(R)-BEL Usage And Synthesis

Description

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. (R)-Bromoenol lactone ((R)-BEL) is an irreversible, chiral, mechanism-based inhibitor of calcium-independent phospholipase γ (iPLA₂γ). Unlike (S)-BEL, (R)-BEL does not inhibit iPLA₂β except at high doses of 20-30 μM.² (R)-BEL inhibits human recombinant iPLA₂γ with an IC₅₀ of approximately 0.6 μM.
