Assay Method Information

Assay Name:  Enzyme Assay
Description:  To check the B-Raf kinase inhibitory activity of the compounds of the present invention, the following experiments were conducted.(1) Serial Signaling: 20 ul of diluting solvent (20 mM MOPS, pH 7.2, 25 mM β-glycerol phosphate, 5 mM EGTA, 1 mM sodium orthovanadate, 1 mM dithiothreitol) and 10 ul of Mg/ATP mixed solution (500 uM ATP, 75 mM magnesium chloride) were added into a centrifuge tube, the derivative compound of Formula 1 was added or the compounds of the Examples were not added as a control group, and then 1 ng of activated B-Raf, 0.4 ng of inactivated MEK1, and 1 ug of inactivated MAPK2 were added. The solutions in the tube were collected on the bottom via centrifugation and were reacted at 30° C. for 30 minutes. After taking 4 ul of the mixed solution, the test proceeded to the next step.(2) Phosphorylation of Matrix Protein MBP by MAPK2: 10 ul of diluting solvent, 20 ug of MBP used as a matrix.
