H+ ATPase inhibitor
Antibiotic. More potent and specific H+-ATPase inhibitor than bafilomycin A1 (Prod. No. BML-CM110). Inhibits acidification of organelles such as lysosomes and the Golgi apparatus. Blocks cell surface expression of viral glycoproteins without affecting their synthesis. Exhibits cytotoxic effects in a number of cell lines in a cell viability assay. Induces nitric oxide (NO) production. Inhibits Autophagy.
