Assay: Fluorescence Polarization Assays: In another embodiment, Fluorescence Polarization ("FP") based assays may be used to detect and monitor ligand binding. Fluorescence polarization is a versatile laboratory technique for measuring equilibrium binding, nucleic acid hybridization, and enzymatic activity. Fluorescence polarization assays are homogeneous in that they do not require a separation step such as centrifugation, filtration, chromatography, precipitation, or electrophoresis. These assays are done in real time, directly in solution and do not require an immobilized phase. Polarization values can be measured repeatedly and after the addition of reagents since measuring the polarization is rapid and does not destroy the sample. Generally, this technique can be used to measure polarization values of fluorophores from low picomolar to micromolar levels.

Assay: Functional Assay: HEK293 cells were transfected with human TRPV1 cloned in pcDNA3.1zeo(+) using the Effectene non-liposomal lipid based transfection kit (Qiagen) (hTRPV1/HEK293). hTRPV1/HEK293 cells were routinely grown as monolayers under selection in zeocin (200 μg/mL; Invitrogen) in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, and penicillin/streptomycin (50 units/mL) in 5% CO2 at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl, 2 mM KCl, 2 mM MgCl2, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl2. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F127 (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca2+ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λexcitation=488 nm, λemission=540 nm) during challenge with agonist (capsaicin). The IC50 values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 Î¼M with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist.

Assay: Radioligand Binding Assay: HEK-293 cells stably expressing mouse TAAR1 were maintained at 37° C. and 5% CO2 in DMEM high glucose medium, containing fetal calf serum (10%, heat inactivated for 30 min at 56° C.), penicillin/streptomycin (1%), and 375 ug/ml geneticin (Gibco). Cells were released from culture flasks using trypsin/EDTA, harvested, washed twice with ice-cold PBS (without Ca2+ and Mg2+), pelleted at 1,000 rpm for 5 min at 4° C., frozen and stored at -80° C. Frozen pellets were suspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 10 mM EDTA and homogenized with a Polytron (PT 6000, Kinematica) at 14,000 rpm for 20 s. The homogenate was centrifuged at 48,000Ã¿g for 30 min at 4° C. Subsequently, the supernatant was removed and discarded, and the pellet resuspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 0.1 mM EDTA using the Polytron (20 s at 14,000 rpm). This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at -80° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 uM unlabeled ligand. All compounds were tested at a broad range of concentrations (10 pM to 10 uM) in duplicates. The test compounds (20 ul/well) were transferred into a 96 deep well plate (TreffLab), and 180 ul of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 ul of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3xKd in nM and 500 ul of the membranes (resuspended at 50 ug protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer. After addition of 45 ul of Microscint 40 (PerkinElmer) the Unifilter-96 plate was sealed and after 1 hr the ratioactivity counted using a TopCount Microplate Scintillation Counter (Packard Instrument Company).

Assay: Cell-Based Assay: Compounds were tested on human Nav1.7 (hNav1.7) expressed stably in 293 cells, which have no endogenous sodium channels. Two forms of whole-cell patch-clamp assays were used. In both, peak current through Nav1.7 was evoked by a depolarizing voltage pulse, and currents were monitored as a function of time in response to exposure to several different concentrations of drug. Automated electrophysiology uses the PatchXpress 7000A system. Up to sixteen cells at a time were voltage-clamped in parallel, and the steady-state voltage dependence of inactivation was determined experimentally for each cell. For each cell, fractional inactivation was set at 20%, and peak current through Nav1.7 as a function of time was measured in response to increasing concentrations of test compound. Manual electrophysiology refers to conventional whole-cell patch-clamping (Hamill et al., 1981). After formation of the whole-cell clamp, cells were lifted off the bottom of the dish with the patch pipette and positioned directly in front of an array of glass microperfusion tubes each with internal diameter about 250 microns, with individual compound concentrations flowing from each tube. Current as a function of time in response to increasing drug concentrations was measured with Nav1.7 fully in the resting state (holding voltage set to −140 mV) and on the same cells with the holding voltage set to produce about 20% inactivation. Compounds were not applied for a prespecified time, but for as long as required to achieve a stable level of block.

Assay: PIM Enzyme Assay: The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction.Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate.

Assay: ACC1 Enzyme Assay A1: For the assay, 50 nl of a 100-fold concentrated solution of the test substance in DMSO were pipetted into a black low-volume 384-well microtitre plate (Greiner Bio-One, Frickenhausen, Germany), 2 ul of a solution of ACC1 in assay buffer [50 mM HEPES/NaOH pH 7.5, 12 mM sodium bicarbonate, 2 mM MgCl2, 2 mM potassium citrate, 0.005% (w/v) bovine serum albumin (BSA)] were added and the mixture was incubated for 15 min to allow pre-binding of the substances to the enzyme prior to the enzyme reaction. The enzyme reaction was then started by addition of 3 ul of a solution of adenosine triphosphate (ATP, 83.5 uM=>the final concentration in 5 ul assay volume is 50 uM, Amersham Pharmacia Biotech #27-2056-01) and acetyl-CoA (33.4 uM=>the final concentration in 5 ul assay volume is 20 uM, Roche Bioscience #10101893001) in assay buffer, and the resulting mixture was incubated at 22° C. for a reaction time of 20 min. The concentration of the ACC1 was adjusted to the respective activity of the enzyme and set such that the assay was carried out in the linear range. Typical concentrations were in the range of 2.5 ng/ul. The reaction was stopped by successive addition of 2.5 ul of a solution of d2-labelled ADP (HTRF Transscreener ADP kit, C is biointernational, Marcoule, France) in EDTA-containing HTRF Transscreener ADP detection buffer (contained in the HTRF Transscreener ADP kit, 50 mM HEPES pH 7.0, 60 mM EDTA, 0.1% (w/v) BSA, 0.02% sodium azide, 400 mM potassium fluoride) and 2.5 ul of a solution of europium cryptate-labelled anti-ADP antibody (HTRF Transscreener ADP kit) in HTRF Transscreener ADP detection buffer. The resulting mixture was incubated at 22° C. for 1 h to allow binding of the europium cryptate-labelled anti-ADP antibody to the ADP formed by the enzyme reaction and the d2-labelled ADP.

Target: Calpain-1 catalytic subunit (SINGLE PROTEIN), Homo sapiens
UniProt: P07384
Assay: Inhibition FRET Assay: The Calbiochem InnoZyme activity kit was used for measuring the inhibition effect inhibitors on human erythrocyte calpain 1 activity. A calpain FRET substrate, (DABCYL)-TPLKSPPPSPR-(EDANS) (SEQ ID NO: 9), was used to detect the activity of Cal1. 20 μM of the FRET substrate, 10 nM of native Cal1, and 20 μM TCEP (reducing agent) were added to the reaction mixture containing assay buffer (Tris [10 mM], NaCl [100 mM], pH 7.4). Cal1 was activated by the addition of 10 μM calcium. Cleavage of the scissile bond amide bond, K-S, releases the fluorophore (EDANS) from the internal quenching molecule (DABCYL), resulting in an increase in fluorescence measured at 320 nm excitation and 480 nm emission wave lengths for 30 min. Each inhibitor was added to the reaction mixture at varying concentrations (10 nM, 100 nM, 1 μM, and 10 μM) to detect inhibition of Cal1 and reduction in fluorescence was measured by 96 well-plate reader.
