Quinacrine: mechanisms of antimalarial action

Two new interesting modes of action of quinacrine have been discovered. The first concerns a dose-related inhibition of uptake of 8-(3)H] adenosine into host cells of parasitized blood. Second, the drug inhibits the incorporation of tritiated adenosine triphosphate primarily into RNA but also into DNA of the erythrocyte-free malarial parasite Plasmodium berghei.
