    Piericidin A

    $191.50 - $663.50
    Piericidin A is the major analogue of a family of pyridyl antibiotics isolated from selected Streptomyces species.

    Piericidin A is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.
    Mechanism of ActionPiericidin A is a specific, potent inhibitor of NADH-ubiquinone oxidoreductase (Complex I) that binds to ubiquinone binding site(s). Piericidin A inhibits both mitochondrial and bacterial NADH-ubiquinone oxidoreductases, binding close to NUOD-NUOB interface.
