Synonyms: RTA 408 | RTA-408 | Skyclarys®
Approved drug Immunopharmacology Ligand
omaveloxolone is an approved drug (FDA (2023), EMA (2024))
Compound class: Synthetic organic
Comment: Chemically omaveloxolone (RTA 408) is a second generation synthetic oleanane triterpenoid compound, which structurally resembles bardoxolone, and has difluoropropanamide replacing the carboxylic acid moiety.
This compound is claimed in patent WO2013163344A1. The chemical structure represented above, was drawn from this patent, but structures with alternate stereochemistry are submitted in PubChem.
Pharmacologically omaveloxolone activates the Nrf2 transcription factor, to modulate expression of proteins that have antioxidative, anti-inflammatory, and mitochondrial bioenergetic activities [6-7].

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.
