Biological Activity

Description LY2409881 is a potent and selective IKK2 inhibitor with IC50 of 30 nM, >10-fold selectivity over IKK1 and other common kinases.
IKK2 [1]
30 nM
In vitro

LY2409881 inhibits constitutively activated NF-ƘB, and causes concentration- and time-dependent growth inhibition and apoptosis in diffuse large B-cell lymphoma (DLBCL) cells. In the ovarian cancer cell line SKOV3, LY2409881 demonstrates moderate cytotoxicity. LY2409881 is synergistic with doxorubicin and cyclophosphamide in SUDHL2 cell in inhibiting the cell growth, but not in LY1 cell. In both SUDHL2 and LY1 cells, LY2409881 is synergistic with the histone deacetylase (HDAC) inhibitor romidepsin in inhibiting the cell growth.[1]

In vivo In SCID-beige xenograft mouse model, LY2409881 (50, 100, and 200 mg/kg, i.p.) significantly inhibits the tumor growth.[1]


Cell Research:[1]
- Collapse
  • Cell lines: OCI-LY10 cells
  • Concentrations: 25 μM
  • Incubation Time: ~72 h
  • Method: Cytotoxicity is evaluated using the CellTiter-Glo Reagent according to the manufacturer's manual. Experiments are carried out in 96-well plates, with each treatment in triplicate. Samples are taken at typically 24, 48, and 72 hours after treatment. Cytotoxicity is expressed by the decreasing percentage of live cells in each treatment relative to the untreated control from the same experiment. IC50 for each cell line is calculated using the CalcuSyn Version 2.0 software.

Solubility (25°C)

In vitro DMSO 20 mg/mL warmed (33.64 mM)
Water Insoluble
Ethanol Insoluble
In vivo Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+5% Tween 80+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.

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 (mg) = Concentration (mM) × Volume (mL) × 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.
