    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.

    Possible results of the assay Substrate Compound a Relaxed DNA Compound is an intercalator but not a topo I inhibitor. The intercalation leads to a decreased twist and a consequent increased writhe positive supercoils. The topo I relaxes the DNA so writhe becomes zero. Oct 01, 2018 The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA. Chloroquine as Intercalator a Hypothesis Revived S. R. Meshnick The mode of action of chloroquine is still controversial. Proposed mechanisms of action include I DNA intercalation, 2 lysosome accumulation and 3 binding to ferriprotoporphyrin IX. Recent data sug- gest that intercalation into parasite DNA

    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.

  7. Chloroquine diphosphate is used as an antimalarial drug and also functions to increase sensitivity of tumor cells to radiation and chemotherapy via inducing autophagy 1. Chloroquine diphosphate has been reported as an adjuvant for radiation and chemotherapy for inducing cell autophagy to anti-cancer cells proliferation or metastasis 2.

    Chloroquine is an inhibitor of the lysosomal degradation of the DNA which is taken up by the cells, so as leelee said, transfection should have been successful, albeit at a slightly lower level than if you would have added the chloroquine. Chloroquine is a critically important antimalarial drug and a well known intercalator into DNA. We now show that chloroquine binds more avidly to polydG-dCpolydG-dC than to other synthetic polynucleotides and that this binding inhibits both salt- and cobalt-induced transitions to Z-DNA. Title Nucleus may be the key site of chloroquine antimalarial action and resistance development. Abstract The first proposed hypothesis about the mechanism of chloroquine CQ action on malaria parasites is DNA intercalation hypothesis which indicates that the site of CQ action is within the nucleus.

    Chloroquine MedlinePlus Drug Information For treatment of amebiasis, one dose is usually taken for 2 days and then half the dose every day for 2 to 3 weeks. It is usually taken in combination with other amebicides. Chloroquine phosphate may cause an upset stomach.
