Applications

As other Aurovertin group members, Citreoviridin binds to and inhibit mitochondrial ATPase, thereby uncoupling oxidative phosphorylation.

Citreoviridin, a mycotoxin that has been shown to inhibit the mitochondrial ATP synthetase system. It inhibits soluble ATPase, ADP-stimulated respiration in isolated rat liver mitochondria, and ATP-driven reduction of NAD+ by succinate (KD = 2 µM). Citreoviridin has been used to target ectopic ATPase activity in cancer cells in order to modulate the metabolic activity associated with tumorigenesis.

Applications

Cerulenin was originally proposed as antifungal antibiotic. Cerulenin is used as a biochemical tool. Cerulenin has been shown to cause dramatic weight loss in animals. Cerulenin blocks synthesis of fatty acids and sterols by binding to the enzyme fatty-acid-synthase. In some tumor lines, this triggers apoptosis., an effect believed to be mediated by the accumulation of malonyl-coenzyme A in cells with an upregulated FAS pathway.

Applications

Bafilomycin A1 is a specific inhibitor of vacuolar type H+-ATPase (V-ATPase) in animal cells, plant cells and microorganisms. Bafilomycin A1 is useful in distinguishing among different types of ATPases. Bafilomycin A1 can prevent the re-acidification of synaptic vesicles once they have undergone exocytosis. Antibacterial, Antifungal, Antineoplastic, Immunosuppressive Bafilomycin A1 has been shown to decrease multi-drug resistance.

Bafilomycin A1, inhibits vacuolar-​ATPase.
It is a potassium ionophore that impairs mitochondrial functions.
It activates respiration of neuronal cells via uncoupling associated with flickering depolarization of mitochondria.
Bafilomycin A1 has been commonly used as a method of inhibition of infection by viruses known or suspected to follow the path of receptor-​mediated endocytosis and low-​pH-​mediated membrane fusion
Vacuolar ATPase inhibitors overcome Bcl-​xL-​mediated chemoresistance through restoration of a caspase-​independent apoptotic pathway.
