Substrate activity screening was used to rapidly identify a novel and potent ( k inact / K i =59 000 M −1 s −1 ) nonpeptidic chymotrypsin inhibitor with M W <500. The inhibitor is more potent than the best reported tetrapeptidyl phosphonate chymotrypsin inhibitor and demonstrated selectivity over a panel of other serine proteases, including the closely related enzyme cathepsin G.
