| Description: | HEK293-A2AR-luc2p/CRE/Hygro cells were seeded at a density of 5,000 cells/well in DMEM with 1% FBS and 1 U/mL adenosine deaminase (ADA) (Sigma). After 18 h, the cells were treated with 3 nM CGS21680 plus a series dilution of A2AR antagonist, the compounds disclosed herein at the concentration of 0.1 10000 nM, prepared in DMEM with 1% FBS. After 5 h incubation, the luciferase activity in cells were measured using the Bright-Glo Luciferase Assay System (Promega) according to manufacturer's instructions. The luminescence signal was measured using a PHERAstar FS plate reader (BMG Labtech). Luminescence intensity from 10 μM preladenant treatment was set as 0%. Maximal luminescence intensity was determined in the presence of 3 nM CGS21680 and was set as 100%. The IC50 value was calculated from a dose dependent inhibition curve across the range of compound concentrations. |
