GtoPdb Ligand ID: 13548

Synonyms: compound 19c [PMID: 32666789]
Compound class: Synthetic organic
Comment: OTB-658 is a prelinical candidate belonging to the oxazolidinone class of antibacterial compounds. It was discovered using a structure-activity aided strategy to identify novel oxazolidinones that retain activity against Mycobacterium tuberculosis but have reduced toxicity [4].

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
It has been reported that OTB-658 was approved for clinical trials by the Chinese National Medical Products Administration in 2020, and that a Phase 1 clinical trial has begun [3]. However, we have been unable to find the registration for this clinical trial.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
The antibacterial MMOA of oxazolidinones is inhibition of protein synthesis by blocking function of the bacterial 50S ribosomal subunit [2].
