| | Enzyme activity inhibition IC50 evaluation experiment of Anaplastic Lymphoma Kinase ALK |
| Description: | Buffer preparation: 50 mM HEPES, pH 7.5, 0.00015% Brij-35.The compound was configured as a concentration gradient in 100% DMSO and added to a 384-well plate with a final DMSO concentration of 2%.1. ALK enzyme (purchased from Carna Biosciences, Inc.) was diluted to the optimum concentration with the following buffer: 50 mM HEPES, pH 7.5, 0.00015% Brij-35, 2 mM DTT, which was transferred to a 384-well plate and incubated with the compound for a certain time.2. The substrate was diluted to the optimum concentration with the following buffer: 50 mM HEPES, pH 7.5, 0.00015% Brij-35, mM MgCl2, adenosine triphosphate under Km, which was added to the 384-well plate to initiate the reaction and reacted at 28° C. for 1 hour.3. The conversion rate was read by Caliper Reader, the calculated inhibition rate is the average of the two tests.The compounds of the present invention were tested for the inhibitory activity of ALK according to the above test. |
