Description

TAS-119 is a potent, selective and orally active Aurora A inhibitor with an IC50 of 1.0 nM. TAS-119 shows high selectivity for Aurora A over other protein kinases, including Aurora B (IC50 of 95 nM). TAS-119 has potent antitumor activites[1].

IC50 & Target[1]

Aurora A

1 nM (IC50)

Aurora B

95 nM (IC50)

In Vitro

TAS-119 enhances the antiproliferative effect of Paclitaxel in a variety of human cancer cell lines, including Paclitaxel-resistant cells[1].
TAS-119 (30-300 nM) dose dependently enhances cell growth inhibition by three taxanes (Paclitaxel, Docetaxel, and Cabazitaxel) in HeLa cells. TAS-119 induces mitotic accumulation predominantly in tumor cells, compared with that in normal diploid fibroblasts[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

TAS-119 (5-30 mg/kg; oral administration; twice daily on day 1 and everyday on day 2) treatment induces phosphorylated histone H3 (pHH3) in nude rats with the HeLa-luc xenografts[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Nude rats injected with HeLa-luc cells[1]
Dosage: 5 mg/kg, 10 mg/kg, and 30 mg/kg
Administration: Oral administration; twice daily on day 1 and everyday on day 2

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (4.11 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.08 mg/mL (4.11 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
