Bromoenol lactone

Bromoenol lactone ((6E) -Bromoenol lactone) is a suicide-based irreversible, selective, potent inhibitor of calcium-independent phospholipase A2 (iPLA2β) with an IC50 value of approximately 7 μM, which inhibits antigen-stimulated mast cell exocytosis without blocking Ca2+ influx[1][2].
