment the linker molecule has the formula formula Li-El, EL-Li, or L1-EI-L2, wherein Li and L2 are independently selected from alkane, alkene, amine, either, thiol, sulfone, carbonyl, acyl, ketone, carboxylate ester, amide, enone, anhydride, imide, and PEG, and wherein EL is an electrophilic reactive group. The electrophilically reactive linkers may be used to attach all or a portion of Li or L2 to a target polypeptide. The El group of the linker molecule may be selected based on an ability to covalent attach all or a portion of Li or L2to a cysteine, a lysine, a methionine, or a tyrosine residue on the target polypeptide. In one example embodiment Li and L2 may independently be any of the linkers described above.

Use of Electrophilically Reactive Linker Groups
[0527] The electrophically reactive linkers disclosed in this section may be used in any bifunctional molecule, including the chimeric molecules disclosed in this application. The electrophilically reactive linkers may also be used in other bifunctional molecules such as PROTACS. Bekes et al. “PROTAC targeted protein degraders; the past is prologue” Nature Review Drug Discovery 21, 181-200 (2022). In addition, the electrophically reactive groups may also be used with other bifunctional molecules. For example, a target polypeptide binding moiety may be attached to one of the linkers and a modifying moiety may be attached to the other end of the linker. The target polypeptide binding moiety may be selected to selectively bind a target polypeptide, such as an enzyme, at a catlyical or allosteric site to allow for the electrophilically reactive linkers disclosed herein to covalently attach the modifying moiety to the target polypeptide at cysteine, lysine, methionine, or tyrosine. In one example embodiment, the target polypeptide binding moiety is a binding moiety capable of specifically binding a phosphatase, a ubiquitinase, a deubiquitinase, an acetyltransferase, deactylase, methyltransferase, demethylase, or glycosyltransferase and the modifying moiety binds a neo-substrate for the kinase, a phosphatase, a ubiquitinase, a deubiquitinase, an acetyltransferase, deactylase, methyltransferase, demethylase, or glycosyltransferase. In another example embodiment, the modifying moiety is an immunogenic moiety and the target polypeptide binding moiety is a polypeptide to which the immunogenic moiety is to be attached.

Methods of Use
[0548] In another aspect, chimeric small molecules as described above may be used in methods to endow new functions to cellular kinases or to regulate the activity of cellular kinases. The chimeric small molecules find use for treatment in a variety of diseases and disorders. In an example embodiment, a target binding moiety can bind to a target of interest, preferably localizing in a region of a target of interest, allowing the protein to which the protein binding moiety is bound to modify a target. Exemplary applications include use in rewiring of cellular signaling. See, Lim et al., Nat Rev Mol Cell Biol 2010, 11(6), 393-403. For example, cell signaling can be addressed by appending phosphoryl groups to specific signaling protein of interest with dose and temporal control to allow rewiring of kinase signaling pathways in disease or health. The chimeric small molecule systems herein may enable targeted degradation of a target where phosphorylation sites are targets that recruit ubiquitin ligase and signal degradation. See, Toure et al., Angewandte Chemie (InterT ed. In English) 2016, 55(6), 1966-73. Similarly, preventing protein aggregation can aid in treatment in cancer treatment approaches. As described herein, addition of negatively charged phosphoryl groups using the chimeric small molecules on a protein prone to aggregation may increase solubility and reduce self-aggregation. Guo et al., FEBS Letters, 2005, 579 (17), 3574-3578; Zhang et al., Protein Expression and Purification 2004 36(2) 207-216. Exemplary embodiments comprising methods of treatment of kinasopathies are also provided. Exemplary embodiments further include regulation of nucleotide binding proteins, which may include use with orthogonally tagged nucleases such as Cas, and phosphorylation of transcription factors to affect binding. In one example embodiment, the invention described herein relates to a method for therapy in which cells are modified ex vivo by the chimeric small molecules to modify at least one target substrate, with subsequent administration of the edited cells to a patient in need thereof.
Methods of Modifying Target Substrates
[0549] The chimeric small molecules disclosed herein can be utilized in methods of modifying a target substrate. Methods of modifying the target substrate can include generating a repurposed/reprogrammed cellular protein by delivering a chimeric small molecule, as described herein. In an example embodiment, the chimeric small molecules can be used to inhibit nucleotide binding proteins, inhibit oncogenic kinases, generate neo-antigens to evoke an immune response, as molecule prosthetics of kinasopathies, treatment of pathogens and induction of receptor tyrosine kinase signaling.
[0550] Methods of modifying a substrate are provided, which may be in a cell. In one example embodiment, a chimeric small molecule as described herein is introduced. In one example embodiment, the modifying comprises inducing post-translational modification of a target protein. In one example embodiment, the post-translational modification is phosphorylation. The method comprises administering to cell or cell population a chimeric small molecule. Methods of modifying the target substrate can include contacting the target substrate with a chimeric small molecule, e.g., bifunctional molecule, of the present invention. Contacting can allow for bonding to, or association with the target substrate, or to a molecule in proximity to a target substrate. Modification may be by inducing a conformational change via binding, changing structural stability, phosphorylation of a target, or via another mechanisms that affects the behavior of the target substrate. By way of example, activation or inactivation of the target substrate via the binding of the chimeric small molecule results in modification of the target substrate one or more new modification sites that would otherwise remain unmodified when the chimeric small molecule is not bound to the target substrate. In an aspect the methods comprise inducing phosphorylation of a target protein in the cell. The methods may comprise contacting a target substrate with the chimeric small molecule. [0551] In an example embodiment, the chimeric small molecule can label the cellular protein with the target binding moiety for the target substrate via the electrophilic reactive group moiety. The electrophilic reactive group reacts with and bonds to a nucleophilic side chain on the cellular kinase. Labelling of the cellular kinase can allow for bonding to, or association with, the target substrate, or to a molecule in proximity to a target substrate facilitating modification of the target substrate. In one example embodiment, this approach allows utilization of protein inhibitor moieties, as well as activators and neutral binding molecules to induce target modification. Such kinase binding moieties tethered with an electrophilic reactive group, e.g., a chemoselective electrophilic warhead, exhibits site-specific labeling of a side chain nucleophilic residue, e.g., nucleophilic side chain amino acid, proximal to the inhibitor binding site. Generally, labeling proximal to the inhibitor binding site refers to a reactive group at, within, or at a distance to the binding moiety binding site that allows the electrophilic reactive group to react at or near the time and/or space of the binding site of the binding moiety. The tethering of the electrophilic warhead can comprise a linker, bond, and/or exit vector or adapter which may, in some instances, In one aspect, the target substrate is not a natural substrate of the protein, or wherein activation of the protein by the binding moiety results in modification of the target substrate by the protein at one or more new modification sites that would otherwise remain unmodified by the protein when not activated by binding to the activator moiety. Modification may be by inducing a conformational change via binding, changing structural stability, phosphorylation of a target, or via other mechanisms that affects the behavior of the target substrate, e.g., removal of groups such as phosphatases, methyltransferases. Modifying can include the post-translational modification as disclosed herein, including, for example, phosphorylation, hydroxylation, acetylation, methylation, glycosylation, prenylation, amidation, eliminylation, lipidation, acylation, lipoylation, deacetylation, formylation, S-nitrosylation, S-sulfenylation, sulfonylation, sulfinylation, succinylation, sulfation, carbonylation, or alkylation. In one aspect, the methods comprise inducing phosphorylation of a target protein in or on the cell. The methods may comprise contacting a target substrate with the chimeric small molecule. In one example embodiment, the target substrate is in proximity to a kinase specific to the protein binding moiety of the molecule. Chimeric small molecules that induce phosphorylation can be optionally provided with adenosine monophosphate (AMP) or another molecule providing an additional phosphate group. Without being bound by theory, the addition of the AMP or other phosphate providing molecule can enhance phosphorylation.
[0552] In an example embodiment, inhibition of nucleotide-binding proteins may comprise inhibition binding of a CRISPR-Cas protein to a nucleic acid or transcription factors binding to DNA. Thus, proteins that have been modified to comprise a binding domain that can be targeted by an orthogonal tag, e.g., Cas9 comprising a FKBP binding domain, can be inhibited by the use of small molecules comprising an orthogonal tag, such as a dTAG. Sequence specific modular adaptors consisting of a DNA-binding protein and a self-ligating protein tag can be utilized. See, e.g., Nguyen et al., Rational design of a DNA sequence-specific modular protein tag by tuning the alkylation kinetics, Chem Sci., 40 (2019) doi: 10.1039/C9SC02990G. Similarly, nucleotide binding may be modified via the modification of transcription factors with the chimeric small molecules. Because post-translation phosphorylation of transcription factors might be necessary for direct binding interactions or a conformational change in a transcription factor, thereby leading to, activating, or inhibiting gene transcription, methods of modification of transcription factors are provided. In an example embodiment, methods of use can comprise eliciting an immune reaction, creation of an autoantigen, and target deactivation. In an exemplary embodiment, hyper- phosphorylation or neo-phosphorylation of a target protein may result in immune recruitment to a target, for example via trigger display of neo-eptiopes and T-cell attack on cells displaying the epitopes. In one application, the small molecules disclosed herein are utilized in human leukocyte antigen (HLA) display and immune response. Neo-phosphorylation to elicit an immune response can find use in cancer immunotherapy approaches. In an exemplary approach, a kinase is selected for the phosphorylation of p53, for example, at Ser33, Ser315 and/or Thr82. This phosphorylation leads to subsequent binding and conformational changes which leads to activation as a transcription factor. See, e.g., Ryan and Vousden, Nature, 419 (2002). Thus, design of a molecule comprising a binding moiety for an kinase that phosphorylates or dephosphorylates along with a target for p53 can allow control of nucleotide binding based on desired conformation of the transcription factor. See also, e.g., Mattiske T, Tan MH, Dearsley O, Cloosterman D, Hii CS, Geez J, et al. (2018) Regulating transcriptional activity by phosphorylation: A new mechanism for the ARX homeodomain transcription factor. PLoS ONE 13(11): e0206914.
Doi: 10.1371/journal. pone.0206914. Kinasopathies
[0553] Treatment of kinasopathies is also contemplated, see, generally, Lahiry et al., Nature Reviews Genetics, 2011, with Table 1 disclosure of inherited kinasopathies incorporated herein by reference. Accordingly, for kinasopathies that have a loss of function, a chimeric small molecule according to the invention can recruit a working kinase to provide the lost function. See, e.g., Lahiry et. al, Nature Reviews Genetics volume 11, pages60-74 (2010)(discussing various germline disorders and cancers related to kinase dysfunction), incorporated herein by reference, in particular Supplementary Table 1 of inhereited kinasopathies and Supplementary Table 2 of kinases associated with cancer. In an exemplary embodiment, Src family protein tyrosine kinases (SFKs) are stabilized in active conformation by phosphorylation of a conserved YA in the active A-loop conformation. By targeting an SFK for modification, e.g., phosphorylation at the A-loop, treatment of aberrant SFK can address kinasopathies associated with the SFK, e g., ALL, CML. See, e.g., Mechanism of Drug-Resistance in Kinases, Expert Opin Investig Drugs. 2011 Feb; 20(2): 153-208; doi: 10.1517/13543784.2011.546344.
Regulated Induced Proximity Targeting Chimeras (RIPTACs)
[0554] In an example embodiment, the functional moieties of a RIPTAC are used as a target binding moiety and kinase binding moiety of the chimeric small molecules as described herein. A RIPTAC is a bifunctional molecule comprising of a moiety targeting a protein of interest and a moiety capable of binding to pan-expressed protein essential for cell survival. For example, a RIPTAC may comprise binding moieties directed to two disease-specific proteins (e.g., cancer- specific proteins). After binding the two disease specific proteins, their proximity to each other, anchored by the RIPTAC, forces them to interfere with each other’s functions See e.g., Raina, K. et al. Regulated Induced Proximity Targeting Chimeras (RIPTACs): A Novel Heterobifunctional Small Molecule Therapeutic Strategy for Killing Cancer Cells Selectively, 2023; Liu, J. O. Targeting Cancer with Molecular Glues. Science, 2023, 381, 729-730; Schulze, C. J.; et al. Chemical Remodeling of a Cellular Chaperone to Target the Active State of Mutant KRAS. Science, 2023, 381, 794-799, each of which are hereby incorporated by reference. An example of a chimeric small molecule connecting the two moieties of a RIPTAC can be understood through Figure 2 of Raina et al. Figure 2 highlights the linkers connecting various RIPTACs. One of ordinary skill in the art could substitute the linkers described in Raina et al. with the linkers and electrophilic reactive groups described herein using known methods in the art to achieve the chimeric small molecule. Raina et al. demonstrates varying linker composition and length can be advantageously altered to adjust the degree of selectivity.
[0555] Accordingly, a RIPTAC could be modified to include the binding moieties, linkers, and/or electrophilic reactive groups as described herein without inhibiting its function. In example embodiments, a chimeric small molecule described herein may comprise a kinase binding moiety directed to an over-expressed kinase and a target binding moiety directed to a protein with abnormal function. In an example embodiment, a chimeric small molecule described herein is used as a RIPTAC.
Methods of Use with Kinase Inhibitor Bindins Moiety
[0556] In one example embodiment, the method comprises generating a reprogrammed cellular kinase by delivering a chimeric small molecule of the formula A-Li-E-B or A-L1-E-L2- B, wherein A is an protein binding moiety specific for the cellular protein to be repurposed/ reprogrammed; B is a target binding moiety specific for the target substrate to be modified; Li and L2 is a linker; and E is an electrophilic reactive group whereby the chimeric small molecule labels the cellular protein with the target binding moiety for the target substrate; and modifying the target substrate by binding of the repurposed/reprogrammed protein to the target substrate via the target binding moiety, whereby the repurposed/reprogrammed cellular protein introduces one or more modifications to the target substrate. In one example embodiment, the protein binding moiety has a half-life about 2, 3, 4, 5, 6 or 7 times less than a half-life of the protein to be repurposed/reprogrammed. In one example embodiment, the protein to be reprogrammed is an oxidoreductase, transferase, hydrolase, lyase, isomerase, ligase, or translocase. In one example embodiment, an inhibitor is a protein binding moiety. In one example embodiment, the protein to be repurposed/reprogrammed is a kinase and the protein binding moiety is a kinase inhibitor. In one example embodiment, the kinase inhibitor is a ‘promiscuous’ kinase inhibitor. In one example embodiment, the method comprises administering a coupling molecule thereby quenching the inhibitory activity of the protein inhibitor. In one example embodiment, the coupling molecule is one or more of an aldehyde, alkene, alkyne, strained alkyne, cyclooctyne, trans-cyclooctene, cyclopropene, oxanorbomadiene, norbornene, phosphine, electron-rich dienophile, isonitrile, isocyanopropanoate, tetrazole, 2-acylboronic acid, or any derivative thereof. In one example embodiment, the cyclooctyne derivative comprises dibenzocyclooctyne, biarylazacyclooctynone, or dimethoxyazacyclooctyne. In one example embodiment, the method comprises a strained alkyne comprising a bicyclononyne or dioxabiaryldecyne.
[0557] In one example embodiment, the method comprises a chimeric small molecule wherein the protein binding moiety has a half-life about 2, 3, 4, 5, or 6 times less than a half-life of the protein to be reprogrammed. In an example embodiment, the protein to be reprogrammed is an oxidoreductase, transferase, hydrolase, lyase, isomerase, ligase, or translocase. In an example embodiment, the kinase binding moiety is an inhibitor. In an example embodiment, the protein to be reprogrammed is a kinase and the kinase binding moiety is a kinase inhibitor. In an example the kinases inhibitor is a promiscuous kinase inhibitor.
[0558] In one example embodiment, the method comprises a chimeric small molecule wherein the kinase binding moiety contains a bio-orthogonal group capable of reacting with and bonding to a coupling molecule. In an example embodiment, the method further comprises administering a coupling molecule. The coupling small molecule is administered to react with the bio-orthogonal group on the chimeric small molecule and, as a result, quench the kinase inhibitor from binding to the kinase. In an example embodiment, the coupling molecule is one or more of an aldehyde, alkene, alkyne, strained alkyne, cyclooctyne, trans-cyclooctene, cyclopropene, oxanorbornadiene, norbomene, phosphine, electron-rich dienophile, isonitrile, isocyanopropanoate, tetrazole, 2- acylboronic acid, or any derivative thereof. In an example embodiment, the cyclooctyne derivative comprises dibenzocyclooctyne, biarylazacyclooctynone, or dimethoxyazacyclooctyne. In one example embodiment, the strained alkyne comprises bicyclononyne or dioxabiaryldecyne.
[0559] In one example embodiment, the coupling molecule is co-administered with the chimeric small molecule. In an example embodiment, the coupling molecule is administered after the administration of the chimeric small molecule. In an example embodiment, the coupling molecule is administered within 24 hours, or within 12 hours, or within 11 hours, or within 10 hours, or within 9 hours, or within 8 hours, or within 7 hours, or within 6 hours, or within 5 hours, or within 4 hours, or within 3 hours, or within 2 hours, or within 1 hour, or within 30 minutes or less of administering the chimeric small molecule. Delivery of Coupling Molecules
[0560] In one aspect, the method comprises an additional step of administering or delivering a coupling molecule. The coupling molecule, as previously described, reacts with a bio-orthogonal group on the protein targeting moiety. This reaction suppresses binding of the binding moiety to the protein. When utilized with a chimeric small molecule comprising an electrophilic reactive group, the protein binding moiety may be released from the chimeric small molecule, and the coupling molecule may bind to the biorthogonal group of the kinase binding moiety, thereby preventing the kinase binding moiety from further binding the kinase. In one example embodiment, the coupling molecule is utilized with a kinase binding moiety that is an inhibitor of the protein. [0561] The coupling molecule may be administered in any pharmaceutical formulation, effective amount, and dosage form previously described. The coupling molecule may be delivered using any previously described method or administered with any co-therapies or combinations and as described herein. The chimeric small molecule and the coupling molecule may by delivered or administered concurrently or sequentially. The concurrent delivery of the coupling molecule and chimeric small molecule may occur within the same delivery method or with a separate delivery method. The concurrent but separate delivery of the coupling small molecule may be the same type of delivery method, or a different type of delivery method previously described. Sequential delivery of the coupling molecule may occur with the same type of delivery method or different type of delivery method. Sequential delivery of the coupling molecule may occur within 24 hours, or within 12 hours, or within 11 hours, or within 10 hours, or within 9 hours, or within 8 hours, or within 7 hours, or within 6 hours, or within 5 hours, or within 4 hours, or within 3 hours, or within 2 hours, or within 1 hour, or within 30 minutes or less of administering the chimeric small molecule.
Coupling Molecules
[0562] In one preferred embodiment, a coupling molecule is introduced to a system containing the chimeric small molecule. As the coupling molecule comes into contact with the chimeric small molecule bound to the target protein, it quenches the binding between the protein binding moiety and target protein. In one example embodiment, the coupling molecule is a molecule capable of undergoing a reaction with a biorthogonal molecule, which is a substituent of the protein binding moiety. The reaction results in the coupling molecule attaching to the protein binding moiety and, as a result, the protein binding moiety no longer binds to the protein. In one example embodiment, the coupling molecule can react with the bio-orthogonal moiety through an aldehyde/ketone- nucleophile reaction, dipolar cycloaddition, phosphine ligation, Diels- Alder cycloaddition, [4+1] cycloaddition, nitrile imine-alkene reaction, or 2-acylboronic acid condensation, or any other bio- orthogonal reaction.
[0563] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a aldehyde/ketone-nucleophile condensation. Classily, an aldehyde couples with an amine group such as alkoxyamine or hydrazine, for example. While intracellular metabolites contain aldehydes and ketones, this approach is effective on the cell surface. In one preferred embodiment, the coupling molecule is an aldehyde.
[0564] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a dipolar cycloaddition. Dipolar cycloadditions typically occur between azides and alkynes and either in the presence or absence of copper. In the case of copper free dipolar cycloadditions, the alkyne is strained to facilitate the reaction. In most cases, the strained alkyne is cyclooctyne or any derivative thereof. Non-limiting examples of cyclooctynes include: dibenzocyclooctyne, biarylazacyclooctynone, and dimethoxyazacyclooctyne. In one example embodiment, the coupling molecule is an alkyne. In an example embodiment the coupling molecule is a strained alkyne. In one preferred embodiment, the coupling molecule is cyclooctyne. While it is understood any strained alkyne may be used other non-limiting examples include bicyclononyne, dioxabiaryldecyne, and any derivative thereof.
[0565] The dipolar cycloaddition may also comprise a reaction between oxanorb ornadiene and an azide. In this case, after the cycloaddition between the oxanorb ornadiene and azide, a spontaneous retro-Diels Alder reaction occurs generating a triazole and furan. In one example embodiment the coupling molecule is oxanorb ornadiene or any derivative thereof.
[0566] The dipolar cycloaddition may also comprise the reaction between norbornene and a nitrile oxide. In one example embodiment, the coupling molecule is norbomene. The coupling molecule may also perform a dipolar cycloaddition with another dipolar molecule such as a nitrone, (imino)syndone, or l,3-dithiolium-4-olate and would comprise of the counterpart unsaturated hydrocarbon. [0567] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a phosphine ligation, or interchangeably referred to as the Staudinger ligation. A phosphine ligation typically occurs between an azide and phosphine typically forming a phosphine oxide and a stable amide linkage or, when electron deficient aromatic azides are used, forming an iminophosphorane. In one example embodiment, the coupling molecule is a phosphine or any derivative thereof. Phosphine ligations may also comprise a cyclopropene in place of the azide. Non-limiting examples of cyclopropane include: cyclopropenones, cyclopropenethiones, cyclopropenium ions.
[0568] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a Diels- Alder cycloaddition. The reaction is an inverse electron-demand Diels- Alder and classically occurs between an electron-poor diene and an electron-rich dienophile. In one example embodiment, the coupling molecule is an electron-rich dienophile. The Diels- Alder cycloaddition may comprise a tetrazine ligation wherein a strained unsaturated hydrocarbon and a tetrazine or triazene couple to form a pyridazine. In one example embodiment, the coupling molecule is a strained unsaturated hydrocarbon. The unsaturated hydrocarbon may also be cyclic. Non-limiting example of strained, cyclic unsaturated hydrocarbons include cyclooctynes, trans-cyclooctenes, norbomenes, cyclopropenes, and azetines. In preferred embodiments, the coupling molecule is a cyclooctyne, trans-cyclooctene, or a derivative thereof.
[0569] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a [4+1] cycloaddition. The reaction involves the coupling of an isonitrile with, classically, a tetrazine followed by a spontaneous retro-Diels Alder elimination. The conjugate of the reaction is more stable if the isonitrile is tertiary. However, less stable conjugates are formed when the isonitrile is primary or secondary. In one preferred embodiment, the coupling molecule is an isonitrile or any derivative thereof. In one example embodiment, the isonitrile is tertiary. In one preferred embodiment, the coupling molecule is isocyanopropanoate or any derivative thereof.
[0570] In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a nitrile imine-alkene cycloaddition. Classically, tetrazole is photolyzed to generate nitrile imine which readily couple with unsaturated hydrocarbons. The wavelength necessary for photolysis is dependent on the substituents of tetrazine. However, photolysis is not required if hydrazonoyl chlorides are present, which, at neutral pH, spontaneously generate nitrile imines from tetrazole. In one preferred embodiment the coupling molecule is an unsaturated hydrocarbon and is optionally introduced with a hydrazonoyl chloride.
In one example embodiment, the coupling molecule and bio-orthogonal moiety couple through a 2-acylboronic acid condensation. In this reaction, the boronic acid couples with an amine to form a stable diazaborine. In one preferred embodiment, the coupling molecule is 2-acylboronic acid or any derivative thereof.

Oncogenic Applications
[0571] In one example embodiment, the disease is associated with cancer. In particular, the disease is oncogenic. Many oncogenic targets are known and can be regulated by posttranslational modifications. See, e g., Chen, L., Liu, S. & Tao, Y. Regulating tumor suppressor genes: post- translational modifications. Sig Transduct Target Ther 5, 90 (2020); doi: 10.1038/s41392-020- 0196-9. Exemplary post-translational modification types of proteins implicated in oncogenesis and their expression pattern are found in Table 1 of Sharma, et al., (2019). Post-Translational Modifications (PTMs), from a Cancer Perspective: An Overview. Oncogen 2(3): 12, specifically incorporated herein by reference.
[0572] The chimeric small molecules disclosed herein can be utilized in methods of treating cancer. Methods of treating cancer can include generating a repurposed/reprogrammed cellular protein by administering a chimeric small molecule, as described herein. The chimeric small molecule labels the cellular protein with an oncogenic target kinase binding moiety via the electrophilic reactive group moiety. The electrophilic reactive group reacts with and bonds to a nucleophilic side chain on the cellular protein. Labelling of the cellular protein can allow for bonding to, or association with, the oncogenic target protein, or to a molecule in proximity to the oncogenic protein facilitating modification of the target substrate. In one aspect, the methods comprise inducing phosphorylation of the oncogenic target protein in or on the cell. The methods may comprise contacting the oncogenic target protein with the chimeric small molecule. In one example embodiment, the oncogenic target protein is in proximity to a kinase specific to the protein binding moiety of the molecule. Chimeric small molecules that induce phosphorylation can be optionally provided with adenosine monophosphate (AMP) or another molecule providing an additional phosphate group. Without being bound by theory, the addition of the AMP or other phosphate providing molecule can enhance phosphorylation.
[0573] Methods of treating cancer are provided. The method of treating cancer comprises generating a reprogrammed cellular protein by administering to a subject in need thereof a chimeric small molecule of the formula: A-Li-E-B or A-L1-E-L2-B, wherein A is an protein binding moiety; E is an electrophilic reactive group and B is an oncogenic target protein to be modified, whereby the chimeric small molecule labels the cellular protein with the target binding moiety for the target substrate; and modifying the oncogenic target protein by binding of the repurposed/reprogrammed protein to the target substrate via the target binding moiety, whereby the repurposed/reprogrammed cellular protein introduces one or more modifications to the target substrate. In one example embodiment, the target binding moiety is specific for KRAS, RAS, FKPB12F36V, EGFR, HSP90, BTK, MDM2, BRIM, BCR-ABL, NF-kB, LDH-A, p53, GP73, MUC1, MUC16, CD44, GPCR, HMGB1, RI0K1, CHK1, UBE2F, HuR, PTEN, STAT-3, Osteopontin, EGFRs, AKT, DAPK1, Rho, Ubc9, FOXK2, HIC1, HER2, BRAF, BCL-2, CD117, (KIT), ALK, PI3K, Delta, DNMT1, or SMO. In one example embodiment, the cellular protein to be reprogrammed is an oxidoreductase, transferase, hydrolase, lyase, isomerase, ligase, translocase. In one example embodiment, the kinase binding moiety is a kinase inhibitor. In one example embodiment, the kinase inhibitor is specific for PK, PKC, AMPK, MAPK, EGFR, FGFR, NGFR, TrkA, ABL, BCKDK, CDK, PI3K, VEGFR, BRAF, MEK, AKT, ALK, BTK, FLT3, JAK2, AURKA, c-MET, DDR, FKBP, INSR, IKK, JNK, mTOR, PAK, PDK1, PDK2, PTK2/FAK, pyruvate kinases, RAC- a, RIPK, TYK2, SHP, aPKC, NOP, p opioid receptor, 5 opioid receptor, UMPK, SphK, or GSK- 3. In one example embodiment, administering a coupling molecule thereby quenching the inhibitory activity of the kinase inhibitor.
[0574] Methods of treating a disease associated with aberrant KRAS signaling is provided, comprising administering a composition comprising a chimeric small molecule, the chimeric small molecule comprising the KRAS binding molecule and a kinase binding molecule of as described herein. In one example embodiment, the kinase binding molecule is a target for an kinase selected from the group consisting of: PK, PKC, AMPK, MAPK, EGFR, FGFR, NGFR, TrkA, ABL, BCKDK, CDK, PI3K, VEGFR, BRAF, MEK, AKT, ALK, BTK, FLT3, JAK2, AURKA, c-MET, DDR, FKBP, INSR, IKK, JNK, mTOR, PAK, PDK1, PDK2, PTK2/FAK, pyruvate kinases, RAC- oc, RIPK, TYK2, SHP, aPKC, NOP, p opioid receptor, 5 opioid receptor, UMPK, SphK, or GSK- 3. In an embodiment, the kinase binding molecule is an AMPK binding moiety. In one example embodiment, the KRAS is KRASG12C. In one example embodiment, the chimeric small molecule phosphorylates one or more residues on KRAS selected from the group consisting of Seri 7, Ser39, Ser65, Serl06, Serl22, Serl36, Ser2, Thr2, Thr35, Thr50, Thr74, Thr87, Thrl24, Thrl27, Thrl48. [0575] In an example embodiment, a method of treating cancer in a cell is provided, comprising administering a chimeric small molecule of the present invention. In one example the small molecule comprises a P13K kinase binder, a linker, an electrophilic reactive group, and a p53 target binding moiety, e.g., based on idasanutlin. In one example embodiment, the molecule comprises a binder of P13K based on the inhibitor PIK108 that further optionally comprises bioorthogonal group, e.g., cyclopropenyl. The binding moiety PIK108 comprises a linker connected to the electrophilic reactive group, e.g., dibromophenyl benzoate. The electrophilic reactive group, in turn, is connected to the p53 protein target binding moiety, optionally via a linker. Upon binding to the PI3K kinase via PIK108, proximal lysines of the binding pocket of PI3K, and will react with the lysine-reactive group (e.g., dibromophenyl benzoate) and expel the kinase inhibitor, leaving the P13K tagged with the p53 binder. The kinase which is covalently labeled with the target binding moiety can then hyper and/or neo-phosphorylate the p53. Administration of a tetrazine coupling molecule can quench the cyclopropenyl biorthogonal group when displayed on the PI3K binding molecule and deactivate the expelled kinase binding moiety. [0576] Exemplary oncogenic fusion proteins that can be treated by the binding of a multimeric kinase include fusions associated with the ABL proteins. ABL proteins are non-receptor tyrosine kinases that are normally under well-orchestrated regulation. However, chromosome translocations that join the ABL genes with genes coding for other proteins give rise to various oncogenic fusion proteins (BCR-ABL, TEL-ABL, NUP214-ABL, etc.) that are prone to dimerization (or oligomerization) and subsequent autophosphorylation. Consequently, ABL kinase becomes constitutively active and lead to diseases such has chronic myeloid leukemia (CML), acute lymphocytic leukemia (ALL) and other myeloproliferative disorders. An example oncogenic fusion is BCR-ABL. This may be particularly true for kinases such as Abl which must form complexes to become active. [0577] In example embodiments, the cancer is characterized by an oncofusion of a kinase, e.g., ABL-kinase. Oncogenic ABL fusion proteins are known in the art and implicated in a variety of proliferative disorders. Chromosome translocations occur joining the genes of ABL with genes coding for other proteins, giving rise to various proteins that are prone to dimerization (or oligomerization) and autophosphorylation, making the ABL kinase constitutively active and leading to myeloproliferative disorders. In example embodiments, the oncofusion is TEL- ABL or NUP214-ABL.
[0578] Translocation events in cancer have been shown to be associated with fusions involving ALK, BRAF, EGFR, FGFR1, 2 and 3, NTRK1, 2 and 3, PDGFRA, PRKCA and B, RAFI, RET, ROS1, FGR, MET, PIK3CA, and PKN1.

In particular, druggable kinases that engage in fusions include AKT3, ALK, BRAF, BRD4, CD74, EGFR, EML4, ERBB4, ESRI, FGFR2, FGFR3, JAK2, MET, NOTCH1, NRG1, NTRK1, NTRK3, NUP214-ABL1, PDGFRA, PDGFRB, PML-RARA, RAFI, RET, ROS1, TMPRSS2, and TRIM33-RET have also been identified.

[0580] Example targetable fusions include ALK fusions, such as TFG-ALK. ALK fusions have been identified in multiple cancer types, for example lung adenocarcinoma, bladder, colorectal, breast, renal cell, renal medullary and thyroid cancers. In particular, EML4-ALK fusions were found in lung adenocarcinoma, STRN-ALK fusion in thyroid cancer and in papillary renal carcinoma, TPM1-ALK fusion in bladder cancer, SMEK2-ALK fusion in rectal adenocarcinoma and GTF2IRD1-ALK fusion in thyroid cancer.

In particular, TRIM-BRAF fusion has been found in rectal adenocarcinoma, ATG7-BRAF in melanoma, and ZC3HAV1-BRAF as well as FAM1 14A2-BRAF in thyroid cancer. Other example fusions include AGK-BRAF, SND1-BRAF, MACF1-BRAF, TAXI BP 1 -BRAF and CDC27-BRAF. It is known in the art BRAF dimers are not sensitive to RAF inhibitors and instead be treated to inhibition downstream through, for example, MEK inhibition. [0581] Another targetable fusion includes FGFR fusions, which have been identified in glioblastoma multiforme, bladder urothelial carcinoma, lung squamous cell carcinoma, kidney papillary cell carcinoma, brain low-grade glioma, prostate adenocarcinoma, head and neck squamous cell carcinoma, breast invasive carcinoma, stomach adenocarcinoma tumor types.

Another notable fusion is TPR-MET.
[0582] Another targetable fusion includes NTRK fusions, which have been associated with congenital fibrosarcoma, human secretory breast carcinoma, and papillary thyroid cancer, including glioblastoma, cholangiocarcinoma and pediatric high-grade glioma. In particular, PAN3-NTRK2 have been found in head and neck squamous cell carcinoma, AFAP1-NTRK2 low-grade glioma, TRIM24-NTRK2 in lung adenocarcinoma, and TPM3-NTRK1 in sarcoma and thyroid cancer. Another targetable fusion includes PIK3CA fusions, which have been found in endometrial cancers, breast invasive carcinomas, and colorectal, head, and neck cancers. In particular, TBL1XR1-PIK3CA fusions have been found in breast cancer and prostate adenocarcinoma, FNDC3B-PIK3CA fusion in uterine corpus endometrial carcinoma, and TBL1XR1-PIK3CA fusions in invasive breast carcinoma and prostate cancer. Another targetable fusion is PKC fusions, which have been found in papillary glioneuronal tumors and benign fibrous histiocytoma.

Another notable ROS1 fusion is CD74-ROS1 while other fusions have been found in 8/513 lung adennocarcinomas.
[0584] Tyrosine kinase fusion genes are a notable class of oncogenes. Tyrosine kinase fusions have been found in leukemia and solid tumors. Like other fusions, they are created by translocations and other chromosomal rearrangements of a subset of tyrosine kinase genes. These fusions include ABL, PDGFRA, PDGFRB, FGFR1, SYK, RET, JAK2 and ALK. The kinase domain is activated by enforced oligomerization and inactivation of inhibitory domains. Activated tyrosine kinase fusions then signal via an array of transduction cascades. The fusion partner recruits proteins that contribute to signaling, protein stability, cellular localization and oligomerization.

[0586] Gao et al. provides a table of potentially druggable fusion events and their targets in Table S5, specifically incorporated herein by reference for its teaching of fusions, targets and indications associated with the fusion events.
[0587] Exemplary cancers associated with such fusions include adrenocortical carcinoma, bladder urothelial carcinoma, brain lower grade glioma, breast invasive carcinoma, cervical squamous cell carcinoma and endocervical adenocarcinoma, cholangiocarcinoma, colon adenocarcinoma, esophageal carcinoma, glioblastoma multiforme, head and neck squamous cell carcinoma, kidney chromophobe, kidney renal clear cell carcinoma, kidney renal papillary cell carcinoma, acute myeloid leukemia, liver hepatocellular carcinoma , lung adenocarcinoma, lung squamous cell carcinoma, lymphoid neoplasm diffuse large B cell lymphoma, mesothelioma, ovarian serous cystadenocarcinoma, pancreatic adenocarcinoma, pheochromocytoma and paraganglioma, prostate adenocarcinoma, rectum adenocarcinoma, sarcoma, skin cutaneous melanoma, stomach adenocarcinoma, testicular germ cell tumors, thymoma, thyroid carcinoma, uterine carcinosarcoma, uterine corpus endometrial carcinoma, and uveal melanoma.
[0588] Isoforms of RAS have conserved amino acid sequences in the Swtich-I and Switch-II regions of Ras. The Switch regions of Ras are the binding interface for effector proteins and Ras regulators such as GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs). Several cancer mutations are located within Switch II, and the P-loop attached to Switch- I. Thus, phosphorylation of loop residues in the Switch-I or Switch-II may address Ras activity, as post-translation modifications of loop residues are known generally to generate conformational changes.
[0589] KRAS is a key regulator of cell proliferation, differentiation and survival, and is the most frequently mutated oncogene in human cancers. An exemplary oncogenic driver mutation is KRASG12C. The active GTP -bound state of KRAS is a closed conformation, while the inactive, GDP -bound states is an open conformation. In KRAS G12C, and other oncogenic RAS mutations, a dysregulated excess of cellular GTP -bound RAS results, with the RAS function remaining in the open conformation active state that results in uncontrolled cell growth and proliferation, invasiveness and evasion of immune surveillance. Accordingly, inhibition of GTPases (e.g., Ras) is within the scope of the chimeric small molecules disclosed herein.
[0590] Without being bound by a particular scientific theory, it is proposed phosphorylation of KRAS, particularly KRASG12C may facilitate generation of conformational change, perhaps by disrupting binding to GTPase-activating proteins, thereby decreasing Ras activity which is implicated in oncogenesis. For example, phosphorylation of T35 or S17 residues which coordinate to Mg2- ion that also coordinates to the gamma- and beta-phosphates of GTP can potentially disrupt the 4-way Mg2+ chelation. This tetra-chelated Mg2+ state is characteristic of the active GTP-bound state “closed conformation” while inactive GDP-bound state only has SI 7 and the gamma-phosphate of GDP involved in Mg2+ binding. Further without being bound by theory, it may be that phosphorylation of any Switch-I or Switch-II or Switch-adjacent residues can disrupt protein-protein interactions between the Switch regions and Ras regulators, and the activating proteins, or that phosphorylation of loop residues in Switch-I or Switch II can cause conformation changes, as post-translational modifications of loop residues are often known to generate conformational changes. Accordingly, modulating KRAS signaling with a kinase utilizing the phosphorylation inducing chimeric small molecules described herein may be useful as an anti- cancer therapy by disrupting KRAS membrane localization or binding partners.

One such protein is in the bromodomain family of proteins. Bromodomains are a family of (-110 amino acid) structurally and evolutionary conserved protein interaction modules that specifically recognize acetylated lysines present in substrate proteins, notably histones. Bromodomains exist as components of large multidomain nuclear proteins that are associated with chromatin remodeling, cell signaling and transcriptional control. Examples of bromodomain-containing proteins with known functions include: (i) histone acetyltransferases (HATs), including CREBBP, GCN5, PCAF and TAFII250; (ii) methyltransferases such as ASH IL and MLL; (iii) components of chromatin-remodeling complexes such as Swi2/Snf2; and (iv) a number of transcriptional regulators (Florence et al. Front. Biosci. 2001, 6, D1008-1018, hereby incorporated by reference in its entirety.).
[0619] Bromodomain mediated or BET-mediated such as BRD2-mediated, BRD3 -mediated, BRD4-mediated, and/or BRDT-mediated disorders or conditions may be any disease or other deleterious condition in which one or more of the bromodomain-containing proteins, such as BET proteins including BRD2, BRD3, BRD4 and/or BRDT, or a mutant thereof, are known to play a role. Accordingly, another embodiment of the present disclosure relates to treating or lessening the severity of one or more diseases in which one or more of the bromodomain-containing proteins, such as BET proteins, such as BRD2, BRD3, BRD4, and/or BRDT, or a mutant thereof, are known to play a role. For example, a disease or condition in which the biological function of bromodomain affects the development and/or course of the disease or condition, and/or in which modulation of bromodomain alters the development, course, and/or symptoms. Bromodomain mediated disease or condition includes a disease or condition for which bromodomain inhibition provides a therapeutic benefit, e.g., wherein treatment with bromodomain inhibitors, including compounds described herein, provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition. Compounds for inhibiting bromodomains or bromodomain inhibitors are typically compounds which inhibit the binding of a bromodomain with its cognate acetylated proteins, for example, the bromodomain inhibitor is a compound which inhibits the binding of a bromodomain to acetylated lysine residues.

Methods for the treatment of a disease, disorder, or condition in a subject in need thereof can comprise administering a molecule disclosed herein to a subject.
Pathogenic Applications
[0621] The chimeric small molecules disclosed herein can be utilized in methods of treating infection by a pathogen. Methods of treating infection by a pathogen can include generating a repurposed/reprogrammed cellular protein by administering a chimeric small molecule, as described herein. The chimeric small molecule labels the cellular kinase with a pathogenic target binding moiety via the electrophilic reactive group moiety. The electrophilic reactive group reacts with and bonds to a nucleophilic side chain on the cellular kinase. Labelling of the cellular kinase can allow for bonding to, or association with, the pathogenic target protein via the target binding moiety, or to a molecule in proximity to the pathogenic target protein, thereby facilitating modification of the target substrate. In one aspect, the methods comprise inducing phosphorylation of the target substrate, i.e., pathogenic protein, in or on the cell. The methods may comprise contacting the pathogenic protein with the chimeric small molecule. In one example embodiment, the pathogenic protein is in proximity to a kinase specific to the kinase binding moiety of the molecule. Chimeric small molecules that induce phosphorylation can be optionally provided with adenosine monophosphate (AMP) or another molecule providing an additional phosphate group. Without being bound by theory, the addition of the AMP or other phosphate providing molecule can enhance phosphorylation.
[0622] Methods for treating infection by a pathogen are provided. The method comprises, generating a reprogrammed cellular protein by administering to a subject in need thereof a chimeric small molecule of the formula: A-Li-E-B or A-L1-E-L2-B, wherein A is an protein binding moiety; Li and L2 is a linker; E is an electrophilic reactive group and B is a pathogen protein to be modified, whereby the chimeric small molecule labels the cellular protein with the target binding moiety for the target substrate; and modifying the pathogen protein by binding of the repurposed/reprogrammed protein to the pathogen protein via the target binding moiety, whereby the repurposed/reprogrammed cellular protein introduces one or more modifications to the target substrate. In one example embodiment, the cellular protein to be reprogrammed is a oxidoreductase, transferase, hydrolase, lyase, isomerase, ligase, translocase. In one example embodiment, the pathogen is a viruses, bacteria, fungi, or protozoa. In one example embodiment, the bacteria is Mycobacterium tuberculosis (Mtb) or Pseudomonas aeruginosa (PsA). In one example embodiment, the pathogen is Mtb and the pathogen protein is one or more of PtpA, PtpB, SapM, ESAT-6, and Rv2966c. In one example embodiment, the pathogen is (PsA) and the target binding moiety is Colistin. In one example embodiment, the kinase binding moiety is a kinase inhibitor. In one example embodiment, the kinase inhibitor is a promiscuous inhibitor. In one example embodiment, a step of administering a coupling molecule thereby quenching the inhibitor activity of the kinase inhibitor is provided.
[0623] A pathogen may include viruses, bacteria, fungi, and protozoa. In one example embodiment, the pathogen is a pathogenic bacteria and may include: spirochetes; spirilla; vibrios; gram-negative aerobic rods and cocci; enterics; pyogenic cocci; and endospore-forming bacteria; actinomycetes and related bacteria; rickettsias and chlamydiae; mycoplasmas, which are groups defined by some bacteriological criteria. A pathogenic bacteria may include: Escherichia coli, Salmonella enterica, Salmonella typhi, Shigella dysenteriae, Yersina pestis, Pseudomonas aeruginosa, Vibrio cholerae, Bordetella pertussis, Haemophilus influenza, Helicobacter pylori, Campylobacter jejuni, Neisseria gonorrhoeae, Neisseria meningitidis, Brucella abortus, Bacteroides fragilis, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Bacillus anthracis, Bacillus cereus, Clostridium tetani, Clostridium perfringens, Clostridium botulinum, Clostridium difficile, Corynebacterium diphtheriae, Listeria monocytogenes, Mycobacterium tuberculosis, Mycobacterium leprae, Chlamydia trachomatis, Chlamydia pneumoniae, Mycoplasma pneumoniae, Rickettisas, Treponema pallidum, Borrelia burgdorferi , or a variant thereof. (Todar, K. Textbook of Bacteriology (2020) Online).
[0624] A target virus may belong to any morphological category including helical, envelope, or icosahedral. A target virus may comprise of DNA or RNA, may be single stranded or double stranded, and may be linear or circular. The genome of the virus may be one nucleic acid molecule or several nucleic acid segments. A target virus may belong to the family: Adenoviridae, Papovaviridae, Parvoviridae, Herpesviridae, Poxviridae, Anelloviridae, Pleolipoviridae, Reoviridae, Picornaviridae, Caliciviridae, Togaviridae, Arenaviridae, Flaviviridae, Orthomyxoviridae, Paramyxoviridae, Bunyaviridae, Rhabdoviridae, Filoviridae, Astroviridae, Bornaviridae, Arteriviridae, Hepeviridae, Retroviridae, Caulimoviridae, Hepadnaviridae, Coronaviridae. In one example embodiment, the virus is SARS-CoV-2.(Gelderblom HR. Structure and Classification of Viruses. In: Baron S, editor. Medical Microbiology. 4th edition. Galveston (TX): University of Texas Medical Branch at Galveston; 1996. Chapter 41).
[0625] In an exemplary embodiment, the pathogen is a pathogenic fungi and may include: Aspergillus; Blastomyces; Candida; Coccidioides; Cryptococcus; Fusarium; Microsporum; Epidermophyton; Trichophyton; Histoplasma; Rhizopus; Mucor; Rhizomucor; Syncephalastrum; Cunninghamella; Apophysomyces; Lichtheimia (formerly Absidia); Eumycetoma; Pneumocystis; Trichophyton; Microsporum; Epidermophyton; Sporothrix; Paracoccidioides; Talaromyces or a variant or species thereof. (CDC)
[0626] In an exemplary embodiment, the pathogen is a pathogenic protozoa belonging to the group: Sarcodina; Mastigophora; Ciliophora; or Sporozoa defined by their mode of movement. (CDC) In one example embodiment, the pathogenic protozoa may include: Entamoeba; Trichomonas; Leishmania; Chilomonas; Giardia; Isopora; Sarcocystis; Nosema; Balantidium; Eimeria; Histomonas; Trypanosoma; Plasmodium; Babesia; or Haemoproteus or a variant or species thereof.
[0627] In one aspect, the method comprises treating infection by a pathogen as a result of M. tb. In an example embodiment, the pathogenic target is Mycobacterium tuberculosis (M. tb). Successful infection of host macrophages by M. tb hinges on the weakening of the diverse microbicidal responses by the host cell. M. tb furthers infection by impeding the host cellular signaling machinery. Therefore, infection can be inhibited by phosphorylating proteins associated with M. tb, which promotes increased signaling to the immune system. In one example embodiment, the chimeric small molecule target binding moiety targets the pathogen is M.tb and the pathogen protein is one or more of PtpA, PtpB, SapM, ESAT-6, and Rv2966c.
[0628] In a preferred embodiment, the target protein is Mtb protein tyrosine phosphatases (Ptp). Ptps belong to a large family of signaling enzymes and are required for optimal bacillary survival. PTPs, with protein tyrosine kinases, regulate numerous cellular functions, such as cell growth, proliferation, differentiation, metabolism, and immune response. M.tb encodes PtpA and PtpB and secretes them into the cytoplasm of host macrophages. PtpA prevents phagolysosome acidification by dephosphorylation of its substrate, Human Vacuolar Protein Sorting 33B. This results in the exclusion of the macrophage vacuolar-H+-ATPase (V-ATPase) from the vesicle. Once inside the macrophage, mPTPB activates Akt signaling and simultaneously blocks ERK1/2 and p38 activation thereby preventing host macrophage apoptosis and cytokine production. Inhibition of PtpA and PtpB decreases Mtb survival. See e.g., Dutta N.K. et al. Mycobacterial Protein Tyrosine Phosphatases A and B Inhibitors Augment the Bactericidal Activity of the Standard Anti-tuberculosis Regimen. ACS Infect Dis. 2016; 2(3):231-239 and Ruddraraju, K.V. et al. Therapeutic Targeting of Protein Tyrosine Phosphatases from Mycobacterium tuberculosis. Microorganisms 2021, 9(1), 14 incorporated herein by reference.
[0629] In an example embodiment, a method of treating Mycobacterium tuberculosis in macrophages is provided, comprising administering chimeric small molecule of the present invention. In one example, the small molecule comprises a MAPK kinase binder, a linker, an electrophilic reactive group, and a Mycobacterium target binding moiety. In one example embodiment, the molecule comprises a binder of MAPK p38a based on the inhibitor SB203580 that further comprises an azide bioorthogonal group. The binding moiety comprises a linker connected to the electrophilic reactive group N-acyl-N-alkyl sulfonamide. The electrophilic reactive group, in turn, is connected to the Mtb protein target binding moiety for PtpA via a linker. Upon binding to the MAPK kinase via SB203580, proximal lysines of the binding pocket of p38a MAPK, K15, K54, K66, K152, K165, will react with the lysine-reactive group (e.g., N-acyl-N- alkyl sulfonamide) and expel the kinase inhibitor, leaving the MAPK tagged with the PtpA binder. The kinase whichh is covalently labeled with the PtpA binder can then hyper and/or neo- phosphorylate the Mtb PtpA proteins, which can lead to HLA-display and generation of a strong immune response against the pathogen-specific phosphopeptides, allowing deactivation and elimination of infected macrophages by the immune system. Administration of a cyclooctyne coupling molecule can quench the azide biorthogonal group displayed on the kinase binding molecule, and deactivate the expelled kinase binding moiety.
[0630] In one preferred embodiment, the target protein is SapM. M. tb produces SapM, a alkaline phosphatase, for survival as it inhibits phagosome maturation in host macrophages. See e.g., Fernandez-Soto, P., Et. al. Mechanism of catalysis and inhibition of Mycobacterium tuberculosis SapM, implications for the development of novel antivirulence drugs. Sci Rep 2019, 9, 10315 and Fernandez-Soto, P., et al. Discovery of uncompetitive inhibitors of SapM that compromise intracellular survival of Mycobacterium tuberculosis. Sci Rep 2021, 11, 7667. incorporated herein by reference. [0631] In one example embodiment, the target protein is ESAT-6. M Tb. produces ESAT-6 to mediate regulation of host immune responses. ESAT-6 directly inhibits T cell IFN-y production by activation of p38 MAPK and indirectly through reprogramming of antigen presenting cells to produce less IL-12p70, an essential IFN-y stimulating cytokine. Jung, BG., et al. Early Secreted Antigenic Target of 6-kDa of Mycobacterium tuberculosis Stimulates IL-6 Production by Macrophages through Activation of STAT3. Sci Rep 2017, 7, 40984.
[0632] In one example embodiment, the target protein is Rv2966c. Rv2966c is a RsmD-like methyltransferase, which carries out the transferase function through its N-terminal domain. This protein has been identified as a potential therapeutic target for its role in the function of M. tb and a conserved subunit similar to that of ATP binding pocket of kinases. The highly conserved subunit is called S-adenosyl-methionine (SAM). In one example embodiment, the Rv2966c binding moiety targets a SAM subunit. See e.g., Kumar A., et al. “Structural and Functional Characterization of Rv2966c Protein Reveals an RsmD-like Methyltransferase from Mycobacterium tuberculosis and the Role of Its N-terminal Domain in Target Recognition” J Biol Chem. 2011, 286(22): 19652-19661 and Copeland, R., et al. “Protein methyltransferases as a target class for drug discovery.” Nat Rev Drug Discov 2009, 8, 724-732, incorporated herein by reference.
[0633] Uridine 5 '-monophosphate kinase (UMPK) catalyzes the reversible transfer of the y- phosphoryl group from ATP to UMP in the presence of a divalent cation, usually Mg2+. Sequence comparisons of bacterial UMPKs show they do not resemble UMPKs from other organisms. Furthermore, bacterial UMPKs are specific for UMP and exist in solution as stable homohexamers. See e.g., Rostirolla D. C., et al. “UMP Kinase from Mycobacterium Tuberculosis: Mode of Action and Allosteric Interactions, and Their Likely Role in Pyrimidine Metabolism Regulation.” Archives of Biochemistry and Biophysics 2011, 505 (2), 202-212.
[0634] In one aspect, the method comprises treating infection by a pathogen as a result of PsA. PsA is a gram-negative, rod-shaped bacterium that commonly causes nosocomial pneumonia. In an example embodiment, the chimeric small molecule target binding moiety targets the pathogen PsA and is Colistin. Colistin, a polymyxin, is sulfomethylated and naturally ineffective antibiotic. Within the body at physiological temperature and pH, Colistin is hydrolyzed and becomes active. Colistin binds to phospholipids and disrupts the bacterial cell membrane. See e.g., Levin A. S., et al. Intravenous Colistin as Therapy for Nosocomial Infections Caused by Multidrug-Resistant Pseudomonas aeruginosa and Acinetobacterbaumannii, Clinical Infectious Diseases 1999, 28, (5), 1008-1011. Colistin binds to lipopolysaccharide in the bacterial outer membrane, and also targets lipopolysaccharide in the cytoplasmic membrane. See, e.g., Sabnis et al., 2019, Colistin kills bacteria by targeting lipopolysaccharide in the cytoplasmic membrane, eLife doi: 10.7554/eLife.65836.

Administration of the Pharmaceutical Formulations
[0670] The pharmaceutical formulations or dosage forms thereof described herein can be administered one or more times hourly, daily, monthly, or yearly (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or more times hourly, daily, monthly, or yearly). In some embodiments, the pharmaceutical formulations or dosage forms thereof described herein can be administered continuously over a period of time ranging from minutes to hours to days. Devices and dosages forms are known in the art and described herein that are effective to provide continuous administration of the pharmaceutical formulations described herein. In some embodiments, the first one or a few initial amount(s) administered can be a higher dose than subsequent doses. This is typically referred to in the art as a loading dose or doses and a maintenance dose, respectively. In some embodiments, the pharmaceutical formulations can be administered such that the doses over time are tapered (increased or decreased) overtime so as to wean a subject gradually off of a pharmaceutical formulation or gradually introduce a subject to the pharmaceutical formulation.
[0671] As previously discussed, the pharmaceutical formulation can contain a predetermined amount of a primary active agent, secondary active agent, and/or pharmaceutically acceptable salt thereof where appropriate. In some of these embodiments, the predetermined amount can be an appropriate fraction of the effective amount of the active ingredient. Such unit doses may therefore be administered once or more than once a day, month, or year (e.g., 1, 2, 3, 4, 5, 6, or more times per day, month, or year). Such pharmaceutical formulations may be prepared by any of the methods well known in the art.
[0672] Where co-therapies or multiple pharmaceutical formulations are to be delivered to a subject, the different therapies or formulations can be administered sequentially or simultaneously. Sequential administration is administration where an appreciable amount of time occurs between administrations, such as more than about 15, 20, 30, 45, 60 minutes or more. The time between administrations in sequential administration can be on the order of hours, days, months, or even years, depending on the active agent present in each administration. Simultaneous administration refers to administration of two or more formulations at the same time or substantially at the same time (e.g., within seconds or just a few minutes apart), where the intent is that the formulations be administered together at the same time.
Delivery and Administration
[0673] Methods for modifying a target of interest comprises administering or delivering or otherwise contacting a cell via one or more methods known in the art, including without limitation, microinjection, electroporation, sonoporation, biolistics, calcium phosphate-mediated transfection, cationic transfection, liposome transfection, dendrimer transfection, heat shock transfection, nucleofection transfection, magnetofection, lipofection, impalefection, optical transfection, proprietary agent-enhanced uptake of nucleic acids, and delivery via liposomes, immunoliposomes, virosomes, or artificial virions. In some methods, the composition is introduced into an embryo by microinjection. The compositions may be microinjected into the nucleus or the cytoplasm of the embryo.
[0674] An actively targeting lipid particle or nanoparticle or liposome or lipid bilayer delivery system (generally as to embodiments of the invention, “lipid entity of the invention” delivery systems) are prepared by conjugating targeting moieties, including small molecule ligands, peptides and monoclonal antibodies, on the lipid or liposomal surface; for example, certain receptors, such as folate and transferrin (Tf) receptors (TfR), are overexpressed on many cancer cells and have been used to make liposomes tumor cell specific. Liposomes that accumulate in the tumor microenvironment can be subsequently endocytosed into the cells by interacting with specific cell surface receptors. To efficiently target liposomes to cells, such as cancer cells, it is useful that the targeting moiety have an affinity for a cell surface receptor and to link the targeting moiety in sufficient quantities to have optimum affinity for the cell surface receptors; and determining these aspects are within the ambit of the skilled artisan. In the field of active targeting, there are a number of cell-, e.g., tumor-, specific targeting ligands.
[0675] Also as to active targeting, with regard to targeting cell surface receptors such as cancer cell surface receptors, targeting ligands on liposomes can provide attachment of liposomes to cells, e.g., vascular cells, via a nonintemalizing epitope; and, this can increase the extracellular concentration of that which is being delivered, thereby increasing the amount delivered to the target cells. A strategy to target cell surface receptors, such as cell surface receptors on cancer cells, such as overexpressed cell surface receptors on cancer cells, is to use receptor-specific ligands or antibodies. Many cancer cell types display upregulation of tumor-specific receptors. For example, TfRs and folate receptors (FRs) are greatly overexpressed by many tumor cell types in response to their increased metabolic demand. Folic acid can be used as a targeting ligand for specialized delivery owing to its ease of conjugation to nanocarriers, its high affinity for FRs and the relatively low frequency of FRs, in normal tissues as compared with their overexpression in activated macrophages and cancer cells, e.g., certain ovarian, breast, lung, colon, kidney and brain tumors. Overexpression of FR on macrophages is an indication of inflammatory diseases, such as psoriasis, Crohn's disease, rheumatoid arthritis and atherosclerosis; accordingly, folate-mediated targeting of the invention can also be used for studying, addressing or treating inflammatory disorders, as well as cancers. Folate-linked lipid particles or nanoparticles or liposomes or lipid bilayers of the invention (“lipid entity of the invention”) deliver their cargo intracellularly through receptor-mediated endocytosis. Intracellular trafficking can be directed to acidic compartments that facilitate cargo release, and, most importantly, release of the cargo can be altered or delayed until it reaches the cytoplasm or vicinity of target organelles. Delivery of cargo using a lipid entity of the invention having a targeting moiety, such as a folate-linked lipid entity of the invention, can be superior to nontargeted lipid entity of the invention. The attachment of folate directly to the lipid head groups may not be favorable for intracellular delivery of folate-conjugated lipid entity of the invention, since they may not bind as efficiently to cells as folate attached to the lipid entity of the invention surface by a spacer, which may can enter cancer cells more efficiently. A lipid entity of the invention coupled to folate can be used for the delivery of complexes of lipid, e.g., liposome, e.g., anionic liposome and virus or capsid or envelope or virus outer protein, such as those herein discussed such as adenovirus or AAV. Tf is a monomeric serum glycoprotein of approximately 80 KDa involved in the transport of iron throughout the body. Tf binds to the TfR and translocates into cells via receptor-mediated endocytosis. The expression of TfR can be higher in certain cells, such as tumor cells (as compared with normal cells and is associated with the increased iron demand in rapidly proliferating cancer cells. Accordingly, the invention comprehends a TfR-targeted lipid entity of the invention, e.g., as to liver cells, liver cancer, breast cells such as breast cancer cells, colon such as colon cancer cells, ovarian cells such as ovarian cancer cells, head, neck and lung cells, such as head, neck and non-small-cell lung cancer cells, cells of the mouth such as oral tumor cells.
[0676] Also, as to active targeting, a lipid entity of the invention can be multifunctional, i.e., employ more than one targeting moiety such as CPP, along with Tf; a chimeric small system; e.g., a combination of Tf and poly-L-arginine which can provide transport across the endothelium of the blood-brain barrier. EGFR is a tyrosine kinase receptor belonging to the ErbB family of receptors that mediates cell growth, differentiation and repair in cells, especially non-cancerous cells, but EGF is overexpressed in certain cells such as many solid tumors, including colorectal, non-small-cell lung cancer, squamous cell carcinoma of the ovary, kidney, head, pancreas, neck and prostate, and especially breast cancer. The invention comprehends EGFR-targeted monoclonal antibody(ies) linked to a lipid entity of the invention. HER-2 is often overexpressed in patients with breast cancer, and is also associated with lung, bladder, prostate, brain and stomach cancers. HER-2, encoded by the ERBB2 gene. The invention comprehends a HER-2-targeting lipid entity of the invention, e.g., an anti-HER-2-antibody(or binding fragment thereof)-lipid entity of the invention, a HER-2-targeting-PEGylated lipid entity of the invention (e.g., having an anti-HER-2- antibody or binding fragment thereof), a HER-2 -targeting-maleimide-PEG polymer- lipid entity of the invention (e g., having an anti-HER-2-antibody or binding fragment thereof). Upon cellular association, the receptor-antibody complex can be internalized by formation of an endosome for delivery to the cytoplasm. With respect to receptor-mediated targeting, the skilled artisan takes into consideration ligand/target affinity and the quantity of receptors on the cell surface, and that PEGylation can act as a barrier against interaction with receptors. The use of antibody-lipid entity of the invention targeting can be advantageous. Multivalent presentation of targeting moieties can also increase the uptake and signaling properties of antibody fragments. In practice of the invention, the skilled person takes into account ligand density (e.g., high ligand densities on a lipid entity of the invention may be advantageous for increased binding to target cells). Preventing early by macrophages can be addressed with a sterically stabilized lipid entity of the invention and linking ligands to the terminus of molecules such as PEG, which is anchored in the lipid entity of the invention (e g., lipid particle or nanoparticle or liposome or lipid bilayer). The microenvironment of a cell mass such as a tumor microenvironment can be targeted; for instance, it may be advantageous to target cell mass vasculature, such as the tumor vasculature microenvironment. Thus, the invention comprehends targeting VEGF. VEGF and its receptors are well-known proangiogenic molecules and are well -characterized targets for anti angiogenic therapy. Many small-molecule inhibitors of receptor tyrosine kinases, such as VEGFRs or basic FGFRs, have been developed as anticancer agents and the invention comprehends coupling any one or more of these peptides to a lipid entity of the invention, e.g., phage IVO peptide(s) (e.g., via or with a PEG terminus), tumor-homing peptide APRPG (SEQ ID NO: 47) such as APRPG- PEG-modified. VCAM, the vascular endothelium plays a key role in the pathogenesis of inflammation, thrombosis and atherosclerosis. CAMs are involved in inflammatory disorders, including cancer, and are a logical target, E- and P-selectins, VCAM-1 and ICAMs. Can be used to target a lipid entity of the invention., e.g., with PEGylation. Matrix metalloproteases (MMPs) belong to the family of zinc-dependent endopeptidases. They are involved in tissue remodeling, tumor invasiveness, resistance to apoptosis and metastasis. There are four MMP inhibitors called TIMP1-4, which determine the balance between tumor growth inhibition and metastasis; a protein involved in the angiogenesis of tumor vessels is MT1-MMP, expressed on newly formed vessels and tumor tissues. The proteolytic activity of MT1-MMP cleaves proteins, such as fibronectin, elastin, collagen and laminin, at the plasma membrane and activates soluble MMPs, such as MMP- 2, which degrades the matrix. An antibody or fragment thereof such as a Fabz fragment can be used in the practice of the invention such as for an antihuman MT1-MMP monoclonal antibody linked to a lipid entity of the invention, e.g., via a spacer such as a PEG spacer, a [3 -integrins or integrins are a group of transmembrane glycoprotein receptors that mediate attachment between a cell and its surrounding tissues or extracellular matrix. Integrins contain two distinct chains (heterodimers) called a - and /? -subunits. The tumor tissue-specific expression of integrin receptors can be utilized for targeted delivery in the invention, e.g., whereby the targeting moiety can be an RGD peptide such as a cyclic RGD. Aptamers are ssDNA or RNA oligonucleotides that impart high affinity and specific recognition of the target molecules by electrostatic interactions, hydrogen bonding and hydrophobic interactions as opposed to the Watson-Crick base pairing, which is typical for the bonding interactions of oligonucleotides. Aptamers as a targeting moiety can have advantages over antibodies: aptamers can demonstrate higher target antigen recognition as compared with antibodies; aptamers can be more stable and smaller in size as compared with antibodies; aptamers can be easily synthesized and chemically modified for molecular conjugation; and aptamers can be changed in sequence for improved selectivity and can be developed to recognize poorly immunogenic targets. Such moieties as a sgc8 aptamer can be used as a targeting moiety (e.g., via covalent linking to the lipid entity of the invention, e.g., via a spacer, such as a PEG spacer). The targeting moiety can be stimuli-sensitive, e g., sensitive to an externally applied stimuli, such as magnetic fields, ultrasound or light; and pH-triggering can also be used, e.g., a labile linkage can be used between a hydrophilic moiety such as PEG and a hydrophobic moiety such as a lipid entity of the invention, which is cleaved only upon exposure to the relatively acidic conditions characteristic of the a particular environment or microenvironment such as an endocytic vacuole or the acidotic tumor mass. pH-sensitive copolymers can also be incorporated in example embodiments of the invention can provide shielding; diortho esters, vinyl esters, cysteine- cleavable lipopolymers, double esters and hydrazones are a few examples of pH-sensitive bonds that are quite stable at pH 7.5, but are hydrolyzed relatively rapidly at pH 6 and below, e.g., a terminally alkylated copolymer of N-isopropyl acrylamide and methacrylic acid that copolymer facilitates destabilization of a lipid entity of the invention and release in compartments with decreased pH value; or, the invention comprehends ionic polymers for generation of a pH- responsive lipid entity of the invention (e.g., poly(methacrylic acid), poly(diethylaminoethyl methacrylate), poly(acrylamide) and poly(acrylic acid)). Temperature-triggered delivery is also within the ambit of the invention. Many pathological areas, such as inflamed tissues and tumors, show a distinctive hyperthermia compared with normal tissues. Utilizing this hyperthermia is an attractive strategy in cancer therapy since hyperthermia is associated with increased tumor permeability and enhanced uptake. This technique involves local heating of the site to increase microvascular pore size and blood flow, which, in turn, can result in an increased extravasation of embodiments of the invention. Temperature-sensitive lipid entity of the invention can be prepared from thermosensitive lipids or polymers with a low critical solution temperature. Above the low critical solution temperature (e.g., at site such as tumor site or inflamed tissue site), the polymer precipitates, disrupting the liposomes to release. Lipids with a specific gel-to-liquid phase transition temperature are used to prepare these lipid entities of the invention; and a lipid for a thermosensitive embodiment can be dipalmitoylphosphatidylcholine. Thermosensitive polymers can also facilitate destabilization followed by release, and a useful thermosensitive polymer is poly (N-isopropylacrylamide). Another temperature triggered system can employ lysolipid temperature-sensitive liposomes. The invention also comprehends redox-triggered delivery: The difference in redox potential between normal and inflamed or tumor tissues, and between the intra- and extra-cellular environments has been exploited for delivery; e.g., GSH is a reducing agent abundant in cells, especially in the cytosol, mitochondria and nucleus. The GSH concentrations in blood and extracellular matrix are just one out of 100 to one out of 1000 of the intracellular concentration, respectively. This high redox potential difference caused by GSH, cysteine and other reducing agents can break the reducible bonds, destabilize a lipid entity of the invention and result in release of payload. The disulfide bond can be used as the cleavable/reversible linker in a lipid entity of the invention, because it causes sensitivity to redox owing to the disulfideto-thiol reduction reaction; a lipid entity of the invention can be made reduction sensitive by using two (e.g., two forms of a disulfide-conjugated multifunctional lipid as cleavage of the disulfide bond (e g., via tris(2-carboxyethyl)phosphine, dithiothreitol, L-cysteine or GSH), can cause removal of the hydrophilic head group of the conjugate and alter the membrane organization leading to release of payload. Calcein release from reduction-sensitive lipid entity of the invention containing a disulfide conjugate can be more useful than a reduction-insensitive embodiment. Enzymes can also be used as a trigger to release payload. Enzymes, including MMPs (e.g., MMP2), phospholipase A2, alkaline phosphatase, transglutaminase or phosphatidylinositol-specific phospholipase C, have been found to be overexpressed in certain tissues, e.g., tumor tissues. In the presence of these enzymes, specially engineered enzyme-sensitive lipid entity of the invention can be disrupted and release the payload, an MMP2-cleavable octapeptide (Gly-Pro-Leu-Gly-Ile-Ala- Gly-Gln) (SEQ ID NO: 48) can be incorporated into a linker, and can have antibody targeting, e.g., antibody 2C5. The invention also comprehends light-or energy-triggered delivery, e.g., the lipid entity of the invention can be light-sensitive, such that light or energy can facilitate structural and conformational changes, which lead to direct interaction of the lipid entity of the invention with the target cells via membrane fusion, photo-isomerism, photofragmentation or photopolymerization; such a moiety therefor can be benzoporphyrin photosensitizer. Ultrasound can be a form of energy to trigger delivery; a lipid entity of the invention with a small quantity of particular gas, including air or perfluorated hydrocarbon can be triggered to release with ultrasound, e.g., low-frequency ultrasound (LFUS). Magnetic delivery: A lipid entity of the invention can be magnetized by incorporation of magnetites, such as Fe3O4 or y-Fe2O3, e.g., those that are less than 10 nm in size. Targeted delivery can be then by exposure to a magnetic field.
[0677] Also as to active targeting, the invention also comprehends intracellular delivery. Since liposomes follow the endocytic pathway, they are entrapped in the endosomes (pH 6.5-6) and subsequently fuse with lysosomes (pH <5), where they undergo degradation that results in a lower therapeutic potential. The low endosomal pH can be taken advantage of to escape degradation. Fusogenic lipids or peptides, which destabilize the endosomal membrane after the conformational transit! on/activati on at a lowered pH. Amines are protonated at an acidic pH and cause endosomal swelling and rupture by a buffer effect Unsaturated dioleoylphosphatidylethanolamine (DOPE) readily adopts an inverted hexagonal shape at a low pH, which causes fusion of liposomes to the endosomal membrane. This process destabilizes a lipid entity containing DOPE and releases the cargo into the cytoplasm; fusogenic lipid GALA (SEQ ID NO: 49), cholesteryl-GALA and PEG- GALA may show a highly efficient endosomal release; a pore-forming protein listeriolysin O may provide an endosomal escape mechanism; and, histidine-rich peptides have the ability to fuse with the endosomal membrane, resulting in pore formation, and can buffer the proton pump causing membrane lysis.
[0678] Also as to active targeting, cell-penetrating peptides (CPPs) facilitate uptake of macromolecules through cellular membranes and, thus, enhance the delivery of CPP-modified molecules inside the cell. CPPs can be split into two classes: amphipathic helical peptides, such as transportan and MAP, where lysine residues are major contributors to the positive charge; and Arg-rich peptides, such as TATp, Antennapedia or penetratin. TATp is a transcription-activating factor with 86 amino acids that contains a highly basic (two Lys and six Arg among nine residues) protein transduction domain, which brings about nuclear localization and RNA binding. Other CPPs that have been used for the modification of liposomes include the following: the minimal protein transduction domain of Antennapedia, a Drosophila homeoprotein, called penetratin, which is a 16-mer peptide (residues 43-58) present in the third helix of the homeodomain; a 27- amino acid-long chimeric CPP, containing the peptide sequence from the amino terminus of the neuropeptide galanin bound via the Lys residue, multipara, a wasp venom peptide; VP22, a major structural component of HSV-1 facilitating intracellular transport and transportan (18-mer) amphipathic model peptide that translocates plasma membranes of mast cells and endothelial cells by both energy-dependent and -independent mechanisms. The invention comprehends a lipid entity of the invention modified with CPP(s), for intracellular delivery that may proceed via energy dependent micropinocytosis followed by endosomal escape. The invention further comprehends organelle-specific targeting. A lipid entity of the invention surface-functionalized with the triphenyl phosphonium (TPP) moiety or a lipid entity of the invention with a lipophilic cation, rhodamine 123 can be effective in delivery of cargo to mitochondria. DOPE/sphingomyelin/stearyl-octa-arginine can delivers cargos to the mitochondrial interior via membrane fusion. A lipid entity of the invention surface modified with a lysosomotropic ligand, octadecyl rhodamine B can deliver cargo to lysosomes. Ceramides are useful in inducing lysosomal membrane permeabilization; the invention comprehends intracellular delivery of a lipid entity of the invention having a ceramide. The invention further comprehends a lipid entity of the invention targeting the nucleus, e.g., via a DNA-intercalating moiety. The invention also comprehends multifunctional liposomes for targeting, i.e., attaching more than one functional group to the surface of the lipid entity of the invention, for instance to enhances accumulation in a desired site and/or promotes organelle-specific delivery and/or target a particular type of cell and/or respond to the local stimuli such as temperature (e.g., elevated), pH (e.g., decreased), respond to externally applied stimuli such as a magnetic field, light, energy, heat or ultrasound and/or promote intracellular delivery of the cargo. All of these are considered actively targeting moi eties.
[0679] An embodiment of the system may comprise an actively targeting lipid particle or nanoparticle or liposome or lipid bilayer delivery system; or a lipid particle or nanoparticle or liposome or lipid bilayer comprising a targeting moiety whereby there is active targeting or wherein the targeting moiety is an actively targeting moiety. A targeting moiety can be one or more targeting moieties, and a targeting moiety can be for any desired type of targeting such as, e.g., to target a cell such as any herein-mentioned; or to target an organelle such as any herein- mentioned; or for targeting a response such as to a physical condition such as heat, energy, ultrasound, light, pH, chemical such as enzymatic, or magnetic stimuli; or to target to achieve a particular outcome such as delivery of payload to a particular location, such as by cell penetration. [0680] It should be understood that as to each possible targeting or active targeting moiety herein discussed, there is one example embodiment of the invention wherein the delivery system comprises such a targeting or active targeting moiety.
[0681] Further embodiments are illustrated in the following Examples which are given for illustrative purposes only and are not intended to limit the scope of the invention.
Methods of Screening
[0682] Methods of screening for the combination of the protein binding moieties to be provided in the chimeric small molecule are provided herein. In one embodiment, the methods of screening identify binders of a protein target substrate. In one embodiment, the kinase binding moiety is a kinase inhibitor of an oncogenic fusion of a kinase target substrate. By way of example, reference in the screening embodiment described screening Abl kinase binders for BCR-ABL; however, the screening method described is applicable to identification of kinase binders of other target substrates utilized in chimeric small molecules detailed herein. In example methods of screening, binders, for example inhibitors of BCR-ABL are identified based on the binding location on Abl.
[0683] The methods of nucleic acid analysis can be utilized for screening of chemical libraries, and to identify additional binders for use within the context of the embodiments disclosed herein. [0684] In some embodiments, the disclosed methods can be used to screen chemical libraries for agents that bind kinase and modulate activation or inactivation of the same. By exposing cells, or fractions thereof, tissues, or even whole animals, to different members of the chemical libraries, and performing the methods described herein, different members of a chemical library can be screened for their effect on kinase binding and activation state.
[0685] In some embodiments, screening of test agents involves testing a combinatorial library containing a large number of potential modulator compounds. A combinatorial chemical library may be a collection of diverse chemical compounds generated by either chemical synthesis or biological synthesis, by combining a number of chemical "building blocks" such as reagents. For example, a linear combinatorial chemical library, such as a polypeptide library, is formed by combining a set of chemical building blocks (amino acids) in every possible way for a given compound length (for example the number of amino acids in a polypeptide compound). Millions of chemical compounds can be synthesized through such combinatorial mixing of chemical building blocks.
Screening for Chimeric Small Molecules
[0686] A further aspect of the invention relates to a method for identifying a chimeric small molecule capable of modulating one or more phenotypic aspects of a cell or cell population as disclosed herein, comprising: a) applying a candidate chimeric small agent to the cell or cell population; b) detecting modulation of one or more phenotypic aspects of the cell or cell population by the candidate agent, thereby identifying the agent. The phenotypic aspects of the cell or cell population that is modulated may be a gene signature or biological program specific to a cell type or cell phenotype or phenotype specific to a population of cells (e.g., an inflammatory phenotype or suppressive immune phenotype). In one example embodiment, steps can include administering candidate modulating agents to cells, detecting identified cell (sub)populations for changes in signatures, or identifying relative changes in cell (sub) populations which may comprise detecting relative abundance of particular gene signatures. [0687] The term “modulate” broadly denotes a qualitative and/or quantitative alteration, change or variation in that which is being modulated. Where modulation can be assessed quantitatively - for example, where modulation comprises or consists of a change in a quantifiable variable such as a quantifiable property of a cell or where a quantifiable variable provides a suitable surrogate for the modulation - modulation specifically encompasses both increase (e.g., activation) or decrease (e.g., inhibition) in the measured variable. The term encompasses any extent of such modulation, e.g., any extent of such increase or decrease, and may more particularly refer to statistically significant increase or decrease in the measured variable. By means of example, modulation may encompass an increase in the value of the measured variable by at least about 10%, e.g., by at least about 20%, preferably by at least about 30%, e.g., by at least about 40%, more preferably by at least about 50%, e.g., by at least about 75%, even more preferably by at least about 100%, e.g., by at least about 150%, 200%, 250%, 300%, 400% or by at least about 500%, compared to a reference situation without said modulation; or modulation may encompass a decrease or reduction in the value of the measured variable by at least about 10%, e.g., by at least about 20%, by at least about 30%, e.g., by at least about 40%, by at least about 50%, e.g., by at least about 60%, by at least about 70%, e.g., by at least about 80%, by at least about 90%, e g., by at least about 95%, such as by at least about 96%, 97%, 98%, 99% or even by 100%, compared to a reference situation without said modulation. Preferably, modulation may be specific or selective, hence, one or more desired phenotypic aspects of an immune cell or immune cell population may be modulated without substantially altering other (unintended, undesired) phenotypic aspect(s).
[0688] After the chimeric small molecule is applied, a representative cell sample can be subjected to analysis, for example at various time points, and compared to a control, such as a sample from an organism or cell, for example a cell from an organism, or a standard value. By exposing cells, or fractions thereof, tissues, or even whole animals, to different members of the chemical libraries, and performing the methods described herein, different members of a chemical library can be screened for their effect on immune phenotypes thereof simultaneously in a relatively short amount of time, for example using a high throughput method.

Millions of chemical compounds can be synthesized through such combinatorial mixing of chemical building blocks.
Computer Aided Electrophilic Reactive Linkers Design
[0690] Computer aided design (CAD) in the context of electrophilic reactive linkers comprises of computational methods to develop electrophilic reactive linkers for chimeric small molecules. Generally, CAD involves generating or obtaining a library of electrophilic reactive linkers for screening methods or Artificial Intelligence/Machine Learning (AI/ML) training. CAD methods comprising screening libraries may involve first selecting an enzyme, an enzyme binding moiety, a target binding moiety, and optionally a linker such as those described in the Linker section above. CAD screening methods may then utilize a generative algorithm to produce one or more chimeric small molecules with an electrophilic reactive linker designed to react with the enzyme and bind to a target. For example, a graph-based generative model may be used wherein the three- dimensional space is used to select an electrophilic reactive group bound to the chimeric small molecule that are within a defined distance to the nucleophile on the enzyme. In another example, the generative model may use natural language processing. For example, SMILES notation comprises embedded structural patterns and can be recognized by the generative model. These structural word patterns are then used to generate chimeric small molecules comprising electrophilic reactive groups that can bond to the desired enzyme.
[0691] CAD methods comprising AI/ML may comprise any regression model (e.g., neural networks) or classification network (e.g., Random Forest) to generate chimeric small molecules with an electrophilic reactive group. AI/ML CAD methods may be trained on the electrophilic reactive linker libraries, enzymes, targets, and chimeric small molecules. Trained AI/ML CAD methods can then take as input the target or the target and the enzyme. The AI/ML CAD model can then generate a chimeric small molecule capable of binding to the target comprising an electrophilic reactive linker that bonds to the enzyme. See e.g., Tunjic, T.M., Weber, N. and Brunsteiner, M., 2023. Computer aided drug design in the development of proteolysis targeting chimeras. Computational and Structural Biotechnology Journal. In example embodiments, the electrophilic reactive group is generated by CAD.
Heterobifunctional Molecules
[0692] Heterobifunctional molecules may be assembled using any combination of the above modifying binding moieties, electrophilic reactive linkers, and target binding moieties. The following description provides, by way of reference only, certain heterobifunctional molecules that can be generated according to the design principles and examples moieties provided above. In one aspect, a heterobifunctional molecule comprises an electrophilic reactive linker as described herein and a target polypeptide binding moiety attached to the electrophilic reactive linker on one end and a modifying polypeptide binding moiety attached to the linker on the opposite end. In example embodiments, the target polypeptide binding moiety is a polypeptide to which the modifying moiety is to be attached and modified by the modifying moiety.
[0693] In example embodiments, the electrophilic reactive linker connects the functional moieties of a proteolysis targeting chimeras (PROTAC), deubiquitinase-targeting chimeras (DUBTACs), Pho-repressive complex (PhoRC), dephosphorylation targeting chimera (DEPTAC), phosphorylation targeting chimeras (PhosTAC), acetylation tagging system (AceTAG), regulated induced proximity targeting chimeras (RIPTAC), Transcriptional/Epigenetic Chemical Inducers of Proximity (TCIP), Autophagy-Targeting Chimera (AUTAC), or Lysosome Targeting Chimeras (LYTAC) thereby creating a heterobifunctional molecule. See e.g., Peng, Y.; et al. Targeted Protein Posttranslational Modifications by Chemically Induced Proximity for Cancer Therapy, lournal of Biological Chemistry, 2023, 299, 104572.
[0694] Further embodiments are illustrated in the following Examples which are given for illustrative purposes only and are not intended to limit the scope of the invention.
[0695] It is considered the binding moieties, electrophilic reactive linkers, functional moieties, and components thereof may and can be modified, both chemically and physically, to substitute, remove, or add components described herein or known in the art to arrive at the claimed subject matter. In particular, it may be that components of the claimed invention, for example, are illustrated with complete or filled valences in which there appears to be no specific connection point between one component and another component of the claimed invention. However, between the example constructs described herein and the ordinary skill in the art, one can readily assemble the compounds claimed by modifying an atom with a fdled valency to accept a new bond. A lack of an open bonding position should not be construed as an intended closed system. Instead, the terminal groups of compounds described herein are considered as possible bonding positions to arrive at the claimed invention. Furthermore, it will be understood by a person having ordinary skill in the art that a terminal alkyne on a component of the chimeric small molecule may be an indicator of a possible bonding point wherein any chemistry known in the art may be used to bond said component to the chimeric small molecule (e.g., using click chemistry).
EXAMPLES
Example 1 - Chimeric Small Molecules
Harnessing Enzyme Inhibitors to Build Chimeras
[0696] Exemplary chimeric small molecules are formed by joining a kinase binder with a binder of a target protein-of-interest. Here, Applicants used the inhibitor-directed site-selective fast labeling of the kinase with the target binding moiety. Inhibitors tethered with a chemoselective electrophilic reactive group exhibit site-specific labeling of a side chain nucleophilic residue proximal to the inhibitor binding site, this approach has worked for several inhibitors. To neutralize the inhibitor following labeling, Applicants used bio-orthogonal handles (e.g., using cyclopropyl or azide) that do not perturb the binding of the inhibitor to the kinase. Upon completion of the proximity-induced labeling reaction, the cells will be treated with a large reactive group (e.g., tetrazine, cyclooctyne) whose conjugation will prevent the inhibitor from binding to the kinase, thereby deactivating the inhibitor. Applicants leveraged readily available inhibitors with low residence time (high koff) to allow rapid labeling and quenching.
Development and Application of Kinase-Binder Platform
[0697] In this work, Applicants developed and applied the novel kinase binder platform to find binders to label the kinases via proximity-induced labeling. Here, Applicants turned kinase inhibitors into labelers with the trifunctional molecule (kinase inhibitor-lysine reactive group-A7. /A protein targeting group). The molecules bind to kinases via the kinase inhibitor, proximal lysines react with the lysine-reactive group (e.g., N-acyl-N-alkyl sulfonamide or NASA), and expel the kinase inhibitor, leaving the kinase tagged with an M.tb binder. The kinases, then covalently labeled with an M.tb binder, will hyper- and/or neo-phosphorylate the M.tb proteins, leading to HLA-display and an immune response. The kinase inhibitor contains a small bio-orthogonal group (e g., cyclopropenyl, azide, tetrazine) that does not perturb the binding of the inhibitor to the kinase, and the inhibitor is quenched (e.g., with cyclooctyne), so the bulky group prevents the inhibitor from binding to the kinase. Applicants optimized NASA (covalent labeling) chemistry (see below) and optimized quenching the inhibitor (see below). Applicants focused on the NASA electrophilic reactive group since it is one of the most rapid cell-compatible proximity-induced labeling reagents, which was successfully used for labeling of PKC kinase by Applicants.
Design and Optimization of NASA Chemistry for 5 Kinase Inhibitors
[0698] Applicants selected five kinases to optimize the NASA chemistry to label kinases with an inhibitor: MAPK, EGFR, ABL, CDK8, and P13K (FIGI 8). These kinases and inhibitors were chosen based on the following criteria (1) high kinase abundance in macrophages, (2) well- established binders with nanomolar activity, available crystal structure, and low residence time to ensure efficiency of the deactivation step, (3) binder should accommodate a small biorthogonal handle without affecting its binding potency/residence time (4) high density of lysines on the kinase close to the binding pocket, (5) labeling of kinase should not interfere with its enzymatic activity. For example, to design a probe for labeling of p38a MAPK, Applicants have chosen the following three binders: SB203580, Skepinone-B and Sorafenib with residence times 5, 150 and 88 seconds respectively (FIG. 18). The crystal structure of SB203580 (PDB: 3GCP) shows that linker attachment at the sulfoxide should not affect binding, and lysines (KI 5, K54, K66, KI 52, KI 65) are in close proximity to the binding pocket. Docking studies show that attachment of azide in ortho position to the fluoro group does not interfere with binding; however, the product of click reaction does not bind to p38a. Similar analysis of crystal structures for Skepinone (PDB: 3QUE) and Sorafenib (PDB: 3HEG) were performed. Gefitinib, Imatinib, Idelasilib and compound 5 were selected as binders of EGFR, ABL, PI3K and CDK8, respectively, due to their relatively low residence time (7s - 17min) and high availability of lysines in the close proximity to binding pockets (6 Lys for EGFR, 10 Lys for ABL, 6 Lys for CDK8, and 10 Lys for PI3K). For all of the inhibitors shown in FIG.16, Applicants optimized labeling by creating trifunctional probes with kinase binder-NASA group-coumarin and measure labeling via in-gel fluorescence of cell lysate after treatment with probes. Representative examples of fluorescent probe and mechanism of labeling are shown in FIG 17A. As an alternative to NASA, dibromophenyl benzoate and N- sulfonyl pyridone electrophilic reactive groups will be considered. Applicants chose binders with 3 linkers per kinase (5 kinases total) to synthesize coumarin probes with and without the orthogonal binding group (15 compounds x 2 variations = 30 compounds), prioritizing the best 3 kinase- inhibitor pairs.
Design and Optimize Bioorthogonal Chemistry for 5 Kinase Inhibitors
[0699] Applicants focused on click reaction between azide (substituent on kinase inhibitor) and cyclooctyne (quenching reagent) as a deactivating step. Mechanism of inhibitor deactivation is illustrated in FIG 17 and 19 where click renders the kinase inactive. Alternatively, inverse Diels- Alder reaction between tetrazine (bioisostere of phenyl) and trans-cyclooctene or cyclopropene will be considered. To optimize biorthogonal chemistry, various quenching reagents will be added to cells pretreated with optimized probes. Reaction conditions for the quenching step will be varied (concentration of coupling molecule, incubation time) and the activity of labeled kinases towards their natural substrates will be evaluated. Applicants measured if the kinase is quenched by looking at the kinase-substrate phosphorylation. If the kinase inhibitor is quenched, then the kinase phosphorylation of its substrate will be returned to basal levels.
Target Selection: Immune Evasion is a Hallmark of PsA and M.tb.
[0700] The gram-negative pathogen PsA remains a serious human health threat with increasing instances of antibiotic-resistance and immune-system evasion. The outer membrane of PsA acts as a physical barrier for antibiotics and hinders recognition by the immune system. Upon initial infection, the bacterium secretes alkaline protease and elastase, which degrade the complement protein C3b. Moreover, lipopolysaccharide (LPS) variants can interfere with C3b deposition. During the late stages of infection, PsA forms biofdms that protect the bacteria from complement- mediated phagocytosis. The forced recruitment of complement proteins, antibodies, or macrophages to PsA at high, local concentrations using chimeras empowers the immune system to deactivate these pathogens.
[0701] M.tb. also evades the host immune system through multiple mechanisms. The bacteria enter macrophages by conjugating to the complement proteins and subsequently uses their ESX-1 apparatus to secrete proteins that block endosome acidification and the immune system. For example, M.tb. attenuates antigen processing and MHC-II expression, secretes ESAT-6 to aid in phagosomal escape and intracellular survival and secretes protein tyrosine phosphatase A (PtpA) and mammalian cell entry protein 3E (Mce3E) to suppress the innate immune responses. PtpA, PtpB and SapM (secreted acid phosphatase) act on H+-V-ATPase and phosphatidylinositol, respectively, to prevent the phagosome acidification and maturation. M.tb limits the autophagy initiation by secreting enhanced intracellular survival protein, which rapidly acetylates host dual proteins phosphatase (DUSP16) and mitogen-activated protein kinase phosphatase-7 (MKP-7). [0702] Recently, Applicants demonstrated the ability of phosphorylation-inducing chimeric small molecules (PHICS) to hyper-phosphorylate a non-native substrate of the kinase. Protein hyperphosphorylation not only deactivates the protein, but it also appends neo-epitopes on the target, which can potentially be recognized by the immune system (via HLA display) to evoke a robust immune response. Since M. tb secretes its several key proteins (e g., PtpA, PtpB, SapM, ESAT-6, Rv2966c) in macrophages, Applicants will develop PHICS against these targets and demonstrate clearance of the infected macrophages by T cells.
PHosphorylation-Inducing Chimeric Small molecules (PHICS)
[0703] Neo-phosphorylations (unobserved in the native cellular environment) can also alter protein structure and function, and evoke immune response. PHICS-mediated neo- phosphorylation on M.tb proteins may evoke a strong immune response against the pathogen- specific phosphopeptides, allowing deactivation and elimination of infected macrophages by the immune system. Several phosphorylation sites recruit ubiquitin ligase and signal degradation. As such, PHICS may enable the deactivation and degradation of targeted proteins. Finally, the proposal to incorporate kinase inhibitors using proximity-induced labeling chemistries will allow engagement of kinases that are highly abundant in macrophages, thereby increasing opportunities to induce a desired therapeutic outcome.
[0704] Applicants note that PHICS will complement PROTACs in multiple ways. For example, PHICS can have several target sites (Ser, Thr, Tyr, and His) while PROTACs target only lysine. The efficiency of PROTAC depends on the efficiency of ubiquitination, which is a complex process compared to phosphorylation. Ubiquitination is a multistep modification involving the appendage of a protein and often yields a heterogeneous mixture of poly-ubiquitinated species in substoichiometric amounts. Phosphorylation is relatively simple, involving the appendage of a small phosphoryl group, which does not concatenate to form chains. Finally, ubiquitination involves large complexes compared to those of kinases. Additionally, PHICS target AT. tb secretory proteins and kinases abundant in macrophages. Therefore, immune response induced by neo- phosphorylations will be more selective towards infected cells. Because of its catalytic nature, PHICS may produce more prolonged effects until the clearance of the infected cells. PROTAC may inhibit the activity of aM.tb protein by degradation, but it is envisioned that PHICS-induced immune response would destroy the infected cell, preventing a subsequent infection of surrounding cells.

Example 2
[0707] Bifunctional molecules are extensively used to degrade proteins via induced-proximity effects, albeit newer applications beyond protein degradation are arising.10 7 The appendage of a phosphoryl group alters the protein’s electrostatic surface topology, dynamics, and functions.6’7 Unsurprisingly, small molecules that block protein phosphorylation via kinase inhibition have had a transformative impact on basic science and medicine.8 The data suggest that PHICS that induce phosphorylation of any given protein-of-interest on-demand are useful in myriad scenarios. We recently reported the first examples of PHICS for Serine/Threonine phosphorylation using two kinases (AMPK, PKC)11 and will shortly report induction of tyrosine phosphorylation and signal transduction using PHICS that recruits Abelson (ABL) kinase (manuscript in preparation).
[0708] For example, using PHICS 1.1 (Fig. 34A, B) and engineered EGFR receptor bearing FKBPF36V, Applicants recruited Abelson kinase (ABL) to EGFR. This recruitment led to the induction of signalling relevant phosphorylations on EGFR by PHICS but not in DMSO or ABL binder 1.2 (Fig. 34C). Furthermore, Applicants used a previously described luciferase-based reporter gene assay with serum response element (SRE)12 to monitor EGFR signaling activation and observed two-fold high luciferase activity for PHICS 1.1 compared to DMSO or ABL binder 1.2 (Fig. 34D). In another example of bioactivity, a PKC PHICS phosphorylated BCR-ABL at T735, a known binding site for 14-3-3 protein, resulting in BCR-ABL sequestration and death of Chronic Myeloid Leukemia (CML) cells (see fig. 36B-D in ref2).
[0709] PHICS can also induce neo-phosphorylations that are not observed in native cellular environment9’ and these phosphorylation can also alter protein structure and function,10 evoke an immune response,11 12 or affect the protein’s interaction with other biomolecules, particularly with RNA/DNA that have a negatively-charged backbone.13’14 For example, Applicants found a dimer of ABL binder (i.e., Homo-PHICS, Fig. 35A) induced phosphorylation at Tyr253 on BCR-ABL in the ATP pocket (Fig. 35B, C), leading to inhibition of BCR-ABL and death of CML cells (Fig. 35D) even those with mutations that are resistant to known drug imatinib (Fig. 35E).
[0710] The inability to harness the widely available kinase inhibitor to generate PHICS has greatly limited the technology and its applications. Furthermore, to demonstrate the utility of PHICS, Applicants have chosen oncogenic KRAS as the target for multiple reasons. First, KRAS is a high-value therapeutic target for which inhibitors13 are emerging (e.g., MRTX849, AMG510, MRTX1 133), but so are resistance to these inhibitors14 and several studies suggest that resistance mechanisms of bifunctional molecules are different from traditional enzyme inhibitors. Second, by altering the electrostatic surface topology/folding, the neo-phosphorylation will interfere with the GTP binding/membrane translocation of KRAS (Fig. 35F). Applicants have identified ~23 Ser/Thr near/on the GTP binding pocket/polybasic region of KRAS that can be targeted, including Ser 17 that coordinates with Mg2- or Thr35 makes contacts with GTP.15 Third, KRAS mutants are known to be HLA displayed8 9 and neo-PTMs can enhance the immunogenicity of these neo- antigens. Finally, KRAS is heavily post-translationally modified and interacts with several proteins; neo-phosphorylations may perturb the induction of endogenous PTMs and protein- protein interactions, offering additional avenues to inhibit KRAS activity.
[0711] Aim 1. Development and application of PHICS using cysteine-based group transfer chemistry
[0712] A PHICS based on BTK inhibitors: Applicants developed23 PHICS from a kinase inhibitor in which a nucleophile (e g., cysteine) near the inhibitor-binding pocket can initiate a group transfer chemistry26'29 resulting in appending the target-protein binder to the kinase while releasing the inhibitor from the active site (Fig. 36A). The kinase binder in such cysteine-tagging PHICS can be derived from abundantly available acrylamide-based inhibitors, where the amide nitrogen is often aryl amine (1, Fig. 36B) or less frequently aliphatic amine (2, Fig. 36B). Using these BTK inhibitor scaffolds, Applicants synthesized alkyne-containing analogs 3 and 4 by installing the cleavable methacrylamide linker (Fig. 36B).
[0713] To confirm BTK labeling, HEK293T cells transiently expressing BTK were treated with alkyne-containing compounds 3 or 4, and subsequent click chemistry with dye Cy5-Ns in lysate showed BTK labelling in-gel fluorescence (Fig. 36C). Next, BRD4-BTK PHICS 5 (aryl amine scaffold) and 7 (aliphatic amine scaffold) wherein the BTK inhibitor scaffold is connected to BRD4 binder, CS')-JQ I . via cleavable methacrylamide linker were synthesized (Fig. 36B). To demonstrate that cleavable methacrylamides do not block ATP -binding pocket, Applicants used a reported assay based on Bioluminescence Resonance Energy Transfer (BRET) between a nanoluciferase (nanoLuc) and a fluorophore probe (tracer) that binds to the ATP pocket;30 a higher occupancy of this ATP pocket by the inhibitor will prevent the binding of tracer and lower the BRET signal (Fig. 36D). Observed BRET ratios demonstrated that BTK inhibitors 1 and 2 dramatically lower BRET signal, while PHICS 5 or 7 or their alkyne analogs 3 and 4 did not (Fig. 36E). In congruence with these findings, Applicants observed higher autophosphorylation of BTK with PHICS compounds compared to the parent inhibitors 1 or 2 (data not shown). Finally, Applicants synthesized inactive controls of PHICS 5 and 7 (i.e., 6 and 8, Fig. 35B) using (7?)-JQl, which is a poor binder of BRD4 and tested these controls alongside 5 and 7 for their ability to induce phosphorylation of a cytosolically localized BRD4 (lacks NLS) by BTK as described previously.2 As expected, much higher BRD4 phosphorylation was observed in the presence of 5 (Fig. 36F) or 7 (Fig. 36G) than that with inactive controls, 6 or 8 (Fig. 36F-G). Applicants also observed significantly higher levels of co-immunoprecipitated BTK -FLAG in 5 or 7-treated samples compared to inactive controls, 6 or 7, suggesting ternary proximity induction by PHICS.

Synthesis and evaluation of cysteine-tarseting PHICS for diverse kinases: To demonstrate generalizability and leveraging several known acrylamide-based kinase inhibitors, Applicants synthesized PHICS for a diverse set of kinases (FIG. 89, Fig. 37) that differ in specificity (i.e., Ser/Thr vs. Tyr), cellular localization [e.g., cytosolic (cyt), nuclear (nuc), plasma membrane (mem), or endoplasmic reticulum (ER)], are overexpressed in diverse diseases, and phosphorylate diverse sequences. For example, FGFR phosphorylates pYxxQ motifs while BMX affects pYpY. Similarly, CDK phosphorylates [S/T*]Px[K/R] while CK phosphorylates D/E-D/E- D/E-X-X-S/T-cp or pS/pT-X-X-S/T-cp. Also, Applicants have chosen acrylamide-based kinase inhibitors with diverse pKa (-5-12, shown in blue Fig. 37B, 37C) at the leaving nitrogen atom. Leaving amino groups with lower pKa (weaker bases) may not facilitate the abstraction of a proton from Cys thiol and will be a poor leaving group as opposed to amino groups with high pKa (strong bases). Applicants used previously reported inhibitors scaffolds for pan-FGFR31 14, FGFR415, ILK32 33, EGFR34 35, JAK336, TAK137, AKT38, JNK139, BMX40, CDK741, and CKD1242 to synthesize their alkyne analogs and subsequent click chemistry with azide to generate the PHICS molecules using BRD4 as model neosubstrate (Fig. 37A, 37D). Using Ac-Cys-OMe as nucleophile, Applicants have successfully demonstrated release of leaving group in vitro with alkyne-bearing compounds 9-22a with most aryl amines reacting slowly compared to aliphatic amines (data not shown). Furthermore, using BRD4 as the model substrate, Applicants demonstrated PHICS-induced phosphorylation in HEK293T cells using FGFR, ITK, and JAK3 as the kinase (Fig. 37E). Comfortingly, these phosphorylations were decreased when cells were treated with competitor JQ1 in excess with PHICS.
[0715] C.1.2. Experimental Plan. C.1.2.1. Biochemical and cellular target engagement of kinases. Alkyne-bearing inhibitor compounds (Fig. 37A, 37B, 37C) with the Cys targeting warhead will be incubated with the respective kinases and conjugation will be assessed using in- gel fluorescence. Briefly, upon Cys labeling of the protein, copper-catalyzed click chemistry will be performed with azide-Cy5 and the extent of labeling will be directly visualized on the SDS- PAGE gel. Intact mass spectrometry will determine whether the conjugated protein formed an addition or elimination adduct with the compounds. Once the eliminated adduct mass is confirmed for the kinase, conjugated kinases will be tested for their activity using ADP-Glo™ assay,1 2 which measures the amount of ADP produced from the kinase reaction. Following these biochemical studies, Applicants will use the alkyne probe to evaluate the on-target and off-target labeling of various kinases in HEK293T as demonstrated in Fig. 36C and we will assess the inhibitor occupancy of ATP pocket using NanoBRET assay. These studies will provide quantitative data on kinase’s labeling efficiency and inhibition by alkyne compounds.
[0716] C.1.2.2. Cellular validation of PHICS using cytosolic BRD4 as neosubstrate. After the aforementioned studies, Applicants will focus on kinases with the highest labeling efficiency and lowest inhibition and generate BRD4 PHICS that will be tested in HEK293T cells as described in Fig. 36F-36G. Cells will be treated with active or inactive PHICS for ~2 hrs and phosphorylation of the BRD4 will be monitored after immunoprecipitation, followed by immunoblotting with phosphor-S/T/Y antibodies. Co-immunoprecipitation of the kinase and the target in the presence of PHICS (IQ1 can be used as a competitor) will be attempted to confirm the complex formation. [0717] C.1.2.3. Phosphorylation of KRAS and binary complex modeling. The BRD4 PHICS studies will identify kinases and ligands for KRAS G12D phosphorylation and examination of the effects of such phosphorylation on neoepitope display and downstream signaling. For the kinases ligands that successfully phosphorylate BRD4 above, we will synthesize PHICS using KRAS G12D inhibitor (Fig. 37D). Subsequently, we will perform ADP-Glo assay to determine target protein phosphorylation, leveraging the high-throughput nature of this assay. Next, Applicants will use previously reported AlphaScreen assay1-2 that quantifies complex formation in the presence of PHICS to identify the most optimal molecules for complex formation between kinase and target protein. The catalytic nature of these active PHICS molecules will be assessed by ADP-Glo assay. Western blotting will be performed to determine the phosphorylation of the target protein in the presence of PHICS (and KRAS binder as a competitor for control) using phospho-S/T/Y, or substrate motif antibodies. Mass spectrometry studies will be performed in the presence of PHICS to identify the neo-phosphorylation sites on KRAS G12D.
[0718] The protein-protein interactions between the kinase and KRAS G12D can enhance or attenuate the activity of PHICS molecules. Even if the binding affinities of the individual components comprising PHICS are very high, if the enforced orientation is incorrect then a productive complex will not be formed, and phosphorylation will not occur effectively. Applicants can alter the identity of the kinase/KRAS binder, linker attachment sites, length and identity of the linkers, and exit vectors — how the linker exits the protein — to design PHICS that can promote cooperativity (FIG. 38). To determine the nature of cooperativity, we will model the equilibria between the labeled kinase and KRAS. There are two systems of equilibria, non-cooperative equilibria, and cooperative equilibria. In non-cooperative equilibria (a = 1), the terminal bodies (kinase and KRAS) are unable to interact with each other. In the cooperative equilibria, the interaction between these bodies is either enhance (termed positive cooperativity, a > 1) or diminish (termed negative cooperativity, a < 1).
[0719] C.1.2.4. Proteomic studies for off-target identification and HLA-peptidome analysis: Following the identification of optimum KRAS PHICS, Applicants will identify the off-target phosphorylation of not only the non-target proteins in cells but also on phosphorylation sites within the target protein that do not match the kinase substrate motif. Here, Applicants will use SILAC/TMT-based global phosphoproteomics where a given PHICS is incubated with “heavy,” 13C, 15N- bearing arginine and lysine residues, labelled 293T cells and compared to “light,” naturally abundant isotope, labelled cells treated with unjointed congeners. Changes in global phosphorylation levels of proteins will be monitored to determine PHICS specificity.44 [0720] Applicants will follow the published protocol46 47 that identify HLA-associated phosphopeptides to analyze the neo-phosphorylation induced by PHICS. Briefly, phosphopeptides generated from proteolysis of aberrantly phosphorylated KRAS are loaded onto HLA class I molecules. HLA-associated peptide complexes are then shuttled to the cell surface and displayed to the immune system to elicit a specific cytotoxic T cell response. Here, FHIOSE cells will be stably transfected with soluble HLA (sHLA)-A*0201 construct with a VLDLr sequence as a downstream purification tag. Subsequently, cells will be incubated with PHICS and the sHLA/peptide complexes will be extracted using an immunoaffinity column coupled with anti- VLDLr antibody. Upon phosphopeptide-enrichment, samples will be subjected to MS/MS to identify their sequence.
[0721] Aim 2. Development and application of PHICS using lysine-based group transfer chemistry.
[0722] C.2.1. Preliminary studies. C.2.1.1. Development of optimum linker for lysine reactivity: Most of Lys targeting group transfer linkers suffer from poor reaction rates, lack of stability/selectivity, and bulky nature. A-acyl-A-alkyl sulfonamides (NASA) have recently gained interest as covalent warheads for lysine targeting due to their fast reaction rates towards lysine (k ~ 104 M'1 s'1)48’49 Despite these promising attributes, NASA is bulky (unfit to be used as a linker for bifunctional molecules that are already large), hydrolyzes rapidly (tin ~ 5 h in PBS), and lack tunable analogs. Guided by physical organic chemistry, Applicants rationally designed NASA analogs with a small footprint, higher stability, and tunable reactivity. The NASA warheads follow a general structural motif as described in Fig. 39A. Traditionally Ri is a phenyl ring that in original reports served as a convenient handle for attachment to a solid phase resin50. Replacement of this ring with short aliphatic groups did not affect its reactivity towards lysine (compare 19 and 20 in Fig. 39B), permitting significant size reduction without loss of reactivity. The electrophilicity of the A-acyl group depends on the electron-withdrawing properties of the A-alkyl group (— R2), allowing fine-tuning of amine reactivity and hydrolytic stability. Applicants synthesized a series of NASA derivatives (Fig. 39B) and identified the — CH2CF3 group as a superior alternative to the typically used — CH2CN by providing comparable rates towards aminolysis (compare compounds 15 and 20 in Fig. 39B) accompanied by a 5-fold decrease of hydrolysis rates (Fig. 39C). These studies also provided analogs to fine-tune reactivity (Fig. 39B) and effective molarity. [0723] C.2.1.2. Synthesis and evaluation of lysine-targeting PHICS. Applicants designed and synthesized lysine targeting probes based on a variety of previously described high-affinity, allosteric kinase inhibitors (Ad < 100 nM) (Fig. 40A) targeting LIMK51, MEK1/252, RIP153, EGFR54, IRE155 and CDK256. Crucial selection criteria for the parent kinase inhibitors were the availability of crystallographic data, which allowed for the rational incorporation of NASA linkers proximal to lysine residues. In addition, the inhibitors chosen for the lysine targeting PHICS bind to allosteric sites of the kinases, diversifying the potential neo-phosphopeptides that can be accessed. These molecules were used for the synthesis of Lys targeting-PHICS similarly to the Cys targeting ones by combining the alkyne probes described in Fig. 40A with the target binder azides, via click chemistry (Fig. 40B). In addition, the alkyne components were used to demonstrate the ability of the NASA kinase inhibitors to sufficiently label the corresponding kinases in in-vitro assays. Treatment of purified proteins with the appropriate probes under proximity-driven reactivity conditions (i.e., < 10 μM) followed by click chemistry with dye Cy5- N3 demonstrated fluorescence labelling with probes over control treatment (Fig. 40C), validating our rational design approach and confirming presence of reactive Lys.
[0724] C.2.2. Experimental Plan. C.2.2.2. Biochemical and cellular target engagement of kinases (same as in C.l.2.2). The initial design of PHICS molecules is based on high-affinity kinase inhibitors (Ad < 100 nM). Although this is desirable from a labelling perspective, subsequent kinase inhibition can reduce PHICS efficacy. Applicants will systematically study the impact of residence time and PHICS efficacy (Fig. 40D). For example, Sunitinib and Bosutinib (colored blue in Fig. 40A) can bind to Ser/Thr and Tyr kinases with varying residence time (t).57 Sunitinib for example, can bind to kinases with residence time ranging from seconds to minutes [t = 5 seconds for CHK1, t = 10 seconds for IRAK4, t = 37 seconds for ITK, t= 2.9 minutes VEGFR], [0725] The size of some of the proposed PHICS molecules can potentially limit their cell permeability. However, Applicants would like to point out that their weight and clogP values are close to those of successful cell-permeable PROTACs and such permeability could be arising from receptor-mediated transport as has been demonstrated recently for many molecules.58'60 Applicants will adjust polarity by changing the nature of the linkers (alkyl vs. PEG, A-methylation of amide bonds), to assemble final PHICS molecules inside the cell via metal-free click-chemistry.61 [0726] The phosphorylation stoichiometry must be relatively high to elicit an immune response. The usage of pan-targeting kinase inhibitors in our PHICS design will circumvent this concern. A significant challenge in selectively detecting neo-phosphopeptides on HLA is the off- target phosphorylation events arising from kinase inhibitor moiety present in PHICS. To overcome this, Applicants will do time and dose titrations to determine an acute treatment of PHICS to avoid off-target effects. The dynamic nature of phosphorylation and dephosphorylation may limit the number of occurrences of neo-phosphorylation and neo-phosphopeptides on HLA display. As such, Applicants will use phosphatase inhibitors treated cells.

Example 3 - Proximity-Inducing Molecules with Cleavable Linker for Extracellular and
Intracellular Targets
Introduction
[0728] Bifunctional molecules have emerged as powerful and novel therapeutic modalities due to their ability to enhance existing protein-protein interactions (PPIs) or promote neo-PPIs. One particularly interesting category of this class are bifunctional molecules which induce post translational modifications on a protein of interest (POI). Current design of such bifunctional molecules consists of a three-component “dumbbell-like” structure. The two protein binders are connected via a linker of appropriate length (FIG. 91A). This design has been successfully applied for PTM induction using proteolysis targeting chimeras (PROTACs)1, phosphorylation inducing chimeras (PHICS)2, phosphatase recruitment chimeras (PHORCs)3, deubiquitinase-targeting chimeras (DUBTACs)4 etc. Biological evaluation of these bifunctional molecules reveals that perturbation of the PTM homeostasis results in phenotypic alterations of therapeutic relevancy. This is possible because the bifunctional molecule “forces” increased effective molarity between the POI and the PTM writer/eraser. For example, PROTACs which are the most widely studied group of bifunctional molecules, increase ubiquitinalation of the targeted protein leading to its degradation via the proteasome pathway, while DUBTACs have the opposite effect. On the other hand, PHICS induce phosphorylation on target protein altering its charge state, with detrimental effects on protein structure and function. Interestingly the corresponding eraser PHORCs can induce similar affects.
[0729] It is apparent from the current design of such molecules that on the site of the PTM writer/eraser the use of high-affinity, non-inhibitory and allosteric binders is required (FIG. 91B). Among the known binders few molecules have all desired characteristics limiting the available chemical matter can be utilized as well as the PTM writer/erasers can be targeted. In addition, current dumbbell design paradigm uses non-covalent molecules which reduces its applications. Covalency can increase binding potency, prolong ternary complex formation, and expand the applications of bifunctional molecules. Recently, generation of MHC-restricted neoantigens utilizing covalent chemistry has gained increased interest5, with application of bifunctional molecules on such systems yet to be explored.
[0730] Applicants’ laboratory has developed a new design paradigm which bypasses the limitations of current bifunctional design (FIG. 91C). It utilizes thiol mediated group-transfer chemistry for the generation of bifunctional molecules which will form ternary complexes in a two-step pathway. Initially, a covalent binder occupies the active site of the PTM writer/eraser facilitating Michael addition, followed by a retro-aza-Michael which releases the binder (this chemistry was originally reported by AstraZeneca6 (in 2013) without further investigation). The released non-covalent compound typically has reduced affinity, which in combination with the high abundance of the natural substrate results in its displacement from the active site permitting PTM induction/removal on the target protein. This technology is complementary to the current bifunctional design because it allows the utilization of allosteric or active site inhibitors, which represent most chemical matter on the PTM space. In addition, the technology, allows for the generation of bifunctional molecules with extracellular applications.
Results and Discussion
Design and synthesis of FGFR-recruitins chimeras.
[0731] Given the key role played by Fibroblast growth factor receptor (FGFR) in cellular signaling for cell growth, proliferation and, division and, widespread occurrence of aberrant FGFR signaling in different type of cancers involving different isoforms (namely FGFR1-4), Applicants chose to three FGFR covalent inhibitors (1, 2, 3) namely Fisogatinib (FGFR4), Futibatinib and PRN1317 (pan-FGFR) and synthesized the corresponding methacrylamide compounds containing alkyne handle (4, 5, 6) (FIG. 92A). To validate the proposed addition elimination reactivity of the methacrylamide warhead with cysteine, Applicants studied the reactivity of the compounds 4, 5 and 6 with N- Acetyl -cysteine methyl ester at room temperature in PBS buffer (pH 7.4) in a time dependent manner (FIG. 92B). Applicants observed the decay of alkyne with subsequent rise in the concentration of the corresponding non-covalent kinase binder (eliminated amine) (FIG. 92C). Demonstration of phosphorylation on proof-of-concept target BRD4.
[0732] All four isoforms of FGFRs have conserved kinase domains with 74-92% sequence identity. Several covalent inhibitors were developed to target cysteines in the FGFRs, most of them are Pan-FGFR inhibitors targeting P-loop cysteine of the kinase domain and some exploit the presence of unique Cysteine residue in the hinge region of FGFR4 kinase. Three covalent inhibitors in the clinical trials were selected for the designing of PHICS molecules: FGFR4 selective Fisogatinib, Pan-FGFR inhibitors Futibatinib and PRN1317. The inhibitory potential of these molecules is dictated by their covalency and permanent occupancy of the ATP binding pocket. Applicants have used group transfer chemistry to label the protein with the target binder. For designing the PHICS with cysteine group transfer chemistry (CGT-PHICS), inhibitor scaffolds were exploited for their selectivity to the FGFR kinases and group transfer chemistry to label specific cysteine with the target protein binder leaving behind the ineffective non-covalent inhibitor in the ATP binding pocket of the kinase. BRD4 binder (5)-JQl was conjugated with the alkyne compounds by copper catalyzed azide-alkyne click reaction (CuAAC) to generate CGT- PHICS 7, 8 and 9 (FIG. 93 A). Cellular labeling of FGFR4 protein was confirmed by the In-gel fluorescence and Intact-mass spectrometry (Supp. Figures X and Y). Nano-BRET assay was performed to determine the occupancy of the released non-covalent molecules in the ATP binding pocket. Nano-BRET assay measures the signal for the binding of fluorophore conjugated tracer molecule to the ATP binding pocket of the kinase, which fluoresces upon excitation from the luminescence signal from the FGFR-nanoluc. In the nano-BRET assay, HEK293T cells were transfected with FGFR4-nanoluc and treated with the covalent (1, 2 and 3), non-Covalent (4A, 5A and 6A) and CGT-PHICS (7, 8 and 9). A massive drop in the occupancy was observed in the case of the CGT-PHICS (7, 8 and 9) as compared to the covalent inhibitors (1, 2 and 3) (FIG. 93B, 93C and 93D). The FGFR4 pocket was fully occupied at very low concentration by the covalent (1, 2 and 3) molecules, whereas lower occupancy by was observed for the CGT-PHICS (7, 8 and 9) even at very high concentrations (FIG. 93B, 93C and 93D). Interestingly, the non-covalent molecule 6A showed higher occupancy as compared to its cognate PHICS 9. These observations point toward the fact that CGT-PHICS (7, 8 and 9) upon labeling do not effectively occupy the ATP pocket after the release of non-covalent inhibitor, hence could lose its potency to inhibit the kinase. To test the hypothesis, PHICS molecules designed by conjugating the FGFR inhibitors with JQ1 were used to target BRD4 proteins for phosphorylation. The phosphorylation on BRD4 was observed in the presence of CGT-PHICS (7 and 8) using FGFR4 (FIG. 93E and 93F) and with its variant FGFR2 using CGT-PHICS 8 (FIG. 93G), whereas CGT-PHICS 9 doesn’t induce any phosphorylation on BRD4 in HEK293T cells (FIG. 93H). The FGFR phosphorylations on BRD4 in the presence of PHICS also corroborated with the occupancy data and rate constant, where CGT- PHICS (7 and 8) and methacrylamide (4 and 5) showed lower occupancy and higher rate constant as compared with CGT-PHICS 9 and 6, respectively (FIGS. 92C, 93B, 93 C and 93D). Overall, PHICS based group transfers on FGFRs suggest that FGFRs can tolerate huge modifications on the hinge Cys-552 (FGFR4) or the P-loop Cys-447 (FGFR4 and FGFR2) and the released non- covalent inhibitor in the ATP binding pocket will be replaced by the presence of a high concentration of ATP in the cell keeping the kinase active for target protein phosphorylation.
Functional activity of FGFR-recruitins chimeras.
[0733] RTKs regulate the proliferation, differentiation, and metabolism of cells by inducing downstream signaling in response to external factors such as Fibroblast Growth Factors (FGFs). FGFs binds extracellular domains of FGFRs and induce the dimerization resulting in cross- phosphorylation and downstream signaling. Chemical inducer of dimerization (CID) molecule FK1012 (a dimeric FKPB binder) was used intracellularly for the dimerization of RTKs fused with FKBP to induce signaling.
[0734] However, these systems required artificial integration of the FKBP gene on the target gene for spatial-temporal control. Since the group transfer chemistry on several kinases were successfully performed without affecting their activity. Applicants have designed dimeric PHICS (dPHICS) molecules for inducing dimerization and phosphorylation of FGFR kinases subsequently leading to the induction of downstream pathways (FIG. 94A). Among several advantages, as compared to previous techniques (FKBP), genetic modification of the target gene was not required. In a paradox, inhibitors were used for designing PHICS and downstream signaling. FGFR signaling complex may lead to the activation of four signaling branches PI3K/AKT, PLCy/DAG/PKC, RAS/RAF/MAPK, and GSK3p/[3-catenin, which are involved in proliferation, antiapoptotic, angiogenesis and drug resistance. dPHICS equipped with group transfer chemistry were synthesized by joining either two FGFR4 selective Fisogatinib or Pan- FGFR inhibitor Futibatinib (FIG. 94B). HEK293T cells were treated with the PHICS 10 and PHICS 12 molecules for 90 minutes and the cell lysate was probed for ERK phosphorylation. A dose dependent increase in the pERK was observed for both PHICS 11 and 12, which gives a maximum pERK signal at 250 nM and turns inhibitory at 500 nM (FIG. 94C). This suggests that dPHICS can be used for the tunable intracellular activation of the FGFR downstream signaling.
Generalization to other kinases.
[0735] Having established the cysteine group transfer chemistry with FGFR, Applicants wanted to check the generality of group transfer by targeting cysteine of other kinases. Applicants chose covalent kinase inhibitors of Janus kinase 3 (JAK3) (12), IL2 inducible T cell kinase (ITK) (18 and 19) and Epidermal growth factor receptor (EGFR) (20 and 21) as the target and prepared corresponding methacrylamide compounds containing alkyne handle (17-21) and (S)-JQ1 clicked PHICS (22-26) (FIG. 95A). Similar to the FGFR compounds, the methacrylamide compounds (17- 21) showed similar reactivity with N-Acetyl-cysteine methyl ester (FIG. 95B). A nano-BRET assay was performed on JAK3 and ITK to determine the occupancy of covalent (12, 13 and 14), non-Covalent (12A, 13A and 14A) and CGT- PHICS (22, 23 and 24). CGT -PHICS showed the lowest occupancy of the ATP binding pockets of the JAK3 and ITK as compared with the most obvious covalent and even non-covalent inhibitors (FIG. 95C, 95D and 95E). All the fS')-JQ l clicked PHICS were active in inducing significant levels of BRD4 phosphorylation as compared to DMSO control. Competition with (+) JQ1 at a 1 :4 ratio of the PHICS reduced the BRD4 phosphorylation, confirming CGT-PHICS-dependent phosphorylations on BRD4 (FIG. 95F, 95G, 95H, 951 and 95J).
