Technical Field

[0008] The present application relates to the field of drug synthesis, and specifically to a PRMT5 inhibitor and its application. Background Art

[0009] Epigenetic alterations are key mediators driving and maintaining the malignant phenotype of tumors. Changes in DNA methylation, histone acetylation and methylation, noncoding RNAs, and post-translational modifications are all epigenetic drivers of cancer development, independent of DNA sequence changes. Arginine methylation is an important post-translational modification that influences cell growth and proliferation, apoptosis, angiogenesis, and metastasis by regulating transcription and post-transcriptional RNA processing. Three types of methylarginine exist: ω-NG, N'G-asymmetric dimethylarginine (ADMA) and ω-NG, N'G-symmetric dimethylarginine (SDMA). This modification is catalyzed by the protein arginine methyltransferase (PRMT) family, transferring a methyl group from S-adenosylmethionine (AdoMet) to arginine side chains on histones and non-histone proteins. Nine PRMT genes have been annotated in the human genome and are categorized as type I (PRMT1, 2, 3, 4, 6, and 8), type II (PRMT5 and PRMT9), and type III enzymes (PRMT7) based on the type of methylarginine produced. PRMT5 is primarily a type II enzyme that catalyzes the symmetric dimethylation of arginine. PRMT5 was first discovered in a two-hybrid assay to detect proteins that interact with Janus tyrosine kinase (Jak2).

[0010] PRMT5 is a universal transcriptional repressor that forms a complex with other transcription factors, including BRG1 and Hbrm, Blimp1, and Snail. PRMT5 participates in diverse cellular processes by methylating a variety of cytoplasmic and nuclear substrates, including histone H4 residue Arg3 (H4R3) and H3 residue Arg8 (H3R8). H4R3 methylation is associated with transcriptional repression, while H3R8 methylation is considered to be involved in both transcriptional activation and repression. In addition to directly inducing repressive histone marks, PRMT5's role in gene silencing is mediated by the formation of a multi-repressor protein complex, including NuRD components, HDACs, MDB proteins, and DNA methyltransferases. PRMT5 influences its substrate specificity through interactions with several binding proteins. A core component of this protein complex is MEP50, which is essential for the enzymatic activity of PRMT5. Studies have found that PRMT5 can methylate proteins involved in RNA splicing, such as SmD3, which can be used to track the chemical activity of PRMT5 in cell biology.

[0011] PRMT5 plays a crucial role in tumorigenesis. Studies have found that PRMT5 expression is upregulated in a variety of tumors, including lymphoma, lung cancer, breast cancer, and colorectal cancer. Furthermore, PRMT5 expression is elevated in samples from patients with mantle cell lymphoma (MCL), and PRMT5 knockout inhibits MCL cell proliferation, suggesting a key role for PRMT5 in MCL. PRMT5 overexpression promotes cell proliferation, while PRMT5 knockout inhibits cell proliferation in melanoma, breast cancer, and lung cancer cell lines. Therefore, PRMT5 is a potential target for cancer therapy.

[0012] Loss of methylthioadenosine phosphorylase (MTAP) confers a selective reliance on PRMT5 and its binding protein, WDR77. MTAP is frequently lost due to its proximity to the commonly deleted tumor suppressor gene CDKN2A. Cells harboring MTAP deletion have increased levels of intracellular methylthioadenosine (MTA), a metabolite cleaved by MTAP. MTA shares a similar structure to S-adenosylmethionine (SAM). As concentrations increase, MTA acts as an intrinsic, selective inhibitor, inhibiting the binding of SAM to PRMT5 and, consequently, the methyltransferase activity of PRMT5.

[0013] The most significant structural difference between MTAP-deficient and MTAP-wild-type cancer cells lies in the accumulation of MTA in MTAP-deficient cancer cells, which results in the formation of a PRMT5-MTA complex. Inhibitors developed against the PRMT5-MTA complex can selectively target MTAP-deficient cancer cells while minimizing the effect on normal cells, significantly improving the therapeutic index.

[0014] Therefore, identifying and developing small molecules that inhibit PRMT5 activity will be useful as therapeutic approaches for treating various PRMT5-associated diseases or disorders, such as cancer.
