|Hydroxychloroquine 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 178395 and PubChem CID 178396.
The marketed formulations contain hydroxychloroquine sulfate (PubChem CID 3044369).
Activity at non-malarial protein targets:
Although this drug has direct effects on survival of the malaria parasite it also appears to be an antagonist of two of the human TOLL-like receptors (TLR7 and TLR9). Antagonism of these receptors is likely related to the anti-inflammatory action of this drug in some auto-immune diseases.
