生物活性
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
8-Epidiosbulbin E acetate can be used in animal modeling to create liver injury models. Pre-treatment with Ketoconazole (KTC) prevents liver injury caused by 8-Epidiosbulbin E acetate and increases the Cmax and AUC of 8-Epidiosbulbin E acetate in plasma by 7-fold and 13-fold, respectively, while reducing the urinary excretion of glutathione (GSH) conjugates derived from 8-Epidiosbulbin E acetate[1][2].
8-Epidiosbulbin E acetate mainly damaged hepatic cells through the aberrant regulation of multiple systems primarily including bile acid metabolism, and taurine and hypotaurine metabolism. In addition, an imbalance of bile acid metabolism was found to play a key pat in response to 8-Epidiosbulbin E acetate-triggered hepatotoxicity[2].
Administration: 50-150 mg/kg• i.p.• a single dose for 12, 24, 36, and 48 h[1]
Mice: ICR• male• 4-5 weeks of age• weighing: 18-22 g[2]
Administration: 150 mg/kg•p.o.•a single dose for 36 h[2]
(2) 8-Epidiosbulbin E acetate (100 mg) was individually suspended in 10 mL of corn oil[1].
(3) 8-Epidiosbulbin E acetate was suspended in 0.5% CMC-Na[2].
Pathology change: 8-Epidiosbulbin E acetate administration showed inflammatory cell infiltration, hepatic cell necrosis and focal necrosis in mice[2].
Metabolic change: 8-Epidiosbulbin E acetate administration elevated phenylalanine, tyrosine and tryptophan biosynthesis. Moreover, several other important pathways, including citrate cycle (TCA cycle), phenylalanine metabolism, β-alanine metabolism and taurine and hypotaurine metabolism, were activated in both serum and livers[2].

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 (6.44 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 (6.44 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.
