Background
Target: Monopolar spindle 1 (Mps1)IC50: 6.4 nMTC Mps1 12 is a potent and selective monopolar spindle 1 (Mps1) inhibitor with IC50 value of 6.4 nM [1]. Monopolar spindle 1 (Mps1), also known as TTK, plays a critical role in the spindle assembly checkpoint, centrosome duplication, and the maintenance of chromosomal stability. Mps1 is highly expressed in cancer cells and activated during mitosis. Therefore, Mps1 is a promising anticancer drug target [1].In vitro: TC Mps1 12 displayed an excellent selectivity profile in a panel of 95 kinases, except for the Flt3 and Flt3 mutants (D835Y) [1]. TC Mps1 12 showed cellular inhibition of Mps1with an IC50 value of 131 nM in cell line that stably expresses FLAG-tagged Mps1. In addition, TC Mps1 12 inhibited the growth of A549 lung carcinoma cell lines with IC50 value of 0.84 μM [1].In vivo: TC Mps1 12 (25 mg/kg, oral administration) treatment showed good pharmacokinetic (PK) properties with a Cmax of 3542 ng/mL and AUC of 6604 ng h/mL in mice [1]. Moreover, TC Mps1 12 (25 to 100 mg/kg, oral administration) dose-dependently inhibited the tumor growth of A549 cells without body weight loss in the mouse A549 xenograft model [1].
