The inhibitory activity of a series of aryl azolides and sulfonate salts toward human leukocyte elastase is reported. Several of the compounds were found to be potent inhibitors of the enzyme. Active compounds were obtained only when the specificity group and the reactive moiety were separated by a two-carbon chain. The introduction of hydrophobic groups enhanced the inhibitory activity of these compounds
报道了一系列的芳基偶氮化物和磺酸盐对人白细胞弹性蛋白酶的抑制活性。发现几种化合物是该酶的有效抑制剂。仅当特异性基团和反应性部分被两条碳链隔开时,才获得活性化合物。除磺酸盐以外,疏水基团的引入增强了这些化合物的抑制活性。离去基团的性质对抑制活性有深远的影响,化合物23和26的活性最高(分别为kobsd / [I] = 11,722和13,500 M-1 s-1)。
