GtoPdb Ligand ID: 5535

Synonyms: Aralen® | chloraquine | Malaquin®
chloroquine is an approved drug (FDA (1949), UK (2000))
Compound class: Synthetic organic
Comment: Chloroquine is a 4-aminoquinoline and used primarily as an antimalarial drug.
The approved drug is a racemic mixture and we show the chemical structure without stereochemistry to represent the mixture. The non-isomeric structure is also represented in the PubChem, ChEMBL and ChEBI entries listed in the links table below, while the two enantiomers forming the racemate are represented by PubChem CID 444810 and PubChem CID 639540. The PDB entry listed in the links table is for (R)-chloroquine.
Marketed formulations may contain chloroquine phosphate (PubChem CID 64927).
