Antibiotics are antimicrobial compounds used in the treatment and prevention of bacterial infection. They can either kill or they can inhibit the growth of bacteria. Several antibiotics are also effective against fungi and protozoans. Some are toxic to humans and animals, even when given in therapeutic dosages. Antibacterial antibiotics are commonly classified based on their mechanism of action, chemical structure, or spectrum of activity. Most antibiotics target bacterial metabolic functions or growth processes. Those antibiotics that interfere with the function of essential bacterial enzymes, or that target the bacterial cell wall or the cell membrane, are usually bactericidal. Those that target protein synthesis are usually bacteriostatic. Further categorizations can be made based on target specificity. Use of antibiotics is essential in retaining the purity of particular selection factors in populations of cells. In recent years antibiotics have been found to be valuable in a wide range of life science disciplines. Fermentek has had particular success in manufacturing antibiotics using fermentation processes.

Description

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 analogues in the antimycin A class, mostly involving variation of the fatty acid ester chain length or adjacent alkyl starting unit. Antimycin A binds to cytochrome C reductase at the Qi site, inhibiting the oxidation of ubiquinol to ubiquinone. Antimycin A is widely used as a bioprobe of respiration and other applications with over 5,000 literature citations.

Some of data brought in this page, such as Molecular Weight, relates to Antimycin A1
