| Description: | Test substance: Compounds of the invention, prepared by the corresponding examples of the invention1. Experimental materials and instrumentsPDE9A2 Enzyme (BPS, Cat. No. 60090)384-well plate (Perkin Elmer, Cat. No. 6007279)2. Experimental procedurePreparation of the compounds: the compounds were prepared into 10 mM compound stock solution in DMSO for long-term storage. The obtained compound stock solution was diluted in 100 times with DMSO to obtain 100 μM compound working mother solution, and then the compound working mother solution was diluted in 3 times with DMSO to obtain 8-10 concentration gradients of diluted compound mother liquor (100×).Incubation with the compounds: A very small amount of liquid pipetting system Echo was used to pipette the diluted compound mother liquor into a 384-well plate. 200 nL diluted compound mother liquor and 10 μL PDE9A2 enzyme solution were added to each compound well. After centrifugation at 1000 rpm for 1 min, the mixture was incubated for 15 min at the room temperature. Then the 10 μL substrate mixture was added. After centrifugation at 1000 rpm for 1 min, the mixture was incubated with shocking for 30 min at the room temperature. Finally, a stop solution was added to end the reaction system. The mixture was incubated with shocking for 60 min at the room temperature. In the maximum reading hole (Max), the compound was replaced by solvent. In the minimum reading hole (Min), the compound and enzyme solution were replaced by solvent. |
