GtoPdb Ligand ID: 9722

Synonyms: Arakoda® | etaquine | Krintafel® | WR238605
Approved drug Antimalarial Ligand
tafenoquine is an approved drug (FDA (2018))
Compound class: Synthetic organic
Comment: Tafenoquine is an 8-aminoquinoline derivative that has potent antimalarial activity and is a synthetic analogue of primaquine.
The INN record for tafenoquine indicates that it is a racemic mixture. We show the chemical structure without stereochemistry to represent the mixture. The non-isomeric structure is also represented in the PubChem and ChEMBL entries listed in the links table below, while the two enantiomers forming the racemate are represented by PubChem CID 76969187 and PubChem CID 76969188.

The Malaria tab on this ligand page provides additional curator comments of relevance to the Guide to MALARIA PHARMACOLOGY.

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.
