The phospholipases are an extensive family of lipid hydrolases that function in cell signaling, digestion, membrane remodeling, and as venom components.1 The calcium-independent phospholipases (iPLA2) are a PLA2 subfamily closely associated with the release of arachidonic acid in response to physiologic stimuli. (S)-Bromoenol lactone ((S)-BEL) is an irreversible, chiral, mechanism-based inhibitor of calcium-independent phospholipase β (iPLA2β) that inhibits the vasopressin-induced release of arachidonate from cultured rat aortic smooth muscle (A10) cells with an IC50 value of 2 µM.2 (S)-BEL is more than 1,000-fold selective for iPLA2 versus cPLA2, and is 10-fold selective for iPLA2β versus iPLA2γ.
