Abstract

The gene encoding for MTAP is one of the most commonly deleted genes in cancer, occurring in approximately 10–15% of all human cancer. We have previously described the discovery of TNG908, a brain-penetrant clinical-stage compound that selectively targets MTAP-deleted cancer cells by binding to and inhibiting PRMT5 cooperatively with MTA, which is present in elevated concentrations in MTAP-deleted cells. Herein we describe the discovery of TNG462, a more potent and selective MTA-cooperative PRMT5 inhibitor with improved DMPK properties that is selective for MTAP-deleted cancers and is currently in Phase I/II clinical trials.

MTAP编码基因是癌症中最常见的缺失基因之一,约占人类癌症总数的10%-15%。我们以前曾介绍过 TNG908 的发现,这是一种具有脑穿透力的临床阶段化合物,通过与 MTAP 缺失细胞中浓度升高的 MTA 结合并协同抑制 PRMT5,从而选择性地靶向 MTAP 缺失的癌细胞。在此,我们介绍了 TNG462 的发现,它是一种更有效、更具选择性的 MTA 协同 PRMT5 抑制剂,具有更好的 DMPK 特性,可选择性地抑制 MTAP 缺失型癌症,目前正处于 I/II 期临床试验阶段。

期刊介绍: The Journal of Medicinal Chemistry is a prestigious biweekly peer-reviewed publication that focuses on the multifaceted field of medicinal chemistry. Since its inception in 1959 as the Journal of Medicinal and Pharmaceutical Chemistry, it has evolved to become a cornerstone in the dissemination of research findings related to the design, synthesis, and development of therapeutic agents. The Journal of Medicinal Chemistry is recognized for its significant impact in the scientific community, as evidenced by its 2022 impact factor of 7.3. This metric reflects the journal's influence and the importance of its content in shaping the future of drug discovery and development. The journal serves as a vital resource for chemists, pharmacologists, and other researchers interested in the molecular mechanisms of drug action and the optimization of therapeutic compounds.
