| Description: | To measure the DRAK1 and DRAK2 activity, the substrate MRCL3 peptide and ATP were mixed with the enzymes. After an appropriate period of time, the reaction product ADP was quantitatively analyzed. The buffer solution A was used to make a 3x substrate solution of 3x concentration so that the final concentrations of ATP and MRCL3 peptides were 1 uM, respectively, and 2.5 ul of each solution was dispensed into Optiplate 384 (perkin-elmer) microplate. The final concentrations of ATP and MRCL3 peptide were made to be 1 uM respectively by using buffer A, followed by preparing a 3x substrate solution. The prepared substrate solution was distributed in Optiplate 384 (Perkin-Elmer) microplate (2.5 ul/well). Then, the compounds of Examples 1~39 and the compounds of Comparative Examples 1-6, whose concentrations were tripled by the final concentration were distributed thereto (2.5 ul/well). Lastly, DRAK1 or DRAK2 enzyme solution, properly diluted by using buffer A, was added thereto (2.5 ul/well). Centrifugation was performed at 800 rpm for 1 minute, and then enzyme reaction was induced at 30 C. |
