    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.

    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. 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, an antimalarial drug, can also be used in the manipulation of the immune system. • This review demonstrates the multitude of actions displayed by CQ, dependent on lysosome dysfunction and also pH-independent mechanisms.

    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.

  4. The proteolysis of Hb is accompanied by the release of free heme, which is cytotoxic for the parasite and is rapidly detoxified and converted into hemozoin Hz. Therefore, both Hb degradation and heme detoxification are considered to be essential for P. falciparum survival Goldberg, 2005. The digestion of Hb is a conserved and semiordered process, which principally occurs within the acidified digestive vacuole DV.

    Chloroquine was known to exert its activity by accumulating in parasite DV and so compromising hemoglobin digestion by the parasite leading to the accumulation of toxic compounds that eventually kill the parasite. In CQ-resistant P. falciparum strains, chloroquine accumulates in a much-reduced degree than in sensitive ones. Therefore, drug transport is believed to be of crucial importance for understanding the mechanisms of chloroquine resistance. It acts by inhibiting the hemozoin biocrystallization, thus facilitating an aggregation of cytotoxic heme. Quinine is less effective and more toxic as a blood schizonticidal agent than chloroquine ; however, it is still very effective and widely used in the treatment of acute cases of severe P. falciparum. Quinoline antimalarials target hemozoin formation causing a cytotoxic accumulation of ferriprotoporphyrin IX FeIIIPPIX. 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.
