BAY 1217389 (C09-0785-850)

InformationBAY 1217389 BAY 1217389 is an orally bioavailable, selective inhibitor of the serine/threonine kinase monopolar spindle 1 (Mps1) with IC50 values below 10 nmol/L while showing an excellent selectivity profile.TargetsMps1 (Cell-free assay) 0.63 nMIn vitroIn biochemical assays, the IC50 value of BAY 1217389 is 0.63±0.27 nmol/L. It shows high selectivity against other kinases and found to bind to PDGFRβ (<10 nmol/L), Kit (between 10 and 100 nmol/L), CLK1, CLK2, CLK4, JNK1, JNK2, JNK3, LATS1, MAK, MAPKAP2, MERTK, p38β, PDGFRα, PIP5K1C, PRKD1, and RPS6KA5 (between 100 and 1,000 nmol/L). In cellular mechanistic assays, BAY1217389 abrogats nocodazole-induced SAC activity and induced premature exit from mitosis ("mitotic breakthrough"), resulting in multinuclearity and tumor cell death. It is found to inhibit cell proliferation with a median IC50 of 6.7 nmol/L (range 3 to >300 nmol/L).In vivoBAY 1217389 achieves moderate efficacy in monotherapy in tumor xenograft studies. Its blood clearance is found to be low in the tested species. Vss is high and terminal half-lives were long. BAY 1217389 is administered orally to female NMRI mouse (1 mg/kg) and male Wistar rat (0.5 mg/kg). Peak plasma concentrations are observed between 1.5 and 7 hours. Oral bioavailability is high in rat and moderate in mouse.Cell Research(from reference)Cell lines：Tumor cell lines HeLa-MaTu and HeLa-MaTu-ADR cells Incubation Time：96 h.
