Crystal Structure of Human Chymase with Benzimidazolone Inhibitor
Structural highlights
FunctionCMA1_HUMAN Major secreted protease of mast cells with suspected roles in vasoactive peptide generation, extracellular matrix degradation, and regulation of gland secretion. Publication Abstract from PubMedA new class of chymase inhibitor featuring a benzimidazolone core with an acid side chain and a P(1) hydrophobic moiety is described. Incubation of the lead compound with GSH resulted in the formation of a GSH conjugate on the benzothiophene P(1) moiety. Replacement of the benzothiophene with different heterocyclic systems such as indoles and benzoisothiazole is feasible. Among the P(1) replacements, benzoisothiazole prevents the formation of GSH conjugate and an in silico analysis of oxidative potentials agreed with the experimental outcome.
