Description: Bafilomycin A1, also known as NSC 381866, is a selective, reversible inhibitor of vacuolar H+-ATPases (V-ATPases), blocking these proton pumps in mammalian, plant, or fungal cells with an IC50 value in the 4-400 nM range. Bafilomycin A1 triggers proliferative potential of senescent cancer cells in vitro and in NOD/SCID mice. Bafilomycin A1 induces caspase-independent cell death in hepatocellular carcinoma cells via targeting of autophagy and MAPK pathways.
