Abstract

BMX is a member of TEC family nonreceptor tyrosine kinase and is involved in a variety of critical physiological and pathological processes. Through combination of irreversible inhibitor design and type II inhibitor design approaches, we have discovered a highly selective and potent type II irreversible BMX Kinase Inhibitor compound 41 (CHMFL-BMX-078), which exhibited an IC50 of 11 nM by formation of a covalent bond with cysteine 496 residue in the DFG-out inactive conformation of BMX. It displayed a high selectivity profile (S score(1) = 0.01) against the 468 kinases/mutants in the KINOMEscan evaluation and achieved at least 40-fold selectivity over Btk kinase. Given the fact that BMX mediated signaling pathway is still not fully understood, compound 41 would serve as a useful pharmacological tool to elucidate the detailed mechanism of BMX mediated signaling pathways.
