How to use

In Vitro:

Dihydroartemisinin (DHA) is an antimalarial agent. Dihydroartemisinin treatment effectively up-regulates the cytosolic RelA/p65 protein level and down-regulates the nuclear RelA/p65 protein level. Dihydroartemisinin blocks the nuclear translocation of RelA/p65 from the cytosol rather than suppressing RelA/p65 protein synthesis. Dihydroartemisinin induces autophagy in RPMI 8226 cells. Dihydroartemisinin suppresses NF-κB activation in RPMI 8226 cells. The NF-κB Dihydroartemisinin -binding activity is examined by EMSA assay. RPMI 8226 cells are exposed to various concentrations of Dihydroartemisinin (10, 20 and 40 μM) for 12 h, and TNF-α is introduced as a positive control for NF-κB activation. Dihydroartemisinin suppresses NF-κB activation in a dose-dependent manner in contrast with TNF-α. Dihydroartemisinin (DHA) can enhance the anti-tumor effect of photodynamic therapy (PDT) on esophageal cancer cells, and cell viability is investigated using the MTT assay. Eca109 and Ec9706 cells are treated with Dihydroartemisinin (80 μM), PDT (25 and 20 J/cm2, respectively) or their combination. Single treatment with Dihydroartemisinin or PDT causes a 37±5% or 34±6% reduction in viability in Eca109 cells and a 33±7% or 34±6% reduction in Ec9706 cells, respectively. However, when PDT is combined with Dihydroartemisinin, the cell viability is reduced 59±6% or 61±7% in the cell lines, respectively.

In Vivo:

Single oral doses of Dihydroartemisinin (at 200, 300, 400 or 600 mg/kg), given once on each of day 6-8 post-infection, reduce total-worm burdens by 69.2%-90.6% and female-worm burdens by 62.2%-92.2%, depending on dosage in the first experiment. Similar treatments given on day 34-36 post-infection reduce total-worm burdens by 73.9%-85.5% and female-worm burdens by 83.8%-95.3%.
