| | Inhibition of ALK WT Anaplastic Lymphoma Kinase Activity |
| Description: | The following experiment was performed in order to measure the activity of the N2-(2-methoxyphenyl)pyrimidine derivative represented by formula 1 of the present invention to inhibit anaplastic lymphoma kinase (ALK) activity at enzyme level. To measure the activity to inhibit ALK, each of the compounds prepared in examples listed in table 2 (2 μl) was loaded in a 384 well plate. Then, each of the compounds was mixed with anaplastic lymphoma kinase (ALK) enzyme (1 μl) and biotin conjugated peptide substrate (2 μl), followed by culture for 15 minutes. ATP solution (5 μl) was added thereto, followed by kinase reaction at room temperature for 30 minutes. Streptavidin conjugated XL 665 (5 μl) dissolved in ethylenediaminetetraacetic acid solution and europium (Eu3+) conjugated anti-phosphotyrosine antibody (5 μl) were added to the reaction solution to terminate the reaction. Upon completion of the reaction, one hour culture was performed, followed by analysis using homogeneous time-resolved fluorescence (HTRF, Cisbio). OD615/665 was measured with Wallac Envision 2103. IC50 of each compound was determined by using prism software (Version 5.01, Graphpad). |
