Virginiamycin M1 (Pristinamycin IIA; Ostreogrycin A), produced by Streptomyces virginiae, is an polyunsaturated macrocyclic lactone antibiotic and acts as a component of Virginiamycin (HY-112665)[1]. Virginiamycin M1 alone is against Staphylococcus aureus with a MIC of 0.25 μg/mL. IC50 & Target:Bacterial[1] In Vitro:Virginiamycin is an animal-specific antibiotic containing a lactone ring. Virginiamycin is not a single molecule but contains 70-80% of the M1 component (M1 factor) and 20-30% of the S1 component (S1 factor). Virginiamycin M1 is a macrolide and Virginiamycin S1 is a cyclic polypeptide. The minimum inhibitory concentration (MIC) of the individual Virginiamycin M1 component against Staphylococcus aureus is 0.25 μg/mL, and the Virginiamycin S1 component is 4 μg/mL, whereas the combination of the two is 0.125 μg/mL, which improves the bactericidal effect 1~30 times[2].
