    Chloroquine cytotoxic hemozoin falicparum


    Previously referred to as “Resochin”, Chloroquine was first discovered in 1924 at Bayer laboratories. Its first use was initially ignored as it was found to be toxic to people.

    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. Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. The present study involves synthesis of ten chalcones with various substitution pattern in rings A and B and assessment of their anti-malarial efficacy against chloroquine sensitive and chloroquine resistant strains as well as of their cytotoxicity and effect on haemozoin production.

    These trials showed that chloroquine eliminated malaria and was appropriate to be used as an antimalarial drug. Thus, it was not until World War II that the government of the United States sponsored the clinical trials of chloroquine as an antimalarial drug.

  7. The emergence of drug-resistant strains of iPlasmodium falciparum/i is the worst catastrophe that has ever confronted the dedicated efforts to eradicate malaria. This urged for searching other alternatives or sensitizers that reverse chloroquine resistance. In this experiment, the potential of andrographolide to inhibit plasmodial growth and reverse CQ resistance was tested iin vitro/i.

    Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Chloroquine is used extensively in malaria endemic areas in Africa to treat the uncomplicated form of Plasmodium falciparum malaria. However, the efficiency of chloroquine has been severely impacted by the recent development of chloroquine resistant plasmodium falciparum parasites. The development of chloroquine resistance by malaria parasites is increasing at an alarming rate especially in the tropical countries where it is used extensively as an antimalarial drug 2. Hemozoin Biocrystallization in Plasmodium falciparum and the antimalarial activity of crystallization inhibitors. Quinine extracted from the bark of the South American Cinchona spp tree was the first of all antimalarials in western medicine and had been used since the 17th century.
