Description

SR7826 is a class of bis-aryl urea derived potent, selective and orally active LIM kinase (LIMK) inhibitor with an IC50 of 43 nM for LIMK1. SR7826 is >100-fold more selective for LIMK1 than ROCK and JNK kinases[1].

IC50 & Target[1]

LIMK1

43 nM (IC50)

ROCKI

5536 nM (IC50)

ROCKII

6565 nM (IC50)

In Vitro

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].

In Vivo

SR7826 (10 mg/kg; oral gavage; once daily; for 11 days; hAPPJ20 mice) treatment significantly reduces the phosphorylation of cofilin at Ser3. SR7826 also increases both apical and basal thin spine density significantly in hAPPJ20 mice over mock-treated animals[2].
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].

In Vivo:

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.

  • Protocol 1

    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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (6.45 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
