Design and synthesis of Thiadiazoles and Thiazoles targeting the Bcr-Abl T315I mutant: from docking false positives to ATP-noncompetitive inhibitors

Abstract

Overcoming resistance: In an effort to optimize our previously identified dual Src/Abl hits, a new series of 1,3,4-thiadiazoles and 1,3-thiazoles were designed and synthesized, paying particular attention to the reduction of their lipophilicity and to the improvement of the affinity towards the drug-resistant T315I mutant. Compound 5 was identified as a promising allosteric inhibitor of the T315I mutant
