(R) -Bromoenol lactone (5 mg/ml solution in methyl acetate)

(R) -Bromoenol lactone is a potent and selective mechanism-based inhibitor of calcium-independent phospholipase A2γ (iPLA2γ), with an IC50 of ~0.6 μM, showing minimal activity against iPLA2β. This chiral compound is a valuable research tool for studying roles of iPLA2γ in lipid signaling, membrane dynamics, and associated in vitro and in vivo disease models.
