Biochem/physiol Actions

Potent irreversible inhibitor of mitochondrial complex I (NADH:ubiquinone oxidoreductase).

Piericidin A, an antibiotic isolated from Streptomyces mobaraensis, is a potent irreversible inhibitor of mitochondrial complex I (NADH:ubiquinone oxidoreductase). Piericidin A potently binds to ubiquinone binding sites in both mitochondrial and bacterial forms of the enzyme.
