Radioligand Binding Assay: In the GR radioligand binding assay, test compounds were serially diluted in semi-log steps (10 concentrations) with a final concentration of 10 uM. Test compounds (1 uL) and controls (1 uL) in 100% DMSO were added to 96 Greiner V-bottom polypropylene plates. 0% control was 6.7% DMSO (final concentration in assay) and 100% control was 6.7 uM Dexamethasone.The full length GR was diluted to a final concentration of 3.3% (0.495 mg/ml) in assay buffer (20 mM Tris-HCl, 1 mM EDTA, 10% (w/v) Glycerol, 20 mM Sodium molbydate, pH 7.4). 45 uL of GR was added to each well and the plates were incubated for 15 min at room temperature.3H-dexamethasone solution was diluted to a concentration of 70 nM in assay buffer (7 nM final assay concentration) and 5 uL was added to each well. The samples were mixed for 5 min using a plate shaker at 700 rpm, before incubation for 2 h at room temperature,50 uL ice-cold charcoal solution.
