    An aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine. The 4-aminoquinoline drug hydroxychloroquine HCQ is reported to be as active as chloroquine CQ against falciparum malaria, and less toxic. Existi. 1 + 10 pKa. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion.

    Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. Chloroquine is a lysosomotropic agent as it is usually prepared as a diprotic weak base pKa 8.5. The unprotonated form of chloroquine preferentially accumulates in lysosomes as it rapidly diffuses across cell/organelle membranes.
