Abstract

We present the discovery of thieno[3,2-d]pyrimidine SGC-STK17B-1 (11s), a high-quality chemical probe for this understudied “dark” kinase. 11s is an ATP-competitive inhibitor that showed remarkable selectivity over other kinases including the closely related STK17A. X-ray crystallography of 11s and related thieno[3,2-d]pyrimidines bound to STK17B revealed a unique P-loop conformation characterized by a salt bridge between R41 and the carboxylic acid of the inhibitor.
