relationship studies, we investigated the effect of the substitution of the electrophilic ketone group in the middle part of the molecule by other polar residues, such as hydroxyimino, azido, acyloxy, acylamino, urea and carbamate, on enzyme inhibition. With an IC50 of 1.7 μM against cPLA2α from human platelets, the 4-fluorophenylcarbamate derivative 23f was the most active of the compounds tested.
吲哚-5-羧酸与在位置1 3-芳氧基-2-氧代丙基残基已被发现是人类的有效抑制剂胞浆型磷脂酶甲2 α(与cPLA 2 α)。在结构-活性关系研究过程中,我们研究了分子中部的亲电子酮基团被其他极性残基(例如羟基亚氨基,叠氮基,酰氧基,酰氨基,尿素和氨基甲酸酯)取代对酶抑制的影响。与IC 50针对与cPLA 1.7μM 2从人血小板α,4-氟苯衍生物23F是最活跃的测试化合物。
