IC50: EGFR
Cyasterone exerts cytotoxicity on multiple cell lines: HeLa (IC 50 =77.24 μg/ml); HepG-2 (IC 50 =52.03 μg/ml); MCF-7 (IC 50 =82.07 μg/ml) and MCF-7 (IC 50 =82.07 μg/ml). And It has none cytotoxicity (IC 50 >400 μg/ml) on 3 types of carcinoma (HT-29, Caco-2, T47D) and 1 type of normal (NIH 3T3) cell lines. Cyasterone (0-60 μg/ml; 48 hours) causes a significantly decreasing of the cell proliferation. It inhibits cell growth as a dose-dependent manner, exhibits IC 50 values of 38.50 μg/ml and 32.96 μg/ml, respectively. Cyasterone (0-60 μg/ml; 24 hours) decreases p-EGFR, p-MEK, and p-mTOR as a dose-dependent manner in A549 cells, it affects the MAPK signaling pathway activities.
