    摘要： The disclosure provides a series of 2-oxoamides based on dipeptides and pseudodipeptides, which were synthesized and their activities toward two human intracellular phospholipases A2 (GIVA CPLA 2 and GVIA 1PLA 2) and one human secretory phospholipase A2 (GV sPLA 2) were evaluated. Derivatives containing a free carboxyl group are selective GIVA cPLA 2 inhibitors. A derivative based on the ethyl ester of an ether pseudodipeptide is the first 2-oxoamide, which preferentially inhibits GVIA iPLA 2. The effect of 2-oxoamides on the generation of arachidonic acid from RAW 264.7 macrophages was also studied. It was found that selective GIVA cPLA 2 inhibitors preferentially inhibited cellular arachidonic acid release; in which one pseudodipeptide gave an IC50 value of 2 μM.
