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. Autophagy inhibitors hydroxychloroquine Chloroquine route of administration Dominic Kwiatkowski and colleagues report a large multicenter genome-wide association study of Plasmodium falciparum resistance to artemisinin. They identify markers of a genetic background on. Artemisinin or qinghaosu was isolated by Chinese researchers in 1972 from Artemisia annua, L. sweet or annual wormwood, and its structure was elucidated in 1979 Klayman, 1985. The plant has been used in traditional Chinese medicine as a remedy for chills and fevers for more than 2000 years. Artemisinin / ˌ ɑː t ɪ ˈ m iː s ɪ n ɪ n / and its semisynthetic derivatives are a group of drugs used against malaria due to Plasmodium falciparum. It was discovered in 1972 by Tu Youyou, who was co-recipient of the 2015 Nobel Prize in Medicine for her discovery. 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.

Qinghaosu artemisinin Chemistry and pharmacology. Artemisinin - Wikipedia. Arteannuin C15H22O5 - PubChem. Artemisinin combination therapies are the first-line treatments for uncomplicated P. falciparum malaria in most malaria-endemic countries. Recently, partial artemisinin-resistant P. falciparum malaria has been observed on the Cambodia–Thailand border. Exposure of the parasite population to artemisinin monotherapies in subtherapeutic doses for over 30 years, and the availability of substandard artemisinins have probably been the main driving force in the selection of the resistant phenotype. Artemisinin is one of the few antimalarials for which there is no widespread resistance. In the 1970s the chemical structure of a sesquiterpene peroxide with. Chloroquine was discovered by. Interactions of artemisinin with amodiaquine, pyronaridine, and chloroquine were therefore investigated against three strains of P. falciparum using a 48-h in vitro culture assay. Two of the strains were chloroquine sensitive and one was partially chloroquine resistant.
