Assay: Radiometric Filter-Binding Assay: For determination of ABL kinase activity, the radiometric filter-binding assay was used. The assay was performed by mixing 10 μL of the compound pre-diluted with 10 μL of ATP (20 M ATP with 0.1 μCi [γ-33P]-ATP) with the phospho-acceptor peptide poly[Ala6Glu2LysHBr5Tyr1]=polyAEKY) in 20 mM Tris/HCl pH 7.5, 1 mM DTT, 10 mM MgCl2, 0.01 mM Na3VO4, 50 mM NaCl. 10 μL of enzyme (ranging between 5 nM to 20 nM) was added to initiate the reaction. Pre-incubation of enzyme with compounds (when stated) was performed by exposing the enzyme to compounds prior to addition of the substrate mixture (ATP and/or peptide substrate). After 15 min at room temperature, the reaction was stopped by the addition of 50 μL 125 mM EDTA, and the peptide-bound 33P separated on filter-plates (PVDF or MAIP; Millipore, Volketswil, Switzerland) prepared according to the manufacturer's instructions. Filter-plates were washed 3× with 0.5% H3PO4, followed by addition of 30 μL scintillation cocktail (Microscint, Perkin Elmer) per well and then analysed in a TopCount NXT scintillation counter (Perkin Elmer).

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: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.

Assay: Fluorescence Polarization (FP) Assay: Fluorescent polarization experiments were performed as follows. Briefly, the fluorescence polarization experiments were read on an Ultra Evolution 384-well plate reader (Tecan) with the 485 nm excitation and 535 nm emission filters. The fluorescence intensities parallel (Intparallel) and perpendicular (Intperpedicular) to the plane of excitation were measured in parallel perpendicular black 384-well NBS assay plates (Corning) at room temperature (20° C). The background fluorescence intensities of blank samples containing the references buffer were subtracted and steady-state fluorescence polarization was calculated using the equation: P=(Intparallel Gintperpendicular)/(Intparallel+Gintperpendicular), and the correction factor G (G=0.998 determined empirically) was introduced to eliminate differences in the transmission of vertically and horizontally polarized light. All fluorescence polarization values were expressed in millipolarization units (mP).

Assay: B-RAF (V600E) Kinase Assay: In a dilution series 10 uL/well of test substance solution are placed in a multiwell plate. The dilution series is selected so that generally a range of concentrations of 2 uM to 0.119 nM or 0.017 nM is covered. If necessary the initial concentration of 2 uM is changed to 50 uM, 10 uM or 0.4 uM or 0.2857 uM and further dilution is carried out accordingly. The final concentration of DMSO is 5%. 10 uL/well of the B-Raf (V600E)-kinase solution are pipetted in (containing 0.5 ng B-Raf (V600E)-kinase (e.g. from Upstate) in 20 mM Tris-HCl pH 7.5, 0.1 mM EDTA, 0.1 mM EGTA, 0.286 mM sodium orthovanadate, 10% glycerol, 1 mg/mL bovine serum albumin, 1 mM dithiothreitol) and the mixture is incubated for 1 h at RT under with shaking. The kinase reaction is started by the addition of 20 uL/well ATP solution [final concentration: 250 uM ATP, 30 mM Tris-HCl pH 7.5, 0.02% Brij, 0.2 mM sodium orthovanadate, 10 mM magnesium acetate, 0.1 mM EGTA, phosphatase cocktail (Sigma, #P2850, dilution recommended by the manufacturer)] and 10 uL/well MEK1 solution [containing 50 ng biotinylated MEK1 (prepared from purified MEK1 according to standard procedure, e.g. with EZ-Link Sulpho-NHS-LC-Biotin reagent, Pierce, #21335)] and carried out for 60 min at RT with constant shaking. The reaction is stopped by the addition of 12 uL/well of a 100 mM EDTA solution and incubation is continued for a further 5 min. 55 uL/well of the reaction solution are transferred into a streptavidin-coated plate (e.g. Streptawell HighBond, Roche, #11989685001) and shaken gently for 1 h at RT, in order to bind biotinylated MEK1 to the plate.

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: Inhibition Assay: The factor XIa inhibition of the inventive substances is determined using a biochemical test system which utilizes the reaction of a peptidic factor XIa substrate to determine the enzymatic activity of human factor XIa. Here, factor XIa cleaves from the peptic factor XIa substrate the C-terminal aminomethylcoumarin (AMC), the fluorescence of which is measured. The determinations are carried out in microtitre plates.Test substances are dissolved in dimethyl sulphoxide and serially diluted in dimethyl sulphoxide (3000 uM to 0.0078 uM; resulting final concentrations in the test: 50 uM to 0.00013 uM). In each case 1 ul of the diluted substance solutions is placed into the wells of white microtitre plates from Greiner (384 wells). 20 ul of assay buffer (50 mM of Tris/HCl pH 7.4; 100 mM of sodium chloride solution; 5 mM of calcium chloride solution; 0.1% of bovine serum albumin) and 20 ul of factor XIa from Kordia (0.45 nM in assay buffer) are then added successively. After 15 min of incubation, the enzyme reaction is started by addition of 20 ul of the factor XIa substrate Boc-Glu(OBzl)-Ala-Arg-AMC dissolved in assay buffer (10 uM in assay buffer) from Bachem, the mixture is incubated at room temperature (22° C.) for 30 min and fluorescence is then measured (excitation: 360 nm, emission: 460 nm). The measured emissions of the test batches with test substance are compared to those of control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide), and IC50 values are calculated from the concentration/activity relationships.

Using the cAMP-Nano-TRF detection kit the assay (Roche Diagnostics) was stopped by the addition of 50 μl lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN3) and 50 μl detection solutions (20 μM mAb Alexa700-cAMP 1:1, and 48 μM Ruthenium-2-AHA-cAMP) and shaken for 2 h at room temperature. The time-resolved energy transfer is measured by a TRF reader (Evotec Technologies GmbH), equipped with a ND:YAG laser as excitation source. The plate is measured twice with the excitation at 355 nm and at the emission with a delay of 100 ns and a gate of 100 ns, total exposure time 10 s at 730 (bandwidth 30 nm) or 645 nm (bandwidth 75 nm), respectively. The FRET signal is calculated as follows: FRET=T730-Alexa730-P(T645-B645) with P=Ru730-B730/Ru645-B645, where T730 is the test well measured at 730 nM, T645 is the test well measured at 645 nm, B730 and B645 are the buffer controls at 730 nm and 645 nm, respectively. cAMP content is determined from the function of a standard curve spanning from 10 μM to 0.13 nM cAMP.

Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens

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.
