Introduction: The Aurora kinases play a key role in mitosis and have recently been identified as attractive targets for therapeutic intervention in cancer. The aim of this study was therefore to investigate the utility of 3'-[(18)F]fluoro-3'-deoxythymidine (FLT) and 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) for assessment of tumor response to the multi-targeted Aurora B kinase inhibitor, TAK-901.
Methods: Balb/c nude mice bearing HCT116 colorectal xenografts were treated with up to 30mg/kg TAK 901 or vehicle intravenously twice daily for two days on a weekly cycle.
