Biological Activity

Description TAK-901 is a novel inhibitor of Aurora A/B with IC50 of 21 nM/15 nM. It is not a potent inhibitor of cellular JAK2, c-Src or Abl. Phase 1.

In vitro

TAK-901 inhibits Aurora A-TPX2 and Aurora B-INCENP in tight binding, time-dependent manner. Dissociation of TAK-901 from Aurora B-INCENP is slow with at 1/2 of 920 minutes, and the affinity constant for TAK-901 binding to Aurora B-INCENP is determined to be 0.02 nM. TAK-901 induces inhibition of cell proliferation in cultured human cancer cell lines from different tissues with IC50s ranging from 40 to 500nM. Consistent with Aurora B inhibition, TAK-901 treatment produces polyploidy in human PC3 prostate cancer and HL60 acute myeloid leukemia cells as measured by immunofluorescence and flow cytometry. Examination of a broad panel of kinases reveals that multiple kinases, including FLT3, FGFR and the Src family kinases, are inhibited by TAK-901 with IC50 values similar to those for Aurora A and B. In cells, TAK-901 suppresses the Flt3 and FGFR2 autophosphorylation with IC50 values close to that of Aurora B as measured by cellular histone H3 phosphorylation, whereas the IC50s for inhibition of cellular Src and Bcr Abl are 20-fold weaker. In a panel of pathway specific reporter-based cell models, TAK-901 inhibits the NFkB and JAK/STAT pathways with submicromolar potency. [1]


Solubility (25°C)

In vitro DMSO 101 mg/mL (200.14 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+2% 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 (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.
