VIRGINIAMYCIN M1 Chemical Properties,Usage,Production
Chemical Properties
Light yellow powder
Uses
Macrolactone antibiotic. Antibacterial; growth promotant.
Uses
Ostreogrycin A (virginiamycin M1, streptogramin A) is the major component of the virginamycin complex. In the 1950s this complex was independently discovered so many times that the literature became highly confusing. Ostreogrycin A is a macrocyclic lactone antibiotic that acts synergistically with the structurally unrelated cyclic depsipeptides, virginiamycin B (ostreogrycin B, streptogramin B) and virginiamycin S, to inhibit peptide elongation. This is achieved by blocking formation of a peptide bond between the growing peptide chain (peptidyl-tRNA) linked to the 50S ribosome and aminoacyl-tRNA. Ostreogrycin A is highly active against Gram positive bacteria, particularly MRSA.

Definition
ChEBI: A macrolide that is (together with pristinamycin IA) a component of pristinamycin, an oral streptogramin antibiotic produced by Streptomyces pristinaespiralis. Pristinamycin exhibits bactericidal activity against Gram positive organisms includ ng methicillin-resistant Staphylococcus aureus.
Biological Activity
virginiamycin m1 is a macrolide antibiotic that reversibly inhibits protein synthesis [1][2][3].virginiamycin complex contains two antibiotics, virginiamycin m1 and virginiamycin s1. streptogramins are divided into class a and class b based on their structures. virginiamycin m1, also known as streptogramin a, is a member of the streptogramin a group of antibiotics, which bind the 50s ribosomal subunit at the peptidyl transferase center to inhibit initiation and translocation. they show good bactericidal activity against methicillin-resistant s. aureus (mrsa), although resistance in mrsa is conferred by the cfr gene. virginiamycin m1 has activity against gram-positive and in select cases gram-negative bacteria. combination of group a and b streptogramins exhibit bactericidal activity [1]. virginiamycin m1 acted synergistically with virginiamycin s1 to irreversibly inhibit protein synthesis in bacteria. in cell-free systems, virginiamycin m1 and virginiamycin s1 bound to the large ribosomal subunit, and the affinity of ribosomes for vs is increased by vm [2][3].
Contact allergens
Pristinamycin is a systemic antibiotic of the synergistins/ streptogramins class, composed of two subunits: pristinamycin IA and pristinamycin IIA. It induces several types of drug reactions such as maculo-papular exanthema, systemic dermatitis, or acute generalized exanthematous pustulosis. Some patients have been previously skin-sensitized by virginiamycin. Crossreactivity is expected to virginiamycin and to the associated dalfopristin and quinupristin.
Contact allergens
Like the other streptogramin, pristinamycin, virginiamycin is made of two subunits, virginiamycin S1 and virginiamycin M1. Dermatitis was quite common in people using the formerly available topical virginiamycin. Occupational dermatitis was observed in the pharmaceutical industry, in breeders, and in a surgeon who used topical virginiamycin on postoperative wounds (personal observation).
