Identification of 6-substituted 4-arylsulfonyl-1,4-diazepane-2,5-diones as a novel scaffold for human chymase inhibitors

A novel series of 6-substituted 4-sulfonyl-1,4-diazepane-2,5-diones were designed, synthesized and evaluated as human chymase inhibitors. Structure–activity relationship studies led to the identification of a potent inhibitor, (6S)-6-(5-chloro-2-methoxybenzyl)-4-[(4-chlorophenyl)sulfonyl]-1,4-diazepane-2,5-dione, with an IC50 of 0.027 μM.
