Bromoenol lactone is a potent and irreversible inhibitor of myocardial cytosolic calcium-independent phospholipase A2 (iPLA2) [1].
The iPLA2 has been involved in stimulus-induced arachidonic acid release and lysophospholipid generation. The catalytic action of iPLA2 is responsible for phospholipid remodeling as a housekeeping function. Arachidonic acid and lysophospholipid generated by iPLA2 act as a signaling molecule in cellular functions, including eicosanoid production, glucose-induced insulin secretion, Fas-induced apoptosis, cellular proliferation, membrane traffic in fusion, contribution to myocardial ischemia, and others [2].
BEL promoted apoptosis in a variety of cell lines, including U937, THP-1, and MonoMac (human phagocyte), RAW264.7 (murine macrophage), Jurkat (human T lymphocyte), and GH3 (human pituitary). Long term treatment with BEL (up to 24 h) increased annexin-V binding to the cell surface and nuclear DNA damage. BEL induced the proteolysis of procaspase-9 and procaspase-3 and increased cleavage of poly (ADP-ribose) polymerase [1]. BEL inhibited cellular phosphatidic acid phosphohydrolase (PAP) activity in intact P388D1 macrophages with an IC50 of ~8 μM. BEL blocked triacylglycerol biosynthesis in P388D1 cells by decreasing diacylglycerol availability [3].
