exchanging the 2-methyl group on the indole ring in the ester and amide series with a hydrogen also generated inactive compounds. Inhibition kinetics revealed that indomethacin amides behave as slow, tight-binding inhibitors of COX-2 and that selectivity is a function of the time-dependent step. Conversion of indomethacin into ester and amide derivatives provides a facile strategy for generating highly selective
我们实验室的最新研究表明,底物类似物抑制剂(例如5,8,11,14-二十碳四丁酸)和非甾体抗炎药(NSAIDs)(例如吲哚美辛和甲氯芬那酸)中羧酸根部分的衍生会导致有效和选择性的环氧合酶-2(COX-2)抑制剂的产生(Kalgutkar等人,Proc.Natl.Acad.Sci.USA 2000,97,925-930)。本文总结了有关结构活性研究的细节,这些研究涉及将芳基丙烯酸NSAID消炎痛转化为COX-2选择性抑制剂。许多结构多样的吲哚美辛酯和酰胺都抑制纯化的人COX-2,其ICo5值在低纳摩尔范围内,但在高达66 microM的浓度下却不抑制绵羊的COX-1活性。吲哚美辛的伯和仲酰胺类似物作为COX-2抑制剂的作用要强于相应的叔酰胺。消炎痛酯或酰胺中的4-氯苯甲酰基被4-溴苄基官能团或氢取代,得到惰性化合物。同样,用氢交换酯和酰胺系列中的吲哚环上的2-甲基也产生了惰性化合物。抑制动力
