Sample Use Guides

In Vivo Use Guide

In clinical trials, Artefenomel is administered in 800 mg doses in loose combination with Piperaquine phosphate doses of either 640, 960, 1440 mg

Route of Administration: Oral

In Vitro Use Guide

Asexual parasites were seeded at a density of 0.5% parasitemia in 3% hematocrit in a black 384-well plate in 30 μL of culture medium, and 30 μL of diluted compound was added. Following a 72 h incubation at 37°C, 98% humidity, 93% N2, 4% CO2 and 3% O2, the increase in parasitemia was assessed using the modified Plasmodium lactate dehydrogenase assay. Artefenomel was diluted in DMSO and subsequently in culture medium to reach a final DMSO concentration of 0.1%.
