saturating concentrations of alcohols. Molecular modeling led to the design and synthesis of a series of cyclic, linear, and disubstituted formamides. Evaluation of 23 compounds provided structure-function information and selective inhibitors for the enzymes, which have overlapping but differing substrate specificities. Monosubstituted formamides are good inhibitors of class I and II enzymes, and disubstituted
人醇脱氢酶(HsADH)包含I类(α,β和γ),II类(pi)和IV类(sigma)酶。酶的选择性抑制剂可用于防止形成有毒产物的醇类代谢。甲酰胺是醛的非反应性类似物,并与酶-NADH复合物结合[Ramaswamy,S .; Scholze,M .;Plapp,BV Biochemistry 1997,36,3522-3527]。它们是针对各种浓度酒精的非竞争性抑制剂,即使在饱和浓度的酒精下,它们也有效。分子建模导致了一系列环状,线性和双取代甲酰胺的设计和合成。对23种化合物的评估提供了酶的结构功能信息和选择性抑制剂,这些酶具有重叠但不同的底物特异性。单取代甲酰胺是I和II类酶的良好抑制剂,而双取代甲酰胺对α酶具有选择性。在pH 7和25摄氏度下Ki值为0.33-0.74 microM的选择性抑制剂包括HsADHα的N-环戊基-N-环丁基甲酰胺,HsADH beta1的N-苄基甲酰胺,HsADH
