Assay: Capsaicin-based Assay: One day prior to assay, TRPV1/CHO cells were seeded in 96-well clear-bottom black plates (20,000 cells/well) in growth media. On the day of the experiment, the cells were washed with 0.2 mL 1x Hank's Balanced Salt Solution (Life Technologies) containing 1.6 mM CaCl2 and 20 mM HEPES, pH 7.4 ("wash buffer"). Subsequently, the cells were loaded by incubation in 0.1 mL of wash buffer containing Fluo-4 at 3 uM final concentration. After 1 hour, the cells were washed twice with 0.2 mL wash buffer and resuspended in 0.1 mL wash buffer. The plates were then transferred to a Fluorescence Imaging Plate Reader (Molecular Devices). Fluorescence intensity was monitored for 15 seconds to establish a baseline. Subsequently, test compounds diluted in assay buffer (1x Hank's Balanced Salt Solution containing 1 mM CaCl2 and 20 mM HEPES, pH 7.4) containing 1% DMSO were added to the cell plate and fluorescence was monitored for 2 minutes. The final concentration of the compound was adjusted to range from 100 uM to 1.5625 uM. If the test compound was an especially potent antagonist, the final concentration of the compound was adjusted to range from 10 uM to 1.5625 nM. Human TRPV1 was then activated by the addition of 50 uL capsaicin (100 nM final concentration) and plates incubated for an additional 3 min.

Assay: FRET-Based Membrane Potential Assay: Two days prior to the experiment, frozen HEK293 cells stably expressing recombinant human Nav1.7 were quickly thawed and plated at 25,000 cells/well in growth medium [DMEM (Invitrogen #11965) with 10% HI FBS (Invitrogen #10082), 2 mM glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin (PSG, Sigma #G1146), and 500 ug/mL Geneticin (Invitrogen #10131)] in black-walled, clear-bottom 384-well poly-D-lysine-coated assay plates (Greiner Bio-One, Frickenhausen, Germany) and incubated in a humidified 5% CO2 incubator at 37° C. On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

Assay: In Vitro DGAT2 Assay: For determination of IC50 values, the reactions were carried out in 384-well white Polyplates (Perkin Elmer) in a total volume of 20 uL. To 1 uL of compounds dissolved in 100% DMSO and spotted at the bottom of each well, 5 uL of 0.04% bovine serum albumin (BSA) (fatty acid free, Sigma Aldrich) was added and the mixture was incubated at room temperature for 20 minutes. To this mixture, 10 uL of hDGAT2 membrane fraction (0.01 mg/mL) diluted in 100 mM Hepes-NaOH, pH 7.4, 20 mM MgCl2 containing 200 nM methyl arachidonyl fluorophosphonate (Cayman Chemical; dried from ethyl acetate stock solution under argon gas and dissolved in DMSO as 5 mM stock) was added. After this mixture was preincubated at room temperature for 2 hours, DGAT2 reactions were initiated by the addition of 4 uL of substrates containing 30 uM [1-14C]decanoyl-CoA (custom-synthesized by Perkin Elmer, 50 mCi/mmol) and 125 uM 1,2-didecanoyl-sn-glycerol (Avanti Polar Lipids) dissolved in 12.5% acetone. The reaction mixtures were incubated at room temperature for 40 min and the reactions were stopped by addition of 5 uL of 1% H3PO4. After the addition of 45 uL MicroScint-E (Perkin-Elmer), plates were sealed with Top Seal-A covers (Perkin-Elmer) and phase partitioning of substrates and products was achieved using a HT-91100 microplate orbital shaker (Big Bear Automation, Santa Clara, Calif.). Plates were centrifuged at 2,000×g for 1 min in an Allegra 6R Centrifuge (Beckman Coulter) and then were sealed again with fresh covers before reading in a 1450 Microbeta Wallac Trilux Scintillation Counter (Perkin Elmer). DGAT2 activity was measured by quantifying the generated product [14C]tridecanoylglycerol in the upper organic phase.

Assay: IMAP-FP Assay: Activated ERK2 activity was determined in an IMAP-FP assay (Molecular Devices). Using this assay format, the potency (IC50) of each compound was determined from a 10 point (1:3 serial dilution, 3 uM starting compound concentration) titration curve using the following outlined procedure. To each well of a black Corning 384-well plate (Corning Catalog #3575), 7.5 nL of compound (3333 fold dilution in final assay volume of 25 uL) was dispensed, followed by the addition of 15 uL of kinase buffer (tween containing kinase buffer, Molecular Devices) containing 0.0364 ng/mL (0.833 nM) of phosphorylated active hERK2 enzyme. Following a 15 minute compound & enzyme incubation, each reaction was initiated by the addition of 10 uL kinase buffer containing 2.45 uM ERK2 IMAP substrate peptides (2.25 uM-unlabeled IPTTPITTTYFFFK-COOH and 200 nM-labeled IPTTPITTTYFFFK-SFAM (5-carboxyfluorescein)-COOH), and 75 uM ATP.
