KPT-6566 (1-5 μM; 0-8 d) inhibits WT fibroblasts proliferation[1]. KPT-6566 (0-10 μM; 48 h) inhibits normal breast epithelial cells and cancer cells viability via a PIN1-dependent manner[1]. KPT-6566 (0-10 μM; 48 h) affects hyperphosphorylated pRB level, Cyclin D1 and PIN1 concentration[1]. KPT-6566 (2.5-5 μM; 48 h) inhibits the mut-p53, NOTCH1 and NRF2 pathways[1]. KPT-6566 (0-5 μM; 48 h) induces DNA damage via a PIN1-dependent way[1].

Solvent & Solubility
DMSO : 19.23 mg/mL (43.36 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 (protect from light, stored under nitrogen). 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 40% PEG300 5% Tween-80 45% Saline
Solubility: 1.92 mg/mL (4.33 mM); Suspended solution; Need ultrasonic
