Biological Activity
KPT-251 binds in the NES-binding groove, which is located on the central, convex side of the CRM1 ring[1].
KPT-251 (72 h) suppresses melanoma cell proliferation[2].
KPT-251 (1 μM; 0-48 h) modulates levels of p53, pRb, survivin, and ERK phosphorylation[2].
KPT-251 (0.1 and 1 μM; 0-72 h) induces cell-cycle arrest and apoptosis[2].

-
Cell Line:Mewo and A375 cells
-
Concentration:1 μM
-
Incubation Time:24, 48 and 72 h
-
Result:Reduced S-phase, both G1 and/or G2 cell-cycle arrest can be observed.
-
Cell Line:Mel-Juso, SK-MEL-28, SK-MEL-5 and A375 cells
-
Concentration:0.1 and 1 μM
-
Incubation Time:24, 48 and 72 h
-
Result:Increased caspase-3 and -7 activity in the tested melanoma cell lines in a dose- and time-related manner.
KPT-251 (50 mg/kg; p.o.; every other day for 21 days) suppresses tumor growth in mice melanoma xenograft models[2].

-
Animal Model:7-weekold female NOD-SCID-IL2Rcγnull (NSG) mice, introduced 2 × 106 luciferase-expressing MV4-11 cells via tail-vein injections[1]
-
Dosage:75 mg/kg/day
-
Administration:Gavage, three times per week for 5 weeks
-
Result:Exhibited significantly increased survival with leukemia progression occurring only after cessation of treatment, prevented infiltration of leukemia cells into mouse bone marrow and spleen, and spared normal hematopoietic cells.
-
Animal Model:Athymic nude mice Nu/Nu, melanoma xenograft models[2]
-
Dosage:50 mg/kg
-
Administration:Oral, every other day for 21 days
-
Result:Suppressed tumor growth, increased cleaved caspase-3 and decreased Ki67.

Storage
4°C, protect from light
* In solvent : -80°C, 6 months; -20°C, 1 month (protect from light)
Solvent & Solubility
DMSO : 100 mg/mL (266.50 mM; ultrasonic and warming and heat to 60°C; 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). 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 (6.66 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.
