AT9283 is a potent inhibitor of several protein kinases, including Aurora A, Aurora B, Janus kinase 2 (JAK2), JAK3, and ABL. AT9283 potently inhibited proliferation and Jak2-related signalling in Jak2-dependent cell lines. The compound also demonstrated significant therapeutic potential in vivo in an ETV6-JAK2 (TEL-JAK2) murine leukaemia model.

| Cell lines | HCT 116 cells |
| Preparation method | Primary HCT116 Cellular Assay. HCT 116 cells were cultured in DMEM + 10% FBS + GLUTAMAX I. Black 96-well flat bottomed (clear) tissue culture treated plates were seeded at 5 × 103 cells per well in 200 µL of medium and incubated for approximately 16 h at 37 °C in a humidified atmosphere of 5% CO2 in air. Cells were treated with test compound at nine different concentrations (spanning 1 nM to 10 µM, plus DMSO vehicle control) and then incubated for 72 h. Polyploidy morphological observations of the cells were then noted. The concentration of test compound required to produce a distinct polyploid phenotype was reported. |

| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
