    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.

    Hemozoin collects in the digestive vacuole as insoluble crystals. citation needed Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. 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. Aug 10, 2013 Artemisia annua tea stronger than chloroquine ! August 10, 2013 - -- Pierre Lutgen Recent results obtained at the AlQuds University in partnership with IFBV-BELHERB from Luxembourg show that freshly prepared infusion of Artemisia annua is stronger than chloroquine in the inhibition of beta-hematin hemozoin formation.

    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.

    The ability of chloroquine to inhibit hemozoin formation suggests that this and related compounds may be interfering with the heme-detoxification process, making the parasites susceptible to oxidative stress by heme. 187,188 The exact molecular details of this interference have been the subject of much discussion, and studies over the last. 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. Chloroquine forms a drug-hemozoin complex, and this complex caps the polymerizing chain, thereby preventing additional polymerization. Along with the prevention of polymerization, the free heme accumulates in the food vacuole, exerting its toxic effects on the parasite. Chloroquine also functions as an anti-autoimmune therapy.
