GtoPdb Ligand ID: 10663

Synonyms: AG-881 | AG881
PDB Ligand
Compound class: Synthetic organic
Comment: Vorasidenib (AG-881) inhibits mutant forms of the isocitrate dehydrogenases (IDH1 and IDH2) [3] that catalyse the generation of the oncogenic metabolite d-2-hydroxyglutarate (2-HG). This compound and others, and their use for treating cancer are claimed in patent US10028961 [4]. Vorasidenib can cross the blood brain barrier, and is being proposed as a chemotherapeutic for IDH mutation +ve cancers including gliomas [2,8] and hematological malignancies [1]. X-ray cocrystal structures of vorasidenib with mutant IDH1 and mutant IDH2 have been deposited with the RCSB Protein Data Bank [3,5]. The X-ray structures show that vorasidenib binds at an allosteric pocket formed in IDH homodimers, at the interface of the two monomers.

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.

Bioactivity Comments
Vorasidenib inhibits IDH1R132H (dimerised with wild type IDH1) with an IC50 of 6 nM, and IDH2R140Q with an IC50 of 12 nM [3]. The IC50s for inhibition of wild type enzymes are not reported. In patients with IDH mutant-carrying gliomas vorasidenib lowers 2-HG levels by >90% [3].
