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: ≥ 0.5 mg/mL (1.39 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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: ≥ 0.5 mg/mL (1.39 mM); Clear solution
This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
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.
Protocol
IL-1, IL-6 and TNF-a are induced by i.p. injection of LPS into BALBIc mice. SR 31747 or reference substances are administered i.p. at the indicated doses together with LPS (0.5 mg/kg). Control animals are treated with LPS and vehicle. Blood samples are collected from the retro-orbital sinus 1 hr or 4 hr after LPS injection for the determination of TNF-α, IL-1 and IL-6. Plasma is prepared and stored frozen until experiments. The IL-1 plasma level is determined by a competitive radioreceptor assay with the use of the murine NOBEL4 cell line and [125I]-IL-1. The IL-6 assay is conducted with the B9 murine IL-6-dependent cell line. The TNF-a plasma level is evaluated by the cytolytic assay with the dactinomycin-treated LM6 cell line, derived from the murine fibroblastic L929 cell line. Each determination is performed on a pool of three different plasma samples. None of the molecules administered affect these assays even at the highest dose (10-5 M), which thereby rules out the possibility of any direct effect caused by the presence ofdrugs in treated-animal sera. In the various tests, one unit is defined as the amount of cytokines able to induce 50% of the maximal effect.
