Abstract: Medical uses and methods are provided for treating cancer using monopolar spindle 1 (MPS1) kinase inhibitors. Methods and uses for selecting MPS1 kinase inhibitors for use in treating cancer in a subject are provided, both in the initial selection of MPS1 kinase inhibitors and for addressing the development of acquired drug resistance that occur in the course of treatment.

Abstract: The present invention provides compounds of formula (I) and pharmaceutically acceptable salts, hydrates and solvates thereof for use in the treatment of cancer:

Abstract: The present invention relates to compounds of formula I: wherein R1 and R2 are as defined herein, or a pharmaceutically acceptable salt or solvate thereof. The compounds of formula I are inhibitors of aurora kinase and/or FLT3. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which aurora kinase and/or FLT3 activity is implicated.
