  Orally active .beta.-lactam inhibitors of human leukocyte elastase-1. Activity of 3,3-diethyl-2-azetidinones

  摘要：

  A thorough analysis of the mechanism of inhibition of human leukocyte elastase (HLE) by a monocyclic beta-lactam and the mechanism of beta-lactam hydrolysis led to the preparation of potent and highly stable inhibitors of HLE. This work led to the identification of 4-[(4-carboxyphenyl)-oxy]-3,3-diethyl-1-[[(phenylmethyl)amino]carbonyl]-2-azetidinone (2) as the first orally active inhibitor of human leukocyte elastase (HLE). Analogs of 2 with different substituents on the urea N were synthesized and evaluated for their activity in vitro against HLE as well as in vivo in a hamster lung hemorrhage model. Compounds with a methyl or a methoxy group in the para position of the benzene ring were very potent in both assays. The results are discussed on the basis of the proposed model for the binding of this class of inhibitors to HLE and a possible mechanism of inhibition is presented.

  摘要：

  通过使用LArSR方程研究了2-芳基-1-氰基-1-(三氟甲基)乙基三氟甲烷磺酸酯（α-OTf）和2-芳基-2-氰基-2-(三氟甲基)乙基三氟甲烷磺酸酯（β-OTf）的醋酸解离速率的取代基效应。得到的ρ值和r+值分别为α-OTf的ρ = −3.28，r+ = 0.98，以及β-OTf的ρ = −3.48，r+ = 0.93。获得的ρ值与典型的芳基辅助的溶剂解离相当，但r+值要大得多。较大的r+值表明，在去活化的芳基辅助溶剂解离中，酯键的断裂得到了β-芳基团的强力参与的帮助。
