Background

Mps1-IN-2 is a potent and selective ATP-competitive inhibitor of Mps1 kinase with the IC50 value of 145nM [1].

Mps1-IN-2 has been reported to inhibit Mps1 kinase activity with the IC50 value of 145nM, when screened at 1μM ATP. In addition, Mps1-IN-2 has shown greater than 1000-fold selectivity to the Alk and Ltk enzyme. Moreover, Mps1-IN-2 has been revealed to bound to the ATP biding pocket of Mpa1 and formed a hydrogen bond with the hinge backbone (Glu603) at 2.74-? resolution. Mps1-IN-2 has been noted to abrogate SAC function and override the checkpoint through direct inhibition of Mps1[1].

Protocol

Kinase experiment:

The kinase binding assay is used to assess compound binding to TTK by monitoring displacement of a fluorescently labeled, ATP site-directed kinase inhibitor (Kinase Tracer 236) from the kinase active site. Each 15 μL assay contains 5 nM TTK, variable amounts of test compound (Mps1-IN-2), 30 nM Kinase Tracer 236, 2 nM Eu-anti-GST Antibody, and 1% DMSO (residual from compound dilution) in Kinase Buffer A (50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM EGTA, 0.01% Brij-35). Binding assays are initiated by addition of 5 μL of test compound (from 2-fold dilution series) to 5 μL of a kinase/antibody mixture, followed by addition of 5 μL of antibody. Assay plates are read using using standard Eu-based TR-FRET settings with excitation at 340 nm and emission monitored at 615 nm (donor) and 665 nm (acceptor). Emission intensities are measured over a 200 μs window following a 100 μs post-excitation delay[1].
