Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance. How much hydroxychloroquine can i take Hydroxychloroquine also known as Chloroquine lysosomal inhibitor transfection Chloroquine definition is - an antimalarial drug C18H26ClN3 administered in the form of its bitter crystalline diphosphate. Background. The spread of resistance to chloroquine CQ led to its withdrawal from use in most countries in sub-Saharan Africa in the 1990s. In Malawi, this withdrawal was followed by a rapid reduction in the frequency of resistance to the point where the drug is now considered to be effective once again, just nine years after its withdrawal. Chloroquine is a member of an important series of chemically related anti-malarial agents, the quinolone derivatives. Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II . These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

Chloroquine - definition of chloroquine by The Free Dictionary. Mechanisms of drug action and resistance. Mass nounMedicine. A synthetic drug related to quinoline, used against malaria. ‘Doctors treat malaria by using anti-malarial drugs, such as chloroquine or quinine.’. ‘Quinine formed the basis for synthesising the commonly used antimalarial drugs, chloroquine and mefloquine.’. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. An antimalarial and antiprotozoal agent, also used as a lupus erythematosus suppressant. 2. an antiamebic and antiinflammatory agent used in treatment of malaria, giardiasis, non-intestinal amebiasis, lupus erythematosus, and rheumatoid arthritis; used as the base, hydrochloride salt, or phosphate salt.
