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. It has been detected in the plasma, red blood cells, and urine of patients 5 years after their last known ingestion. 27 This prolonged presence may account for the rare cases of delayed onset of chloroquine retinopathy seen up to 7 years or longer after discontinuation. 28, 29.

The use of chloroquine in combination with other chemotherapeutic reagents may enhance cancer treatment 8, 29, but normal cells also use autophagy to maintain homeostasis, and inhibition of autophagy by chloroquine may sensitize not only cancer cells, but also normal organs to chemotherapy. The combination of chloroquine with zinc enhanced chloroquine’s cytotoxicity and induced apoptosis in A2780 cells. Thus chloroquine is a zinc ionophore, a property that may contribute to chloroquine’s anticancer activity. Chloroquine inhibits the intracellular multiplication of Legionella pneumophila by limiting the availability of iron.
