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. How to say plaquenil What natural resources are in chloroquine 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. Artemisinin is an ancient Chinese herbal therapy for malarial fevers which has been recently found to have potent activity against many forms of malarial organisms, including chloroquine-resistant Plasmodium falciparum. The following article looks at the medicinal chemistry of antimalarial drugs. It will look at – in detail – quinine and quinine-related drugs. In a previous article, we briefly described malaria and artemisinin as a lead compound for new antimalarials. We now turn our attention to the other antimalarial drugs. 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.

It was discovered in 1972 by Tu Youyou, who was co-recipient of the 2015 Nobel Prize in Medicine for her discovery. Artemisinin - Wikipedia. Medicinal Chemistry of Antimalarial Drugs. Chloroquine - Wikipedia. Artemisinin was first announced to the rest of the world in 1979. At first, biological chemists were puzzled by the apparent stability of the hitherto unknown 15-carbon sesquiterpene peroxide structure. A full chemical synthesis was reported 4 years later, although, as for quinine, this remains too expensive for commercialization. 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. Amodiaquine is a 4-aminoquinolone anti-malarial drug similar in structure and mechanism of action to chloroquine. Amodiaquine has tended to be administered in areas of chloroquine resistance while some patients prefer its tendency to cause less itching than chloroquine.
