XMD8-87 is found to be potent in the inhibition of TNK2 phosphorylation. XMD8-87 and XMD16-5 potently inhibit phosphorylation of TNK2 truncation mutations found in solid tumor types.

| Cell lines | 293T cells |
| Preparation method | 293T cells expressing TNK2 are plated in 6-well format at a density of 250,000 cells per well 48 hours prior to treatment. Cells are then treated with a 100 μL of XMD8-87 or XMD16-5 at 5 μmol/L and with 9 1:1 serial dilutions down to ≈10 nmol/L. Two additional samples are treated with DMSO only. Cells are then incubated for 6 hours at 37°C. Protein extraction is accomplished by adding 300 μL of lysis buffer to cells after removing media. Plates are gently shaken for 5 minutes at room temperature. Lysates are collected and cleared of incompletely solubilized material by spinning for 10 minutes at maximum speed in a microcentrifuge. Samples are prepared for SDS-PAGE using the EPage loading buffer. |

| 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.
