Topotecan Hydrochloride (SKF 104864A Hydrochloride) obviously inhibits the 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 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[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.54 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.54 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Protocole
The U251, U87, GSCs-U251 and GSCs-U87 cells are seeded at a density of 2×104 cells per well in 96-well plates separately, and incubated for 24 h. Cells are administered with Shikonin and Topotecan Hydrochloride (0.02, 0.2, 2, 20, 40 μM). After the treatment, 10 μL of cell counting kit-8 (CCK-8) is added into each well for additional 1-hour incubation at 37°C. The optical density (OD) is read with a microplate reader at 450 nm[1].

Mice[2]
For subcutaneous xenograft studies, we used SK-N-BE, SH-SY5Y, KHOS, and RH30. 1×106 cells are implanted subcutaneously into the inguinal fat pad of each of nonobese diabetic/severe combined immune deficient (NOD/SCID) mice. When tumors reached 0.5 cm in diameter, the animals are randomized into 4 groups and treated daily by oral gavage. The animals are grouped as: Control group, LDM Topotecan group or LDM TP (1 mg/kg Topotecan), Pazopanib group or PZ (150 mg/kg Pazopanib) and combination group or TP + PZ (1 mg/kg Topotecan Hydrochloride + 150 mg/kg Pazopanib). To compare pulse Topotecan with LDM TP in KHOS osteosarcoma model, PZ is replaced by weekly oral dose of pulse Topotecan or Pulse TP (15 mg/kg Topotecan). The criteria for endpoint are tumor sizes exceeding 2.0 cm in diameter or animals showing signs of morbidity. The tumor sizes are measured on a daily basis until the endpoint or sacrifice. The long (D) and short diameters (d) are measured with calipers. Tumor volume (cm3) is calculated as V=0.5×D×d2. When the endpoint is reached or at the end of the treatment, the animals are sacrificed by cervical dislocation.
