1 Customer Review
Bortezomib and KPT330 enhance apoptosis in HCT116 and RKO cells. A, HCT116 and RKO cells were treated with bortezomib, KPT330, or their combination for 48 hours at the indicated concentrations. The cells were subsequently stained with Annexin V, apoptotic cells were distinguished by flow cytometric analysis. B, Measurement of caspase-3 and -7 by means of a luminometric assay was performed in cells receiving the same treatment.

|Description||Selinexor (KPT-330) is an orally bioavailable selective CRM1 inhibitor. Phase 2.|
As the clinical candidate analog of KPT-185, KPT-330 exhibits similar effects on the viability of T-ALL cells and elicits rapid apoptotic response. KPT-330 also reduces cell growth in MOLT-4, Jurkat, HBP-ALL, KOPTK-1, SKW-3, and DND-41 cell lines, with IC50 values of 34-203 nM. 
|In vivo||KPT-330 dramatically suppresses the growth of T-ALL cells (MOLT-4) and AML cells (MV4–11) in vivo, with little toxicity to normal haematopoietic cells.  In SCID mice with diffuse human MM bone lesions, KPT-330 inhibits MM-induced bone lysis and prolongs survival. Moreover, KPT-330 directly impairs osteoclastogenesis and bone resorption by blocking RANKL-induced NF-κB and NFATc1, with minimal impact on osteoblasts and BMSCs. |
|In vitro||DMSO||88 mg/mL (198.5 mM)|
|Ethanol||40 mg/mL (90.23 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+49% PEG 300+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
