    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.

    Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. The mutants produce little or no hemozoin Hz, the detoxification by-product of Hb degradation. Further, they are resistant to chloroquine, an antimalarial drug that interferes with Hz formation, but their sensitivity to artesunate, also thought to be dependent on Hb degradation, is retained. Inexpensive and stable antimalarial drugs such as the 7-chloro-4-aminoquinoline derivative chloroquine CQ have kept malaria in check in most regions for decades. However, the rising number of malarial deaths is due in part to increased resistance to CQ and other drugs in P. falciparum.

    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.

    A distinctive attribute of malaria infected red blood cells is the presence of malarial pigment or so-called hemozoin. Hemozoin is a biocrystal synthesized by Plasmodium and other blood-feeding parasites to avoid the toxicity of free heme derived from the digestion of hemoglobin during invasion of the erythrocytes. This chapter analyzes the effect of Chloroquine CQ on hemozoin. The worldwide spread of CQ resistance has led to a significant resurgence of malaria The emergence of drug-resistant strains of iPlasmodium falciparum/i is the worst catastrophe that has ever confronted the dedicated efforts to eradicate malaria. This urged for searching other alternatives or sensitizers that reverse chloroquine resistance. In this experiment, the potential of andrographolide to inhibit plasmodial growth and reverse CQ resistance was tested iin vitro/i.

    Plaquenil and immune system Lupus Forums at The Lupus Site Mar 23, 2014 Plaquenil is not thought to have a strong effect on the immune system with regard to illnesses etc.far as I am aware. I am sure others will be on to share any similar experiences however, I found the plaquenil, if anything very weak for my MCTD.needed steroids too whilst it was kicking in.then Cellcept etc etc

    Is Plaquenil a immunosuppressant drug ? Autoimmune.
