    Chloroquine hemazoin


    These hematophagous organisms such as Malaria parasites (Plasmodium spp.), Rhodnius and Schistosoma digest haemoglobin and release high quantities of free heme, which is the non-protein component of hemoglobin. Heme is a prosthetic group consisting of an iron atom contained in the center of a heterocyclic porphyrin ring.

    Chloroquine is thought to exert its antimalarial effect by preventing the polymerization of toxic heme released during proteolysis of hemoglobin in the Plasmodium digestive vacuole. The mechanism of this blockade has not been established. We incubated cultured parasites with subinhibitory doses of 3Hchloroquine and 3H quinidine. These 3Hquinoline compounds became associated with hemozoin. In malaria parasites, hemozoin is often called malaria pigment. Since the formation of hemozoin is essential to the survival of these parasites, it is an attractive target for developing drugs and is much-studied in Plasmodium as a way to find drugs to treat malaria malaria's Achilles' heel. A 2-μM concentration of chloroquine fully arrests layer generation and step advancement, which is ∼10 4 × less than hematin’s physiological concentration. Our results suggest that adsorption at specific growth sites may be a general mode of hemozoin growth inhibition for the quinoline antimalarials.

    In malaria parasites, hemozoin is often called malaria pigment. Free heme is toxic to cells, so the parasites convert it into an insoluble crystalline form called hemozoin.

  6. Chloroquine forms a drug-hemozoin complex, and this complex caps the polymerizing chain, thereby preventing additional polymerization. Along with the prevention of polymerization, the free heme accumulates in the food vacuole, exerting its toxic effects on the parasite. Chloroquine also functions as an anti-autoimmune therapy.

    The ability of chloroquine to inhibit hemozoin formation suggests that this and related compounds may be interfering with the heme-detoxification process, making the parasites susceptible to oxidative stress by heme. 187,188 The exact molecular details of this interference have been the subject of much discussion, and studies over the last. Mechanism of action Chloroquine basic concentrates in parasite food vacuole acidic. Prevent heme polymerization into hemozoin causing heme accumulation toxic to parasite. Drug complex with heme disrupt cell membrane function. Other mechanism include intercalating of parasite DNA, DNA synthesis inhibition. 7. Artemisia annua tea stronger than chloroquine ! August 10, 2013 - -- Pierre Lutgen Recent results obtained at the AlQuds University in partnership with IFBV-BELHERB from Luxembourg show that freshly prepared infusion of Artemisia annua is stronger than chloroquine in the inhibition of beta-hematin hemozoin formation.
