Aralen (Chloroquine) is an antimalarial drug derived from 4-aminoquinoline. It provides a pronounced and rapid schizontocidal effect. In the process of their development in red blood cells, parasites secrete the degradation product of ferriprotoporphyrin IX, which is a chloroquine receptor.

Aralen property to concentrate inside red blood cells damaged by parasites provides selective drug toxicity in relation to the erythrocyte phase of plasmodium infection.
