4-[（1-氧代-7-苯基庚基）氨基]-（4R）-辛酸是一种基于（R）-α-正亮氨酸的简单酰胺，是sPLA2的选择性抑制剂。它对0.091摩尔分数的sPLA2表现出95％的抑制作用（XI（50）= 0.003），而不会影响cPLA2或iPLA2的活性。 4-[(1-oxo-7-phenylheptyl)amino]-(4R)-octanoic acid a simple amide based on (R)-α-norleucine, is a selective and potent inhibitor of sPLA2. It exhibits 95% inhibition (XI(50) = 0.003) of sPLA2 at 0.091 mole fraction without affecting the activities of cPLA2 or iPLA2.
