A series of compounds derived from 3-alkyl-N-hydroxysuccinimide have been synthesized and their inhibitory activity toward human leukocyte elastase has been investigated. Compounds having an isobutyl or isopropyl group at the C-3 position have been found to be particularly effective inactivators of the enzyme. The introduction of a trans-styryl group (as in compounds 16 and 18) results in a drastic
已经合成了一系列衍生自3-烷基-N-羟基琥珀酰亚胺的化合物,并且已经研究了它们对人白细胞弹性蛋白酶的抑制活性。已经发现在C-3位具有异丁基或异丙基的化合物是该酶特别有效的灭活剂。反式-苯乙烯基的引入(如化合物16和18中的)导致抑制活性的急剧增强,表明苯环和酶的S2'亚位点之间有利的相互作用。发现该化合物在缓冲溶液中高度稳定,在17小时(观察期)后结构完整性没有明显变化。对模型化合物和高场NMR的研究表明,这些化合物可作为酶的基于机理的抑制剂。
