    Chloroquine hemozoin


    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 this case, chloroquine could cap the end of the hemozoin crystal, preventing additional heme units from extending growth. A theoretical model of the interaction of hemozoin and quinolines demonstrates the ability of the protonated drug to noncovalently bind to the fast-growing face of the crystal, but has yet to be confirmed. Even if a. This chapter analyzes the effect of Chloroquine CQ on hemozoin. The worldwide spread of CQ resistance has led to a significant resurgence of malarial morbidity and mortality concomitant with. Hydroxychloroquine and chloroquine have been recommended by Chinese and South Korean health authorities for the treatment COVID-19. In vitro studies have demonstrated that hydroxychloroquine is more potent than chloroquine against SARS-CoV-2 with a more tolerable safety profile.

    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.

    A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen. 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. These 3Hquinoline compounds became associated with hemozoin. Thus, chloroquine inhibits hemozoin production in chloroquine-susceptible P. falciparum but not in chloroquine-re- sistant P. falciparum. On the contrary, sublethal concentrations of chloroquine partially reverse a deficiency of hemozoin production in chloroquine-resistant P. falciparum.
