Description

TECHNICAL FIELD

[0001] The present application belongs to the field of drug synthesis, and particularly relates to a tricyclic derivative inhibitor and a preparation method and application thereof. BACKGROUND

[0002] Protein arginine methyltransferases (PRMTs) are divided into three major categories: Type I, II, and III, based on catalytic activity and product type. Type I includes PRMT1 / 2 / 3 / 4 / 6 / 8, which catalyzes the formation of asymmetric dimethylarginine (ADMA) from the substrate; Type II includes PRMT5 / 9, which catalyzes the formation of symmetric dimethylarginine (SDMA) from the substrate; and Type III includes only PRMT7, which is responsible for catalyzing the formation of monomethylarginine (MMA) from the substrate. PRMT5 uses S-adenosyl-L-methionine (SAM) as a methyl donor to transfer a methyl group to DNA, RNA, histone, and other substrates, resulting in the symmetric dimethylation of arginine residues in the substrate to form SDMA, which regulates multiple key cellular processes, including transcription, translation, and DNA repair, to maintain cellular homeostasis. PRMT5 is also involved in regulating tumor cell growth and survival pathways and promotes tumorigenesis and progression. Elevated expression of PRMT5 has been shown to be associated with poor prognosis in various cancers, making it a highly potential epigenetic target.

[0003] Methylthioadenosine phosphorylase (MTAP) catalyzes the formation of methionine from methylthioadenosine (MTA), which is essential for maintaining normal cell function. Deletion mutations in the MTAP gene cause accumulation of MTA in cells, which competes with SAM, the substrate of PRMT5, resulting in decreased PRMT5 activity and the formation of a large amount of PRMT5-MTA complex. Deletion of the MTAP gene increases the dependence of tumors on PRMT5, and inhibition of PRMT5 in MTAP-deficient tumors can have a "synthetic lethal" effect. PARP inhibitors based on the "synthetic lethal" theory have achieved great success in the field of precision therapy in tumors. The MTAP gene is adjacent to the most common tumor suppressor gene CDKN2A in human cancers and is often co-deleted with CDKN2A. This co-deletion accounts for 10-15% of all cancers, mainly in non-small cell lung cancer (12-20%), glioma (53%), pancreatic cancer (30%), and DLBCL (20%), and has a huge market prospect.

[0004] Currently, there is no PRMT5 inhibitor on the market, and early PRMT5 inhibitors are all non-selective substrate SAM competitive inhibitors, with serious blood toxicity and small safety window in clinical practice. The first generation of PRMT5 inhibitors GSK-3326595, JNJ-64619178 and PF-06939999 have poor clinical progress. The new generation of PRMT5 inhibitors targeting PRMT5-MTA complex is only effective for tumors with MTAP deletion and MTA enrichment, has high selectivity for MTAP wild type, reduces blood toxicity from the mechanism, and is verified in preclinical studies, which is expected to greatly improve the safety window.

[0005] The present patent relates to a new PRMT5-MTA selective inhibitor, which is only active for MTAP deletion cells and has weak inhibition for MTAP wild type cells, which can avoid the blood toxicity and other side effects of non-selective PRMT5 inhibitors for MTAP wild type in clinical practice. The highly selective PRMT5-MTA inhibitor can be used as a new PRMT5-MTA inhibitor for the treatment of various tumors, cancers and other diseases. SUMMARY
