ROCK2 19 nM (IC50) |

In Vitro
Ripasudil (K-115) is a potent inhibitor of ROCK, with IC50s of 19 and 51 nM for ROCK2 and ROCK1, respectively. Ripasudil also shows less potent inhibitory activities against CaMKIIα, PKACα and PKC, with IC50s of 370 nM, 2.1 μM and 27 μM, respectively[1]. Ripasudil (K-115; 1, 10 μM) induces cytoskeletal changes, including retraction and cell rounding and reduced actin bundles of cultured trabecular meshwork (TM) cells. Ripasudil (5 μM) sifnificantly reduces transendothelial electrical resistance (TEER), and increases FITC-dextran permeability in Schlemm’s canal endothelial (SCE) cell monolayers[2].

Ripasudil purchased from MedChemExpress. Usage Cited in: Mol Ther. 2023 Jun 7;31(6):1846-1856. [Abstract]
C57 mice were transplanted with luciferase-expressing hepatocytes. The effects of the ROCK inhibitor Ripasudil (17.3 mg/kg, i.p.), nonmuscle myosin II ATPase inhibitor Blebbistatin, β1-integrin agonist Pyrintegrin, and Src kinase inhibitor Dasatinib on hepatocyte liver engraftment were analyzed by bioluminescence imaging on days 3 and 5 after intrasplenic infusion.
Ripasudil purchased from MedChemExpress. Usage Cited in: Mol Ther. 2023 Jun 7;31(6):1846-1856. [Abstract]
Ripasudil (17.3 mg/kg, i.p.) treatment significantly decreased the colocalization between transplanted hepatocytes and Kupffer cells to 11.38% at 6 h and 14.49% at 12 h after transplantation.
Ripasudil purchased from MedChemExpress. Usage Cited in: Mol Ther. 2023 Jun 7;31(6):1846-1856. [Abstract]
Western blot assays showed rapid loss of CD59a protein on isolated hepatocytes, which could be blocked by Ripasudil (17.3 mg/kg, i.p.) treatment.

Solvent & Solubility
In Vitro:
H2O : ≥ 50 mg/mL (126.30 mM)
DMSO : 25 mg/mL (63.15 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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 (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (3.16 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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: ≥ 1.25 mg/mL (3.16 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
