The Antimalarial Trioxaquine DU1301 Alkylates Heme in Malaria-Infected Mice

ABSTRACT The in vivo alkylation of heme by the antimalarial trioxaquine DU1301 afforded covalent heme-drug adducts that were detected in the spleens of Plasmodium sp.-infected mice. This result indicates that the alkylation capacities of trioxaquines in mammals infected with Plasmodium strains are similar to that of artemisinin, a natural antimalarial trioxane-containing drug.
