    Antimycin (syn: Antimycin A) is a complex of related macrocyclic lactones, predominantly A1 to A4, isolated from several species of Streptomyces, first reported in the early 1950s for potent antifungal activity. There are over 20 known analogs in the Antimycin A class, mostly involving variation of the fatty acid ester chain length or adjacent alkyl starting unit. Antimycin A is widely used as a bioprobe of respiration and other applications.

    Antimycin A is soluble in ethanol, methanol, DMF and DMSO.

    We also offer:

    • Antimycin A1 (A127)
    • Antimycin A2 (A101)
    • Antimycin A3 (A102)
    • Antimycin A4 (A128)
    Mechanism of Action Antimycin A binds to cytochrome C reductase at the Qi site, inhibiting the oxidation of ubiquinol to ubiquinone.
    Molecular Formula C28H40N2O9 (for A1)
