Although a heme oxygenase HO homologue was found in P. falciparum, it lacks key catalytic residues and does not degrade heme. Interference with hemozoin formation appears to be the mechanism by which many antimalarials, such as chloroquine, exert their antiparasitic activities 11, 12. This mode of action may suggest that generation of. Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function.
