Benzimidazolone as potent chymase inhibitor: Modulation of reactive metabolite formation in the hydrophobic (P1) region
摘要:
A 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. (C) 2011 Elsevier Ltd.
