CHEMBL5737853

Kinase Inhibitory Activity Assay: The inhibitory activity on a C797S-containing epidermal growth factor receptor (EGFR) kinase and an MET kinase was measured for compound 1 obtained in the above Example, and the results are shown in Table 1 below. The kinase inhibitory activity was measured by the following method:1. Each kinase was incubated with 8 mM MOPS (pH 7.0), 0.2 mM EDTA, 250 μM KKKGQEEEYVFIE (SEQ ID NO: 1), 1 mM sodium orthovanadate, 5 mM sodium-6-glycerophosphate, 10 mM magnesium acetate, and [η-33P]-ATP.2. The compound to be evaluated (DMSO solution) and Mg/ATP were added to proceed the reaction.3. After about 40 minutes at room temperature, the reaction was stopped by the addition of 10 μL of 0.5% phosphoric acid.4. 10 μL of 0.5% reaction solution was spotted onto a P30 filtermat.5. Washed 4 times for about 4 minutes in 0.425% phosphoric acid. Washed once in methanol, and then dried and analyzed by scintillation counting to measure IC50 value.
