生物活性

Artemisinin (Qinghaosu), a sesquiterpene lactone, is an anti-malarial drug isolated from the aerial parts of Artemisia annua L. plants[1]. Artemisinin inhibits AKT signaling pathway by decreasing pAKT in a dose-dependent manner. Artemisinin reduces cancer cell proliferation, migration, invasion, tumorigenesis and metastasis and has neuroprotective effects[2].

IC50 & Target[2]

pAKT

 

体外研究
(In Vitro)

Artemisinin (Qinghaosu) (25 or 50 μM; 24 hours) concentration-dependently suppresses Aβ25-35 induced cytotoxicity in PC12 cells[1].
Artemisinin (1-100 μM; 24  hours) selectively inhibits cancer cell growth in a dose-dependent manner with IC50 values of 31.30 ± 0.73 μM in UMRC-2 cells and 23.97 ± 0.92 CAKI-2 cells[2].
Artemisinin (25, 50 μM; 24 hours) suppresses the phosphorylation of AKT in UMRC-2 and CAKI-2 cells in a dose-dependent manner[2].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
