CCT251455 is a potent and selective mitotic kinase monopolar spindle 1 (MPS1) inhibitor with an IC₅₀ of 3 nM.

IC50: 3 nM (MPS1)^[1]

CCT251455 is a highly potent inhibitor of MPS1 that demonstrates high selectivity versus kinases tested in a broad kinome profiling panel. CCT251455 inhibits P-MPS1 with an IC₅₀ of 0.04 μM in cell-based assay and has a GI₅₀ of 0.16 μM^[1].

Mice^[1]

^[1]Human HCT116 colon carcinoma cells are sc injected bilaterally in the flanks of female CrTac:NCr-Fox1(nu) athymic mice. Once tumors reach a mean diameter of 8 mm (day 15), mice are dosed twice at a 12 h intervals with 50, 75, or 100 mg/kg of CCT251455 in 10% (v/v) DMSO and 5% (v/v) Tween 20 in saline. Mice are culled (n=3 per group) at 2, 10, and 72 h after the second dose. Tumors are snap-frozen and stored at -80 °C until analysis^[1].
