What is Virginiamycin?

Plain description, key identifiers and synonyms

Virginiamycin is a class of streptogramin-related depsipeptides isolated from the bacterium Streptomyces virginiae and other Streptomyces bacterial species. The virginiamycins consist of two major components, virginiamycin M1 and virginiamycin S1. These agents bind to and inhibit ribosome assembly, thereby preventing protein synthesis. Active against Gram-positive bacteria, these antibiotics are primarily used in veterinary practice. (NCI04)

How it is made

Virginiamycin is an antibiotic complex produced by a Streptomyces related to S. virginiae. It is a mixture of two principal components designated virginiamycin M1 (21411-53-0) and virginiamycin S1 (23152-29-6).

Antibiotics are fermentation products and are isolated either as unfinished products or as intermediates, generally solid substances of limited stability. They are purified by methods normally employed in organic chemistry, which include chromatography, crystallization, and precipitation. (Antibiotics)
