| Protocol | In Vitro | Topotecan Hydrochloride (SKF 104864A Hydrochloride) obviously inhibits proliferation of not only human glioma cells but also glioma stem cells (GSCs) in a dose- and time-dependent manner. According to the IC50 values at 24 h, 3 μM of Topotecan Hydrochloride is selected as the optimal administration concentration. In addition, Topotecan Hydrochloride induces cell cycle arrest in G0/G1 and S phases and promoted apoptosis. Results show that the cell viability is inhibited by Topotecan Hydrochloride in a dose-dependent manner. 2, 20 and 40 μM of Topotecan Hydrochloride obviously inhibits the cell viability compared with the control groups. The IC50 values of Topotecan Hydrochloride at 24 h are 2.73±0.25 μM of U251 cells, 2.95±0.23 μM of U87 cells, 5.46±0.41 μM of GSCs-U251 and 5.95±0.24 μM of GSCs-U87. Thus 3 μM of Topotecan Hydrochloride is selected as the optimal administration concentration in the subsequent experiments |
