    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 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. Worldwide, they infect about 500 million, incapacitate tens of millions, and kill approximately 2.5 million mostly children annually. Four species infect humans, but most deaths are caused by one particular species, Plasmodium falciparum. The rising number of malarial deaths is due in part to increased drug resistance in P. falciparum. There are many varieties of antimalarial drug resistance, and there may very well be several molecular level contributions to each variety. 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.

    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.

Well-developed SAR models exist for β-hematin inhibition, parasite activity, and cellular mechanisms for this compound class, but no comparably detailed investigations exist for other hemozoin inhibiting chemotypes. Here, benzamide analogues based on previous HTS hits.

    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. 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.
