General description
Chemical structure: peptide
Antimycin is an antibiotic produced by Streptomyces species. It inhibits mitochondrial electron transport chain complex III and favors reactive oxygen species (ROS) production, impairing mitochondrial depolarization. It inhibits nitric oxide-mediated apoptosis and modulatescytochrome C release. It suppresses tumorigenesis in lung cancer cells and could be a potential therapeutic agent.Antimycin A serves as a positive control for superoxide generation.
Application
Antimycin A has been used to study the specific sites of reactive oxygen species production in mitochondria isolated from skeletal muscle of chronic obstructive pulmonary disease patients, and its relationship with local oxidative stress induced by exercise
Antimycin A from Streptomyces sp. has been used:
- as a respiratory chain inhibitor in neuronal cultures[1]
- in organello ATP production assay in Trypanosoma brucei cells
- in respiration assay for papillary thyroid carcinoma (PTC) cell lines
Biochem/physiol Actions
Inhibitor of electron transfer at complex III. Induces apoptosis.
Analysis Note
A mixture of antimycins.

How long we can keep antimycin a solution in dmso and at what temperature its storage is preferable.
1 answer-
This product is tested for solubility in ethanol at 50 mg/mL. Stock solutions prepared in ethanol are stable when stored in aliquots at –20 °C. The solution stability in DMSO has not been determined but is expected to be comparable to ethanol. While a time frame has not been established, stock solutions are quite stable. A general range of 1-3 months is suggested.
