Biological Activity
Description Aurora A Inhibitor I is a novel, potent, and selective inhibitor of Aurora A with IC50 of 3.4 nM.
Targets Aurora A Aurora B Aurora C
IC50 3.4 nM 3.4 μM [1] 0.432 μM [2]
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
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
Methods 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.
