Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death. The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex.

Heme = Protoporphyrin IX ring + Iron Fe in center Protoporphyrin IX = porphyrin with attachment to 4 Methyl, 2 Propionyl and 2 Vinyl groups. Porphyrin = Cyclic The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex. Chloroquine inhibits trophozoite hemoglobin degradation through increasing vacuolar pH and inhibiting the activity of vacuolar phospholipase, vacuolar proteases, and heme polymerase. Chloroquine possesses definite antirheumatic properties. Chloroquine possesses definite antirheumatic properties. Chloroquine has immuno-modulatory effects, suppressing the production/release of tumour necrosis factor and interleukin 6. Chloroquine inhibits trophozoite hemoglobin degradation through increasing vacuolar p H and inhibiting the activity of vacuolar phospholipase, vacuolar proteases, and heme polymerase.

This adds to the body of evidence suggesting that chloroquine resistance is a result of failure of drug to reach the target site, rather than alteration of the target itself. A Common Mechanism for Blockade of Heme Polymerization by.. Chloroquine diphosphate ≥99%HPLC Selleck ATM/ATR.. On the molecular mechanism of chloroquine's antimalarial action PNAS. Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. 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 results indicate that chloroquine may be acting by inhibiting haem detoxification/binding to Pfhrp-2. Moreover, the higher affinity of chloroquine for haem than Pfhrp-2 suggests a possible mechanism of action for chloroquine; it may remove the haem bound to Pfhrp-2 and form a complex that is toxic to the parasite. Chloroquine binds to heme or FP to form what is known as 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.
