CHEMBL5729995

Inhibition Assay: The inhibitory activity measurement against the kinases mentioned above was measured in the kinase inhibition reaction mixture containing 2 ul purified kinase protein (10-50 ng), 20 mM Tris-HCl, pH 8.0, 5 mM MgCl2, 0.5 mM dithiothreitol, 0.01 mM ATP, 4 ug of poly(D4Y)n peptide substrate (Promega), 0.2 uCi of 32P-ATP and the each compound shown in tablel. The mixture was incubated for 15 min at 30° C. and the reaction was then ended by adding a half volume of 30% phosphoric acid solution. Subsequently, the reaction mixture solution was spotted in avidin coated membrane (Promega). This membrane was washed using 50 mM phosphate, 0.1N NaCl buffer (pH 6.0) solution for 10 min 5 times and then the radioactivity of each spot was quantified by using a BAS image analyzer (Fuji).
