    • 33P-MeSADP, and serial dilutions of test compounds, vehicle or 300 nM 2-MeSADP for the definition of non-specific binding. Dry compounds were prepared as 10 mM DMSO stocks and were diluted in seven-point, threefold dilution series in assay buffer with 0.02% BSA. Each concentration was run in triplicate beginning at 10 mM, final concentration in the assay. Binding reactions were incubated at room temperature for 1 h and stopped by dilution and transfer/aspiration of the mixture onto GF/B UniFilter 96 Well Plates (Perkin-Elmer), and washed 3× with ice-cold 50 mM Tris, pH 7.4. The filter plates were counted on a Top Count (Perkin-Elmer) and data were analyzed using GraphPad Prism using a single site binding equation.

    • note
    • Compounds were examined at a single concentration (3 μM) and conducted in duplicate using a minimum of one positive control inhibitor per CYP-specific assay which included CYP1A2, CYP2C9, CYP2D6, and CYP3A4. Incubation time for the assays were 30 min at 37 °C and end-point measurements were used to assess the degree of inhibition. These compounds can be categorized as weak inhibitors with percent inhibition values of <25%.

    • Compounds were examined at a single concentration (10 μM) in a 384 well fluorescence polarization assay using Cy3B tagged N-desmethyl dofetilide to competitively bind to HEK-hERG membrane homogenates. Incubation time for the assay was 120 min and end-point measurements were used to assess the degree of inhibition. These compounds can be categorized as weak inhibitors with percent inhibition values of <25%.
