The antimalarial activity of peroxides most likely originates from their interaction with iron(II) species located inside the malaria parasite, which forms destructive radical species through a Fenton-like mechanism. This article reports the first evaluation of the in vitro antimalarial activity of three peroxides of the class 1,2-dioxetanes against Plasmodium falciparum; the results reveal that the studied 3-methoxy-1,2-dioxetanes display significant antimalarial activity, at a similar level as artemisinin and also that their reactivity toward iron(II) correlate linearly with their antimalarial activity.
Keywords: 1,2-dioxetanes; Fenton reaction; Plasmodium falciparum; antimalarial peroxides.
