Assay: Human alpha7 nAChR Binding Assay: The ability of compounds to displace binding of radioactive ligands from human α7 nAChR was determined, as a measure of the affinity of the compounds for these ligand-gated ion channels. The [125I]-αBungarotoxin competition binding assay was performed under contract by Cerep Poitiers, France following published the methods (Sharpies et al., J Neurosci. 2000; 20(8):2783-91). SH-SY5Y cells stably expressing human α7 nicotinic acetylcholine receptors, grown to confluency in 175 cm2 flasks, were washed briefly with warm PBS containing (in mm): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.) and scraped into cold phosphate buffer. Cells were washed by centrifugation for 3 min at 500×g and resuspended in 10 mL of ice-cold phosphate buffer. The suspension was homogenized for 10 sec using an Ultraturax and centrifuged for 30 min at 45,000×g. The pellet was resuspended in phosphate buffer (0.5 mL per original flask). SH-SY5Y membranes (30 μg protein) were incubated in a total volume of 2 mL in 50 mM phosphate buffer with 0.05 nM [125I]-αBgt and serial dilutions of test compound. Nonspecific binding was determined in the presence of α-bungarotoxin (1 μM). Samples were incubated for 120 min at 37° C. The reaction was terminated by filtration through Whatman GFA/E filter paper (presoaked overnight in 0.3% polyethyleneimine in PBS), using a Brandel Cell Harvester. Each condition was measured in duplicate. Filters were counted for radioactivity using a scintillation counter. The results were expressed as a percent inhibition of control specific binding obtained in the presence of the test compounds where Inhibition (%)=100−[(measured specific binding/control specific binding)×100].

SH-SY5Y cells stably expressing human α7 nicotinic acetylcholine receptors, grown to confluency in 175 cm2 flasks, were washed briefly with warm PBS containing (in mm): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.) and scraped into cold phosphate buffer. Cells were washed by centrifugation for 3 min at 500×g and resuspended in 10 mL of ice-cold phosphate buffer. The suspension was homogenized for 10 sec using an Ultraturax and centrifuged for 30 min at 45,000×g. The pellet was resuspended in phosphate buffer (0.5 mL per original flask). SH-SY5Y membranes (30 μg protein) were incubated in a total volume of 2 mL in 50 mM phosphate buffer with 0.05 nM [125I]-αBgt and serial dilutions of test compound. Nonspecific binding was determined in the presence of α-bungarotoxin (1 μM). Samples were incubated for 120 min at 37° C. The reaction was terminated by filtration through Whatman GFA/E filter paper (presoaked overnight in 0.3% polyethyleneimine in PBS), using a Brandel Cell Harvester. Each condition was measured in duplicate. Filters were counted for radioactivity using a scintillation counter. The results were expressed as a percent inhibition of control specific binding obtained in the presence of the test compounds where Inhibition (%)=100−[(measured specific binding/control specific binding)×100].
