Description | 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]. |

In Vitro | In RBL 2H3 and bone marrow-derived mast cells (BMMCs), Ca2+ entry is critical for exocytosis. Bromoenol lactone inhibits exocytosis when stimulated using a Ca2+ ionophore A23187, which passively transports Ca2+ down a concentration gradient and also in permeabilised mast cells where Ca2+ entry is no longer relevant. Moreover, Bromoenol lactone has only a minor effect on antigen- or thapsigargin-stimulated Ca2+ signalling, both the release from internal stores and sustained elevation due to Ca2+ influx[1]. |
