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.
Cell Viability Assay
Cell Line: | A549 cells and MGC823 cells |
Concentration: | 0 μg/ml, 20 μg/ml, 40 μg/ml, 60 μg/ml |
Incubation Time: | 24 hours |
Result: | Inhibited cell proliferation as a dose-dependent manner. |
Western Blot Analysis
Cell Line: | A549 cells |
Concentration: | 0 μg/ml, 20 μg/ml, 40 μg/ml, 60 μg/ml |
Incubation Time: | 24 hours |
Result: | Surpressed p-EGFR, p-MEK, and p-mTOR expression. |
Cyasterone (intraperitoneal injection; 5 mg/kg, 10 mg/kg and 15 mg/kg; 21 days) has anti-proliferation effect in vivo and inhibits MGC823 cells xenografted tumor growth in vivo with few changes in body weights.
Animal Model: | MGC823 xenograft tumor in BALB/C-nu mice |
Dosage: | 5 mg/kg, 10 mg/kg and 15 mg/kg |
Administration: | Intraperitoneal injection |
Result: | Inhibited MGC823 xenograft tumor growth in vivo. |
