P2X7 Radioligand Binding Assay: human or rat P2X7-1321N1 cells were collected and frozen @ −80° C. On the day of the experiment, cell membrane preparations were made according to standard published methods. The total assay volume was 100 μl:10 μl compound (10×)+(b) 40 μl tracer (2.5×)+50 μl membrane (2×). The tracer used for the assay was tritiated A-804598. The compound can be prepared as described in the literature. (Donnelly-Roberts, D. Neuropharmacology 2008, 56 (1), 223-229.) Compounds, tracer and membranes were incubated for 1 hour @ 4° C. The assay was terminated by filtration (GF/B filters pre-soaked with 0.3% PEI) and washed with washing buffer (Tris-HCl 50 mM). The IC50 generated in the binding assay was corrected for tracer concentration and affinity of the tracer to derive at the affinity (Ki) of the test compounds. The data are presented in Tables 1 and 2 under the headings: P2X7 human Ki (μM) and P2X7 rat Ki (μM). Data are analyzed and graphed on Graphpad Prism 5.
