摘要
A novel class of potent human cytosolic phospholipase A(2) (GIVA PLA(2)) inhibitors was developed. These inhibitors were designed to contain the 2-oxoamide functionality and a free carboxyl group. Among the compounds tested, a long-chain 2-oxoamide containing L-gamma-norleucine was the most potent inhibitor, causing a 50% decrease in GIVA PLA2 activity at 0.009 mole fraction.
