| Description: | The biochemical reactions were performed at 32° C. in 384-well plates using a reaction volume of 41 μL and the following assay buffer conditions: 50 mM Tris pH 7.5, 100 mM NaCl, 20 mM MgCl2, 0.05% BSA, 0.01% Brij, 1 μM NADPH, and 250 μM α-KG. The IDH1 R132H enzyme was used in a final concentration of 1.5 nM. Test compounds were used in a concentration range between 0.002 and 10 μM. The final DMSO concentration was 2.4%.The reaction was incubated for 30 minutes, then 40 μL of detection mix (0.75 μg/ml Luciferase, 0.02 U/ml Oxidoreductase, 4 μg/mL FMN, 2 μL/ml decanal/ethanol, 50 mM Tris pH 7.5, 0.5% Glycerin, 0.01% Tween-20, 0.05% BSA) was added. Luminescence was measured on a luminescent reader (10 seconds measuring time, 1 second integration period, 30% sensitivity). The decrease in luminescence is proportional to mIDH1 activity. |
