FIELD OF THE INVENTION
4 PCT/US2019/050114 [0004] The description provides bifunctional compounds comprising a target protein binding moiety and an E3 ubiquitin ligase binding moiety, and associated methods of use. The bifunctional compounds are useful as modulators of targeted ubiquitination, especially with respect to Rapidly Accelerated Fibrosarcoma (RAF) proteins, which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure.
BACKGROUND
BACKGROUND
[0005] Most small molecule drugs bind enzymes or receptors in tight and well-defined pockets. On the other hand, protein-protein interactions are notoriously difficult to target using small molecules due to their large contact surfaces and the shallow grooves or flat interfaces involved. E3 ubiquitin ligases (of which hundreds are known in humans) confer substrate specificity for ubiquitination, and therefore, are more attractive therapeutic targets than general proteasome inhibitors due to their specificity for certain protein substrates.
The development of ligands of E3 ligases has proven challenging, in part due to the fact that they must disrupt protein-protein interactions. However, recent developments have provided specific ligands which bind to these ligases. For example, since the discovery of nutlins, the first small molecule E3 ligase inhibitors, additional compounds have been reported that target E3 ligases but the field remains underdeveloped. For example, since the discovery of Nutlins, the first small molecule E3 ligase mouse double minute 2 homolog (MDM2) inhibitors, additional compounds have been reported that target MDM2 (i.e., human double minute 2 or HDM2) E3 ligases (J.
Di, et al.
Current Cancer Drug Targets (2011), 11(8), 987-994).

[0006] Tumor suppressor gene p53 plays an important role in cell growth arrest and apoptosis in response to DNA damage or stress (A. Vazquez, et al. Nat. Rev.
Drug. Dis. (2008),
Drug. Dis. (2008),
7, 979-982), and inactivation of p53 has been suggested as one of the major pathway for tumor cell survival (A. J. Levine, et al. Nature (2000), 408, 307-310). In cancer patients, about 50%
were found with p53 mutation (M. Hollstein, et al. Science (1991), 233, 49-53), while patients with wild type p53 were often found p53 down regulation by MDM2 through the protein-protein interaction of p53 and MDM2 (P. Chene, et al. Nat. Rev. Cancer (2003), 3, 102-109). Under normal cell condition without oncogenic stress signal, MDM2 keeps p53 at low concentration. In response to DNA damage or cellular stress, p53 level increases, and that also causes increase in MDM2 due to the feedback loop from p53/MDM2 auto regulatory system. In other words, p53 regulates MDM2 at the transcription level, and MDM2 regulates p53 at its activity level (A. J.
Levine, et al. Genes Dev. (1993) 7, 1126-1132).
[0007] Several mechanisms can explain p53 down regulation by MDM2. First, MDM2 binds to N-terminal domain of p53 and blocks expression of p53-responsive genes (J.
Momand, et al.
Cell (1992), 69, 1237-1245). Second, MDM2 shuttles p53 from nucleus to cytoplasm to facilitate proteolytic degradation (J. Roth, et al. EMBO J. (1998), 17, 554-564). Lastly, MDM2 carries intrinsic E3 ligase activity of conjugating ubiquitin to p53 for degradation through ubiquitin-dependent 26s proteasome system (UPS) (Y. Haupt, et al. Nature (1997) 387, 296-299). As such, because MDM2 functions as E3 ligase, recruiting MDM2 to a disease causing protein and effectuating its ubiquitination and degradation is an approach of high interest for drug discovery.

[0008] One E3 ligase with exciting therapeutic potential is the von Hippel-Lindau (VHL) tumor suppressor, the substrate recognition subunit of the E3 ligase complex VCB, which also consists of elongins B and C, Cul2 and Rbx 1 . The primary substrate of VHL is Hypoxia Inducible Factor la (HIF-1a), a transcription factor that upregulates genes such as the pro-angiogenic growth factor VEGF and the red blood cell inducing cytokine erythropoietin in response to low oxygen levels. The first small molecule ligands of Von Hippel Lindau (VHL) to the substrate recognition subunit of the E3 ligase were generated, and crystal structures were obtained confirming that the compound mimics the binding mode of the transcription factor HIF-1 a, the major substrate of VHL.
[0009] Cereblon is a protein that in humans is encoded by the CRBN gene.
CRBN orthologs are highly conserved from plants to humans, which underscores its physiological importance.
Cereblon forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A), and regulator of cullins 1 (ROC1). This complex ubiquitinates a number of other proteins. Through a mechanism which has not been completely elucidated, cereblon ubquitination of target proteins results in increased levels of fibroblast growth factor 8 (FGF8) and fibroblast growth factor 10 (FGF10). FGF8 in turn regulates a number of developmental processes, such as limb and auditory vesicle formation. The net result is that this ubiquitin ligase complex is important for limb outgrowth in embryos. In the absence of cereblon, DDB1 forms a complex with DDB2 that functions as a DNA damage-binding protein.

[0010] Inhibitors of Apotosis Proteins (IAPs) are a protein family involved in suppressing apoptosis, i.e. cell death. The human TAP family includes 8 members, and numerous other organisms contain TAP homologs. IAPs contain an E3 ligase specific domain and baculoviral TAP repeat (BIR) domains that recognize substrates, and promote their ubiquitination. IAPs promote ubiquitination and can directly bind and inhibit caspases. Caspases are proteases (e.g.
caspase-3, caspase-7 and caspace-9) that implement apoptosis. As such, through the binding of caspases, IAPs inhibit cell death. However, pro-apoptotic stimuli can result in the release of mitochondrial proteins DIABLO (also known as second mitrochondria-derived activator of caspases or SMAC) and HTRA2 (also known as Omi). Binding of DIABLO and HTRA2 appears to block TAP activity.

NIL-IAP, Bruce, and survivin. The first four amino acids (AVPI) of mature SMAC

[0012] Bifunctional compounds such as those that are described in U.S.
Patent Application Publications 2015-0291562 and 2014-0356322 (incorporated herein by reference), function to recruit endogenous proteins to an E3 ubiquiuin ligase for degradation. In particular, the publications describe bifunctional or proteolysis targeting chimeric (PROTAC) compounds, which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, which are then degraded and/or otherwise inhibited by the bifunctional compounds.

[0013] An ongoing need exists in the art for effective treatments for disease associated with overexpression or aggregation of Rapidly Accelerated Fibrosarcoma (RAF), or the overactivation of RAF (such as constitutively active RAF). For example, current BRaf inhibitors (such as, vemurafenib and dabrafenib) may target V600 mutant BRaf. Thus, a need exists for diseases or disorders (such as, melanoma, lung cancer, pancreatic cancer, and/or colorectal cancers) that have different BRaf mutations that are insensitive to currently marketed agents.
Furthermore, resistance mutations can emerge in response to BRaf/MEK inhibitor therapy. For example, the p61 splice variant can emerge in melanoma patients treated with BRaf/MEK
inhibitor therapy, which leaves these patients with no clinical options.
Currently marketed agents also bind to and cause paradoxical activation of wild-type BRaf, which results in clinical complications. In addition, the family of hypoactive Class III BRaf mutants that signal through heterodimerization with CRaf, constitute 40% of BRaf mutations in non-small cell lung cancer (NSCLC), and also appear sporadically across other cancers, cannot be targeted with any currently approved or clinical-stage BRaf inhibitors. Class I BRAF mutants (V600E, V600K, V600D) have high kinase activity, are Ras and dimerization independent, and are sensitive to vemuragenib. Class II BRAF mutants has high to intermediate kinase activity, are Ras-independent and dimerization dependent, and are insensitive to vemurafenib.
Class III BRAF
mutatns have lot to no kinase activity, are Ras and dimerization dependent, and are insensitive to vemurafenib.
Furthermore, resistance mutations can emerge in response to BRaf/MEK inhibitor therapy. For example, the p61 splice variant can emerge in melanoma patients treated with BRaf/MEK

Class III BRAF
mutatns have lot to no kinase activity, are Ras and dimerization dependent, and are insensitive to vemurafenib.
[0014] Thus, non-specific effects and the inability to target and modulate RAF, remain an obstacle to the development of effective treatments. As such, small-molecule therapeutic agents that effectively targets RAF (e.g., effectively inhibiting and/or degrading mutant forms of BRaf, while sparing wild-type BRaf) and that leverage or potentiate VHL's, cereblon's, MDM2's, and IAPs' substrate specificity would be very useful.
SUMMARY
SUMMARY
[0015] The present disclosure describes bifunctional compounds which function to recruit endogenous proteins to an E3 ubiquitin ligase for degradation, and methods of using the same.
In particular, the present disclosure provides bifunctional or proteolysis targeting chimeric (PROTAC) compounds, which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, which are then degraded and/or otherwise inhibited by the bifunctional compounds as described herein. An advantage of the compounds provided herein is that a broad range of pharmacological activities is possible, consistent with the degradation/inhibition of targeted polypeptides from virtually any protein class or family. In addition, the description provides methods of using an effective amount of the compounds as described herein for the treatment or amelioration of a disease condition, such as cancer (e.g., renal cell carcinoma, pancreatic cancer, colorectal cancer, lung cancer, ovarian cancer, thyroid cancer, pilocytic astrocytoma, prostate cancer, gastric cancer, hepatocellular carcinoma, and melanoma), cardiofaciocutaneous syndrome, neurofibromatosis type 1, Costello syndrome, Noonan Syndrome, LEOPARD (Lentigo, Electrocardiographic abnormalities, Ocular hypertelorism, Pulmonary stenosis, Abnormal genitalia, Retarded growth, Deafness) syndrome.
In particular, the present disclosure provides bifunctional or proteolysis targeting chimeric (PROTAC) compounds, which find utility as modulators of targeted ubiquitination of a variety of polypeptides and other proteins, which are then degraded and/or otherwise inhibited by the bifunctional compounds as described herein. An advantage of the compounds provided herein is that a broad range of pharmacological activities is possible, consistent with the degradation/inhibition of targeted polypeptides from virtually any protein class or family.

[0016] As such, in one aspect the disclosure provides bifunctional or PROTAC compounds, which comprise an E3 ubiquitin ligase binding moiety (i.e., a ligand for an E3 ubquitin ligase or "ULM" group), and a moiety that binds a target protein (i.e., a protein/polypeptide targeting ligand or "PTM" group) such that the target protein/polypeptide is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. In a preferred embodiment, the ULM (ubiquitination ligase modulator) can be Von Hippel-Lindau E3 ubiquitin ligase (VHL) binding moiety (VLM), or a cereblon E3 ubiquitin ligase binding moiety (CLM), or a mouse double miniute 2 homolog (MDM2) E3 ubiquitin ligase binding moiety (MLM), or an TAP E3 ubiquitin ligase binding moiety (i.e., a "ILM"). For example, the structure of the bifunctional compound can be depicted as:
PTM _________________________ ULM
PTM _________________________ ULM
[0017] The respective positions of the PTM and ULM moieties (e.g., VLM, CLM, MLM or ILM) as well as their number as illustrated herein is provided by way of example only and is not intended to limit the compounds in any way. As would be understood by the skilled artisan, the bifunctional compounds as described herein can be synthesized such that the number and position of the respective functional moieties can be varied as desired.
[0018] In certain embodiments, the bifunctional compound further comprises a chemical linker ("L"). In this example, the structure of the bifunctional compound can be depicted as:

DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0051] The following is a detailed description provided to aid those skilled in the art in practicing the present disclosure. Those of ordinary skill in the art may make modifications and variations in the embodiments described herein without departing from the spirit or scope of the present disclosure. All publications, patent applications, patents, figures and other references mentioned herein are expressly incorporated by reference in their entirety.
[0052] Presently described are compositions and methods that relate to the surprising and unexpected discovery that an E3 ubiquitin ligase protein (e.g., inhibitors of apoptosis proteins (TAP), a Von Hippel-Lindau E3 ubiquitin ligase (VHL), a cereblon E3 ubiquitin ligase, or a mouse double minute 2 homolog (MDM2) E3 ubiquitin ligase) ubiquitinates a target protein once it and the target protein are placed in proximity by a bifunctional or chimeric construct that binds the E3 ubiquitin ligase protein and the target protein. Accordingly the present disclosure provides such compounds and compositions comprising an E3 ubiquintin ligase binding moiety ("ULM") coupled to a protein target binding moiety ("PTM"), which result in the ubiquitination of a chosen target protein, which leads to degradation of the target protein by the proteasome (see Figure 1). The present disclosure also provides a library of compositions and the use thereof.
[0053] In certain aspects, the present disclosure provides compounds which comprise a ligand, e.g., a small molecule ligand (i.e., having a molecular weight of below 2,000, 1,000, 500, or 200 Daltons), which is capable of binding to a ubiquitin ligase, such as TAP, VHL, MDM2, or cereblon. The compounds also comprise a moiety that is capable of binding to target protein, in such a way that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and/or inhibition) of that protein. Small molecule can mean, in addition to the above, that the molecule is non-peptidyl, that is, it is not generally considered a peptide, e.g., comprises fewer than 4, 3, or 2 amino acids. In accordance with the present description, the PTM, ULM or PROTAC molecule can be a small molecule.
[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description is for describing particular embodiments only and is not intended to be limiting of the disclosure.
[0055] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise (such as in the case of a group containing a number of carbon atoms in which case each carbon atom number falling within the range is provided), between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the disclosure.
[0056] The following terms are used to describe the present disclosure. In instances where a term is not specifically defined herein, that term is given an art-recognized meaning by those of ordinary skill applying that term in context to its use in describing the present disclosure.
[0057] The articles "a" and "an" as used herein and in the appended claims are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, "an element" means one element or more than one element.
[0058] The phrase "and/or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.
Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A
only (optionally including elements other than B); in another embodiment, to B
only (optionally including elements other than A); in yet another embodiment, to both A and B
(optionally including other elements); etc.
Multiple elements listed with "and/or" should be construed in the same fashion, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the "and/or" clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and/or B", when used in conjunction with open-ended language such as "comprising" can refer, in one embodiment, to A
only (optionally including elements other than B); in another embodiment, to B
only (optionally including elements other than A); in yet another embodiment, to both A and B
(optionally including other elements); etc.
[0059] As used herein in the specification and in the claims, "or" should be understood to have the same meaning as "and/or" as defined above. For example, when separating items in a list, "or" or "and/or" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as "only one of' or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of a number or list of elements. In general, the term "or" as used herein shall only be interpreted as indicating exclusive alternatives (i.e., "one or the other but not both") when preceded by terms of exclusivity, such as "either," "one of," "only one of," or "exactly one of."
[0060] In the claims, as well as in the specification above, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving,"
"holding,"
"composed of," and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases "consisting of and "consisting essentially of shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
"holding,"
"composed of," and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases "consisting of and "consisting essentially of shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
[0061] As used herein in the specification and in the claims, the phrase "at least one," in reference to a list of one or more elements, should be understood to mean at least one element selected from anyone or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those elements specifically identified. Thus, as a nonlimiting example, "at least one of A and B" (or, equivalently, "at least one of A or B," or, equivalently "at least one of A
and/or B") can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A);
in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
and/or B") can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A);
in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
[0062] It should also be understood that, in certain methods described herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited unless the context indicates otherwise.
[0063] The terms "co-administration" and "co-administering" or "combination therapy" refer to both concurrent administration (administration of two or more therapeutic agents at the same time) and time varied administration (administration of one or more therapeutic agents at a time different from that of the administration of an additional therapeutic agent or agents), as long as the therapeutic agents are present in the patient to some extent, preferably at effective amounts, at the same time. In certain preferred aspects, one or more of the present compounds described herein, are coadministered in combination with at least one additional bioactive agent, especially including an anticancer agent. In particularly preferred aspects, the co-administration of compounds results in synergistic activity and/or therapy, including anticancer activity.
[0064] The term "compound", as used herein, unless otherwise indicated, refers to any specific chemical compound disclosed herein and includes tautomers, regioisomers, geometric isomers, and where applicable, stereoisomers, including optical isomers (enantiomers) and other stereoisomers (diastereomers) thereof, as well as pharmaceutically acceptable salts and derivatives, including prodrug and/or deuterated forms thereof where applicable, in context.
Deuterated small molecules contemplated are those in which one or more of the hydrogen atoms contained in the drug molecule have been replaced by deuterium.
Deuterated small molecules contemplated are those in which one or more of the hydrogen atoms contained in the drug molecule have been replaced by deuterium.
[0065] Within its use in context, the term compound generally refers to a single compound, but also may include other compounds such as stereoisomers, regioisomers and/or optical isomers (including racemic mixtures) as well as specific enantiomers or enantiomerically enriched mixtures of disclosed compounds. The term also refers, in context to prodrug forms of compounds which have been modified to facilitate the administration and delivery of compounds to a site of activity. It is noted that in describing the present compounds, numerous substituents and variables associated with same, among others, are described. It is understood by those of ordinary skill that molecules which are described herein are stable compounds as generally described hereunder. When the bond is shown, both a double bond and single bond are represented or understood within the context of the compound shown and well-known rules for valence interactions.
[0066] The term "ubiquitin ligase" refers to a family of proteins that facilitate the transfer of ubiquitin to a specific substrate protein, targeting the substrate protein for degradation. For example, TAP an E3 ubiquitin ligase protein that alone or in combination with an E2 ubiquitin-conjugating enzyme causes the attachment of ubiquitin to a lysine on a target protein, and subsequently targets the specific protein substrates for degradation by the proteasome. Thus, E3 ubiquitin ligase alone or in complex with an E2 ubiquitin conjugating enzyme is responsible for the transfer of ubiquitin to targeted proteins. In general, the ubiquitin ligase is involved in polyubiquitination such that a second ubiquitin is attached to the first; a third is attached to the second, and so forth. Polyubiquitination marks proteins for degradation by the proteasome.
However, there are some ubiquitination events that are limited to mono-ubiquitination, in which only a single ubiquitin is added by the ubiquitin ligase to a substrate molecule. Mono-ubiquitinated proteins are not targeted to the proteasome for degradation, but may instead be altered in their cellular location or function, for example, via binding other proteins that have domains capable of binding ubiquitin. Further complicating matters, different lysines on ubiquitin can be targeted by an E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin, which is recognized by the proteasome.

This is the lysine used to make polyubiquitin, which is recognized by the proteasome.
[0067] The term "patient" or "subject" is used throughout the specification to describe an animal, preferably a human or a domesticated animal, to whom treatment, including prophylactic treatment, with the compositions according to the present disclosure is provided. For treatment of those infections, conditions or disease states which are specific for a specific animal such as a human patient, the term patient refers to that specific animal, including a domesticated animal such as a dog or cat or a farm animal such as a horse, cow, sheep, etc. In general, in the present disclosure, the term patient refers to a human patient unless otherwise stated or implied from the context of the use of the term.
[0068] The term "effective" is used to describe an amount of a compound, composition or component which, when used within the context of its intended use, effects an intended result.
The term effective subsumes all other effective amount or effective concentration terms, which are otherwise described or used in the present application.
The term effective subsumes all other effective amount or effective concentration terms, which are otherwise described or used in the present application.

Examples of nitrogen heterocycles and heteroaryls include, but are not limited to, pyrrole, imidazole, pyrazole, pyridine, pyrazine, pyrimidine, pyridazine, indolizine, isoindole, indole, indazole, purine, quinolizine, isoquinoline, quinoline, phthalazine, naphthylpyridine, quinoxaline, quinazoline, cinnoline, pteridine, carbazole, carboline, phenanthridine, acridine, phenanthroline, isothiazole, phenazine, isoxazole, phenoxazine, phenothiazine, imidazolidine, imidazoline, piperidine, piperazine, indoline, morpholino, piperidinyl, tetrahydrofuranyl, and the like as well as N-alkoxy-nitrogen containing heterocycles. The term "heterocyclic"' also includes bicyclic groups in which any of the heterocyclic rings is fused to a benzene ring or a cyclohexane ring or another heterocyclic ring (for example, indolyl, quinolyl, isoquinolyl, tetrahydroquinolyl, and the like).
[0097] The term "cycloalkyl" can mean but is in no way limited to univalent groups derived from monocyclic or polycyclic alkyl groups or cycloalkanes, as defnied herein, e.g., saturated monocyclic hydrocarbon groups having from three to twenty carbon atoms in the ring, including, but not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and the like.
The term "substituted cycloalkyl" can mean but is in no way limited to a monocyclic or polycyclic alkyl group and being substituted by one or more substituents, for example, amino, halogen, alkyl, substituted alkyl, carbyloxy, carbylmercapto, aryl, nitro, mercapto or sulfo, whereas these generic substituent groups have meanings which are identical with definitions of the corresponding groups as defined in this legend.
The term "substituted cycloalkyl" can mean but is in no way limited to a monocyclic or polycyclic alkyl group and being substituted by one or more substituents, for example, amino, halogen, alkyl, substituted alkyl, carbyloxy, carbylmercapto, aryl, nitro, mercapto or sulfo, whereas these generic substituent groups have meanings which are identical with definitions of the corresponding groups as defined in this legend.
[0098] "Heterocycloalkyl" refers to a monocyclic or polycyclic alkyl group in which at least one ring carbon atom of its cyclic structure being replaced with a heteroatom selected from the group consisting of N, 0, S or P. "Substituted heterocycloalkyl" refers to a monocyclic or polycyclic alkyl group in which at least one ring carbon atom of its cyclic structure being replaced with a heteroatom selected from the group consisting of N, 0, S or P and the group is containing one or more substituents selected from the group consisting of halogen, alkyl, substituted alkyl, carbyloxy, carbylmercapto, aryl, nitro, mercapto or sulfo, whereas these generic substituent group have meanings which are identical with definitions of the corresponding groups as defined in this legend.
[0099] The term "hydrocarbyl" shall mean a compound which contains carbon and hydrogen and which may be fully saturated, partially unsaturated or aromatic and includes aryl groups, alkyl groups, alkenyl groups and alkynyl groups.
[0100] The term "independently" is used herein to indicate that the variable, which is independently applied, varies independently from application to application.
[0101] The term "lower alkyl" refers to methyl, ethyl or propyl
[0102] The term "lower alkoxy" refers to methoxy, ethoxy or propoxy.
[0103] In any of the embodiments described herein, the W, X, Y, Z, G, G', R, R', R", Q1-Q4, and A, can independently be covalently coupled to a linker and/or a linker to which is attached one or more PTM, ULM, ILM or ILM' groups.

[0279] Although the ULM group and PTM group may be covalently linked to the linker group through any group which is appropriate and stable to the chemistry of the linker, in preferred aspects of the present dislcosure, the linker is independently covalently bonded to the ULM group and the PTM group preferably through an amide, ester, thioester, keto group, carbamate (urethane), carbon or ether, each of which groups may be inserted anywhere on the ULM group and PTM group to provide maximum binding of the ULM group on the ubiquitin ligase and the PTM group on the target protein to be degraded. (It is noted that in certain aspects where the PTM group is a ULM group, the target protein for degradation may be the ubiquitin ligase itself). In certain preferred aspects, the linker may be linked to an optionally substituted alkyl, alkylene, alkene or alkyne group, an aryl group or a heterocyclic group on the ULM and/or PTM groups.

recognizes a ubiquitin pathway protein (e.g., an ubiquitin ligase, such as an E3 ubiquitin ligase including cereblon, VHL, TAP, and/or MDM2) and the PTM recognizes the target protein such that degradation of the target protein will occur when the target protein is placed in proximity to the ubiquitin ligase, thus resulting in degradation/inhibition of the effects of the target protein and the control of protein levels. The control of protein levels afforded by the present disclosure provides treatment of a disease state or condition, which is modulated through the target protein by lowering the level of that protein in the cell, e.g., cell of a patient. In certain embodiments, the method comprises administering an effective amount of a compound as described herein, optionally including a pharamaceutically acceptable excipient, carrier, adjuvant, another bioactive agent or combination thereof.
[0353] In additional embodiments, the description provides methods for treating or ameliorating a disease, disorder or symptom thereof in a subject or a patient, e.g., an animal such as a human, comprising administering to a subject in need thereof a composition comprising an effective amount, e.g., a therapeutically effective amount, of a compound as described herein or salt form thereof, and a pharmaceutically acceptable excipient, carrier, adjuvant, another bioactive agent or combination thereof, wherein the composition is effective for treating or ameliorating the disease or disorder or symptom thereof in the subject.
[0354] In another aspect, the description provides methods for identifying the effects of the degradation of proteins of interest in a biological system using compounds according to the present disclosure.
[0355] In another embodiment, the present disclosure is directed to a method of treating a human patient in need for a disease state or condition modulated through a protein where the degradation of that protein will produce a therapeutic effect in the patient, the method comprising administering to a patient in need an effective amount of a compound according to the present disclosure, optionally in combination with another bioactive agent. The disease state or condition may be a disease caused by a microbial agent or other exogenous agent such as a virus, bacteria, fungus, protozoa or other microbe or may be a disease state, which is caused by overexpression and/or overactivation (e.g., a constitutively active) of a protein, which leads to a disease state and/or condition
[0356] The term "disease state or condition" is used to describe any disease state or condition wherein protein dysregulation (i.e., the amount of protein expressed in a patient is elevated) occurs and where degradation of one or more proteins in a patient may provide beneficial therapy or relief of symptoms to a patient in need thereof. In certain instances, the disease state or condition may be cured.
[0357] Disease states or conditions which may be treated using compounds according to the present disclosure include, for example, asthma, autoimmune diseases such as multiple sclerosis, various cancers, ciliopathies, cleft palate, diabetes, heart disease, hypertension, inflammatory bowel disease, mental retardation, mood disorder, obesity, refractive error, infertility, Angelman syndrome, Canavan disease, Coeliac disease, Charcot¨Marie¨Tooth disease, Cystic fibrosis, Duchenne muscular dystrophy, Haemochromatosis, Haemophilia, Klinefelter's syndrome, Neurofibromatosis, Phenylketonuria, Polycystic kidney disease, (PKD1) or 4 (PKD2) Prader¨
Willi syndrome, Sickle-cell disease, Tay¨Sachs disease, Turner syndrome.
Willi syndrome, Sickle-cell disease, Tay¨Sachs disease, Turner syndrome.
[0358] The term "neoplasia" or "cancer" is used throughout the specification to refer to the pathological process that results in the formation and growth of a cancerous or malignant neoplasm, i.e., abnormal tissue that grows by cellular proliferation, often more rapidly than normal and continues to grow after the stimuli that initiated the new growth cease. Malignant neoplasms show partial or complete lack of structural organization and functional coordination with the normal tissue and most invade surrounding tissues, metastasize to several sites, and are likely to recur after attempted removal and to cause the death of the patient unless adequately treated. As used herein, the term neoplasia is used to describe all cancerous disease states and embraces or encompasses the pathological process associated with malignant hematogenous, ascitic and solid tumors. Exemplary cancers which may be treated by the present compounds either alone or in combination with at least one additional anti-cancer agent include squamous-cell carcinoma, basal cell carcinoma, adenocarcinoma, hepatocellular carcinomas, and renal cell carcinomas, cancer of the bladder, bowel, breast, cervix, colon, esophagus, head, kidney, liver, lung, neck, ovary, pancreas, prostate, and stomach; leukemias; benign and malignant lymphomas, particularly Burkitt's lymphoma and Non-Hodgkin's lymphoma; benign and malignant melanomas; myeloproliferative diseases; sarcomas, including Ewing's sarcoma, hemangiosarcoma, Kaposi's sarcoma, liposarcoma, myosarcomas, peripheral neuroepithelioma, synovial sarcoma, gliomas, astrocytomas, oligodendrogliomas, ependymomas, gliobastomas, neuroblastomas, ganglioneuromas, gangliogliomas, medulloblastomas, pineal cell tumors, meningiomas, meningeal sarcomas, neurofibromas, and Schwannomas; bowel cancer, breast cancer, prostate cancer, cervical cancer, uterine cancer, lung cancer, ovarian cancer, testicular cancer, thyroid cancer, astrocytoma, esophageal cancer, pancreatic cancer, stomach cancer, liver cancer, colon cancer, melanoma; carcinosarcoma, Hodgkin's disease, Wilms' tumor and teratocarcinomas. Additional cancers which may be treated using compounds according to the present disclosure include, for example, T-lineage Acute lymphoblastic Leukemia (T-ALL), T-lineage lymphoblastic Lymphoma (T-LL), Peripheral T-cell lymphoma, Adult T-cell Leukemia, Pre-B ALL, Pre-B Lymphomas, Large B-cell Lymphoma, Burkitts Lymphoma, B-cell ALL, Philadelphia chromosome positive ALL and Philadelphia chromosome positive CML.
[0359] The term "bioactive agent" is used to describe an agent, other than a compound according to the present disclosure, which is used in combination with the present compounds as an agent with biological activity to assist in effecting an intended therapy, inhibition and/or prevention/prophylaxis for which the present compounds are used. Preferred bioactive agents for use herein include those agents which have pharmacological activity similar to that for which the present compounds are used or administered and include for example, anti-cancer agents, antiviral agents, especially including anti-HIV agents, anti-retrovirus and anti-HCV agents, antimicrobial agents, antifungal agents, etc.
[0360] The term "additional anti-cancer agent" is used to describe an anti-cancer agent, which may be combined with compounds according to the present disclosure to treat cancer.

General Synthetic Approach
General Synthetic Approach
[0365] The synthetic realization and optimization of the bifunctional molecules as described herein may be approached in a step-wise or modular fashion. For example, identification of compounds that bind to the target molecules can involve high or medium throughput screening campaigns if no suitable ligands are immediately available. It is not unusual for initial ligands to require iterative design and optimization cycles to improve suboptimal aspects as identified by data from suitable in vitro and pharmacological and/or ADMET assays. Part of the optimization/SAR campaign would be to probe positions of the ligand that are tolerant of substitution and that might be suitable places on which to attach the linker chemistry previously referred to herein. Where crystallographic or NMR structural data are available, these can be used to focus such a synthetic effort.
[0366] In a very analogous way one can identify and optimize ligands for an E3 Ligase, i.e.
ULMs/ILMs/VLMs/CLMs/ILMs.
ULMs/ILMs/VLMs/CLMs/ILMs.
[0367] With PTMs and ULMs (e.g. ILMs, VLMs, CLMs, and/or ILMs) in hand, one skilled in the art can use known synthetic methods for their combination with or without a linker moiety.
Linker moieties can be synthesized with a range of compositions, lengths and flexibility and functionalized such that the PTM and ULM groups can be attached sequentially to distal ends of the linker. Thus a library of bifunctional molecules can be realized and profiled in in vitro and in vivo pharmacological and ADMET/PK studies. As with the PTM and ULM groups, the final bifunctional molecules can be subject to iterative design and optimization cycles in order to identify molecules with desirable properties.

As with the PTM and ULM groups, the final bifunctional molecules can be subject to iterative design and optimization cycles in order to identify molecules with desirable properties.
[0368] In some instances, protecting group strategies and/or functional group interconversions (FGIs) may be required to facilitate the preparation of the desired materials.
Such chemical processes are well known to the synthetic organic chemist and many of these may be found in texts such as "Greene's Protective Groups in Organic Synthesis"

[0508] A compound of formula XLIX (readily prepared using standard reaction techniques known to one skilled in the art) may be reacted with a compound of formula.
[0509] A compound of formula XLIX may be reacted with a reagent XLIV under nucleophilic substitution conditions, e.g. diisopropylethylamine, potassium iodide, acetonitrile, 100 C, to produce a compound of formula L. L' represents an optional linker or portion of a linker; Nu-H represents a suitable nucleophile such as an alcohol or secondary amine; X
represents a suitable leaving group, e.g. p-toluenesulfonate, methanesulfonate, iodide, bromide, or chloride; L represents an optional linker; and PG represents a suitable ester protecting group, e.g. methyl, ethyl, or t-butyl. Compounds of formula L may be converted to a compound of formula LI by treatment with a reagent suitable for the removal of PG, e.g.
trifluoroacetic acid, dichloromethane, 30 C when PG is t-butyl. Compound LI may then be reacted with compounds XII as defined in Scheme 3A or 3B to produce compounds of formula LII under amide formation conditions, e.g. 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, 1-hydroxybenzotriazole, triethylamine, DMF, 30 C.

In some cases, X is a primary or secondary amine, optionally cyclized into a 4 to 8 membered heterocyclic ring, Y is a suitable leaving group such as fluorine or chlorine, and reaction conditions are those for a nucleophilic aromatic substitution, e.g.
triethylamine, DMSO, 70 C.
In these cases, Z becomes the corresponding secondary or tertiary amine derived from X.
In other cases, X is a suitable leaving group, e.g. p-toluenesulfonate, methanesulfonate, iodide, bromide, or chloride, Y is OH, and reaction conditions are those for a nucleophilic substitution, e.g. potassium carbonate, potassium iodide, DMSO, 60 C. In these cases, Z is 0.
In other cases, X is OH, Y is OH, and reaction conditions may be those for a Mitsunobu reaction, e.g. triphenylphosphine, diethylazodicarboxylate, THF. In these cases, Z is 0.
A compound of formula XXXVI may be further transformed into a different compound of formula XXXVI. When R' is a carboxylic ester and R" is CN, reduction of R" to CHO may be accomplished, e.g. by treatment with sodium hypophosphite and Raney nickel in a mixture of ,,,.....\
pyridine, acetic acid, and water. When R' and R" together form 0 , solvolysis e.g. with sodium hydroxide in an alcoholic solvent and tetrahydrofuran may afford a compound where R' is a carboxylic ester and R" is CH2OH. This compound may be further oxidized, e.g. with manganese dioxide, to afford an equivalent compound XXXVI where R' is a carboxylic ester and R" is CHO. Such compounds where R' is a carboxylic ester and R" is CHO may then be reacted with 3-aminoglutarimide in the presence of e.g. sodium triacetoxyborohydride, diisopropylethylamine, and acetic acid in methanol and dichloromethane to afford a new ,N1 0 compound of formula XXXVI wherein R' and R" together are -- Y , wherein Y
is CH2.
A compound of formula XXXVI may then be further transformed by reaction with a compound I
under palladium-catalyzed cross-coupling conditions, e.g. with a suitable palladium catalyst such as bis(di-tert-buty1(4-dimethylaminophenyl)phosphine)dichloropalladium(II), suitable base such as cesium fluoride, suitable solvent such as mixtures of 1,4-dioxane and water, at a suitable temperature such as 100 C, with or without microwave irradiation to produce a compound of formula XXXVII. Herein M', Z, and Z' are as defined in Scheme 1B.
In cases where one or both of Z or Z' are a protecting group, such protecting group may be removed from a compound XXXVII, e.g. by treatment with trifluoroacetic acid when Z and/or Z' are t-butoxycarbonyl, to afford a different compound of formula XXXVII wherein Z and Z' are H.
[0473] In cases where in R' and R" are both carboxylic esters in a compound XXXVII, hydrolysis e.g. with sodium hydroxide in methanol and water may afford a different compound XXXVII where R' and R" are CO2H. Such a compound may subsequently be reacted with e.g.
3-aminoglutarimide, (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate, and diisopropylamine in N,N-dimethylformamide to afford a new µ=1,-1( _tNH
