SCS (0.1 nM-3 μM) produces a concentration-dependent inhibition of GABA EC20 currents recorded from Ltk- cells expressing α2β1γ1θ, α2β1γ1 and α1β1γ2s receptors compared with α2β3γ2s and α1β2γ2s receptors upon which SCS has no effect[1].
Inhibition by SCS is not voltage or use dependent[1].
Structural determinants necessary for the inhibition of GABAA receptors by SCS are located within the region arginine 238 and glycine 335 of the β1 subunit. T255 and I308 of the β1 subunit are required for inhibition by SCS[1].

SCS (10-75 mg/kg; i.p.; once) shows antinociceptive activity against tonic, phasic and Capsaicin (HY-10448) nociception in mice[2].
SCS (10-75 mg/kg; i.p.; once) shows anti-inflammatory activity in mice[2]. SCS (50 and 75 mg/kg; i.p.; once) shows antinociceptive activity against neuropathic nociception[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: ≥ 0.56 mg/mL (2.19 mM); Clear solution
This protocol yields a clear solution of ≥ 0.56 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.6 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.

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 .
