摘要
Artemisinin and its derivatives, a class of antimalarial drugs, were first isolated from Artemisia annua. Artemisinin can alter the pH of the malaria parasite’s digestive vacuole from acidic to alkaline, leading to parasite death. However, the precise mechanism of artemisinin action in changing the digestive vacuole pH has not yet been confirmed. Previous studies reported that artemisinin and its derivatives could kill the parasites through the generation of oxidative stress by the free radicals they generate. This review aims to provide a better understanding of the possible mechanism of action of artemisinin, focusing on the antimalarial activity caused by the generated free radicals through the induction of mutation in the genes that encode the proton pump of the Plasmodium falciparum digestive vacuole.
