Treatment with Erteberel (0.25-10 μM, 72 hours) significantly reduces the proliferation of GBM cells with no activity on normal astrocytes in vitro[2].
Erteberel promotes apoptosis of GBM cells. Erteberel modulated several pathways related to apoptosis, cell cycle, and DNA damage response[2].
Erteberel (0-1000 μM) sensitizes GBM cells to several FDA-approved chemotherapeutic drugs including cisplatin, lomustine and temozolomide[2].

Cell Line:U87, U251,T98G and normal astrocytes
-
Concentration:0.25, 0.5, 1, 2, 4, 6, 8, and 10 μM
-
Incubation Time:72 h
-
Result:Treatment with Erteberel significantly reduces the viability of various GBM cell lines in a dose-dependent manner. In contrast, viability of normal astrocytes is not affected at the tested doses, suggesting that Erteberel has tumor cell–specific activity[2].
Erteberel (5 mg/Kg body weight/day, oral, 40-50 days) treatment improves the overall survival of tumor-bearing mice in the GL26 syngeneic glioma model[2].

Animal Model:Athymic mice (5-7 weeks) inoculated with OVCAR-3 cells[2]
-
Dosage:5mg/Kg body weight
-
Administration:Oral, daily for 28 days
-
Result:Immunohistochemical analysis reveals that Erteberel treatment significantly reduces the number of proliferation marker Ki-67-positive cells and increases the number of TUNEL-positive apoptotic cells[2].

Solvent & Solubility
DMSO : 100 mg/mL (354.20 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 2.5 mg/mL (8.85 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (8.85 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
