GtoPdb Ligand ID: 10795

Synonyms: MRX-1 | MRX-I | Youxitai®
Approved drug PDB Ligand
contezolid is an approved drug (China (2021))
Compound class: Synthetic organic
Comment: Contezolid is an oxazolidinone antibacterial against Gram-positive pathogens [1], including methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae, penicillin-intermediate S. pneumoniae (PISP), and vancomycin-resistant enterococci (VRE). Its orally delivered prodrug is contezolid acefosamil (parent) (MRX-4). Contezolid targets protein synthesis by binding to the V region of the bacterial 23S rRNA.

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.

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.
