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. Cutaneous hyperpigmentation during therapy with hydroxychloroquine Plaquenil medication for lupus Hydroxychloroquine weight based dosing 5 mg kg ideal bo Chloroquine phosphate for uronema marinum treatment Apr 21, 2015 A 2-μM concentration of chloroquine fully arrests layer generation and step advancement, which is ∼10 4 × less than hematin’s physiological concentration. Our results suggest that adsorption at specific growth sites may be a general mode of hemozoin growth inhibition for the quinoline antimalarials. 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. PH of food vacuole of plasmodium specie is acidic while chloroquine is a weak base, leading to change in pH of food vacuole. After entry, outer layer of food vacuole becomes water soluble non-lipid soluble so trapped inside food vacuole. 2. Hemozoin affinity for chloroquine 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.

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. 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. Dec 29, 2017 Chloroquine is an antimalarial drug. Malaria invade RBCs and degrade the hemoglobin to utilize their amino acids. However heme molecules are toxic to malarial cells, therefore malaria polymerize.
