1.25mg/ml Taking the 1 mL working solution as an example, add 50 μL 25 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description TCS7010 (Aurora A Inhibitor I) is a novel, potent, and selective inhibitor of Aurora A with IC50 of 3.4 nM in a cell-free assay. It is 1000-fold more selective for Aurora A than Aurora B. Aurora A Inhibitor I (TC-S 7010) triggers apoptosis through the ROS-mediated UPR signaling pathway.
Targets
Aurora A [1]
(Cell-free assay)
3.4 nM
In vitro

Aurora A Inhibitor I is a 2,4-dianilinopyrimidine that selectively and potently inhibits Aurora A. Aurora A Inhibitor I effectively inhibits the proliferation of HCT116 and HT29 cells, with IC50 of 190 nM and 2.9 μM, respectively. The Aurora A selectivity of Aurora A Inhibitor I against Aurora B depends on a single amino acid (Thr217) of Aurora A. [1] In KCL-22 cells, Aurora A Inhibitor I (1-5 μM) increases G2/M cell fraction, induces histone H3 serine 10 phosphorylation, and suppresses mitotic Aurora A autophosphorylation on Thr288. Aurora A Inhibitor I (0.5-5 μM) also suppresses cell proliferation in KCL-22 cells, as well as BCR-ABL-negative leukemia cell lines KG-1 and HL-60. Aurora A Inhibitor I effectively induces apoptosis in KCL-22 cells at 5 μM. [2] In a recent study, Aurora A Inhibitor I is also found to inhibit cell growth of HCT116, HT29, and HeLa cells, with IC50 of 377.6 nM, 5.6 μM, and 416 nM. [3]
Features Aurora A Inhibitor I is a novel, potent, and selective inhibitor to Aurora A.

Protocol (from reference)

Kinase Assay:

[1]
  • Auroras A and B Inhibition Assays

    Both Auroras A and B are assayed in ELISA format using a GST fusion (pGEX-4T) of the N-terminus of Histone H3 (aa 1−18) as substrate. Plates are coated with 2 μg/mL substrate in PBS then blocked with 1 mg/mL I-block in PBS. Kinase reactions are run for 40 min with 5 ng/mL (0.16 nM) Aurora A or 45 ng/mL (1.1 nM) Aurora B at 30 μM ATP (~ Km) in kinase buffer. Final DMSO concentration is 4%. Product is detected by incubation with antiphosphohistone H3 (Ser10) 6G3 mouse monoclonal antibody and sheep-anti-mouse HRP conjugate, followed by washing and addition of TMB substrate. After quenching with 1 M phosphoric acid, plates are read at 450 nM.
Cell Assay:

[1]
  • Cell lines

    HCT116 and HT29 cells

  • Concentrations

    0.1 nM - 10 μM, dissolved in medium lacking serum and glutamine (dissolved in DMSO as stock solution)

  • Incubation Time

    72 hours

  • Method

    Cells are seeded in 384-well plates on day 0 in 50 μL of complete medium and incubated overnight in a 5% CO2 atmosphere at 37 °C. On day 1, 10 μL of Aurora A Inhibitor I is added. On day 4, plates are allowed to reach room temperature, and 30 μL Cell Titer-Glo reagent is added to each well to measure total ATP levels. Plates are read after shaking 15 min at room temperature.
Animal Study:

[5]
  • Animal Models

    BALB/c nude mice bearing ARID1A isogenic tumors

  • Dosages

    30 and 60 mg/kg

  • Administration
