Assay: Nav 1.7 In Vitro Patch Express (PX) Assay: HEK 293 cells stably transfected with human Nav1.7 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system (Molecular Devices, LLC, Sunnyvale, Calif.). Compound effects were measured on a partially inactivated state of the sodium channel. Cells were clamped to a holding potential yielding 20 to 50% inactivation. To elicit sodium current, channels were activated by pulsing to −10 mV for 20 msec. This voltage protocol was repeated at a rate of 0.1 Hz throughout the experiment. A single concentration of test compound was applied to cells for a duration of 3 minutes. Peak sodium current was measured at the end of the compound addition period to determine percent inhibition. Three to five cells were tested per concentration, and IC50 curves were fitted to percent inhibition as a function of concentration.

Assay: Nav 1.5 In Vitro PX Assay: 293 cells stably transfected with human Nav 1.5 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system according the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Cells were held at a holding potential of −50 mV to inactivate sodium channels. To elicit sodium currents the voltage was changed to −120 mV to recover a portion of the channels, followed by delivery of test pulses of 20 msec duration to 0 mV, at 0.1 Hz. A single concentration of test compound was applied to cells for a duration of 5 minutes. Peak sodium current was measured at the end of the compound addition period to determine percent inhibition. A minimum of two cells were tested per concentration.

A 16-point, half-log dilution series of compounds at 41x final concentration is used for generating IC50 curves. Compound dilution series are prepared in 100% DMSO. ERK2 is preincubated with compounds for 30 minutes at ambient temperature. Reaction is initiated by addition of a substrate cocktail of ERKtide peptide and ATP and is allowed to proceed for 2-3 hours at ambient temperature. Reaction is terminated by addition of 10 uL of a 2x stop buffer consisting of 100 mM Tris-Cl [pH 7.5], 25 mM EDTA, 0.01% Tween 20, 10 ug/mL of AlphaScreen Protein A Acceptor Beads, 10 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1.4 ug/mL phospho-EGF Receptor (Thr669) antibody (Cat #3056, Cell Signaling Technology, Danvers, Mass.).

Assay: FRET-Based Assay: The HCV NS3 protease functions have been extensively studied and are considered as potential targets for antiviral therapy: see for example the many references listed in the introductory section of this application. Therefore, the activity of the compounds of the invention as anti-HCV agents was assessed using a full length HCV NS3 protease.The protease activity of the full length NS3/4a was measured using a FRET-based assay utilizing a peptide substrate derived from the NS4A/B cleavage site (Anaspec) and labelled at one end with a quencher (QXL520) and at the other with a fluorophore (5-FAMsp). NS3/4a (produced in-house by literature methods) was incubated with test compounds and peptide substrate in 50 mM Tris pH8, 20 mM DTT, 1% CHAPS, 10% glycerol and 5% DMSO. The reaction was followed by monitoring the change in fluorescence on a Molecular Devices Gemini plate reader for 30 minutes at room temperature.

Assay: Fluorescence Biochemical Assay: The IDH1 (R132H) mutant catalyzes the reduced form of NADP+ (NADPH) and α-ketoglutarate (α-KG) to form nicotinamide adenine dinucleotide phosphate (NADP+) and R (−)-2-hydroxyglutarate (2HG). The reaction can be monitored kinetically by following the oxidation of NADPH to NADP+ which is measured using fluorescence, excitation at 355 nm and emission at 530 nm. Reactions were monitored using the Perkin-Elmer Envision, Model 2101. More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Cat. No. 781076) using a final reaction volume of 20 μL and the following assay buffer conditions: 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM DTT, 0.02% BSA, 0.02% Tween-20, 10 μM NADPH and 100 μM α-KG. The final reaction mixture contained 2.5% DMSO and test compounds with concentrations ranging 0.0000008-25 μM. The IDH1 (R132H) enzyme was used at a final concentration of 10 nM.

Assay: PDE10 Fluorescence Polarization (FP) Assay: The fluorescence polarization assay for cyclic nucleotide phosphodiesterases was performed using an IMAP FP kit supplied by Molecular Devices, Sunnyvale, Calif. (product # R8139). IMAPU technology has been applied previously to phosphodiesterase assays (Huang, W., et al., J. Biomol Screen, 2002, 7: 215). Assays were performed at room temperature in 384-well microtiter plates with an incubation volume of 20.2 uL. Solutions of test compounds were prepared in DMSO and serially diluted with DMSO to yield 8 uL of each of 10 solutions differing by 3-fold in concentration, at 32 serial dilutions per plate.

Assay: [35S]GTPgammaS Binding Assay: The frozen cell membrane fraction prepared as described above was thawed before use, and the resultant was diluted with a buffer for a binding assay (final concentrations: 20 mM HEPES, 100 mM NaCl, 1 mM MgCl2, 3 uM GDP, 300 ug/mL saponin, 0.1% BSA). The compound of each example was added to a cell membrane fraction containing 1.8 to 3 ug/assay of membrane protein on a plate, followed by incubation at room temperature for 30 minutes. Thereafter, with glutamic acid (in a final concentration of 10 uM) added thereto, incubation was performed at room temperature for 15 minutes, and thereafter, [35S]GTPγS (in a final concentration of 0.8 kBq) and 588 ug WGA-SPA beads were added thereto, followed by incubation at room temperature for 1 hour. After the incubation, the plate was subjected to the centrifugal separation at 2,500 rpm and room temperature, and then, membrane cell binding radioactivity was measured with a top count. A [35S]GTPγS binding amount obtained in the presence of glutamic acid was defined as specific binding. On the basis of ratios of inhibiting the specific binding at various concentrations of the compounds of the respective examples, inhibition curves were obtained. Concentrations of the compounds of the respective examples at which the specific [35S]GTPγS binding amount was suppressed by 50% (IC50 values) were calculated on the basis of the inhibition curves.

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. The final reaction in each well of 25 uL consists of 0.5 nM hERK2, 900 nM unlabeled peptide, 80 nM labeled-peptide, and 30 uM ATP.
