C28H35N3O7 (Virginiamycin M1) & C43H49N7O10 (Virginiamycin S1)
525.6 (Virginiamycin M1) & 823.9 (Virginiamycin S1)
Virginiamycin complex is a solid powder mixture of 75% virginiamycin M1 (Ostreogrycin A, sc-202269) and 25% virginiamycin S1(sc-202384), two streptogramin antibiotics which present a synergistic bacteriocidal action. Virginiamycin M1 inhibits the function of the 50S ribosomal subunit without blocking its assembly, producing a bacteriostatic effect. With the addition of the virginiamycin S1 component the complex presents bacteriocidal effects, indicating an interaction between the two compounds upon their association with the ribosome.
An antibiotic used in livestock feed to prevent disease among young swine. Also is used in ethanol production to prevent microbial contamination.
