Result:Modestly reduced tumor growth rate, resulting in a tumor growth inhibition (TGI) index of 34% and final average tumor volume of 600 mm3 at 20 days of treatment (10 mg/kg).
Caused significant tumor regression, with a TGI index of 127%, 86% tumor shrinkage, and final average tumor volume of 30 mm3 at 20 days of treatment (100 mg/kg).
Increased time to tumor failure (defined as 2x increase in pre-treatment volume; p=0.044) (100 mg/kg).
Increased percentage of TUNEL-positive apoptotic cells (p=0.015) and p53-positive cells (p<0.001) in tumor tissue, with p53 localization shifted from nuclear to cytoplasmic (100 mg/kg).
Increased p53 and phospho-p53 (Ser392) protein levels in tumor lysates (50 or 100 mg/kg).
Showed no observable weight loss in all treatment groups.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.70 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.
