  • 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.

Biological Activity

Description Selinexor (KPT-330) is an orally bioavailable selective CRM1 inhibitor. Phase 2.
CRM1 [1]
(Cell-free assay)
In vitro

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. [1]

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. [1] 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. [2]


Cell Research:[1]
+ Expand
  • Cell lines: MOLT-4, Jurkat, HBP-ALL, KOPTK-1, SKW-3, and DND-41 cell lines
  • Concentrations: ~1 μM
  • Incubation Time: 72 hours
  • Method: Cell lines are cultured in RPMI 1640 medium, supplemented with 10% fetal bovine serum and penicillin/streptomycin. Cell Titer Glo assay is used to assess cell viability upon treatment with either dimethyl sulfoxide (DMSO) or KPT-330. Cells are plated at a density of 10 000 cells per well in a 96-well plate and incubated with DMSO or increasing concentrations of KPT-330. The cell viability is measured after 72 h exposure to KPT-330 and reported as a percentage of DMSO control cells. Jurkat cells that overexpress BCL2 are generated using MSCV-IRES-GFP retroviral expression system. Jurkat cells infected with BCL2 or control vector viruses are sorted by flow cytometry and the expression of BCL2 confirmed by Western blot analysis using BCL2 antibody.

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
