  摘要：

  A study of various 2-[(alkylsulfonyl)oxy]-6-substituted-1H-isoindole-1,3-diones' inhibition of chymotrypsin compared to inhibition of HLE reveals that acylamino substitution in the 6-position increases selectivity and potency of these inhibitors for HLE. The best HLE inhibitor in this series was 6-(methylglutaryl)amino-2-[(ethylsulfonyl)oxy]-1H-isoindole-1,3-dione with a k(obs)/[I] = 220,000 M-1 s(-1). (C) 1999 Elsevier Science Ltd.

  6-acylamino-2-[(ethylsulfonyl)oxy]-1H-isoindole-1,3-diones mechanism-based inhibitors of human leukocyte elastase and cathepsin G: effect of chirality in the 6-acylamino substituent on inhibitory potency and selectivity

  摘要：

  Inhibition of human leukocyte elastase(HLE) by a series of 6-acylamino-2-[(ethylsulfonyl)oxy)]-1H-isoindole-1,3-diones was determined and compared to their inhibition of ChT, PPE, and Cat G. The best inhibitor of the series was 6-((1'S')-camphanyl)amino-2-[(ethylsulfonyl) oxy]-1H-isoindole-1,3-dione 5b, with a k(obs)/[I] = 11,000 M-1 s(-1). this study revealed that HLE shows a preference for the S stereochemistry and tolerates hydrophobic substituents in the S-n(') binding sites. Molecular modeling of non-covalent HLE-inhibitor complexes was used as a tool to investigate our binding model. Buffer stability assays reveal that these compounds are susceptible to hydrolysis at physiological pH. (C) 2001 Elsevier Science Ltd. All rights reserved.
