Target: Monopolar spindle 1 (Mps1)
IC50: 6.4 nM
TC 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].

TC Mps1 12, a novel Mps1 inhibitor, suppresses the growth of hepatocellular carcinoma cells via the accumulation of chromosomal instability.[Pubmed:28299790]
Br J Pharmacol. 2017 Jun;174(12):1810-1825.
BACKGROUND AND PURPOSE: Chromosomal instability is not only a hallmark of cancer but also an attractive therapeutic target. A diverse set of mitotic kinases maintains chromosomal stability. One of these is monopolar spindle 1 (Mps1, also known as TTK), which is essential for chromosome alignment and for the spindle assembly checkpoint (SAC). Pharmacological inhibition of Mps1 has been suggested as a cancer therapeutic; however, despite the existence of a novel Mps1 inhibitor, TC Mps1 12, no such studies have been performed. EXPERIMENTAL APPROACH: The effects of TC Mps1 12 on cell viability, chromosome alignment, centrosome number, mitotic duration, apoptosis and SAC were determined in hepatocellular carcinoma (HCC) cells. In addition, the association of Mps1 expression with the overall survival of HCC patients was analysed. KEY RESULTS: Treatment of human HCC cells with TC Mps1 12 led to chromosome misalignment and missegregation, and disorganization of centrosomes. Even in the presence of these errors, TC Mps1 12-treated cells overrode the SAC, resulting in a shortened mitotic duration and mitotic slippage. This mitotic catastrophe triggered apoptosis and, finally, inhibited the growth of HCC cells. In addition, the expression of the Mps1-encoding TTK gene was associated with poor overall survival of HCC patients. CONCLUSION AND IMPLICATIONS: TC Mps1 12 results in the accumulation of chromosomal instabilities and mitotic catastrophe in HCC cells. Overall, these data demonstrate that the inhibition of Mps1 kinase using TC Mps1 12 is a promising therapeutic approach for liver cancer.
Diaminopyridine-based potent and selective mps1 kinase inhibitors binding to an unusual flipped-Peptide conformation.[Pubmed:24900510]
ACS Med Chem Lett. 2012 Jun 6;3(7):560-4.
Monopolar spindle 1 (Mps1) is an attractive cancer drug target due to the important role that it plays in centrosome duplication, the spindle assembly checkpoint, and the maintenance of chromosomal stability. A design based on JNK inhibitors with an aminopyridine scaffold and subsequent modifications identified diaminopyridine 9 with an IC50 of 37 nM. The X-ray structure of 9 revealed that the Cys604 carbonyl group of the hinge region flips to form a hydrogen bond with the aniline NH group in 9. Further optimization of 9 led to 12 with improved cellular activity, suitable pharmacokinetic profiles, and good in vivo efficacy in the mouse A549 xenograft model. Moreover, 12 displayed excellent selectivity over 95 kinases, indicating the contribution of its unusual flipped-peptide conformation to its selectivity.
