In the profiling against a panel of 61 kinases, SR7826 (compound 18b) at 1 μM inhibits only Limk1 and STK16 with ≥80% inhibition. SR7826 is highly efficient in inhibiting cell-invasion/migration in PC-3 cells. SR7826 (compound 18b) inhibits cofilin phosphorylation in A7r5 (IC50 = 470 nM) and PC-3 cells (IC50 < 1 μM)[1].
SR7826 (1 μM) inhibits contractions of prostate strips, which were induced by electrical field stimulation and inhibits cofilin phosphorylation in prostate tissues and cultured stromal cells (WPMY-1). In WPMY-1 cells, SR7826 causes breakdown of actin filaments and reduced viability[3].

The plasma pharmacokinetics studies on rats are investigated. After intravenous injection, the PK properties of SR7826 (compound 18b; 1mg/kg) with a Cl of 5.2 mL/min/kg, a T1/2 of 2.2h, an AUC of 8.4 μM*h and a Cmax of 7.7 μM, and has 36% oral bioavailability in rats (oral administration; 2mg/kg)[1].

Solvent & Solubility
DMSO : 100 mg/mL (258.11 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 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (6.45 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
