GtoPdb Ligand ID: 13755

Synonyms: staphylomycin S | virgimycin
Compound class: Natural product
Comment: Virginiamycin S1 is a streptogramin antibacterial produced by a Streptomyces sp. related to S. virginiae [5]. It is isolated as part of a virginiamycin complex containing M components (M1 and M2) and S components (S1-S4)(reviewed in [1]). Virginiamycin S1 and pristinamycin IIA (virginiamycin M1) are the major components of virginiamycin [2], an antibacterial used in veterinary medicine and also in animal husbandry as a growth promoter.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Summary of Clinical Use Click here for help
Virginiamycin is approved by the US FDA for use in animal production as a growth promoter and in veterinary medicine. It is administered as a medicated feed and indicated for the control and treatment of swine dysentery and for the prevention of necrotic enteritis caused by Clostridium perfringens in poultry. Virginiamycin was used as a growth promoter in the European Union, but authorisation was withdrawn in 1998.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Both components of virginiamycin bind to the 50S subunit of the bacterial ribosome, acting synergistically to inhibit protein synthesis [3].
