Abstract/OtherAbstract:
Nowadays, artemisinins are the mainstay of malaria treatment, but initial indications of resistance against clinically used derivatives are present. In this study, ten new artemisinin derivatives were tested in vitro against Plasmodium falciparum laboratory strains as well as clinical isolates from Gabon. All derivatives were highly active, with 50% inhibitory concentrations (IC(50) values) <13nM in the clinical isolates. The activity of one fluoro-containing derivative did not correlate with that of the parent compound, suggesting a different activity profile. New artemisinin derivatives with different activity profiles are of special interest as they represent an important class of candidates for pre-clinical testing in clinical parasite isolates adapted to currently used artemisinins, since derivatisation is one possible strategy to prolong the clinical usefulness of this important class of antimalarials.
