Trioxaferroquines as New Hybrid Antimalarial Drugs

The synthesis, characterization, and antimalarial evaluation of a new series of potential antimalarial molecules, named trioxaferroquines, are reported. Trioxaferroquines are hybrid antimalarial drugs containing a 1,2,4-trioxane covalently linked to ferroquine (Fq), a synthetic ferrocenylquinoline derivative currently under clinical development. The aim was to combine, within a single structure, an iron(II) species, a 1,2,4-trioxane, as in artemisinin, and a substituted quinoline, as in chloroquine.
