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.
