    Hemozoin chloroquine


    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.

    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. The general accepted conclusion is that chloroquine interferes with the process in which heme is converted to hemozoin 10. Chloroquine concentrates in the food vacuole up to 1000-fold. Chloroquine, exists in unprotonated form, CQ, monoprotonated form, CQ + and diprotonated form, CQ ++ form 13. Unprotonated form of chloroquine is membrane permeable and it freely diffuses into the red blood cell. Chloroquine resistant P. berghei hemozoin crystals are morphologically smaller but similar to those formed by chloroquine sensitive parasites. Chloroquine resistance in P. vivax is distinct from P. berghei even though both infect reticulocytes.

    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.

  3. 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.

    Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. 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. 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. Aug 10, 2013 In the infected erythrocyte the malaria parasite generates large quantities of toxic heme which it has to render innocuous by polymerizing it into hemozoin. The mechanism of quinine and all its derivates, chloroquine, amodiaquine operates by inhibiting this hemozoin crystallization.
