Description: Functional Drug Screening System (FDSS): Calcium mobilization responses to KCl depolarization were evaluated by measuring the intensity of calcium-mediated fluorescent signal in the presence of BD Calcium Assay Dye (BD Biosciences, Franklin Lakes, N.J., U.S.A.), utilizing a Functional Drug Screening System (FDSS) by Hamamatsu Corporation (Bridgewater, N.J. U.S.A.).Twenty-four hr prior to assay, cells were seeded in clear-base poly-D-lysine-coated 384-well plates (BD Biosciences) at a density of 5,000 cells per well in culture medium and grown overnight in 5% CO2 at 37° C. On the day of assay, growth media were removed, and cells were loaded with BD calcium assay dye (BD Biosciences) for 35 min at 37° C. under 5% CO2 and then for 25 min at room temp. Utilizing the FDSS, cells were exposed to representative compounds of Formula (I) at varying concentrations, and intracellular calcium was measured for 5 min prior to the addition of 50 mM KCl for an additional 3 min of measurement.
