Real-time imaging of the intracellular glutathione redox potential in the malaria parasite Plasmodium falciparum.
... Artemisinin-based (Fig. S6 B–D) antimalarials at 100 m M did not rapidly (within 5 min) oxidize the parasites’ cytosol. This result is consistent with the fact that artemisinin derivatives produce carbon-centered free ...
