Virginiamycin
Virginiamycin complex contains two streptogramin antibiotics, virginiamycin M1 (75%) and virginiamycin S1 (25%). It is an antibiotic used primarily in the treatment of staphylococcal infections, and to a less extent streptococcal infections. Uses: Anti-bacterial agents. Synonyms: Pristinamycin. CAS No. 11006-76-1. Molecular formula: C71H84N10O17. Mole weight: 1349.48.
Virginiamycin B
Virginiamycin B is a depsipeptide antibiotic co-produced with ostreogrycin A and used as a synergistic mixture. Virginiamycin B, also known as ostreogrycin B and streptogramin B among other synonyms, was discovered independently and named by several groups leading to considerable confusion in the literature. Viriginiamycin B acts as a synergist binding to the conformational change in the peptidyl transferase centre of the 50S ribosome induced by ostreogrycin A. Group: Biochemicals.

Virginiamycin Complex
Virginiamycin complex is defined as a mixture of 75% virginamycin M1 (ostreogrycin A) and 25% virginiamycin S1 and the less abundant S analogs. As the two major components have quite different solubilities these proportions are not readily achieved or used. The individual components are isolated and re-combined to provide the defined components of virginiamycin complex. The structure composition of the complex is important as Virginiamycin S1 acts a synergist, binding to the conformational change of the peptidyl transferase center of the 50S ribosome induced by ostreogrycin A.
