Description

Title of Invention: SULFONAMIDE OR SULFINAMIDE COMPOUND HAVING EFFECT OF INDUCING BRD4 PROTEIN DEGRADATION AND PHARMACEUTICAL USE THEREOF [Technical Field]

[0001] The present invention relates to a sulfonamide or sulfinamide compound or a pharmaceutically acceptable salt thereof, which is superior in a cytotoxic action on cancer cells, an action inducing degradation of BRD4 protein in cancer cells, and an inhibitory action on the binding of BRD4 protein and acetylated histone, and useful as an anticancer drug, a BRD4 protein degradation inducing agent or a BRD4 protein inhibitor. [Background Art]

[0002] Eukaryotic DNA forms a chromatin structure and is stored in the nucleus. Nucleosome which is a constitutional unit thereof has a structure in which DNA is wound around histone octamer formed by 2 molecules each of 4 kinds of histones, H2A, H2B, H3, H4. Dozens of residues on the N-terminal side of histones is called a histone tale, and various post-translational modifications such as acetylation, methylation, phosphorylation, ubiquitination are present therein. Post-translational modification, also called histone code, is one of the mechanisms responsible for controlling epigenetic gene expression, which determines when or where genetic information on DNA is expressed. Histone modification is reversible, and functionally controlled by a modifying enzyme (writer) that writes modification group into histone, a demodifying enzyme (eraser) that removes modification group, and a histone reader (reader) that specifically reads modified histone. It is known that such control mechanism greatly contributes to ontogenesis and cell differentiation, while epigenetics abnormalities are involved in various diseases.

[0003] The bromodomain is a reader protein consisting of about 110 amino acids that recognize acetylated lysine of histone. About 50 kinds of proteins possessing a bromodomain have been known to date, and they function as scaffold proteins for various transcription factors by binding to acetylated lysine of histone and also show various functions in the cell such as being responsible for chromatin reconstitution and transcriptional regulation through its own histone acetyltransferase activity and kinase activity and the like. BRD2, BRD3, BRD4 and BRDT contained in the BET (bromodomain and extraterminal) family protein of the bromodomain-containing protein (sometimes to be indicated as BET protein in the present specification and Claims) possess two highly conserved bromodomains on the N-terminal side and Extra C-Terminal domain on the C-terminal side within the family, and respective BET proteins are known to function both independently and cooperatively (non-patent document 1).

[0004] Among the BET family proteins, BRD4 is expected to be the target of drug discovery in cancer treatment because it regulates the expression of c-MYC which is a proto-oncogene (non-patent document 2) and has been reported to have a correlation with prognosis in various carcinomas such as gastric cancer (non-patent document 3), ovarian cancer (nonpatent document 4), lung cancer (non-patent document 5), liver cancer (non-patent document 6), urothelial cancer (non-patent document 7), testicular cancer (non-patent document 8), skin cancer (non-patent document 9), prostate cancer (non-patent document 10), breast cancer (non-patent document 11), colorectal cancer (non-patent document 12) and leukemia (nonpatent document 13).

[0005] To date, a BRD4 inhibitor that inhibits the binding of BRD4 to histone has been clinically developed as an anticancer drug targeting BRD4 (non-patent document 14). However, BRD4 inhibitors do not show a sufficient effect since they cause accumulation of BRD4 (non-patent document 15), and resistance is acquired by expression of proteins that stabilize BRD4 expression and proteins that enhance BRD4-mediated transcriptional activity in a bromodomain-independent manner (non-patent documents 16, 17). Thus, the development of an anticancer drug targeting BRD4 by a new means is required.

[0006] In recent years, a technology in which an artificial complex of E3 ligase and a target protein is formed in the cell by using a compound in which a ligand for an E3 ligase [Von Hippel-Lindau (VHL), Cereblon (CRBN), Cellular Inhibitor of Apoptosis Protein 1 (cIAP1)] having ubiquitin ligase activity and a binder that binds to the target protein are linked, and degradation of the target protein is induced by using the ubiquitin-proteasome system, which is an intracellular protein degradation mechanism (chemical knockdown) has been attracting attention as a new drug discovery technique (non-patent document 18). ARV-771 utilizing a ligand for VHL, ARV-825 utilizing a ligand for CRBN and the like have heretofore been reported as BRD4 protein degradation inducing agents utilizing this technique (non-patent documents 15, 19).

[0007] In cancer chemotherapy, the emergence of natural tolerance that renders anticancer drugs ineffective from the beginning of treatment and acquired resistance that decreases the effect of anticancer drugs when they are used continuously for a long period of time has become a major issue (non-patent document 20). It is expected that the treatment results of cancer chemotherapy will be improved by overcoming the resistance to anticancer drugs, and the existence of various resistance mechanisms has been clarified so far (non-patent document 20). Regarding BRD4 protein degradation inducing agents, it has been reported that acquired resistance is induced in cancer cells due to the dysfunction of the complex of E3 ligase VHL or CRBN that causes proteolysis action (nonpatent document 21). In tumors such as renal cell cancer and the like caused by mutation in the VHL gene (non-patent document 22), it is considered that natural resistance to BRD4 protein degradation inducing agents using a ligand for VHL occurs, and the development of a novel BRD4 protein degradation inducing agent that uses a new ligand for E3 ligase and overcomes the resistance to the conventional BRD4 protein degradation inducing agents is desired. In recent years, many target protein degradation inducing compounds have been reported in which a new ligand for E3 ligase and a binder for the target protein are bound (non-patent document 23). For example, a BRD4 protein degradation inducing agent newly using E3 ligase DCAF15 has been reported (non-patent document 24). However, it is difficult to say that the BRD4 proteolysis inducing action and cytotoxic action thereof are sufficient. The combination of a ligand for E3 ligase and a binder for the target protein is currently limited (non-patent document 23), and it is desired to find a combination of an appropriate ligand for E3 ligase and a linker structure that is necessary for exhibiting a BRD4 proteolysis inducing action and a cytotoxic action sufficient as an anticancer drug on the binders for BRD4 protein.
