| | MEK1-Inhibiting Activity Assay |
| Description: | The MEK1-inhibiting activity of the compounds listed in Table 3 below were evaluated by the fluorescent polarization method as described below.The test compound, CRAF (Thermo Fisher Scientific Inc.), MEK1 (Thermo Fisher Scientific Inc.) and ERK2 (Carna Biosciences, Inc.) were mixed in ATP-containing buffer and reacted for 60 minutes at 30° C. FAM-labeled ERKtide (Molecular Devices Corp.) was then added and reaction was continued for 45 minutes at 30° C. IMAP (registered trademark) Progressive Binding Reagent (Molecular Devices Corp.) was further added, and reaction was continued for 15 minutes at room temperature. Following the reaction, the fluorescent polarization was measured with a fluorescent plate reader and the 50% inhibition concentration (IC50) was calculated based on the percent inhibition relative to a test compound-free control. |
