Краткое описание
N-Acyl-beta-sultams are time dependent irreversible active site directed inhibitors of elastase. The rate of inactivation is first order with respect to beta-sultam concentration and the second order rate constants show a similar dependence on pH to that for the hydrolysis of a peptide substrate. Inactivation is due to the formation of a stable 1:1 enzyme inhibitor complex as a result of the active site serine being sulfonylated by the beta-sultam. Ring opening of the beta-sultam occurs by S-N fission in contrast to the C-N fission observed in the acylation of elastase by N-acylsulfonamides. Structure-activity effects are compared between sulfonylation of the enzyme and alkaline hydrolysis. Variation in 4-alkyl and N-substituted beta-sultams causes differences in the rates of inactivation by 4 orders of magnitude.
