Kinase experiment: | The potency of the compound towards MPS1 and 60 additional kinases belonging to kinase selectivity screening (KSS) panel is determined using either a strong anion exchanger based assay or P81 Multiscreen plate. MPS1 activity is measured using 5 nM of MPS1 recombinant protein in 50 mM HEPES pH 7.5, 2.5 mM MgCl2, 1 mM MnCl2, 1 mM DTT, 3 μM NaVO3, 2 mM β-glycerophosphate, 0.2 mg/mL BSA, 200 μM P38-βtide substrate-peptide (KRQADEEMTGYVATRWYRAE) and 8 μM ATP with 1.5 nM 33P-γ-ATP. The assay is run in a robotized format, 10 serial 1:3 compounds dilutions (including NMS-P715, from 30 μM to 1.5 nM) are tested and IC50 determined[1]. |
Cell experiment: | Cells lines are seeded in 384 well-plates in the appropiate complete medium and treated with compounds (NMS-P715, etc.) dissolved in 0.1% DMSO 24 hours after seeding. The cells are incubated at 37°C and 5% CO2 and after 72 hours the plates are processed using CellTiter-Glo assay. Inhibitory activity is evaluated comparing treated versus control data using Assay Explorer software. IC50 of proliferation is calculated using sigmoidal interpolation curve fitting. Activity Ratio is calculated as the ratio of the single cell line IC50 and the IC50 average of all the cell lines tested[1]. |
Animal experiment: | Mice[1]Athymic nu-nu mice, 5-6 weeks of age (20-22 g) are used in the assay. A2780 ovary carcinoma and A375 melanoma cells are transplanted s.c. into female nu-nu mice. Mice bearing a palpable tumor (100-200 mm3) are selected and randomized into control and treated groups. Treatment starts one day after randomization. NMS-P715 is typically administered by oral administration at doses of 90-100 mg/kg daily for more than seven days. Each group includs 8 animals. Tumor dimension is measured regularly by calipers during the experiments and tumor mass is calculated[1]. |

NMS-P715 is an inhibitor of the spindle assembly checkpoint kinase Mps1/TTK (IC50 = 0.182 ?M).1 It is selective for Mps1/TTK over a panel of 59 additional kinases (IC50s = >5 ?M for all). NMS-P715 (1 ?M) accelerates mitosis, reducing the length of mitosis by approximately 3-fold, in U2OS cells. It induces aneuploidy and apoptosis in A2780 ovarian cancer cells when used at a concentration of 1 ?M, as well as inhibits proliferation in a panel of 127 cancer cell lines, including colon, breast, renal, and melanoma cells, with IC50 values ranging from 0.192 to 10 ?M. NMS-P715 (90 mg/kg per day) reduces tumor growth in an A2780 mouse xenograft model.

Multiple actions of NMS-P715, the monopolar spindle 1 (MPS1) mitotic checkpoint inhibitor in liver fluke-associated cholangiocarcinoma cells
Eur J Pharmacol 2022 May 5;922:174899.PMID:35337815DOI:10.1016/j.ejphar.2022.174899.
Aim: NMS-P715 is a potent inhibitor of monopolar spindle 1 (MPS1) mitotic checkpoint kinase. Overexpression of MPS1 is associated with short survival times in patients with cholangiocarcinoma (CCA). This study investigated the anti-cancer effects of NMS-P715 in human CCA cell lines. Main methods: KKU-100 and KKU-213A CCA cell lines were treated with NMS-P715 and cell viability was determined using MTT and colony formation assays. Inhibitory effects of NMS-P715 on cell cycle and apoptosis were evaluated using flow cytometry. Expression of underlying mechanism-related proteins was examined by Western blotting. Mitotic catastrophe was assessed by counting abnormal nuclei. Transwell assays were used to examine cell migration and invasion. Key findings: Molecular docking showed that the NMS-P715/MPS1 complex was driven by an induced-fit mechanism. We provide new evidence that NMS-P715 potently inhibited cell proliferation and colony formation in both CCA cell lines. This was accompanied by induction of G2/M arrest and the consequent induction of mitotic catastrophe, a process that occurs during defective mitosis. The recent study showed that NMS-P715 activated caspase-dependent apoptosis and autophagosome formation with an increase of LC3 A/B-II protein expression in CCA cell lines. NMS-P715 also greatly impeded cell migration and invasion in CCA cell lines. The combination of NMS-P715 and gemcitabine or cisplatin showed synergistic effects on CCA cell proliferation. Significance: This study revealed for the first time that NMS-P715 is a promising candidate for combating CCA owing via multiple actions and may be suitable for further development in a clinical study.
Selective inhibition of pancreatic ductal adenocarcinoma cell growth by the mitotic MPS1 kinase inhibitor NMS-P715
Mol Cancer Ther 2014 Feb;13(2):307-315.PMID:24282275DOI:10.1158/1535-7163.MCT-13-0324.
Most solid tumors, including pancreatic ductal adenocarcinoma (PDAC), exhibit structural and numerical chromosome instability (CIN). Although often implicated as a driver of tumor progression and drug resistance, CIN also reduces cell fitness and poses a vulnerability that can be exploited therapeutically. The spindle assembly checkpoint (SAC) ensures correct chromosome-microtubule attachment, thereby minimizing chromosome segregation errors. Many tumors exhibit upregulation of SAC components such as MPS1, which may help contain CIN within survivable limits. Prior studies showed that MPS1 inhibition with the small molecule NMS-P715 limits tumor growth in xenograft models. In cancer cell lines, NMS-P715 causes cell death associated with impaired SAC function and increased chromosome missegregation. Although normal cells appeared more resistant, effects on stem cells, which are the dose-limiting toxicity of most chemotherapeutics, were not examined. Elevated expression of 70 genes (CIN70), including MPS1, provides a surrogate measure of CIN and predicts poor patient survival in multiple tumor types. Our new findings show that the degree of CIN70 upregulation varies considerably among PDAC tumors, with higher CIN70 gene expression predictive of poor outcome. We identified a 25 gene subset (PDAC CIN25) whose overexpression was most strongly correlated with poor survival and included MPS1. In vitro, growth of human and murine PDAC cells is inhibited by NMS-P715 treatment, whereas adipose-derived human mesenchymal stem cells are relatively resistant and maintain chromosome stability upon exposure to NMS-P715. These studies suggest that NMS-P715 could have a favorable therapeutic index and warrant further investigation of MPS1 inhibition as a new PDAC treatment strategy.
Targeting the mitotic checkpoint for cancer therapy with NMS-P715, an inhibitor of MPS1 kinase
Cancer Res 2010 Dec 15;70(24):10255-64.PMID:21159646DOI:10.1158/0008-5472.CAN-10-2101.
MPS1 kinase is a key regulator of the spindle assembly checkpoint (SAC), a mitotic mechanism specifically required for proper chromosomal alignment and segregation. It has been found aberrantly overexpressed in a wide range of human tumors and is necessary for tumoral cell proliferation. Here we report the identification and characterization of NMS-P715, a selective and orally bioavailable MPS1 small-molecule inhibitor, which selectively reduces cancer cell proliferation, leaving normal cells almost unaffected. NMS-P715 accelerates mitosis and affects kinetochore components localization causing massive aneuploidy and cell death in a variety of tumoral cell lines and inhibits tumor growth in preclinical cancer models. Inhibiting the SAC could represent a promising new approach to selectively target cancer cells.
Understanding inhibitor resistance in Mps1 kinase through novel biophysical assays and structures
J Biol Chem 2017 Sep 1;292(35):14496-14504.PMID:28726638DOI:10.1074/jbc.M117.783555.
Monopolar spindle 1 (Mps1/TTK) is a protein kinase essential in mitotic checkpoint signaling, preventing anaphase until all chromosomes are properly attached to spindle microtubules. Mps1 has emerged as a potential target for cancer therapy, and a variety of compounds have been developed to inhibit its kinase activity. Mutations in the catalytic domain of Mps1 that give rise to inhibitor resistance, but retain catalytic activity and do not display cross-resistance to other Mps1 inhibitors, have been described. Here we characterize the interactions of two such mutants, Mps1 C604Y and C604W, which raise resistance to two closely related compounds, NMS-P715 and its derivative Cpd-5, but not to the well characterized Mps1 inhibitor, reversine. We show that estimates of the IC50 (employing a novel specific and efficient assay that utilizes a fluorescently labeled substrate) and the binding affinity (KD ) indicate that, in both mutants, Cpd-5 should be better tolerated than the closely related NMS-P715. To gain further insight, we determined the crystal structure of the Mps1 kinase mutants bound to Cpd-5 and NMS-P715 and compared the binding modes of Cpd-5, NMS-P715, and reversine. The difference in steric hindrance between Tyr/Trp604 and the trifluoromethoxy moiety of NMS-P715, the methoxy moiety of Cpd-5, and complete absence of such a group in reversine, account for differences we observe in vitro Our analysis enforces the notion that inhibitors targeting Mps1 drug-resistant mutations can emerge as a feasible intervention strategy based on existing scaffolds, if the clinical need arises.
Targeting MPS1 Enhances Radiosensitization of Human Glioblastoma by Modulating DNA Repair Proteins
Mol Cancer Res 2015 May;13(5):852-62.PMID:25722303DOI:10.1158/1541-7786.MCR-14-0462-T.
To ensure faithful chromosome segregation, cells use the spindle assembly checkpoint (SAC), which can be activated in aneuploid cancer cells. Targeting the components of SAC machinery required for the growth of aneuploid cells may offer a cancer cell-specific therapeutic approach. In this study, the effects of inhibiting Monopolar spindle 1, MPS1 (TTK), an essential SAC kinase, on the radiosensitization of glioblastoma (GBM) cells were analyzed. Clonogenic survival was used to determine the effects of the MPS1 inhibitor NMS-P715 on radiosensitivity in multiple model systems, including GBM cell lines, a normal astrocyte, and a normal fibroblast cell line. DNA double-strand breaks (DSB) were evaluated using γH2AX foci, and cell death was measured by mitotic catastrophe evaluation. Transcriptome analysis was performed via unbiased microarray expression profiling. Tumor xenografts grown from GBM cells were used in tumor growth delay studies. Inhibition of MPS1 activity resulted in reduced GBM cell proliferation. Furthermore, NMS-P715 enhanced the radiosensitivity of GBM cells by decreased repair of DSBs and induction of postradiation mitotic catastrophe. NMS-P715 in combination with fractionated doses of radiation significantly enhanced the tumor growth delay. Molecular profiling of MPS1-silenced GBM cells showed an altered expression of transcripts associated with DNA damage, repair, and replication, including the DNA-dependent protein kinase (PRKDC/DNAPK). Next, inhibition of MPS1 blocked two important DNA repair pathways. In conclusion, these results not only highlight a role for MPS1 kinase in DNA repair and as prognostic marker but also indicate it as a viable option in glioblastoma therapy. Implications: Inhibition of MPS1 kinase in combination with radiation represents a promising new approach for glioblastoma and for other cancer therapies.
