PT-262
Based on 1 Customer Validation
PT-262 is a potent ROCK inhibitor with an IC50 value of around 5 μM. PT-262 induces the loss of mitochondrial membrane potential and elevates the caspase-3 activation and apoptosis. PT-262 inhibits the ERK and CDC2 phosphorylation via a p53-independent pathway. PT-262 blocks cytoskeleton function and cell migration. PT-262 has anti-cancer activity.

PT-262 (5-40 μM; 24 h) induces cytotoxicity and proliferation inhibition in human lung cancer cells[1].
PT-262 (2-20 μM; 4-24 h) induces caspase-3 activation, mitochondrial dysfunction and apoptosis in lung cancer cells[1].
PT-262 (10-20 μM; 24 h) induces the accumulation of G2/M phases in both the p53-wild type and p53-null lung cancer cells, and inhibits the phosphorylation of CDC2 proteins[1].
PT-262 (0-10 μM; 24 h) represses ERK phosphorylation in lung cancer cells[1].
PT-262 (2 μM; 24 h) induces the cytoskeleton alteration and cell elongation in lung carcinoma A549 cells[2].
PT-262 (2-10 μM; 6 h) significantly blocks the cell migration in a concentration-dependent manner[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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (9.03 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
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.
