UniProt: Q15858
Assay: FLIPR Assay: In vitro assays were performed in a recombinant cell line expressing cDNA encoding the alpha subunit (Nav1.7, SCN9a, PN1, NE) of human Nav1.7 (Accession No. NM002977). The cell line was provided by investigators at Yale University (Cummins et al, J. Neurosci. 18(23): 9607-9619 (1998)). For dominant selection of the Nav1.7-expressing clones, the expression plasmid co-expressed the neomycin resistance gene. The cell line was constructed in the human embryonic kidney cell line, HEK293, under the influence of the CMV major late promoter, and stable clones were selected using limiting dilution cloning and antibiotic selection using the neomycin analogue, G418. Recombinant beta and gamma subunits were not introduced into this cell line. Additional cell lines expressing recombinant Nav1.7 cloned from other species can also be used, alone or in combination with various beta subunits, gamma subunits or chaperones.

Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens
UniProt: P49327
Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

Assay: Thallium Flux Assay: The ROMK channel functional thallium flux assay is performed in 384 wells, using the FLIPR-Tetra instrument. HEK-hKir1.1 cells are seeded in Poly-D-Lysine microplates and kept in a 37° C.-10% CO2 incubator overnight. On the day of the experiment, the growth media is replaced with the FluxOR™ reagent loading buffer and incubated, protected from light, at ambient temperature (23-25° C.) for 90 min. The loading buffer is replaced with assay buffer±test compound followed by 30 min incubation at ambient temperature, where the Thallium/Potassium stimulant is added to the microplate. The fluorescence intensity of wells containing 3 μM of a standard control ROMK inhibitor of the present invention is used to define the ROMK-sensitive component of thallium flux. Fluorescence in the presence of test compounds is normalized to control values to provide % fluorescence change. IC50 values represent the concentration of compound that inhibits 50% of the ROMK thallium flux signal.

Cells were cultured according to standard protocols (Freshney, 2000) in Dulbecco's Modified Eagle Medium with high glucose supplemented with 1 mM glutamine, 10% (vol/vol) heat-inactivated bovine calf serum, Penicillin/Streptomycin, 50 μg/ml hygromycin and 15 μg/ml blasticidin (all cell culture reagents and antibiotics from Invitrogen, Basel, Switzerland). bout 24 hrs before an experiment, 5×104 cells/well were seeded in poly-D-lysine coated, black/clear-bottomed 96-well plates. The cells were loaded with 2.5 μM Fluo-4AM in loading buffer (1×HBSS, 20 mM HEPES) for 1 hr at 37 °C. and washed five times with loading buffer. The cells were transferred into a Functional Drug Screening System 7000 (Hamamatsu, Paris, France), and 11 half logarithmic serial dilutions of test compound at 37 °C. were added and the cells were incubated for 10-30 min. with on-line recording of fluorescence. Following this pre-incubation step, the agonist L-glutamate was added to the cells at a concentration corresponding to EC20 (typically around 80 μM) with on-line recording of fluorescence; in order to account for day-to-day variations in the responsiveness of cells, the EC20 of glutamate was determined immediately ahead of each experiment by recording of a full dose-response curve of glutamate. Responses were measured as peak increase in fluorescence minus basal (i.e. fluorescence without addition of L-glutamate), normalized to the maximal stimulatory effect obtained with saturating concentrations of L-glutamate.

Target: Galactokinase (SINGLE PROTEIN), Homo sapiens
UniProt: P51570
Assay: qHTS Assay: Assay details and protocol: The primary assay monitored ATP depletion using Promega's KinaseGlo technology, where ATP levels are measured through luminescence generated from firefly luciferase, a bioluminescent ATP-dependent enzymes. ATP was held at 35 μM, near its reported KM value, and the KM for galactose was determined under the 1536-well assay conditions to be 50-100M (FIG. 1A). As well, the IC50 for a commercially available CD45 inhibitor (N-(9,10-dioxo-9,10-dihydrophenanthren-2-yl)pivalamide) was confirmed (previously found to inhibit GALK (FIG. 1B)). This was used as the positive control for the assay. The assay used 5 nM GALK and a 1 hr incubation time, which gave sufficient signal:background and stability for the HTS.
