Symmetrical anhydride-type serine protease inhibitors: Structure-activity relationship studies of human chymase inhibitors
摘要:
We prepared a potent and relatively selective human chymase inhibitor 9 (-), based on the study of SAR of a symmetrical anhydride-type serine protease inhibitor 1. Kinetic studies suggested that 9 (-) reacts with the Ser residue at the active site of the enzyme, forming a stable acyl enzyme complex. We also showed the importance of the tri-substituted beta-amino acid structure for the potent anti-enzymatic activity, (C) 1999 Elsevier Science Ltd. All rights reserved.

We introduce a new potent inhibitor, N-[2, 2-dimethyl-3-(N-(4-cyanobenzoyl)amino)nonanoyl]-L-phenylalanine ethylester (3), which preferentially inhibits serine proteases belonging to a chymotrypsin superfamily. This inhibitor, despite consisting of a stable ethylester structure, showed strong inhibitory activities toward bovine alpha-chymotrypsin, human cathepsin G, and porcine elastase by acting
