    Chloroquine heme polymerase


    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 Sulfate is the sulfate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the. Chloroquine is a chemotherapeutic agent for the clinical treatment of malaria. 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.

    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.

  4. A heme polymerase is described. The polymerase is critical in the biology of malaria. By using this novel polymerase, assays useful in developing anti-malaria drugs are made possible. Beyond providing a key for future drug studies and biochemical characterizations, treatments for malaria including quinoline-resistant malarias are made possible.

The mechanism of this blockade has not been established. We incubated cultured parasites with subinhibitory doses of 3Hchloroquine and 3H quinidine. THE incidence of human malaria has increased during the past 20 years; 270 million people are now estimated to be infected with the parasite1. An important contribution to this increase has been.
