Design, Synthesis, and Pharmacological Evaluation of Multisubstituted Pyrido[4,3-d]pyrimidine Analogues Bearing Deuterated Methylene Linkers as Potent KRASG12D Inhibitors.

Abstract excerpt

The breakthrough in drug development of KRASG12C inhibitors provides inspiration for targeting alternative KRAS mutations, especially the most prevalent KRASG12D variant. Based on the structural analysis of MRTX1133 in complex with KRASG12D, a comprehensive structure-activity study was conducted, which led to the discovery of several compounds (22, 28, and 31) that showed higher potency in suppressing the...
