were designed to inactivate human leukocyte elastase (HLE) in three steps: first acylation of active-site serine; second, creation of a powerful new electrophilic center; third, covalent capture of a nucleophile from the enzyme. Both types do irreversibly inactivate HLE, and structure-activity relationships are in accord with the proposed mechanism. In each series, one molecule of the most active compound
合成了两种类型的单环氮杂环丁酮,它们设计成通过三个步骤使人白细胞弹性蛋白酶(HLE)失活。第二,建立一个强大的新的亲电子中心;第三,从酶中共价捕获亲核试剂。两种类型均不可逆地使HLE失活,并且结构-活性关系与所提出的机制一致。在每个系列中,每20次遭遇中至少有1次分子中活性最高的化合物会抑制1个分子的HLE。
