of synthetic compounds (bromoenol lactone and polyfluoroketones). To expand the chemical diversity, a variety of 2-oxoamides based on dipeptides and ether dipeptides were synthesized and studied for their in vitro inhibitory activity on human GVIA iPLA2 and their selectivity over the other major intracellular GIVA cPLA2 and the secreted GV sPLA2. Structure-activity relationship studies revealed the
不依赖钙的磷脂酶A 2(GVIA iPLA 2)最近引起了人们的关注,将其作为药物靶标。已知的GVIA iPLA 2抑制剂的数量仅限于少数几种合成化合物(溴烯醇内酯和多氟酮)。为了扩大化学多样性,合成了多种基于二肽和醚二肽的2-氧酰胺,并研究了它们对人GVIA iPLA 2的体外抑制活性以及对其他主要细胞内GIVA cPLA 2和分泌的GV sPLA 2的选择性。。结构-活性关系研究表明,第一个2-氧代酰胺衍生物(GK317)对GVIA iPLA 2(X I(50)值为0.007),同时相对于GIVA cPLA 2和GV sPLA 2具有显着的选择性。
