Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Chloroquine classification Is methotrexate the same as plaquenil Plaquenil generic drug DNA binding was considered the principal mechanism of action of CQ in the early literature but this hypothesis has been largely abandoned even though CQ is known to bind to DNA and acridine-based antimalarial drugs are believed to act predominantly or partly by DNA binding mechanisms 13-15. The binding site was defined using the C ɛ2 atom of W183, the C ζ atom of Y234 or the C ζ atom of Y153, with a binding site radius of 7 Å for quinine and 10 Å for chloroquine. The amino-acid residues were chosen based on the preferred binding site models of Reeves et al. 2003 and Thompson et al. 2005. Chloroquine is an anti-malarial drug available at pharmacies for people traveling to area with malaria risks. Note based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

Structure and Functional Differentiation of PfCRT Mutation in Chloroquine Resistance CQR in Plasmodium falciparum Malaria, Current Topics in Malaria, Alfonso J. Rodriguez-Morales, IntechOpen, DOI 10.5772/64659. Amodiaquine AQ along with sulphadoxine-pyrimethamine SP offers effective and cheaper treatment against chloroquine-resistant falciparum malaria in many parts of sub-Saharan Africa. Considering the previous history of hepatitis, agranulocytosis and neutrocytopenia associated with AQ monotherapy, it becomes imperative to study the toxicity of co-administration of AQ and SP. In this study. Chloroquine Modes of action of an undervalued drug. For more than two decades, chloroquine CQ was largely and deliberate used as first choice drug for malaria treatment. However, worldwide increasing cases of resistant strains of Plasmodium have hampered its use.
