Abstact

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.
