Group VIA calcium-independent phospholipase A2 (GVIA iPLA2) has recently emerged as a novel pharmaceutical target. We have now explored the structure−activity relationship between fluoroketones and GVIA iPLA2 inhibition. The presence of a naphthyl group proved to be of paramount importance. 1,1,1-Trifluoro-6-(naphthalen-2-yl)hexan-2-one (FKGK18) is the most potent inhibitor of GVIA iPLA2 (XI(50) =
VIA 组钙非依赖性磷脂酶 A 2 (GVIA iPLA 2 ) 最近已成为一种新的药物靶点。我们现在已经探索了氟酮和 GVIA iPLA 2抑制之间的构效关系。萘基的存在被证明是极其重要的。1,1,1-Trifluoro-6-(naphthalen-2-yl)hexan-2-one (FKGK18) 是迄今为止报道的最有效的 GVIA iPLA 2抑制剂( X I (50) = 0.0002)。GVIA iPLA 2的效力分别是 GIVA cPLA 2和 GV sPLA 2 的195 倍和 >455 倍,使其成为探索 GVIA iPLA 2作用的宝贵工具在细胞和体内模型中。1,1,1,2,2,3,3-Heptafluoro-8-(naphthalene-2-yl)octan-4-one 抑制 GVIA iPLA 2,X I (50) 值为 0.001,同时抑制其他细胞内 GIVA cPLA
