Primaquine is a synthetic, 8-aminoquinoline derivative that has potent antimalarial activity. It is effective against all exoerythrocytic forms of the malaria parasite, including the hypnozoite and is also active against the sexual blood stage (gametocytes). Primaquine is the only approved drug that is currently available for terminal prophylaxis to prevent relapse or delayed-onset clinical presentation of P. vivax and P. ovale malaria.
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 3044368 and PubChem CID 3044369.
The marketed formulations contain primaquine phosphate (PubChem CID 6135).
Primaquine is one of the antimalarials listed in the WHO 20th Essential Medicines List (2017).

Potential Target/Mechanism Of Action: As the precise mechanism of action of primaquine is not yet known, we do not have a molecular target for this compound.
