Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: We obtained the chemical structure for zenuzolac from WHO Proposed list 125 of July 2021, in which it is described as an anti-inflammatory. The INN represents the racemic (rac) mixture of (R) and (S) enantiomers. We show the molecule without specified stereochemistry to represent the mixture. We have mapped this to PubChem CID 10798271. Synonyms from the PubChem entry associate the structure with research code VGX-1027 (VGX Pharmaceuticals). VGX-1027 is an immunomodulatory compound that downregulates proinflammatory cytokine production and NF-κB and MAP kinase activation [1,4-5].

COVID-19: Zenuzolac (re-named as GLS-1027) is being evaluated to determine its potential to reduce SARS-CoV-2-induced pulmonary inflammation (pneumonitis).

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 CDK toolkit. 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.
