Potent and selective monopolar spindle 1 (Mps1) kinase inhibitor (IC50 = 35 nM). Displays selectivity over 46 other kinases including Cdk1 and aurora kinase B. Interferes with chromosome alignment and overrides spindle assembly checkpoint. Inhibits the recruitment of Mad1, Mad2 and centromere protein E (CENP-E) to kinetochores.

Cell Cycle & DNA Damage Repair Poster
In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
