While MPS1-IN-1 is a relatively selective kinase inhibitor, it displays only moderate biochemical (~0.5 uM) and cellular (3-10 uM) potency. The original study does provide evidence of the engagement...

Cellular Use Rating
In Model Organisms
MPS1-IN-1 is only a moderately potent kinase inhibitor. In vitro IC50 = 350-650 nM for enzyme inhibition. Doses of 2-10 uM are required to inhibit MPS1-dependent activities in cells. The probe needs...

Cellular Use Rating
MPS1-IN-1 shows cellular activity in the range of 1-10 µM. Ideally the potency would be well below micromolar, but the compound is still useful for interrogating cellular biology. However, given the...
