Description | Bromoenol lactone is a suicide-based irreversible, selective, potent inhibitor of calcium-independent phospholipase A2 (iPLA2β; IC50: ~7 μM). It inhibits antigen-stimulated mast cell exocytosis without blocking Ca2+ influx. |
In vitro | Bromoenol lactone inhibits exocytosis when stimulated using a Ca2+ ionophore A23187, which passively transports Ca2+ down a concentration gradient and also in permeabilized mast cells where Ca2+ entry is no longer relevant. In RBL 2H3 and bone marrow-derived mast cells (BMMCs), Ca2+ entry is critical for exocytosis. Moreover, Bromoenol lactone has only a minor effect on antigen- or thapsigargin-stimulated Ca2+ signaling, both the release from internal stores and sustained elevation due to Ca2+ influx [1]. |
