Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to U.S. Provisional Application No. 63 / 223,788, filed July 20, 2021, the entire contents of which are incorporated herein by reference. [Background technology]

[0002] Deubiquitinating enzymes (DUBs) have attracted significant attention as drug targets over the past 5–10 years. DUB inhibitors effectively promote the degradation of oncogenic proteins, especially those that are difficult to target directly because they are stabilized by DUB family members. Thus, highly optimized and well-characterized DUB inhibitors have become highly sought-after tools. However, most reported DUB inhibitors are combination drugs with weak (micromolar) potency against their primary targets, limiting their utility in target validation and mechanistic studies.

[0003] The DUB enzyme USP7 (ubiquitin-specific protease 7) has been shown to be involved in the regulation of numerous cellular processes including epigenetics, cell cycle, DNA repair, immunity, viral infection and tumor development. USP7, also known as herpesvirus-associated ubiquitin-specific protease (HAUSP), was first discovered as a protein that plays a role in the lytic propagation of viruses. Interest in this enzyme increased when USP7 was implicated in regulating the degradation of the tumor suppressor p53 by stabilizing MDM2, the major E3 ligase for p53.

[0004] Consistent with its regulation of diverse substrates and biological processes, USP7 has emerged as a drug target in a wide range of malignant tumors, including multiple myeloma, breast cancer, neuroblastoma, glioma, and ovarian cancer.However, known USP7 inhibitors have been shown to have modest potency against USP7 and low selectivity against other DUBs.In addition to modest potency and selectivity, the drawbacks of known USP7 inhibitor compounds include low solubility and general toxicity.Therefore, there is a need to develop more potent and selective irreversible USP7 inhibitors.

[0013] USP7 (ubiquitin-specific protease 7) / HAUSP (herpes-associated ubiquitin-specific protease) is a 135 kDa USP family protein. USP7 has been shown to interact with viral proteins such as ICP0 (Vmw110), a herpes simplex virus immediate early gene that stimulates the initiation of the viral lytic cycle, and EBNA1 (Epstein-Barr nuclear antigen-1). The DUB USP7 has been shown to be involved in the regulation of numerous cellular processes including epigenetics, cell cycle, DNA repair, immunity, viral infection, and tumorigenesis. Interest in this enzyme has increased when USP7 was implicated in regulating the degradation of the tumor suppressor p53 by stabilizing MDM2, the major E3 ligase for p53. Consistent with recent reports, USP7 silencing has also been shown to increase steady-state p53 levels by promoting the degradation of Mdm2. Binding of USP7 to p53 has recently been shown to be regulated by TSPYL5, a protein potentially involved in breast carcinogenesis through competition with p53 for binding to the same region of USP7. More recently, both up- and down-regulation of USP7 has been shown to inhibit colon cancer cell proliferation in vitro and tumor growth in vivo by resulting in constitutively high p53 levels.

[0049] How to use Ubiquitin is a 76-residue protein that is dynamically conjugated to proteins via isopeptide bonds. Canonically, the C-terminal glycine of ubiquitin is linked to the side chain of a substrate lysine, and ubiquitin can also be conjugated to substrates via the side chains of cysteine, serine, and threonine, as well as the N-terminal amine. McDowell, GS & Philpott, A. Non-canonical ubiquitylation: Mechanisms and consequences. Int. J. Biochem. Cell Biol. 45, 1833-1842 (2013). Ubiquitin itself has seven lysine side chains, and there are naturally occurring linear or mixed chains of ubiquitin conjugated through these lysine side chains or the N-terminal methionine residue. Ubiquitin conjugation is achieved by the coordinated action of ubiquitin-activating enzymes (E1), conjugating enzymes (E2), and ligases (E3) and can be reversed by deubiquitinating enzymes (DUBs).Monoubiquitin tags or ubiquitin chains of different topologies mediate protein conformational changes and binding to numerous scaffolding and adaptor proteins, and ubiquitination is involved in a number of key mechanisms of protein degradation (Nandi, D., et al., The Ubiquitin-Proteasome System. J Biosci 31, 137-155 (2016)), membrane trafficking (Hurley, JH & Stenmark, H. Molecular Mechanisms of Ubiquitin-Dependent Membrane Traffic. Annu. Rev. Biophys. 40, 119-142 (2011)), chromatin dynamics (Shilatifard, A. Chromatin Modifications by Methylation and Ubiquitination: Implications in the Regulation of Gene Expression. Annu. Rev. Biochem. 75, 243-269 (2006)), and DNA repair (Jackson, S. P. & Ubiquitin and SUMO play important roles in many cellular processes, including ubiquitin-dependent regulation of DNA damage responses (Durocher, D. Review Regulation of DNA Damage Responses by Ubiquitin and SUMO. Mol. Cell 49, 795-807 (2013)).Ubiquitin signaling is also implicated in cancer (Senft, D., Qi, J. & Ronai, ZAU biquitin ligases in oncogenic transformation and cancer therapy. Nat. Rev. Cancer 18, 69-88 (2018); Pinto-Fernandez, A. & Kessler, BMDU giving cancer: Deubiquitylating enzymes involved in epigenetics, DNA damage and the cell cycle as therapeutic targets. Front. Genet. 7, 1-13 (2016)), infection (Isaacson, MK & Ploegh, HL Ubiquitination, Ubiquitin-like Modifiers, and Deubiquitination in Viral Infection. Cell Host Microbe 5, 559-570 (2009)), and neurodegeneration (Ciechanover, A. & Brundin, P. The ubiquitin proteasome system in neurodegenerative diseases: sometimes the chicken, sometimes the egg.Neuron 40,427-446 The ubiquitin proteasome system in neurodeg(2003)) is also involved in a number of disease settings.In particular, the ubiquitin-proteasome system (UPS) has become a topic of interest in oncology, as both proteasome inhibitors and bivalent substrate-E3 ligands have been approved as targeted cancer therapies (Manasanch, EE & Orlowski, RZ Proteasome inhibitors in cancer therapy. Nat. Rev. Clin. Oncol. 14, 417-433 (2017); Bartlett, JB, et al. The evolution of thalidomide and its IMiD derivatives as anticancer agents. Nat. Rev. Cancer 4, 314-322 (2004)). Currently, there are no DUB inhibitors in the clinic, a reality driven in part by the lack of high-quality probe compounds to address both fundamental DUB biology exploration and target validation in preclinical disease models.

[0050] There are approximately 100 human DUBs that belong to seven different families, six of which are cysteine ​​proteases (ubiquitin-specific proteases [USPs], ubiquitin C-terminal hydrolases [UCHs], ovarian tumor proteases [OTUs], Josephin, Mindy, and ZUFSPs), and one of which is a family of zinc metalloproteases (JAB / MPN / MOV34 [JAMM / MPN]). Recently, several high-quality probes targeting USP7 have been developed. These probes share the properties of single- or double-digit nM potency against USP7, co-structural confirmation of USP7 catalytic domain binding, and activity profiling that validates selectivity against over 40 DUBs. Lamberto, I. et al. Structure-Guided Development of a Potent and Selective Non-covalent Active-Site Inhibitor of USP7. Cell Chem. Biol. 24, 1490-1500 (2017), Kategaya, L. et al. USP7 small-molecule inhibitors interfere with ubiquitin binding. Nature 550, 534-538 (2017), Turnbull, AP et al. Molecular basis of USP7 inhibition by selective small-molecule inhibitors. Nature 550, 481-486 (2017), and Gavory, G. et al. Discovery and characterization of highly potent and selective allosteric USP7 inhibitors. 7, (2017). Taken together, this work represents a remarkable shift in thinking about the druggability of USP7 and DUBs more broadly. Prior to 2017, there were no USP:small molecule co-crystal structures published in the Protein Data Bank (PDB), and studies reporting DUB profiling consistently found that previously reported DUB inhibitors typically had weak affinities (above 1 μM) and lacked a high degree of selectivity among DUBs.Ritorto,M.S.et al.Screening of DUB activity and specificity by MALDI-TOF mass spectrometry.Nat.Commun.5,4763(2014)。

[0051] USP7 is one of the most widely studied DUBs and has been linked to multiple substrates, cellular pathways, and pathologies. USP7 was first discovered as an interaction partner and stabilizer of the herpesvirus E3 ligase ICP0. Everett,RD et al.A novel ubiquitin-specific protease is dynamically associated with the PML nuclear domain and binds to a herpesvirus regulatory protein.16,1519-1530(1997). Since then, USP7 has also been linked to MDM2 (Li, M., et al. A dynamic role of HAUSP in the p53-Mdm2 pathway. Mol. Cell 13,879-886 (2004)), UHRF1 (Ma, H. et al. stability.Proc.Natl.Acad.Sci.109,4828-4833(2012)), TRIM27(Zaman,MM-U.et al.Ubiquitination-Deubiquitination by the TRIM27-USP7 Complex Regulates Tumor Necrosis Factor Alpha-Induced Apoptosis.Mol.Cell.Biol.33,4971-4984(2013)), RING1B(de Bie,P.et al.Regulation of the Polycomb protein RING1B ubiquitination by USP7.Biochem.Biophys.Res.Commun.400,389-395(2010)), RAD18(Zlatanou,A.et al.USP7 is essential for maintaining Rad18 stability and DNA damage tolerance.35,965-976(2015)), RNF220(Ma,P.et al.The Ubiquitin Ligase RNF220 Enhances Canonical Wnt Signaling through USP7-Mediated Deubiquitination of -Catenin.Mol.Cell.Biol.34,4355-4366(2014)), MARCH7(Nathan,JAet al.The ubiquitin E3 ligase MARCH7 is differentially regulated by the deubiquitylating enzymes USP7 and USP9X.Traffic 9,1130-1145(2008)), RNF168(Zhu,Q.,Sharma,N.,He,J.,Wani,G.& Wani,AAUSP7 deubiquitinase promotes ubiquitin-dependent DNA damage signaling by stabilizing RNF168.Cell Cycle 14,1413-1425(2015)), and RNF169 (An,L.et al.Dual-utility NLS drives RNF169-dependent DNA damage responses.Proc.Natl.Acad.Sci.114,E2872-E2881(2017)). Furthermore, USP7 has been found in a binary complex with both GMP and UVSSA, and binding of USP7 appears to be essential for the cellular function of these proteins. Van Der Knaap,JAet al.GMP synthetase stimulates histone H2B deubiquitylation by the epigenetic silencer USP7.Mol.Cell 17,695-707(2005), Schwertman,P.et al.UV-sensitive syndrome protein UVSSA recruits USP7 to regulate transcription-coupled repair.Nat.Genet.44,598-602(2012)。.

[0052] Of all these possible substrates, the interaction of USP7 with MDM2 has attracted the most interest from a mechanistic and therapeutic point of view. USP7 has been shown to bind both MDM2 and p53 via its TRAF domain and to have DUB activity for both of these proteins. A new hypothesis has emerged in which USP7 functions as a molecular switch, whereby USP7 deubiquitinates and stabilizes MDM2 during normal cell proliferation, but in the presence of cellular stress signals, its preferred substrate shifts to p53. Brazhnik, P. & Kohn, KW A USP-regulated switch from auto- to p53 ubiquitination by Mdm2 (in silico discovery). Math. Biosci. 210, 60-77 (2007); Kim, RQ & Sixma, TK Regulation of USP7: A high incidence of E3 complexes. J. Mol. Biol. 429, 3395-3408 (2017). Given the important role of p53 in tumor suppression, USP7 has been proposed as a therapeutic target in TP53-WT tumors, with a putative mechanism of action involving increased p53 protein levels, similar to the effects of RG-7388, an MDM2-p53 interaction inhibitor, and ATSP-7041, an MDM2 / MDM4 dual inhibitor (both currently in clinical trials). Ding, Q. et al. Discovery of RG7388, a potent and selective p53-MDM2 inhibitor in clinical development. J. Med. Chem. 56, 5979-5983 (2013); Chang, YSet al. Stapled α-helical peptide drug development: A potent dual inhibitor of MDM2 and MDMX for p53-dependent cancer therapy. Proc. Natl. Acad. Sci. 110, E3445-E3454 (2013).However, given that USP7 targets multiple substrates, there is much debate about the relative importance of p53 mutation status in predicting response to USP7 inhibition. Several previous studies on nonselective USP7 inhibitors have shown that USP7 inhibitors are effective against both p53 WT and mutant disease. Chauhan, D. et al.Article A Small Molecule Inhibitor of Ubiquitin-Specific Protease-7 Induces Apoptosis in Multiple Myeloma Cells and Overcomes Bortezomib Resistance.Cancer Cell 22, 345-358(2012), Wang, M. et al.The USP7 Inhibitor P5091 Induces Cell Death in Ovarian Cancers with Different P53 Status.Cell.Physiol.Biochem.43, 1755-1766(2018). These results are supported by studies using Genentech's DUB-selective USP7 inhibitor, GNE-6640, which did not produce significantly different responses in TP53-WT or mutant cell lines when screened in a panel of 181 cells. Kategaya, L. et al. USP7 small-molecule inhibitors interfere with ubiquitin binding. Nature 550, 534-538 (2017). On the other hand, for the selective USP7 inhibitor, compound 42, TP53 status has been found to be a significant predictor of response in Ewing's sarcoma and other cancer cell types. Roti, G. et al., J. Exp. Med., 215, 197-216 (2018).

[0053] One of the major missing pieces in previous reports of selective USP7 inhibitors was the spectrum of off-targets outside the DUB family. A well-annotated off-target profile would help clarify whether the p53-independent effects of USP7 inhibitors are due to other USP7 substrates or other compound targets. Based on the structure of compound 42 bound to the catalytic domain of USP7, we designed a rational synthesis of an irreversible, affinity-tagged analogue that would be sufficient for proteome-wide profiling experiments and follow-up studies on USP7 / p53 biology.

[0054] USP7 also alters the levels of p16INK4a tumor suppressor via Bmi1 / Mel18 stabilization. Maertens et al., EmboJ.29,2553-2565(2010). Additional proteins involved in genome integrity / regulation, such as DNMT1 DNA methylase and claspin adaptor, are also stabilized by USP7. Du et al., Science Signaling,3(146):ra80(2010); Faustrup et al., J.Cell Biol.,184(1):13-9(2009). Importantly, the abundance of USP7 and DNMT1, proteins involved in maintaining epigenetic methylation required to repress the expression of genes involved in development and cancer, correlates in human colon cancer (Du et al.,2010). USP7 has also been shown to deubiquitinate PTEN, a well-known tumor suppressor gene, in human cells, which induces its nuclear export and thus its inactivation. Song et al., Nature, 455(7214), 813-7(2008). More importantly, overexpression of USP7 was first reported in prostate cancer, and this overexpression was directly associated with tumor invasiveness (Song et al., 2008).

[0055] Recently, the methyltransferase PHF8 (Wang et al., 2016a), the demethylase DNMT1 (Du et al., 2010; Felle et al., Nucleic Acids Res, 39, 8355-65, 2011; Qin et al., J Cell Biochem, 112, 439-44, 2011), and the acetyltransferase Tip60 (Dar et al., Mol Cell Biol, 33, 3309-20, 2013), as well as H2B itself (van der Knaap et al., Mol Cell, 17, 695-707, 2005), have been identified as direct targets of USP7. Other notable targets of USP7 include FOXP3, a transcription factor that links this DUB enzyme to immune responses in Treg cells (van Loosdregt et al., Immunity, 39, 259-71, 2013), and N-Myc, which is stabilized in neuroblastoma cells (Tavana et al., Nat Med, 22, 1180-1186, 2016). Consistent with its regulation of diverse substrates and biological processes, USP7 has emerged as a drug target in a wide range of malignancies, including multiple myeloma (Chauhan et al., Cancer Cell, 22, 345-58, 2012), breast cancer (Wang et al., 2016a), neuroblastoma (Tavana et al., 2016), glioma (Cheng et al., Oncol Rep, 29, 1730-6, 2013), and ovarian cancer (Zhang et al., Tohoku J Exp Med, 239, 165-75, 2016). USP7 has also been shown to deubiquitinate FOXO4 in human cells, inducing its nuclear export and thus its inactivation, resulting in activation of the oncogenic PI3K / PKB signaling pathway (van der Horst et al., Nat Cell Biol. 2006, 8, 1064-1073).Finally, USP7 plays an important role in the p53-mediated cellular response to various types of stress, such as DNA damage and oxidative stress (Marchenko et al., Embo J. 2007 26, 923-934; Meulmeester et al., Mol Cell 2005, 18, 565-576.; van der Horst et al., Nat Cell Biol. 2006, 8, 1064-1073).

[0056] Multiple myeloma (MM) is an incurable hematological malignancy characterized by the accumulation of abnormal plasma cells in the bone marrow, which interferes with the production of normal blood cells. The average survival rate of MM patients has improved in recent years as a result of the introduction of proteasome inhibitors and immunomodulatory agents into the treatment regimen, but it remains quite low, at only 5 years. The proteasome inhibitor bortezomib validates the validity of the ubiquitin proteasome system as a therapeutic target for MM drug development. USP7 is a therapeutic target in MM due to its role in the degradation of p53. USP7 is highly expressed in tumor cells of MM patients and in MM cell lines compared to normal bone marrow cells. Mutations or deletions in TP53 are late events in MM, suggesting that increasing p53 through pharmacological inhibition of USP7 may be an effective treatment strategy for this malignancy.

[0057] Ewing sarcoma is a rare type of cancer that begins in the bone or the soft tissue surrounding the bone. Ewing sarcoma is more common in adolescents and young adults. The current standard treatment for Ewing sarcoma is chemotherapy, radiation therapy, and surgery.

[0128] The term "prodrug" is intended to include compounds that are converted to the therapeutically active agent of the present invention (e.g., a compound of formula I) under physiological conditions. A common method for making a prodrug is to include one or more selected moieties that are hydrolyzed under physiological conditions to reveal the desired molecule. In other embodiments, the prodrug is converted by the enzymatic activity of the subject. For example, esters or carbonates (e.g., esters or carbonates of alcohols or carboxylic acids) are preferred prodrugs of the present invention. In certain embodiments, some or all of the compounds of formula I in the formulations depicted above can be replaced with the corresponding suitable prodrugs, for example, hydroxyls in the parent compound are presented as esters, or carbonates or carboxylic acids present in the parent compound are presented as esters.

[0129] The present invention includes all pharma- ceutically acceptable isotopically labeled compounds described herein in which one or more atoms are replaced with an atom having the same atomic number, but an atomic mass or mass number different from that usually found in nature. In certain embodiments, the compounds of the present invention are enriched with such isotopically labeled materials (e.g., compounds in which the isotopic distribution of the compound in the composition differs from the natural or typical distribution of isotopes).

[0130] Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, e.g. 2 H and 3 H, isotopes of carbon, e.g. 11 C. 13 C and 14 C, an isotope of chlorine, e.g. 36 Cl, an isotope of fluorine, e.g. 18 F, an isotope of iodine, e.g. 123 I and 125 I, an isotope of nitrogen, e.g. 13 N and 15 N, isotopes of oxygen, e.g. 15 O. 17 O and 18 O, isotopes of phosphorus, e.g. 32 P, as well as sulfur isotopes, e.g.35 Examples include S.

The radioactive isotope tritium, i.e. 3 H, and carbon-14, i.e. 14 C are useful for this purpose given their ease of incorporation and ready means of detection.

[0132] Deuterium, i.e. 2 Substitution with heavier isotopes, such as H, can offer certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and therefore may be preferred in some circumstances.

[0134] The compounds of the present invention may have one or more asymmetric carbon atoms and may exist in the form of optically pure enantiomers, mixtures of enantiomers, such as racemates, optically pure diastereomers, mixtures of diastereomers, racemates of diastereomers, or racemic mixtures of diastereomers. Optically active forms can be obtained, for example, by resolution of racemates, by asymmetric synthesis or asymmetric chromatography (chromatography using chiral adsorbents or eluents). That is, certain of the disclosed compounds may exist in various stereoisomeric forms.

[0135] Stereoisomers are compounds that differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are non-superimposable, most commonly because they contain an asymmetrically substituted carbon atom that serves as a chiral center. "Enantiomer" means one of a pair of molecules that are mirror images of each other and are non-superimposable. "Diastereomers" are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms and represent the configuration of substituents around one or more chiral carbon atoms. Enantiomers of a compound can be prepared, for example, by separating the enantiomer from a racemate using one or more well-known techniques and methods, such as chiral chromatography and separation methods based thereon. Suitable techniques and / or methods for separating enantiomers of the compounds described herein from racemic mixtures can be readily determined by one of ordinary skill in the art.

[0136] "Geometric isomer" means an isomer that differs in the orientation of substituent atoms in relationship to a carbon-carbon double bond, a cycloalkyl ring, or a bridged bicyclic system. The atoms (other than H) on each side of the carbon-carbon double bond can be in the E (substituents are on opposite sides of the carbon-carbon double bond) or Z (substituents are oriented on the same side) configuration. "R", "S", "S*", "R*", "E", "Z", "cis", and "trans" indicate configurations relative to the core molecule. Some of the disclosed compounds can exist in atropisomeric forms. Atropisomers are stereoisomers that result from hindrance of rotation about a single bond, where the steric strain barrier to rotation is high enough to allow separation of the conformers. The compounds of the present invention can be prepared as individual isomers by isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include forming salts of the free bases of each isomer of the isomeric pair using optically active acids (followed by fractional crystallization and regeneration of the free bases), forming salts of the acid forms of each isomer of the isomeric pair using optically active amines (followed by fractional crystallization and regeneration of the free acids), forming esters or amides of each isomer of the isomeric pair using optically pure acids, amines or alcohols (followed by chromatographic separation and removal of the chiral auxiliary), or resolving isomeric mixtures of either the starting materials or the final products using a variety of well-known chromatographic methods.

[0137] Diastereomeric purity is the ratio of the weight of one diastereomer or the ratio of the weight of all diastereomers. When the stereochemistry of the disclosed compounds is named or depicted by structure, the named or depicted stereoisomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% by weight relative to the other stereoisomer. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% optically pure by weight. When a single diastereomer is named or depicted by structure, the depicted or named diastereomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% pure by weight. The percentage of optical purity is the ratio of the weights of the enantiomers to the sum of the weight of the enantiomer and the weight of its optical isomer.

[0138] The percent purity by mole fraction is the ratio of moles of an enantiomer (or diastereomer) or the ratio to the sum of the moles of an enantiomer (or diastereomer) and its optical isomer. When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% pure by mole fraction compared to other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% pure by mole fraction. When a single diastereomer is named or depicted by structure, the depicted or named diastereomer is at least about 60%, about 70%, about 80%, about 90%, about 99%, or about 99.9% pure by mole fraction.

[0139] When a disclosed compound is named or depicted by structure without indicating stereochemistry, and the compound has at least one chiral center, the name or structure should be understood to encompass either an enantiomer of the compound without the corresponding optical isomer, a racemic mixture of the compound, or a mixture enriched in one enantiomer compared to the corresponding optical isomer. When a disclosed compound is named or depicted by structure without indicating stereochemistry, and the compound has two or more chiral centers, the name or structure should be understood to encompass a diastereomer without the other diastereomer, some diastereomers without other diastereomeric pairs, a mixture of diastereomers, a mixture of diastereomeric pairs, a mixture of diastereomers enriched in one diastereomer compared to the other diastereomer(s), or a mixture of diastereomers enriched in one or more diastereomers compared to the other diastereomers. The present invention encompasses all of these forms.
