AI Technical Summary
The existing BCL-2 inhibitors have weakened their effects in the face of BCL-2 mutations, and have side effects such as thrombocytopenia caused by excessive inhibition of BCL-XL, and drug interactions are at risk by inhibiting drug metabolism.
A new class of BCL-2 inhibitors have been developed, which have a high selectivity for BCL-2 protein, limited affinity for BCL-XL, which can effectively inhibit BCL-2 mutant proteins and reduce the risk of drug interactions by limiting the inhibition of CYP3A4.
These novel inhibitors showed strong antitumor activity in experiments, were able to induce apoptosis of cancer cells and exhibited fewer thrombocytopenia side effects in animal models, while reducing the risk of interaction with other drugs.

[0001] FIELD OF THE INVENTION The present invention relates to 5-[7-(3,4-dihydro-1H-isoquinoline-2-carbonyl)-1,2,3,4-tetrahydroisoquinolin-6-yl]-1H-pyrrole-3-carboxamide derivatives, pharmaceutical compositions containing them, and their use as pro-apoptotic agents. The compounds of the present invention inhibit the activity of Bcl-2 protein and may be of interest in the treatment of cancer, immune disorders, and autoimmune diseases.
[0002] Background of the Invention Apoptosis, or programmed cell death, is a physiological process important for embryonic development and the maintenance of tissue homeostasis. Apoptotic cell death involves not only morphological changes, such as nuclear condensation and DNA fragmentation, but also biochemical events, such as caspase activation, which damages important structural components of the cell, leading to its degradation and death. Regulation of the apoptotic process is complex and involves the activation or suppression of multiple intracellular signaling pathways (Cory S. et al., Nature Review Cancer, 2002, 2, 647-656). Deregulation of apoptosis is involved in certain pathologies. Therefore, lack of apoptosis is one of the phenotypic characteristics of cancer (Hanahan D. et al., Cell 2000, 100, 57-70). Anti-apoptotic proteins of the Bcl-2 family are associated with numerous pathologies. The involvement of Bcl-2 family proteins has been described in numerous types of cancer, including colon cancer, breast cancer, small cell lung cancer, non-small cell lung cancer, bladder cancer, ovarian cancer, prostate cancer, chronic lymphocytic leukemia, follicular lymphoma, myeloma, and prostate cancer. Overexpression of anti-apoptotic proteins of the Bcl-2 family is associated with tumorigenesis, resistance to chemotherapy, and poor clinical prognosis in cancer-affected patients. Therefore, there is a therapeutic need for compounds that inhibit the anti-apoptotic activity of Bcl-2 family proteins. Venetoclax (also known as ABT-199) is a selective Bcl-2 inhibitor that disrupts the interaction of Bcl-2 with BH3-only proteins, thereby inducing apoptosis. Venetoclax is approved in combination with azacitidine, decitabine, or low-dose cytarabine for the treatment of (i) adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) with or without 17p deletion who have received at least one prior therapy and (ii) adults aged 75 years or older with newly diagnosed acute myeloid leukemia (AML) or who have other medical conditions that prevent the use of standard chemotherapy.However, a significant number of relapses are observed in CLL, suggesting the emergence of acquired resistance mechanisms. Target mutations have been shown to cause resistance in other high-affinity targeted therapies (Garraway & Janne, Cancer Discovery 2012, 2, 214-226). Mutations in Bcl-2 affecting its hydrophobic groove have been identified in various venetoclax-resistant leukemia and lymphoma cell lines (Fresquet et al., Blood 2014, 123, 4111-4119; Tahir et al., BMC Cancer 17:399). Recently, a single mutation in Bcl-2 (a substitution of glycine at position 101 with valine: Gly101Val) was identified in CLL samples from patients resistant to venetoclax and therefore demonstrated clinical relevance. This Gly101Val (also called G101V) mutation has been associated with reduced binding of venetoclax to the hydrophobic groove of Bcl-2 and resistance to venetoclax (Blombery et al., Cancer Discovery 2019, 9, 342-353). Following the identification of G101V, multiple other mutations in the BCL-2 protein were identified in patients treated with venetoclax for CLL (e.g., D103Y, D103V, D103E, F104I, F104L, D111A, A113G, R129L, V156D; Blombery et al., Blood 2020, 5;135(10):773-777). D103E and V156D have also been detected in relapsed and refractory mantle cell lymphoma after sequential venetoclax / zanubrutinib monotherapy (Thompson et al., Blood 2022, 25;6(2):503-508). An acquired BCL-2 mutation (D111A) has also been reported in a patient with multiple myeloma treated with venetoclax (Neri et al., Blood, 134 (Supplement_1):572). F104I has also been reported in a patient with follicular lymphoma (Blombery et al., Br J Hematol 2019, 186, pp. e188-e191).Based on these clinical data, there is a need to identify novel therapeutic agents that can be used to treat patients with cancers that harbor BCL-2 mutations after treatment with venetoclax, particularly those who are refractory and relapsed.
[0003] The development of BCL-2-selective inhibitors is complicated by the high similarity between BCL-2 and BCL-XL within the BH3-binding domain (Petros et al., Proc. Natl. Acad. Sci. USA 2001, 98, 3012-3017). In addition, BCL-XL has previously been established as a key survival factor for platelets (Zhang et al., Cell Death Diff 2007, May;14(5):943-51; Mason et al., Cell 2007, 23;128(6):1173-86). Genetic ablation, hypomutation, or pharmacological inhibition of BCL-XL results in a shortened platelet half-life and dose-dependent thrombocytopenia in vivo. Early signs of clinical antitumor activity have been observed with the dual BCL-2 / BCL-XL inhibitor (ABT263, navitoclax) in lymphoid malignancies thought to be dependent on BCL-2 for survival (Wilson et al., Lancet Oncol 2010, Dec;11(12):1149-59). As predicted by preclinical data, inhibition of BCL-XL by navitoclax induces a rapid, concentration-dependent decrease in circulating platelet counts. This mechanism-based thrombocytopenia is a dose-limiting toxicity of navitoclax monotherapy in patients, limiting the ability to increase drug concentrations to highly effective ranges. Consequently, minimizing BCL-XL affinity is also necessary to design drugs with favorable efficacy and tolerability profiles.
[0004] Finally, CYP450-mediated metabolism is the primary excretion pathway for many drugs, leading to frequent drug interactions due to inhibition of drug metabolism (Deodhar et al., Pharmaceutics 2020, 4;12(9):846). Among CYP450s, CYP3A4 is the most abundant in the human liver (approximately 40%) and metabolizes over 50% of clinically used drugs. Therefore, drugs that inhibit CYP3A4 may increase the exposure of co-administered drugs, potentially causing serious drug toxicity (Zhou et al., Ther Clin Risk Manag 2005, Mar;1(1):3-13). This issue must also be addressed in the drug discovery process to mitigate the risk of CYP3A4-mediated drug-drug interactions.
[0005] Here, we claim the discovery of next-generation BCL-2 inhibitors that are selective for BCL-2 protein and have limited on-target affinity for BCL-XL and thrombocytopenia, but are highly active against wild-type BCL-2 protein and exhibit a favorable selectivity profile against various BCL-2 mutations that emerge clinically following venetoclax treatment. The identified compounds also demonstrated limited inhibition of CYP3A4.
[0006] Summary of the Invention The present invention provides potent, selective Bcl-2 inhibitors represented by Formula (I), as defined below. The inventors have demonstrated that these compounds have strong binding affinity to the Bcl-2 wild-type receptor and a panel of Bcl-2 mutants. The compounds of the present invention demonstrate overall better on-target affinity for Bcl-2 proteins compared to Bcl-xL proteins. The inventors have also demonstrated that compounds represented by Formula (I) have a cytotoxic profile in cell lines overexpressing Bcl-2 wild-type or Bcl-2 mutants. Furthermore, compounds represented by Formula (I) can induce apoptosis in cancer cells in vivo and trigger tumor regression in mice. Finally, limited platelet reduction was observed in animals highly exposed to the exemplary compounds. Furthermore, the exemplary compounds also demonstrated limited inhibitory potential against CYP3A4. Based on their pro-apoptotic properties, the compounds of the present invention can be used to treat conditions involving deregulation of apoptosis, such as cancer, autoimmune diseases, and immune system disorders.

In further embodiments, compounds of the present invention also exhibit overall better on-target affinity for Bcl-2 wild-type protein and Bcl-2 mutants compared to Bcl-xL protein. In some embodiments, the Bcl-2 mutant (also referred to as a BCL2 mutein) is selected from the following group: BCL2 G101V, BCL2 D103Y, BCL2 F104I, BCL2 D111A, BCL2 D103E, BCL2 A113G, BCL2 R129L, BCL2 V156D, BCL2 D103V, and BCL2 F104L.
[0060] In some embodiments of the present disclosure, compounds of the present invention are highly active against BCL2 wild-type protein (i.e., values less than 100 pM in the TR-FRET assay for EKI_BCL2 wild-type), while exhibiting limited on-target affinity for BCL-XL (i.e., [EKI_BCL-XL] / [EKI_BCL2 wild-type] selectivity ratio greater than 100).
[0061] The present invention also relates to pharmaceutical compositions comprising at least one compound of formula (I) or its addition salt with a pharmaceutically acceptable acid or base, in combination with one or more pharmaceutically acceptable excipients. In particular, these pharmaceutical compositions are of interest as anti-apoptosis inhibitors, especially for the treatment of cancer (hematological malignancies and solid tumors) and autoimmune and immune system diseases. In particular, these pharmaceutical compositions are of interest as anti-apoptosis inhibitors in the treatment of cancer chemotherapy resistance or radioresistance. Preferably, these pharmaceutical compositions can be used for the treatment of cancers (hematological malignancies and solid tumors) selected from myeloma, in particular multiple myeloma, lymphoma, in particular non-Hodgkin's lymphoma (NHL) and diffuse large B-cell lymphoma (DLBCL), leukemia, in particular chronic lymphocytic leukemia (CLL), T-cell acute lymphoblastic leukemia (T-ALL), B-cell acute lymphoblastic leukemia (B-ALL) and acute myeloid leukemia (AML), cancer of the bladder, brain, breast, uterus, esophagus and liver, colorectal cancer, kidney cancer, melanoma, ovarian cancer, prostate cancer, pancreatic cancer, lung cancer, in particular non-small cell lung cancer and small cell lung cancer, rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE), as well as autoimmune diseases and diseases of the immune system. In some embodiments, the compounds of Formula (I) are used in the manufacture of medicaments for use in the treatment of cancer and autoimmune and immune system diseases.

[0063] In another embodiment, the compounds of the present invention can be used in combination with radiation therapy in the treatment of cancer.
[0064] Alternatively, the compounds of the present invention can be linked to a monoclonal antibody. Antibody-drug conjugates (ADCs) represent a new class of therapeutic agents formed by chemically linking a cytotoxic drug to a monoclonal antibody via a linker. The monoclonal antibody of an ADC selectively binds to a target antigen in a cell (e.g., a cancer cell) and releases the drug intracellularly. ADCs have therapeutic potential because they combine the specificity of an antibody with the cytotoxicity of a drug. Nevertheless, to date, the development of ADCs as therapeutic agents has met with limited success due to various factors, such as unfavorable toxicity profiles, low efficacy, and poor pharmacological parameters. Therefore, there remains a need for novel ADCs that can overcome these problems and selectively deliver Bcl-2 to target cancer cells.
[0065] In another embodiment, the compounds of the present invention can be linked to fragments of monoclonal antibodies or to scaffold proteins that may or may not be related to monoclonal antibodies. Antibody fragments are understood to be fragments of the Fv, scFv, Fab, F(ab')2, F(ab'), scFv-Fc type or diabodies, which generally have the same binding specificity as the antibody from which they are derived. According to the present invention, antibody fragments of the present invention can be obtained starting from antibodies by cleavage of disulfide bridges by methods such as digestion with enzymes, for example, pepsin or papain, and / or chemical reduction. Alternatively, antibody fragments encompassed by the present invention can be obtained by genetic recombination techniques also well known to those skilled in the art or by other methods, such as peptide synthesis using automated peptide synthesizers, for example those supplied by Applied Biosystems.
[0066] Scaffold proteins, which may or may not be related to monoclonal antibodies, are understood to mean proteins that may or may not contain an immunoglobulin fold and that provide binding capacities similar to those of monoclonal antibodies. Those skilled in the art know how to select protein scaffolds. It is known, inter alia, that such scaffolds to be selected should exhibit several characteristics (Skerra, J. Mol. Recogn. 2000, 13, 167-187): good phylogenetic conservation, a robust structure with a known three-dimensional molecular organization (e.g., crystallography or NMR), small size, no or only few post-translational modifications, and ease of production, expression, and purification. Such protein scaffolds may be structures selected from the group consisting of, but are not limited to, fibronectin and preferentially the tenth fibronectin type III domain (FNfn10), lipocalins, anticalins (Skerra, J. Biotechnol. 2001, 74, 257-75), protein Z derivatives derived from domain B of staphylococcal protein A, thioredoxin A, or any protein with a repeat domain, such as ankyrin repeats (Kohl et al., PNAS 2003, 100, 1700-1705), armadillo repeats, leucine-rich repeats, or tetratricopeptide repeats. Mention may also be made of scaffold derivatives derived from venoms (such as those of scorpions, insects, plants, or mollusks) or protein inhibitors of neuronal nitric oxide synthase (PIN).
