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. Side effects hydroxychloroquine sulfate 200 mg Plaquenil drug monograph No. 3, 1990 77 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. Chloroquine Phosphate is the phosphate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase. Chloroquine diphosphate salt is used to study the role of endosomal acidification in cellular processes, such as the signaling of intracellular TLRs. It can be used as DNA intercalator & to dissociate antigen antibody complexes without denaturing red blood cell antigens. 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.

Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Chloroquine Oral Uses, Side Effects, Interactions.. Chloroquine diphosphate salt, 98% - N4-7-Chloro-4-quinolinyl.. Analysis of chromatin structural transitions by means of.. Mg chloroquine base/5 ml syrup. The dose written on the labels is sometimes in chloroquine salt and sometimes in chloroquine base which leads to frequent confusion. The WHO recommends prescriptions and labels in chloroquine base. 100 mg base = approx. 130 mg sulfate = approx. 160 mg phosphate or diphosphate For each chloroquine concentration, the specific ac- tivity of chloroquine was calculated cpm mmo1-1 and then used to convert from cpm to concentra- tion. Binding analysis. The 'bound' chloroquine con- centration was determined by subtracting the 'free' external concentration from the 'free + bound' internal concentration. Chloroquine diphosphate salt is used to study the role of endosomal acidification in cellular processes, such as the signaling of intracellular TLRs. It can be used as DNA intercalator & to dissociate antigen antibody complexes without denaturing red blood cell antigens. Chloroquine showed very high antiviral activity against NiV.
