AG Scientific Antimycin A<Sub>3</Sub>, 1 mg

Antimycin A₃ is a homologue of the antimycin complex, first isolated in 1958 from Streptomyces blastimyceticus and coproduced with antimycin A₄. Antimycin A₃ is a more polar analogue of A₁ and A₂. Like all antimycins, antimycin A₃ is a potent inhibitor of respiration by inhibiting the oxidation of ubiquinol to ubiquinone.
 

Antimycin A₃ exhibits broad biological activity as an antifungal, anthelmintic, insecticidal, antiviral and antitumor active. Lack of availability of the individual antimycin components has hindered greater understanding of the common and unique molecular targets of the components of the antimycin complex.
