| Description: | Purified recombinant human FGFR4 protein was purchased from Carna Biosciences, Inc. When setting conditions for the measurement of the inhibitory effect of the compounds on FGFR4 kinase activity, a biotinylated peptide (biotin-EEPLYWSFPAKKK) was synthesized for use as a substrate by utilizing the amino acid sequence of FL-Peptide 22 (Caliper Life Sciences, Inc.) with biotin. The purified recombinant human FGFR4 protein used in the test was purchased from Carna Biosciences, Inc. In the measurement of the inhibitory effect of the compounds, first, a test compound was gradually diluted with dimethylsulfoxide (DMSO) to a concentration 20 times higher than the final concentration. Next, the purified human FGFR4 protein, substrate peptide (final concentration: 250 nM), magnesium chloride (final concentration: 5 mM), ATP (final concentration: 190 .mu.M), and the test compound DMSO solution (final concentration of DMSO: 5%) were added to a reaction buffer. |
