this work the discovery of the specificity through design, synthesis and structure-activity relationships studies of different kinds of PMS815 derivatives. The leading compound, 4,5-dihydro-3-(4-tetradecyloxybenzyl)-1,2,4-4H-oxadiazol-5-one (9b, PMS1062) exhibits a micromolar IC50 towards three group II PLA2s, while inactive towards four group I and one group III enzymes in two in vitro enzymatic assay
从GI和GII PLA2s的非特异性抑制剂4-十四烷氧基苯甲m(PMS815)开始,我们在这项工作中报告了通过设计,合成和不同种类的PMS815衍生物的结构活性关系研究发现特异性。领先的化合物4,5-二氢-3-(4-十四烷基氧基苄基)-1,2,4-4H-恶二唑-5-酮(9b,PMS1062)对3个II类PLA2表现出微摩尔IC50,对4个PLA2则无活性在两种体外酶分析条件下,第I组和第III组酶。它还能够阻断HepG2细胞系中LPS和IL-6诱导的PLA2-II活性,并且在两种不同的细胞系(A549和LLC-PK1)中测试PMS1062的浓度高达100 microM时,未观察到细胞毒性。 。
