In vitro study | In RBL 2H3 and bone marrow-derived mast cells (BMMCs), Ca 2+ entry is critical for exocytosis. Bromoenol lactone inhibits exocytosis when stimulated using a Ca 2+ ionophore A23187, which passively transports Ca 2+ down a concentration gradient and also in permeabilised mast cells where Ca 2+ entry is no longer relevant. Moreover, Bromoenol lactone has only a minor effect on antigen- or thapsigargin-stimulated Ca 2+ signalling, both the release from internal stores and sustained elevation due to Ca 2+ influx. |
Hazard Symbols | Xi - Irritant |
Risk Codes | 36/37/38 - Irritating to eyes, respiratory system and skin. |
Safety Description | 26 - In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. |

Biological activity | Bromoenol lactone ((6E)-Bromoenol lactone) is an irreversible selective and effective calcium-dependent phospholipase A2 (iPLA2β) inhibitor, its IC50 value is about 7 μM, which can inhibit antigen-stimulated mast cell exocytosis without preventing the influx of Ca2 +. |
target | PLA2 7 μM (IC 50 ) |
