Malarial parasites invade human red blood cells. In our study, neither bafilomycin nor chloroquine for 32 min changed OCR in intact cells Supplemental Figure 2A. These data indicate that the observed deficits in mitochondria function are not due to off target effects of the compounds on mitochondria but rather through autophagy failure resulting in accumulation of damaged mitochondria. Chloroquine CQ accumulates in the food vacuole of the parasite. This accumulation may involve ion trapping following protonation, specific transport, and/or binding to a receptor eg. heme. The major action of chloroquine is to inhibit the formation of hemozoin Hz from the heme released by the digestion of hemoglobin Hb.

The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain.

These side effects can often be lessened by taking chloroquine with food. Chloroquine may also cause itching in some people. All medicines may have some side effects. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. In essence, the parasite cell drowns in its own metabolic products.
