Dihydroartemisinin induces caspase-8-dependent apoptosis in murine GT1-7 hypothalamic neurons

The cytotoxicity of dihydroartemisinin (DHART; an active metabolite of artemisinin or ART) was investigated using murine GT1-7 hypothalamic neurons. A decrease in neuronal cell viability was observed in DHART-treated cells typically after 6 h of incubation. When neuronal cells were exposed to DHART for 24 h, the value of IC50 was found to be 24 ± 3.2 µM (n = 6). Based on acridine orange/ethidium bromide (dual) staining and increases in...
