体外研究
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.
