Descrição

Descrição geral

Chemical structure: macrolide

Aplicação

The antibiotic virginiamycin is produced by Streptomyces virginiae and is a member of the virginiamycin family. Each member is produced as a mixture of two structurally different compounds that exhibit synergistic antibacterial activity. There are two groups: virginiamycin M1 (VM1) and virginiamycin S (VS). VS is a cyclic hexadepsipeptide. VS and VM1 are both used to inhibit protein synthesis since they are bacteriostatic. When used in combination they are more effective. Virginiamycin is used as a performance promoter in animal husbandry. It is chemically modified to make therapeutic drugs such as quinupristin and dalfopristin[1][2].

Ações bioquímicas/fisiológicas

Cyclic polypeptide antibiotic from Streptomyces sp. Acts as a synergist binding to the conformational change in the peptidyl transferase center fo the 50S ribosome.

Virginiamycin S inhibits bacterial protein synthesis at the level of aminoacyl-tRNA binding and peptide bond formation. It inactivates the 50S ribosome. VS is a cyclic hexadepsipeptide containing a nonproteinogenic amino acid, Lphenylglycine (L-pheGly), in its core structure. The visG gene is required for VS biosynthesis. Nonribosomal peptide synthetase (NRPS) may be involved in VS biosynthesis. Virginiamycin S is active against Gram-positive bacteria[1].

Nota de preparo

Soluble in ethanol, methanol, DMF or DMSO. Limited water solubility.
