Mechanism of action

Artemisinin is activated by ferrous iron in Plasmodium parasites, creating free radicals that cause oxidative damage to parasite proteins and lipids. Naphthoquine, a quinoline derivative, works synergistically by inhibiting the conversion of toxic heme to hemozoin and disrupting the parasite's mitochondrial electron transport chain. This combination provides rapid parasite clearance and reduces the risk of resistance development.
