- P300 encoded by EP300
- CBP lysine acetyltransferases
- HATs lysine acetyltransferases
- the best defined substrates of P300 and CBP are histones. Acetylation of histones modulates the conformation of chromatin and generally leads to transcription activation.
- recruiting P300 and/or CBP is essential for many transcription factors and other transcription regulators to effectively promote regional transcription (Dancy and Cole, 2015).
- Substrates of P300 and CBP also include many non-histone proteins that have crucial physiological and pathological functions, such as p53, MYC, FOXOl, and NF-KB (Dancy and Cole, 2015). Because P300 and CBP functionally interact with a wide variety of signaling proteins, these two lysine
- acetyltransferases act as the converge point of many signal transduction pathways (Bedford et al., 2010). Through modulating acetylation of diverse substrates and connecting a multitude of binding partners,
- P300 and CBP are widely implicated in biological processes, such as cellular proliferation, differentiation, development, DNA repair, inflammation, metabolism, and memory.
- P300 and CBP are indispensable for development, as mice deficient in either P300 or CBP die early during embryogenesis (Goodman and Smolik, 2000). Aberrant P300 or CBP are associated with a wide range of human diseases. Germline mutations that inactivate one of CREBBP alleles result in the Rubinstein-Taybi syndrome (Petrij et al., 1995), probably due to impaired activation of the Hedgehog family transcription factors. Both P300 and CBP are known to contribute to hematopoiesis, through interaction with hematopoietic transcription factors, such as GATA-1 (Blobel, 2000). Tumor suppressive roles of P300 and CBP have been well defined.
- P300 has been reported to regulate immune cell functions (Liu et al., 2013). Further, P300 and CBP are important transcription co-activators for the STAT and NF- KB family transcription factors (Nadiminty et al., 2006; Wang et al., 2005; Wang et al., 2017), which have crucial functions in immune cells. Therefore, P300/CBP antagonizers may be employed to modulate activities of the immune system and the crosstalk between immune cells and cancer cells (Liu et al., 2013). Finally, it has been extensively documented that histone acetylation is crucially implicated in
- P300 and CBP share nearly 75% similarity and 63% identity in protein sequences. Greater homology is found in functional domains that are highly conserved during evolution. Most of these domains mediate protein-protein interactions, such as the Cysteine-Histidine-rich region 1 (CHI), the CREB-interacting KIX domain, the Cysteine-Histidine-rich region (CH3), and the nuclear receptor co-activator binding domain (Wang et al., 2013a). However, these domains are less amenable to small molecule-mediated intervention. Only few inhibitors have been reported.

- YH249 and YH250 (Yusuke et al., 2016) were reported to selectivily inhibit P300-dependent transcription.
- Recent efforts to develop small molecule probes for P300 and CBP are concentrated on the HAT domain and the bromodomain.
- the HAT domain is responsible to catalyze transfer of acetyl groups, while the bromodomain binds to acetylated lysine residues, which promotes interaction of P300 and CBP to acetylated chromatin.

- HAT or bromodomain inhibitors have exhibited anti-cancer activities in a wide range of human cancers, including but are not limited to prostate cancer (Jin et al., 2017; Lasko et al., 2017), breast cancer (Y ang et al., 2013), lung cancer (Ogiwara et al., 2016; Oike et al., 2014), acute myeloid leukemia (Giotopoulos et al., 2016), and melanoma (Wang et al.,
- P300 and CBP have multiple functional domains. Blockade of either the HAT domains or the bromodomains only lead to partial inhibition of their activities. The scaffolding functions P300 and CBP are not effectively modulated by these small molecule inhibitors. Second, the HAT domains and the bromodomains of P300 and CBP share significant homology so that most small molecule compounds do not effectively differentiate these two targets. Conversely, P300 and CBP have distinct tissue type-dependent roles. For example, in prostate cancer, P300 is the dominating co-activator of androgen receptor, while CBP has limited roles (Ianculescu et al., 2012).
- the present disclosure is believed to be based, at least in part, on the discovery that novel heterobifimctional small molecules which degrade CBP/P300, CBP/P300 fusion proteins, and/or CBP/P300 mutant proteins (“PROteolysis TArgeting Chimeras”/“PROTACs” and “Specific and Nongenetic IAP-dependent Protein Erasers”/“SNIPERs”) are useful in the treatment of CBP/P300-mediated diseases, particularly prostate cancer (Jin et al., 2017; Lasko et al., 2017), breast cancer (Y ang et al., 2013), lung cancer (Ogiwara et al., 2016; Oike et al., 2014), acute myeloid leukemia (Giotopoulos et al., 2016), and melanoma (Wang et al., 2018).

- PROTACs are bivalent inhibitors having one moiety that binds to an E3 ubiquitin ligase and another moiety that binds the protein target of interest (Buckley and Crews, 2014).

- a hydrophobic tagging approach which utilizes a bulky and hydrophobic adamantyl group, has been developed to mimic protein misfolding, leading to the degradation of the target protein by proteasome (Buckley and Crews, 2014).
- This approach has been applied to selective degradation of the pseudokinase HER3 (Xie et al., 2014).

- a novel approach is taken: to develop compounds that directly and selectively modulate not only the protein-protein interactions and acetyltransferase activity of CBP/P300, but also their protein levels.
- Strategies for inducing protein degradation include recruiting E3 ubiquitin ligases, mimicking protein misfolding with hydrophobic tags, and inhibiting chaperones.

- a fluorinated variation is a compound in which at least one hydrogen atom is replaced by a fluoro atom. Fluorinated variations can provide therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements.
- prodrugs of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (e.g., converting hydroxyl groups or carboxylic acid groups to ester groups).
- a prodrug refers to a compound that can be converted via some chemical or physiological process (e.g., enzymatic processes and metabolic hydrolysis) to a therapeutic agent.
- prodrug also refers to a precursor of a biologically active compound that is pharmaceutically acceptable.
- a prodrug may be inactive when administered to a subject, i.e. an ester, but is converted in vivo to an active compound, for example, by hydrolysis to the free carboxylic acid or free hydroxyl.
- the prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in an organism.
- prodrug is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a subject.
- Prodrugs of an active compound may be prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound.
- Prodrugs include compounds wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively.
- Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of an alcohol or acetamide, formamide and benzamide derivatives of an amine functional group in the active compound and the like.
- LNCaP or 22RV1 cells Specific exemplary bivalent compounds were characterized in LNCaP or 22RV1 cells.
- LNCaP or 22RV1 cells that express CBP/P300 proteins were treated with GNE-781 or the bivalent compounds disclosed herein (P-001 to P-174) for indicated hours. Cells were collected, lysed and subject to immunoblotting using an antibody specific to P300 or CBP proteins. Tubulin or vinculin was included as the loading control. DMSO was used as the negative control.
- P300 and CBP protein levels in LNCaP or 22RV1 cells were significantly decreased ( Figure 1, 2, 5, 6, 10, and 11).
- Selected bivalent compounds disclosed herein were found to be particularly effective in reducing CBP and P300 protein levels, as the concentrations required to reduce target protein levels by 50% (DC 50 ) for some compounds were less than 1 nM ( Figure 6).
- LNCaP cells were treated with 20 nM P-004, P-005, P-015, or P-020 for the indicated time. Subsequently, changes in P300 protein levels were measured via immunoblotting. Tubulin was included as the loading control. Significant degradation of P300 was readily detected as early as 2 hours following administration of the compounds ( Figure 3).
- the interaction with cereblon is critical to the ability of bivalent compounds to induce degradation of P300/CBP proteins, as a chemical modification that disrupted cereblon binding abolished P300 degradation induced by P-034 in LNCap and 22RV1 cells (Figure 7).
- the degradation was also dependent on the ubiquitin-proteasome system, because it could be neutralized by co-administration of proteasome inhibitors, MG- 132 and bortezomib, a cullin E3 ligase inhibitor, MLN4924, or high concentration of pomalidomide that compete for cereblon binding, as exemplified by P-007, P-034, and P-100 (Figure 8).
- bivalent compounds induce degradation of P300/CBP proteins via a mechanism specifically mediated by cereblon, cullin E3 ligases, and the proteasome.
- athymic nude mice bearing 22RV 1 subcutaneous xenograft tumors at the right flank were intrapreitoneally or orally treated with 40 mg/kg bivalent compounds.
- animals were sacrificed for immunoblotting of P300 and CBP in homogenized xenograft tumor masses.

DETAILED DESCRIPTION OF THE INVENTION
Posttranslational modifications of proteins, such as phosphorylation, acetylation, methylation, and ubiquitination, greatly contribute to the diversity and regulation of proteins. P300 (encoded by EP300) and the closely related CBP (encode by CREBBP) are two extensively studied lysine acetyltransferases (HATs) that catalyze transfer of acetyl groups to lysine residues of proteins. The best defined substrates of P300 and CBP are histones. Acetylation of histones modulates the conformation of chromatin and generally leads to transcription activation. Recruiting P300 and/or CBP is essential for many transcription factors and other transcription regulators to effectively promote regional transcription (Dancy and Cole, 2015). Substrates of P300 and CBP also include many non-histone proteins that have crucial physiological and pathological functions, such as p53, MYC, FOXOl, and NF-KB (Dancy and Cole, 2015). Because P300 and CBP functionally interact with a wide variety of signaling proteins, these two lysine
acetyltransferases act as the converge point of many signal transduction pathways (Bedford et al., 2010). Through modulating acetylation of diverse substrates and connecting a multitude of binding partners,
P300 and CBP are widely implicated in biological processes, such as cellular proliferation, differentiation, development, DNA repair, inflammation, metabolism, and memory.
Both P300 and CBP are indispensable for development, as mice deficient in either P300 or CBP die early during embryogenesis (Goodman and Smolik, 2000). Aberrant P300 or CBP are associated with a wide range of human diseases. Germline mutations that inactivate one of CREBBP alleles result in the Rubinstein-Taybi syndrome (Petrij et al., 1995), probably due to impaired activation of the Hedgehog family transcription factors. Both P300 and CBP are known to contribute to hematopoiesis, through interaction with hematopoietic transcription factors, such as GATA-1 (Blobel, 2000). Tumor suppressive roles of P300 and CBP have been well defined. Patients with Rubinstein-Taybi syndrome have higher cancer prevalence. Inactivating mutations of P300 and CBP are frequently found in human cancers (Giles et al., 1998). However, these two HATs also promote oncogenesis via different mechanisms. In a subset of acute myeloid leukemia, recurrent chromosomal translocations t(8;16)(pl 1 ;p 13) produce in-frame fusions of the MOZ gene and the CREBBP gene that direct expression of oncogenic MOZ-CBP fusion proteins (Rozman et al., 2004). CBP, and less frequently P300, are also found to fuse with MLL in chemoresistant leukemia (Sobulo et al., 1997). Accumulating evidence show that P300 and CBP are recruited as co-activators by the majority of oncogenic transcription factors, such as MYC (Faiola et al., 2005; Vervoorts et al., 2003), NF-KB (Vanden Berghe et al., 1999), b-catenin (Sun et al., 2000), E2F1 (Ianari et al., 2004; Martinez-Balbas et al., 2000), and nuclear receptors (Chakravarti et al., 1996). Hence, depleting P300 and/or CBP may compromise tumor growth through impairing the functions of these oncogenic transcription factors. Additionally, P300 has been reported to regulate immune cell functions (Liu et al., 2013). Further, P300 and CBP are important transcription co-activators for the STAT and NF- KB family transcription factors (Nadiminty et al., 2006; Wang et al., 2005; Wang et al., 2017), which have crucial functions in immune cells. Therefore, P300/CBP antagonizers may be employed to modulate activities of the immune system and the crosstalk between immune cells and cancer cells (Liu et al., 2013). Finally, it has been extensively documented that histone acetylation is crucially implicated in
neurodegenerative diseases (Saha and Pahan, 2006; Valor et al., 2013). Taken together, developing novel therapeutic agents targeting P300 and CBP represents novel opportunities for the treatment of cancer, inflammatory diseases, neurological indications, and other indications.
P300 and CBP share nearly 75% similarity and 63% identity in protein sequences. Greater homology is found in functional domains that are highly conserved during evolution. Most of these domains mediate protein-protein interactions, such as the Cysteine-Histidine-rich region 1 (CHI), the CREB-interacting KIX domain, the Cysteine-Histidine-rich region (CH3), and the nuclear receptor co-activator binding
domain (Wang et al., 2013a). However, these domains are less amenable to small molecule-mediated intervention. Only few inhibitors have been reported. For example, naphthol-AS-E (Uttarkar et al., 2015), compound 1-10 (Wang et al., 2013b), and MYBMIM (Ramaswamy et al., 2018) are reported as KIX domain inhibitors. KCN1 (Shi et al., 2012; Yin et al., 2012), OHM1 (Lao et al., 2014), HBS1 (Kushal et al., 2013), and KCN1 analogs (Ferguson et al., 2017) were discovered as disruptors of TAZl/HIF-la protein protein interactions. ICG-001 (Emami et al., 2004) was reported as selective inhibitor of CBP NRID/b -eaten in interactions. In addition, YH249 and YH250 (Yusuke et al., 2016) were reported to selectivily inhibit P300-dependent transcription. Recent efforts to develop small molecule probes for P300 and CBP are concentrated on the HAT domain and the bromodomain. The HAT domain is responsible to catalyze transfer of acetyl groups, while the bromodomain binds to acetylated lysine residues, which promotes interaction of P300 and CBP to acetylated chromatin. A variety of small molecule compounds, including GNE-781(Bronner et al., 2017), GNE-272 (Bronner et al., 2017), GNE-207 (Lai et al., 2018), CPD 4d (Hewings et al., 2011), CPD (S)-8 (Hewings et al., 2013), CPD (R)-2 (Rooney et al., 2014),
CPD6 (Unzue et al., 2016), CPD 19 (Unzue et al., 2016), XDM-CBP (Hugle et al., 2017; Unzue et al.,
2016), I-CBP112 (Picaud et al., 2015), TPOP146 (Popp et al., 2016), CPI-637 (Taylor et al., 2016), SGC- CBP30 (Hammitzsch et al., 2015; Hay et al., 2014), CPD 11 (Denny et al., 2017), CPD 41 (Denny et al.,
2017), CPD 30 (Lai et al., 2018), CPD 5 (Bronner et al., 2017), CPD 27 (Bronner et al., 2017), CPD 29 (Bronner et al., 2017), and CCS1477 (clinical trial ID: NCT03568656), have been described to target the bromodomain of P300 and CBP HAT domain targeting P300/CBP inhibitors, C646 (Oike et al., 2014) and A-485 (Lasko et al., 2017), were reported. Transcription dependent on P300 or CBP is partially compromised by these compounds (Wei et al., 2018). These HAT or bromodomain inhibitors have exhibited anti-cancer activities in a wide range of human cancers, including but are not limited to prostate cancer (Jin et al., 2017; Lasko et al., 2017), breast cancer (Y ang et al., 2013), lung cancer (Ogiwara et al., 2016; Oike et al., 2014), acute myeloid leukemia (Giotopoulos et al., 2016), and melanoma (Wang et al.,
2018). However, there are significant caveats using these small molecule inhibitors to modulate the activities of P300 and CBP. First, P300 and CBP have multiple functional domains. Blockade of either the HAT domains or the bromodomains only lead to partial inhibition of their activities. The scaffolding functions P300 and CBP are not effectively modulated by these small molecule inhibitors. Second, the HAT domains and the bromodomains of P300 and CBP share significant homology so that most small molecule compounds do not effectively differentiate these two targets. Conversely, P300 and CBP have distinct tissue type-dependent roles. For example, in prostate cancer, P300 is the dominating co-activator of androgen receptor, while CBP has limited roles (Ianculescu et al., 2012). Thus, simultaneously targeting both P300 and CBP is not always necessary and may result in more significant adverse effects than selectively targeting one of them. Not to mention many P300/CBP inhibitors have off-target effects that have been poorly defined. To improve the selectivity and activity of anti-P300/CBP therapy, approaches that selectively degrade the target protein(s) are expected to have substantial advantages.
Without wishing to be bound by any theory, the present disclosure is believed to be based, at least in part, on the discovery that novel heterobifimctional small molecules which degrade CBP/P300, CBP/P300 fusion proteins, and/or CBP/P300 mutant proteins (“PROteolysis TArgeting Chimeras”/“PROTACs” and “Specific and Nongenetic IAP-dependent Protein Erasers”/“SNIPERs”) are useful in the treatment of CBP/P300-mediated diseases, particularly prostate cancer (Jin et al., 2017; Lasko et al., 2017), breast cancer (Y ang et al., 2013), lung cancer (Ogiwara et al., 2016; Oike et al., 2014), acute myeloid leukemia (Giotopoulos et al., 2016), and melanoma (Wang et al., 2018).
Selective degradation of a target protein induced by a small molecule may be achieved by recruiting an E3 ubiquitin ligase and mimicking protein misfolding with a hydrophobic tag (Buckley and Crews,
2014). Additionally, PROTACs are bivalent inhibitors having one moiety that binds to an E3 ubiquitin ligase and another moiety that binds the protein target of interest (Buckley and Crews, 2014). The induced proximity leads to ubiquitination of the target followed by its degradation via proteasome-mediated proteolysis. Several types of high affinity small-molecule E3 ligase ligands have been identified or developed. They include (1) immunomodulatory drugs (IMiDs) such as thalidomide and pomalidomide, which bind cereblon (CRBN or CRL4CRBN), a component of a cullin-RING ubiquitin ligase (CRL) complex (Bondeson et al., 2015; Chamberlain et al., 2014; Fischer et al., 2014; Ito et al., 2010; Winter et al., 2015); (2) VHL-1, a hydroxyproline-containing ligand, which binds van Hippel-Lindau protein (VHL or CRL2VHL), a component of another CRL complex (Bondeson et al., 2015; Buckley et al., 2012a; Buckley et al., 2012b; Galdeano et al., 2014; Zengerle et al., 2015); (3) compound 7, which selectively binds KEAP1, a component of a CRL3 complex(Davies et al., 2016); (4) AMG232, which selectively binds MDM2, a heterodimeric RING E3 ligase(Sun et al., 2014); and (5) LCL161, which selectively binds IAP, a homodimeric RING E3 ligase (Ohoka et al., 2017; Okuhira et al., 2011; Shibata et al., 2017). The PROTAC technology has been applied to degradation of several protein targets (Bondeson et al., 2015; Buckley et al., 2015; Lai et al., 2016; Lu et al., 2015; Winter et al., 2015; Zengerle et al., 2015). In addition, a hydrophobic tagging approach, which utilizes a bulky and hydrophobic adamantyl group, has been developed to mimic protein misfolding, leading to the degradation of the target protein by proteasome (Buckley and Crews, 2014). This approach has been applied to selective degradation of the pseudokinase HER3 (Xie et al., 2014). The inventors have not yet seen any efforts applying any of these approaches to degradation of CBP/P300, CBP/P300 mutant, CBP/P300 deletion, or CBP/P300 fusion proteins.
Currently available small molecules targeting CBP/P300 focus on inhibition of the protein interactions or acetryltransferase activities of CBP/P300. A number of selective small-molecule
CBP/P300 inhibitors, such as GNE-781, GNE-272, GNE-207, CPD 4d, CPD (S)-8, CPD (R)-2, CPD6, CPD19, XDM-CBP, I-CBP112, TPOP146, CPI-637, SGC-CBP30, CPD 11, CPD 41, CPD 30, CPD 5, CPD 27, CPD 29, CCS 1477 (clinical trial ID: NCT03568656), C646 (Oike et al., 2014), A-485, naphthol-AS-E (Uttarkar et al., 2015), compound 1-10 (Wang et al., 2013b), MYBMIM (Ramaswamy et al., 2018), KCN1 (Shi et al., 2012; Yin et al., 2012), OHM1 (Lao et al., 2014), HBS1 (Kushal et al., 2013), and KCN1 analogs (Ferguson et al., 2017), ICG-001 (Emami et al., 2004), YH249 (Yusuke et al., 2016) and YH250 (Y usuke et al., 2016) have been reported.
In the present disclosure, a novel approach is taken: to develop compounds that directly and selectively modulate not only the protein-protein interactions and acetyltransferase activity of CBP/P300, but also their protein levels. Strategies for inducing protein degradation include recruiting E3 ubiquitin ligases, mimicking protein misfolding with hydrophobic tags, and inhibiting chaperones. Such an approach, based on the use of bivalent small molecule compounds, permits more flexible regulation of protein levels in vitro and in vivo compared with techniques such as gene knockout or short hairpin RNA- mediated (shRNA) knockdown. Unlike gene knockout or shRNA knockdown, a small molecule approach further provides an opportunity to study dose and time dependency in a disease model through modulating the administration routes, concentrations and frequencies of administration of the corresponding small molecule.

Linker Moiety
As used herein, a“linker” or“linker moiety” is a bond, molecule, or group of molecules that binds two separate entities to one another. Linkers provide for optimal spacing of the two entities. The term “linker” in some aspects refers to any agent or molecule that bridges the CBP/P300 ligand to the degradation tag. One of ordinary skill in the art recognizes that sites on the CBP/P300 ligand or the degradation tag, which are not necessary for the function of the PROTACs or SNIPERs of the present disclosure, are ideal sites for attaching a linker, provided that the linker, once attached to the conjugate of the present disclosures, does not interfere with the function of the CBP/P300 ligand, i.e., its ability to bind CBP/P300, or the function of the degradation tag, i.e., its ability to recruit a ubiquitin ligase.
The length of the linker of the bivalent compound can be adjusted to minimize the molecular weight of the bivalent compounds, avoid the clash of the CBP/P300 ligand or targeting moiety with the ubiquitin ligase and/or induce CBP/P300 misfolding by the hydrophobic tag. In certain embodiments, the linker comprises acyclic or cyclic saturated or unsaturated carbon, ethylene glycol, amide, amino, ether, urea, carbamate, aromatic, heteroaromatic, heterocyclic or carbonyl groups. In certain embodiments, the length of the linker is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more atoms.

Without wishing to be bound by any particular theory, it is contemplated herein that, in some embodiments, attaching pomalidomide or VHL-1 to either portion of the molecule can recruit the cereblon E3 ligase or VHL E3 ligase to CBP/P300.
The bivalent compounds disclosed herein can selectively affect CBP/P300-mediated disease cells compared to WT (wild type) cells (i.e., an bivalent compound able to kill or inhibit the growth of an CBP/P300-mediated disease cell while also having a relatively low ability to lyse or inhibit the growth of a WT cell), e.g., possess a GI50 for one or more CBP/P300-mediated disease cells more than 1.5-fold lower, more than 2-fold lower, more than 2.5-fold lower, more than 3-fold lower, more than 4-fold lower, more than 5-fold lower, more than 6-fold lower, more than 7-fold lower, more than 8-fold lower, more than 9-fold lower, more than 10-fold lower, more than 15 -fold lower, or more than 20-fold lower than its GI50 for one or more WT cells, e.g., WT cells of the same species and tissue type as the CBP/P300- mediated disease cells.

In certain embodiments, the cell is a cancer cell. In certain embodiments, the cancer cell is a CBP/P300-mediated cancer cell.
Synthesis and Testing of Bivalent Compounds
The binding affinity of novel synthesized bivalent compounds can be assessed using standard biophysical assays known in the art (e.g., isothermal titration calorimetry (ITC), surface plasmon resonance (SPR)). Cellular assays can then be used to assess the bivalent compound’s ability to induce CBP/P300 degradation and inhibit cancer cell proliferation. Besides evaluating a bivalent compound’s induced changes in the protein levels of CBP/P300, CBP/P300 mutants, or CBP/P300 fusion proteins, protein-protein interaction or acteryltransferase enzymatic activity can also be assessed. Assays suitable for use in any or all of these steps are known in the art, and include, e.g., western blotting, quantitative mass spectrometry (MS) analysis, flow cytometry, enzymatic activity assay, ITC, SPR, cell growth inhibition, xenograft, orthotopic, and patient-derived xenograft models. Suitable cell lines for use in any or all of these steps are known in the art and include LNCaP, 22RV1, HEL, MV4;11, RS4;11, NCI-H929, MM. IS, Pfeiffer, NCI-H520 and other cell lines. Suitable mouse models for use in any or all of these steps are known in the art and include subcutaneous xenograft models, orthotopic models, patient-derived xenograft models, and patient-derived orthotopic models.
By way of non-limiting example, detailed synthesis protocols are described in the Examples for specific exemplary bivalent compounds.
Pharmaceutically acceptable isotopic variations of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (substituting appropriate reagents with appropriate isotopic variations of those reagents). Specifically, an isotopic variation is a compound in which at least one atom is replaced by an atom having the same atomic number, but an atomic mass different from the atomic mass usually found in nature. Useful isotopes are known in the art and include, for example, isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine. Exemplary isotopes thus include, e.g., 2H, 3H, 13C, 14C, 15N, 170, 180, 32P, 35S, 18F, and 36C1.
Isotopic variations (e.g., isotopic variations containing 2H) can provide therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements. In addition, certain isotopic variations (particularly those containing a radioactive isotope) can be used in drug or substrate tissue distribution studies. The radioactive isotopes tritium (3H) and carbon-14 (14C) are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.
Pharmaceutically acceptable solvates of the compounds disclosed herein are contemplated. A solvate can be generated, e.g., by substituting a solvent used to crystallize a compound disclosed herein with an isotopic variation (e.g., D 0 in place of H20, ¾-acetone in place of acetone, or ri6-DMSO in place of DMSO).
Pharmaceutically acceptable fluorinated variations of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (substituting appropriate reagents with appropriate fluorinated variations of those reagents). Specifically, a fluorinated variation is a compound in which at least one hydrogen atom is replaced by a fluoro atom. Fluorinated variations can provide therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements.
Pharmaceutically acceptable prodrugs of the compounds disclosed herein are contemplated and can be synthesized using conventional methods known in the art or methods corresponding to those described in the Examples (e.g., converting hydroxyl groups or carboxylic acid groups to ester groups). As used herein, a "prodrug" refers to a compound that can be converted via some chemical or physiological process (e.g., enzymatic processes and metabolic hydrolysis) to a therapeutic agent. Thus, the term "prodrug" also refers to a precursor of a biologically active compound that is pharmaceutically acceptable. A prodrug may be inactive when administered to a subject, i.e. an ester, but is converted in vivo to an active compound, for example, by hydrolysis to the free carboxylic acid or free hydroxyl. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in an organism.
The term "prodrug" is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a subject. Prodrugs of an active compound may be prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound.
Prodrugs include compounds wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of an alcohol or acetamide, formamide and benzamide derivatives of an amine functional group in the active compound and the like.
Characterization of Exemplary Bivalent Compounds
Specific exemplary bivalent compounds were characterized in LNCaP or 22RV1 cells. LNCaP or 22RV1 cells that express CBP/P300 proteins were treated with GNE-781 or the bivalent compounds disclosed herein (P-001 to P-174) for indicated hours. Cells were collected, lysed and subject to immunoblotting using an antibody specific to P300 or CBP proteins. Tubulin or vinculin was included as the loading control. DMSO was used as the negative control. Following treatment of various bivalent compounds, P300 and CBP protein levels in LNCaP or 22RV1 cells were significantly decreased (Figure 1, 2, 5, 6, 10, and 11). Selected bivalent compounds disclosed herein were found to be particularly effective in reducing CBP and P300 protein levels, as the concentrations required to reduce target protein levels by 50% (DC50) for some compounds were less than 1 nM (Figure 6).
In addition, LNCaP cells were treated with 20 nM P-004, P-005, P-015, or P-020 for the indicated time. Subsequently, changes in P300 protein levels were measured via immunoblotting. Tubulin was included as the loading control. Significant degradation of P300 was readily detected as early as 2 hours following administration of the compounds (Figure 3).
It has been demonstrated that targeting CBP/P300 using ligands to their bromodomains or lysine acetyltransferase domains compromises cancer cell proliferation and survival (Jin et al., 2017; Lasko et al., 2017; Picaud et al., 2015; Popp et al., 2016). LNCaP cells seeded in 96-well plates were treated with 10 mM GNE-781 or selected bivalent compounds, i.e. P-001, P-002, and P-019, following a 12-point 3 -fold serial dilution. Three days after treatment, cell viability was determined using the CellTiter-Glo kit (Promega) following manufacturer’s instructions. Cell viability was normalized to the mean values of 3 replicates of untreated cells. Dose-dependent response was analyzed following the least-squares non linear regression method using the GraphPad Prism 5.0 software. Bivalent compounds dose-dependently suppressed viability of LNCaP cells, as exemplified by P-001, P-002, and P-019 (Figure 4, Table 2-3). These results collectively demonstrated that downregulation of CBP/P300 proteins levels using bivalent compounds described herein induced antineoplastic activities.
The interaction with cereblon is critical to the ability of bivalent compounds to induce degradation of P300/CBP proteins, as a chemical modification that disrupted cereblon binding abolished P300 degradation induced by P-034 in LNCap and 22RV1 cells (Figure 7). The degradation was also dependent on the ubiquitin-proteasome system, because it could be neutralized by co-administration of proteasome inhibitors, MG- 132 and bortezomib, a cullin E3 ligase inhibitor, MLN4924, or high concentration of pomalidomide that compete for cereblon binding, as exemplified by P-007, P-034, and P-100 (Figure 8).
These findings collectively demonstrate that bivalent compounds induce degradation of P300/CBP proteins via a mechanism specifically mediated by cereblon, cullin E3 ligases, and the proteasome. In addition to cultured cells, athymic nude mice bearing 22RV 1 subcutaneous xenograft tumors at the right flank were intrapreitoneally or orally treated with 40 mg/kg bivalent compounds. Six hours after drug administration, animals were sacrificed for immunoblotting of P300 and CBP in homogenized xenograft tumor masses. Bivalent compounds, as exemplified by P-100, P-007 and P-034, exhibited the ability of significantly reducing P300 and CBP protein levels after a single dose of drug administration (Figure 9). Moreoever, ICR mice were orally treated with 40 mg/kg bivalent compounds. Six hours after drug administration, animals were sacrificed for immunoblotting of CBP in homogenized lung tissues. Bivalent compounds, as exemplified in Figure 12, exhibited the ability of significantly reducing CBP protein levels after a single dose of drug administration.

In some aspects, subject selection can include obtaining a sample from a subject (e.g., a candidate subject) and testing the sample for an indication that the subject is suitable for selection. In some aspects, the subject can be confirmed or identified, e.g. by a health care professional, as having had, having an elevated risk to have, or having a condition or disease. In some aspects, suitable subjects include, for example, subjects who have or had a condition or disease but that resolved the disease or an aspect thereof, present reduced symptoms of disease (e.g., relative to other subjects (e.g., the majority of subjects) with the same condition or disease), or that survive for extended periods of time with the condition or disease (e.g., relative to other subjects (e.g., the majority of subjects) with the same condition or disease), e.g., in an asymptomatic state (e.g., relative to other subjects (e.g., the majority of subjects) with the same condition or disease). In some aspects, exhibition of a positive immune response towards a condition or disease can be made from patient records, family history, or detecting an indication of a positive immune response. In some aspects, multiple parties can be included in subject selection. For example, a first party can obtain a sample from a candidate subject and a second party can test the sample. In some aspects, subjects can be selected or referred by a medical practitioner (e.g., a general practitioner). In some aspects, subject selection can include obtaining a sample from a selected subject and storing the sample or using the in the methods disclosed herein. Samples can include, e.g., cells or populations of cells.
In some aspects, methods of treatment can include a single administration, multiple administrations, and repeating administration of one or more compounds disclosed herein as required for the prevention or treatment of the disease or condition disclosed herein (e.g., an CBP/P300-mediated disease). In some aspects, methods of treatment can include assessing a level of disease in the subject prior to treatment, during treatment, or after treatment. In some aspects, treatment can continue until a decrease in the level of disease in the subject is detected.
The term“subject,” as used herein, refers to any animal. In some instances, the subject is a mammal. In some instances, the term“subject,” as used herein, refers to a human (e.g., a man, a woman, or a child).
The terms“administer,”“administering,” or“administration,” as used herein, refer to implanting, ingesting, injecting, inhaling, or otherwise absorbing a compound or composition, regardless of form. For example, the methods disclosed herein include administration of an effective amount of a compound or composition to achieve the desired or stated effect.
The terms“treat”,“treating,” or“treatment,” as used herein, refer to partially or completely alleviating, inhibiting, ameliorating, or relieving the disease or condition from which the subject is suffering. This means any manner in which one or more of the symptoms of a disease or disorder (e.g., cancer) are ameliorated or otherwise beneficially altered. As used herein, amelioration of the symptoms of a particular disorder (e.g., cancer) refers to any lessening, whether permanent or temporary, lasting or transient that can be attributed to or associated with treatment by the bivalent compounds, compositions and methods of the present invention. In some embodiments, treatment can promote or result in, for example, a decrease in the number of tumor cells (e.g., in a subject) relative to the number of tumor cells prior to treatment; a decrease in the viability (e.g., the average/mean viability) of tumor cells (e.g., in a subject) relative to the viability of tumor cells prior to treatment; a decrease in the rate of growth of tumor
cells; a decrease in the rate of local or distant tumor metastasis; or reductions in one or more symptoms associated with one or more tumors in a subject relative to the subject’s symptoms prior to treatment.
The terms“prevent,”“preventing,” and“prevention,” as used herein, shall refer to a decrease in the occurrence of a disease or decrease in the risk of acquiring a disease or its associated symptoms in a subject. The prevention may be complete, e.g., the total absence of disease or pathological cells in a subject. The prevention may also be partial, such that the occurrence of the disease or pathological cells in a subject is less than, occurs later than, or develops more slowly than that which would have occurred without the present invention. In certain embodiments, the subject has an elevated risk of developing one or more CBP/P300-mediated diseases. Exemplary CBP/P300-mediated diseases that can be treated with bivalent compounds include, for example, acoustic neuroma, acute leukemia, acute lymphocytic leukemia, acute myelocytic leukemia, acute T-cell leukemia, basal cell carcinoma, bile duct carcinoma, bladder cancer, brain choriocarcinoma, chronic leukemia, chronic lymphocytic leukemia, chronic myelocytic leukemia, chronic myelogenous leukemia, colon cancer, colorectal cancer, craniopharyngioma, cystadenocarcinoma, diffuse large B-cell lymphoma, dysproliferative changes, embryonal carcinoma, endometrial cancer, endotheliosarcoma, ependymoma, epithelial carcinoma, erythroleukemia, esophageal cancer, estrogen-receptor positive breast cancer, essential thrombocythemia, Ewing's tumor, fibrosarcoma, follicular lymphoma, germ cell testicular cancer, glioma, glioblastoma, gliosarcoma, heavy chain disease, head and neck cancer, hemangioblastoma, hepatoma, hepatocellular cancer, hormone insensitive prostate cancer, leiomyosarcoma, leukemia, liposarcoma, lung cancer, lymphagioendotheliosarcoma, lymphangiosarcoma, lymphoblastic leukemia, lymphoma, lymphoid malignancies of T- cell or B-cell origin, medullary carcinoma, medulloblastoma, melanoma, meningioma, mesothelioma, multiple myeloma, myelogenous leukemia, myeloma, myxosarcoma, neuroblastoma, NUT midline carcinoma (NMC), non-small cell lung cancer, oligodendroglioma, oral cancer, osteogenic sarcoma, ovarian cancer, pancreatic cancer, papillary adenocarcinomas, papillary carcinoma, pinealoma, polycythemia vera, prostate cancer, rectal cancer, renal cell carcinoma, retinoblastoma, rhabdomyosarcoma, sarcoma, sebaceous gland carcinoma, seminoma, skin cancer, small cell lung carcinoma, solid tumors (carcinomas and sarcomas), small cell lung cancer, stomach cancer, squamous cell carcinoma, synovioma, sweat gland carcinoma, thyroid cancer, Waldenstrom's macroglobulinemia, testicular tumors, uterine cancer, Wilms' tumor, Addison's disease, acute gout, ankylosing spondylitis, asthma, atherosclerosis, Behcet's disease, bullous skin diseases, chronic obstructive pulmonary disease, Crohn's disease, dermatitis, eczema, giant cell arteritis, fibrosis, glomerulonephritis, hepatic vascular occlusion, hepatitis, hypophysitis,

Specific dosage and treatment regimens for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient’s disposition to the disease, condition or symptoms, and the judgment of the treating physician.
An effective amount can be administered in one or more administrations, applications or dosages. A therapeutically effective amount of a therapeutic compound (i.e., an effective dosage) depends on the therapeutic compounds selected. Moreover, treatment of a subject with a therapeutically effective amount
of the compounds or compositions described herein can include a single treatment or a series of treatments. For example, effective amounts can be administered at least once. The compositions can be administered from one or more times per day to one or more times per week; including once every other day. The skilled artisan will appreciate that certain factors can influence the dosage and timing required to effectively treat a subject, including but not limited to the severity of the disease or disorder, previous treatments, the general health or age of the subject, and other diseases present.
Following administration, the subject can be evaluated to detect, assess, or determine their level of disease. In some instances, treatment can continue until a change (e.g., reduction) in the level of disease in the subject is detected. Upon improvement of a patient’s condition (e.g., a change (e.g., decrease) in the level of disease in the subject), a maintenance dose of a compound, or composition disclosed herein can be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, can be reduced, e.g., as a function of the symptoms, to a level at which the improved condition is retained.
Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.
The present disclosure is also described and demonstrated by way of the following examples.
However, the use of these and other examples anywhere in the specification is illustrative only and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to any particular preferred embodiment or aspect described herein. Indeed, many
modifications and variations may be apparent to those skilled in the art upon reading this specification, and such variations can be made without departing from the invention in spirit or in scope. The invention is therefore to be limited only by the terms of the appended claims along with the full scope of equivalents to which those claims are entitled.

Example 260. Bivalent compounds reduced P300 protein levels (Fig. 1).
LNCaP cells were treated with DMSO or indicated bivalent compounds at 5 nM for 6 hours. P300 protein levels were markedly reduced following treatment of some compounds as shown by
immunoblotting assays.
Example 261. Bivalent compounds concentration dependently reduced P300 protein levels (Fig.
2).
LNCaP cells were treated with bivalent compounds at indicated concentrations for 16 hours. Data showed that P300 proteins levels were reduced in a concentration-dependent manner. The concentrations required to reduce P300 by 50% (DC50) were below 5 nM for the selected compounds.
Example 262. Bivalent compounds rapidly reduced P300 protein levels (Fig. 3).
LNCaP cells were treated with selected bivalent compounds at 20 nM for indicated period of time. Data showed that P300 protein levels were significantly reduced as early as 2 hours following treatment.
Example 263. Bivalent compounds suppressed viability of LNCaP prostate cancer cells (Fig. 4).
LNCaP cells were treated with GNE-781 or selected bivalent compounds for 3 days at indicated concentrations following a 3-fold serial dilution. Data showed that cell viability was significantly reduced in the presence of bivalent compounds in a concentration-dependent manner.
Example 264. Bivalent compounds reduced P300/CBP protein levels (Fig. 5).
LNCaP cells were treated with DMSO or indicated bivalent compounds at 20 nM or 100 nM for 16 hours. P300/CBP protein levels were markedly reduced following treatment of some compounds as shown by immunoblotting assays.
Example 265. Bivalent compounds concentration-dependently reduced P300/CBP protein levels (Fig. 6).
LNCaP cells were treated with compounds at indicated concentrations for 6 hours. Data showed that P300/CBP proteins levels were reduced in a concentration-dependent manner. The concentrations required to reduce P300/CBP by 50% (DC50) were below 1 nM for the selected compounds.
Example 266. Bivalent compound-mediated degradation of P300 is dependent on the interaction with cereblon (Fig. 7).
LNCaP or 22RV1 cells were treated with various concentrations of P-100 or P-100-negative. The latter lost binding to cereblon (CRBN) due to a chemical modification. Data showed that P-100 reduced P300 protein levels in a concentration-dependent manner while P-100-neg had no effects on P300 protein levels.
Example 267. Bivalent compound-mediated degradation of P300/CBP is dependent on the ubiqutin-proteasome system (Fig. 8).
LNCaP cells were treated with a single dose of bivalent compounds, P-007, P-034 or P-100, or combination with pomalidomide, MG-132, Bortezomib, MLN4924. Data showed that bivalent compound- mediated degradation of P300/CBP is compromised by excessive CRBN ligand, pomalidomide, proteasome inhibitors, MG-132 or Bortezomib, or cullin E3 ligase inhibitor, MLN4924.
Example 268. Bivalent compounds reduced P300/CBP protien levels in 22RV1 subcutaneous xenograft tumors (Fig. 9).
Athymic nude mice bearing 22RV 1 subcutaneous xenograft tumors at the right flank were intraperitoneally or orally treated with selected bivalent compounds at 40 mg/kg.

Materials and Methods:
General Chemistry Methods:
All chemicals and reagents were purchased from commercial suppliers and used without further purification. FCMS spectra for all compounds were acquired using a Shimadzu FC-MS 2020 system or a Waters UPFC-MS H class system. The Shimadzu FC-MS 2020 system comprising a pump (FC-20AD) with degasser (DGU-20A3), an autosampler (SIF-20AHT), a column oven (CTO-20A) (set at 40 °C, unless otherwise indicated), a photo-diode array (PDA) (SPD-M20A) detector, an evaporative light- scattering (EFSD) (Alltech 3300EFSD) detector. Chromatography was performed on a Shimadzu SunFire
C 18 (5 mhi 50 * 4.6mm) with water containing 0.1% formic acid as solvent A and acetonitrile containing 0.1% formic acid as solvent B at a flow rate of 2.0 ml/min. Flow from the column was split to a MS spectrometer. The MS detector was configured with an electrospray ionization source. Nitrogen was used as the nebulizer gas. Data acquisition was performed with a Labsolution data system. The Waters UPLC- MS H class system comprising a pump (Quaternary Solvent Manager) with degasser, an autosampler (FTN), a column oven (set at 40 °C, unless otherwise indicated), a photo-diode array PDA detector.
Chromatography was performed on a AcQuity UPLC BEH C18 ( 1.7 pm 50 * 2.1mm) with water containing 0.1% formic acid as solvent A and acetonitrile containing 0.1% formic acid as solvent B at a flow rate of 0.6 mL/min. Flow from the column was split to a MS spectrometer. The MS detector was configured with an electrospray ionization source. Nitrogen was used as the nebulizer gas. Data acquisition was performed with a MassLynx data system. Proton Nuclear Magnetic Resonance ('H-NMR) spectra were recorded on a Bruker Avance III400 spectrometer. Chemical shifts are expressed in parts per million (ppm) and reported as d value (chemical shift d). Coupling constants are reported in units of hertz (/value, Hz; Integration and splitting patterns: where s = singlet, d = double, t = triplet, q = quartet, brs = broad singlet, m = multiple). Preparative HPLC was performed on Agilent Prep 1260 series with UV detector set to 254 nm or 220 nm. Samples were injected onto a Phenomenex Luna 75 x 30 mm, 5 pm,
C18 column at room temperature. The flow rate was 40 mL/min. A linear gradient was used with 10% (or 50%) of MeOH (A) in H20 (with 0.1 % TFA) (B) to 100% of MeOH (A). All compounds showed > 90% purity using the LCMS methods described above.
Cell Culture
LNCaP (clone FGC), 22RV1 and other cells were cultured at 37°C with 5% C02 in RPMI 1640 Medium supplemented with 10% fetal bovine serum. Cells were authenticated using the short tandem repeat (STR) assays. Mycoplasma test results were negative.
Antibodies and reagents
Rabbit anti-P300 antibody (86377S), anti-CBP antibody (7389S) and anti-vinculin antibody (18799S) were purchased from Cell Signaling Technology. HRP-conjugated anti-tubulin antibody was produced in house. Media and other cell culture reagents were purchased from Thermo Fisher Scientific. The
CellTiter-Glo Luminescent Assay kit was purchased from Promega.
Immunoblotting
Cultured cells or tissue chunks were washed with cold PBS once and lysed in cold RIPA buffer supplemented with protease inhibitors and phosphatase inhibitors (Beyotime Biotechnology). The solutions were then incubated at 4 °C for 30 minutes with gentle agitation to fully lyse cells. Cell lysates were centrifuged at 13,000 rpm for 10 minutes at 4 °C and pellets were discarded. Total protein concentrations in the lysates were determined by BCA assays (Beyotime Biotechnology). Cell lysates were mixed with Laemmli loading buffer to 1 X and heated at 99 °C for 5 min. Proteins were resolved on SDS-PAGE and visualized by chemiluminescence. Images were taken by a ChemiDoc MP Imaging system (Bio-Rad). Protein bands were quantitated using the accompanied software provided by Bio-Rad.
Cell viability assays
Cells were seeded at a density of 5000 cells per well in 96-well assay plates and treated with test compounds following a 12-point 3-fold serial dilution. Three days later, cell viability was determined using the CellTiter-Glo assay kit according to the manufacturer’s instructions. The dose-response curves were determined and IC50 values were calculated using the GraphPad Prism software following a nonlinear regression (least squares fit) method.
The LNCaP prostate cancer cell viability inhibition results and the percentage of inhibition of p300 of selected bivalent compound compounds are set forth in Tables 2 and 3 below.

The IC50 value of each compound was determined as described in Figure 4 and calculated using the GraphPad Prism 5.0 software.
Pharmacodynamic (PD) studies
All animal experiments were performed under protocols approved by the Institutional Animal Care and Use Committee (IACUC) of Cullgen. Athymic nude mice (male, 5-weeks old) received 5 million 22RV1 cells subcutaneously inoculated at the right flank site. Twenty days following inoculation, tumors were approximately 500 mm3 in size. Tumor-bearing mice were treated intraperitoneally or via oral gavage with vehicle or bivalent compounds at indicated doses. 6 hours after drug administration, animals were sacrificed, tumors were resected. Small chunks of tumors were homogenized for immunoblotting of P300/CBP and other proteins as indicated. Alternatively, ICR mice (male, 5-weeks old) were treated via oral gavage with vehicle or bivalent compounds at indicated doses. 6 hours after drug administration, animals were sacrificed, lung tissues were resected. Small chunks of lung tissues were homogenized for immunoblotting of CBP and other proteins as indicated.
