NMS-P715 is a potent and selective inhibitor of MPS1 kinase with IC50 value of 8 nM .
Human monopolar spindle 1 (MPS1) kinase is a serine/threonine kinase that plays an important role in spindle assembly checkpoint (SAC) signaling by influencing the stability of the kinetochore-microtubule interaction and controlling chromosome alignment .
NMS-P715 is an orally available, selective and ATP-competitive MPS1 kinase inhibitor. In nocodazole-arrested U2OS cells, NMS-P715 promoted massive SAC override with EC50 value of
65 nM. In U2OS cells overexpressing YFP-α-tubulin, NMS-P715 induced mitotic acceleration and reduced mitotic cells. In nocodazole-arrested HeLa cells with MG132, NMS-P715 leads to complete delocalization of MAD1, MAD2, BUB1, BUB3 and Borealin and also reduced MPS1. In A2780 ovarian cancer cells, NMS-P715 reduced G1 phase, caused a flattening in G2/M phase of the cell cycle and subsequently induced apoptosis . In human and murine pancreatic ductal adenocarcinoma (PDAC) cells, NMS-P715 inhibited cell growth . In glioblastoma (GBM) cells, NMS-P715 increased the radiosensitivity of GBM cells by induction of post-radiation mitotic catastrophe and reduced repair of DNA double strand breaks (DSBs) .
In nude mice bearing human A2780 ovary carcinoma xenograft model, NMS-P715 (90 mg/kg for 7 days) inhibited tumor growth by 53%. In the A375 melanoma xenograft model, NMS-P715 (100 mg/kg for 10 days) inhibited tumor growth by 43% .
