Activated by the intra-parasitic haem to irreversibly decompose, generating free radicals that alkylate and oxidises proteins and lipids. The membrane of the parasite is damaged by lipid peroxidation and channel proteins inactivation.ubulin alpha-3 chain antagonist; Tubulin beta-2C chain antagonist; substrate for Cytochrome P450 3A4; induces Cytochrome P450 1A1; inhibits Multidrug resistance protein 1.
