Artemisinin (/ˌɑːrtɪˈmiːsɪnɪn/) and its semisynthetic derivatives are a group of drugs used in the treatment of malaria due to Plasmodium falciparum.[1] It was discovered in 1972 by Tu Youyou, who shared the 2015 Nobel Prize in Physiology or Medicine for her discovery.[2] Artemisinin-based combination therapies (ACTs) are now standard treatment worldwide for P. falciparum malaria as well as malaria due to other species of Plasmodium.[3] Artemisinin is extracted from the plant Artemisia annua (sweet wormwood) an herb employed in Chinese traditional medicine. A precursor compound can be produced using a genetically engineered yeast, which is much more efficient than using the plant.[4]
Artemisinin and its derivatives are all sesquiterpene lactones containing an unusual peroxide bridge. This endoperoxide 1,2,4-trioxane ring is responsible for their antimalarial properties. Few other natural compounds with such a peroxide bridge are known.[5]
Artemisinin and its derivatives have been used for the treatment of malarial and parasitic worm (helminth) infections. Advantages of such treatments over other anti-parasitics include faster parasite elimination and broader efficacy across the parasite life-cycle; disadvantages include their low bioavailability, poor pharmacokinetic properties, and high cost.[6][7] Moreover, use of the drug by itself as a monotherapy is explicitly discouraged by the World Health Organization,[8] as there have been signs that malarial parasites are developing resistance to the drug.[9] Combination therapies, featuring artemisinin or its derivatives alongside some other antimalarial drug, constitute the contemporary standard-of-care treatment regimen for malaria.[10]
