    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.

    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. 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 Chloroquine resistant Plasmodium berghei release measurable hemozoin into tissues with blood hemozoin 100 times less per parasite while total in all tissues is only 5 times less than chloroquine sensitive. Chloroquine resistant P. bergheihemozoin crystals are morphologically smaller but similar to those formed by chloroquine sensitive parasites.

    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.

  5. This chapter briefly discusses the association between chloroquine resistance and the malaria pigment, haemozoin. Also presented are short biographies of David Warhurst and David Fidock, which highlight their contributions to the study of antimalarial drug resistance.

    The general accepted conclusion is that chloroquine interferes with the process in which heme is converted to hemozoin 10. Chloroquine concentrates in the food vacuole up to 1000-fold. Chloroquine, exists in unprotonated form, CQ, monoprotonated form, CQ + and diprotonated form, CQ ++ form 13. Unprotonated form of chloroquine is membrane. 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. The quinoline-related or quinoline-like compounds quinine, quinidine, chloroquine, amodiaquine, mefloquine, halofantrine, lumefantrine, piperaquine, pyronaridine chemically interfere with intraparasitic heme detoxification, preventing the dimerization process that results in the formation of hemozoin malaria pigment.

    Synthesis of chloroquine from 4-amino-7-chloroquinoline It's a pretty untypical approach to chloroquine and you didn't tell how you would synthesize 7-chloro-3-aminoquinoline and the secondary chloride. There is a good chance that the planned reaction will furnish a quarternary ammonium salt as a side product The reaction will not necessary stop at this point.

    Terrible Itching on Plaquenil---PLEASE HELP. Pill a day of the brand name Plaquenil. Three months later in early May the back of my head began itching. It is STILL causing me grief. Then 3 weeks after the back of my scalp began itching, my upper left shoulder broke out in a bumpy, itchy rash.

    Plaquenil hydroxychloroquine 200mg is it causing itchy.
