| Hazard Information | Back Directory | [Description]
MPI-0479605 is a potent and ATP-competitive inhibitor of the mitotic kinase MPS1 (IC50 = 1.8 nM). It is selective for MPS1 over a panel of 79 kinases at a concentration of 500 nM. MPI-0479605 induces time-dependent degradation of cyclin B and securin and decreases phosphorylation of BUBR1 resulting in failed cytokinesis in HeLa cells arrested by nocodazole . It also causes misalignment of chromosomes at the anaphase plate and aneuploidy in A549 cells and slows cell cycle progression of HCT116 and COLO 205 cells irrespective of p53 activity. MPI-0479605 (30-150 mg/kg) reduces tumor volume in an HCT116 mouse colon cancer xenograft model in a dose-dependent manner. | [Uses]
MPI-0479605 is a potent and selective ATP-competitive inhibitor of Mps1, with an IC50 of 1.8 nM. | [in vivo]
MPI-0479605 (30 mg/kg daily or 150 mg/kg every fourth day (Q4D), i.p.) inhibits tumor growth by 49% and 74 % in HCT-116 xenografts. However, MPI-0479605 does not show inhibitory activity via daily dosing on the Colo-205 xenografts, and dosing every four days causes 63% tumor growth inhibition (TGI)[1]. | [IC 50]
