Description

Technical Field

[0001] The present invention relates to a compound with SMARCA2 protein degradation function and use thereof in preparing medicines for diseases related to SMARCA2 activity. Background Art

[0002] The mammalian SWI / SNF chromosome remodeling complex drives nucleosome movement by utilizing the energy released by hydrolyzing ATP, thereby participating in key cellular processes such as chromosome structure regulation and DNA repair. Its function is conferred by two mutually exclusive ATP-dependent helicases, SMARCA2 or SMARCA4, whose protein sequences have a high degree of homology. In recent years, SWI / SNF has attracted great attention in cancer biology. Tumor sequencing studies have shown that about 20% of human cancers have mutations in specific core or auxiliary components of the complex. Loss-of-function mutations in the SMARCA4 gene are common in a variety of malignant tumors, including 10-20% of non-small cell lung cancer, 100% of small cell ovarian cancer, 28% of skin cancer, 16% of gliomas, and 14% of colon cancer. In SMARCA4 mutant cancer cells, due to the loss of the SMARCA4 gene, cancer cells will rely on the paralogous SMARCA2 gene for DNA structure regulation and repair. Therefore, selective SMARCA2 inhibitors can induce the death of SMARCA4-deficient cancer cells.

[0003] However, due to the high similarity of SMARCA2 and SMARCA4 protein sequences, small molecule inhibitors targeting this target currently have problems such as poor selectivity, difficulty in drug development, and high toxicity, and cannot be used in clinical practice. Recently, with the vigorous development of PROTAC technology, selective SMARCA2 protein degraders have become a new direction for drug development. Compared with traditional small molecule inhibitors, PROTAC has the opportunity to avoid off-target effects, reduce some serious adverse reactions caused by traditional small molecule inhibitors, and has the potential to solve drug resistance problems.

[0004] Ubiquitin is a small molecule protein that exists in eukaryotic cells and consists of 76 amino acids with a highly conserved sequence. The main function of ubiquitin is to mark target proteins, which can be recognized and degraded by proteasomes. This process is called the ubiquitin / proteasome system. Among them, E3 ubiquitin-protein ligase directly binds to proteins, determining the specificity of degradation. The degradation process of the ubiquitin / proteasome system mainly includes the following four steps: 1) Ubiquitin activation: the carboxyl residue of ubiquitin combines with the thiol group of the ubiquitin activating enzyme E1; 2) Ubiquitin cross-linking: E1 transfers the activated ubiquitin to the ubiquitin-binding enzyme E2 through the transesterification process; 3) E3 binds the ubiquitin complex to the target protein: the ubiquitin-protein ligase E3 connects the ubiquitin bound to E2 to the target protein. If ubiquitin already exists on the target protein, the ubiquitin bound to E2 can be directly connected to the target protein; 4) Proteasome degradation: the proteasome recognizes the marked target protein, thereby hydrolyzing the target protein into a peptide chain of 7-8 amino acids in length, completing the degradation of the target protein.

[0005] The proteolysis targeting chimeric molecule is a bifunctional molecule that can bind to E3 ubiquitin ligase and target protein at the same time, ubiquitinating the target protein that cannot bind to E3 and selectively degrading it through the ubiquitin / proteasome system, thereby controlling the level of target protein in cells. The current E3 ubiquitin ligases mainly include CRBN, VHL, MDM2 and c IAP1, etc. Summary of the invention
