Abstract

Inhibition of methionine adenosyltransferase 2A (MAT2A) has received significant interest because of its implication as a synthetic lethal target in methylthioadenosine phosphorylase (MTAP)-deleted cancers. Here, we report the discovery of a series of 3H-pyrido[1,2-c]pyrimidin-3-one derivatives as novel MAT2A inhibitors. The selected compound 30 exhibited high potency for MAT2A inhibition and a favorable pharmacokinetic profile. Furthermore, in an HCT-116 MTAP-deleted xenograft model, compound 30 showed better in vivo potency than current clinical compound AG-270.
