Assay: Inhibition Assay: The IC50 values for the PHD2 enzyme (residues 181-417) were determined by mixing increasing amounts of inhibitor with a fixed amount of enzyme (5 nM, final concentration) and Biotin labeled peptide (Biotin-Asp-Leu-Glu-Met-Leu-Ala-Pro-Tyr-Ile-Pro-Met-Asp-Asp-Asp-Phe-Gln-Leu, 1 uM final concentration) and 2-Oxyglutarate (2 uM final concentration) in 50 mM HEPES, 50 mM KCl, 0.5 mM TCEP, 2 uM FeCl2, 0.1 mg/ml BSA, at pH 7.3. The reaction was conducted by pre-incubating the enzyme in the presence of inhibitor for 60 min at room temperature. The activity of the free enzyme was measured by adding the peptide, the 2-Oxoglutarate (see above for final concentrations), and Ascorbic Acid (1 mM final concentration). The enzymatic activity was quenched after 60 min by adding an excess of a tight binding inhibitor to the assay mixture. The amount of product released was measured by using a LC/MS system (Agilent HPLC with Applied Biosystems API3000 Mass Spectrometer).

Target: Rho-associated protein kinase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O75116
Assay: In Vitro Assay: The effectiveness of compounds of the present invention as ROCK inhibitors can be determined in a 30 μL assay containing 20 mM HEPES, pH 7.5, 20 mM MgCl2, 0.015% Brij-35, 4 mM DTT, 5 μM ATP and 1.5 μM peptide substrate (FITC-AHA-AKRRRLSSLRA-OH). Compounds were dissolved in DMSO so that the final concentration of DMSO was <2%, and the reaction was initiated with Rho kinase variants. After incubation, the reaction was terminated by the addition of EDTA and the phosphorylated and non-phosphorylated peptides separated using a LABCHIP® 3000 Reader (Caliper Life Sciences). Controls consisted of assays that did not contain compound, and backgrounds consisted of assays that contained enzyme and substrate but had EDTA from the beginning of the reaction to inhibit kinase activity. Compounds were tested in dose-response format, and the inhibition of kinase activity was calculated at each concentration of compound. The inhibition data were fit using a curve-fitting program to determine the IC50; i.e., the concentration of compound required to inhibit 50% of kinase activity.

UniProt: Q7Z3E1
Assay: Enzymatic Assay: Displacement of Probe A, a biotinylated probe binding to the TIPARP active site, was measured using a time-resolved fluorescence energy transfer (TR-FRET) assay. 20 nL of a dose response curve of each test compound was spotted in black 384-well polystyrene proxiplates (Perkin Elmer) using a Mosquito (TTP Labtech). Reactions were performed in a 8 μl volume by adding 6 μL of TIPARP and Probe A in assay buffer (20 mM HEPES pH=8, 100 mM NaCl, 0.1% bovine serum albumin, 2 mM DTT and 0.002% Tween20), incubating with test compound at 25° C. for 30 min, then adding 2 μL of ULight-anti 6×His and LANCE Eu-W1024 labeled streptavidin (Perkin Elmer). The final concentrations of TIPARP and Probe A were 6 nM and 2 nM, respectively. The final concentration of ULight-anti 6×His and LANCE Eu-W1024 labeled streptavidin were 4 nM and 0.25 nM, respectively. Reactions were incubated at 25° C. for an additional 30 min, then read on an Envision platereader equipped with a LANCE/DELFIA top mirror (Perkin Elmer) using excitation of 320 nm and emission of 615 nm and 665 nM with a 90 is delay. The ratio of the 665/615 nm emission were calculated for each well to determine the amount of complex of TIPARP and Probe Ain each well. Control wells containing a negative control of 0.25% DMSO vehicle or a positive control of 100 μM 5-(5-(piperidin-4-yloxy)isoindolin-2-yl)-4-(trifluoromethyl)pyridazin-3(2H)-one were used to calculate the % inhibition.

Target: Orexin/Hypocretin receptor type 1 (SINGLE PROTEIN), Homo sapiens
UniProt: O43613
Assay: Receptor Radioligand Binding Assay: Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1× Pen/Strep, 600 μg/mL G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1× with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2K×G, 10 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at −80° C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and vortexed for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moravek Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM (1-(6,8-difluoro-2-methylquinolin-4-yl)-3-[4-(dimethylamino)phenyl]urea, CAS Registry #288150-92-5). The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-5B674042 diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Target: Muscarinic acetylcholine receptor M3 (SINGLE PROTEIN), Homo sapiens
UniProt: P20309
Assay: Muscarinic 3 Receptor Binding Assay: The muscarinic 3 receptor binding assay was adapted from Perkin Elmer. Briefly, assay buffer (60 μL of pH 7.4 phosphate saline buffer) was added to polypropylene round bottom 96-well microtiter plates, followed by CHO cell suspension expressing the human M3 receptor (1 mg suspension/ml; 20 ug membrane suspension per well). 3H-Scopolamine (20 μL of a 7.5 nM solution) was added to each well and plates were shaken at room temperature for 2 h. Atropine (Sigma-Aldrich, St. Louis, Mo.) was used as a positive control. Test compounds and control samples were prepared in DMSO (20 mM) and diluted to give a final concentration of 20 μM. The reaction mixtures were then added to matrix 96-well GFC filtration microtiter plates that had been previously pretreated with 0.5% polyethylimine (100 μL) for 4 h and filtered. The binding reactions were terminated by filtering through the GFC plates and washing & filtering with ice-cold phosphate saline buffer (5×100 μL). Once the filters were dry, microscint scintillation cocktail (100 μL) was added to each well, allowed to sit for 20 min and the plates analyzed using a TopCount scintillation counter. Test compounds which showed >50% reduction in 3H-scopolamine binding at a final concentration of 20 μM were subjected to further serial dilutions and evaluated at various concentrations to determine their IC50 value. Curve fitting of % inhibition versus concentration using Excell software allowed determination of IC50 values for test compounds.

Target: Histone deacetylase 4 (SINGLE PROTEIN), Homo sapiens
UniProt: P56524
Assay: Inhibition Assay: The potency of Class IIa Histone Deacetylase (HDAC) inhibitors is quantified by measuring the Histone Deacetylase 4 (HDAC4) catalytic domain enzymatic activity using the fluorogenic substrate, Boc-Lys(Tfa)-AMC. The substrate is deacetylated to Boc-Lys-AMC by HDAC4. Cleavage by trypsin results in the release of the fluorophore AMC from the deacetylated substrate. The fluorescence of the sample is directly related to the histone deacetylase activity in the sample.Serially dilute HDAC inhibitor compounds. Serial dilutions of the HDAC inhibitors and control reference compound (1-(5-(3-((4-(1,3,4-oxadiazol-2-yl)phenoxy)methyl)-1,2,4-oxadiazol-5-yl)thiophen-2-yl)-2,2,2-trifluoroethanone) are made by first resuspending the lyophilized compound to a final concentration of 10 mM in 100% dimethyl sulfoxide (DMSO). Stocks of 6 μl aliquots of the 10 mM compound in DMSO are prepared and stored at −2° C.

Assay: PHD enzymatic assay: The PHD enzymatic assay was performed in 0.5 ml of reaction mixture containing the following: purified PHD2181-417 polypeptide (3 μg), synthetic HIF-1α peptide comprising residues [KNPFSTGDTDLDLEMLAPYIPMDDDFQLRSFDQLS] (10 μM, California Peptide Research Inc., Napa, Calif.), and [5-14C]-2-oxoglutaric acid (50 mCi/mmol, Moravek Chemicals, Brea, Calif.) in reaction buffer (40 mM Tris-HCl, pH 7.5, 0.4 mg/ml catalase, 0.5 mM DTT, 1 mM ascorbate) for 10 minutes. Compounds were pre-incubated for 30 min before starting the reaction (all test compounds were dissolved at 10 mM in 100% DMSO (w/v) and were tested with final compound concentrations at 100 μM in 1% DMSO (w/v)). The reaction was stopped by addition of 50 μl of 70 mM H3PO4 and 50 μl of 500 mM NaH2PO4, pH 3.2. Detection of [14C]-succinic acid was achieved by separating from [5-14C]-2-oxoglutaric acid by incubating the reaction mixture with 100 μl of 0.16 M DNP prepared in 30% perchloric acid. Next, 50 μl of unlabeled 20 mM 2-oxoglutaric acid/20 mM succinic acid, serving as carrier for the radioactivity, was added to the mixture, and was allowed to proceed for 30 minutes at room temperature. The reaction was then incubated with 50 μl of 1 M 2-oxoglutaric acid for 30 additional minutes at room temperature to precipitate the excess DNP. The reaction was then centrifuged at 2800×g for 10 minutes at room temperature to separate [14C]-succinic acid in the supernatant from the precipitated [14C]-dinitrophenylhydrazone. Fractions of the supernatant (400 μI) were counted using a beta counter (Beckman Coulter, Fullerton, Calif.). Inhibition of PHD2181-417 activity was measured as a decrease in succinic acid production. The IC50 values were estimated by fitting the data to a three-parameter logistic function using GraphPad Prism, version 4.02 (Graph Pad Software, San Diego, Calif.).

Target: Tyrosine-protein kinase ITK/TSK (SINGLE PROTEIN), Homo sapiens
UniProt: Q08881
Assay: ITK Inhibitor Binding Kinetics: This assay is based on the binding of a proprietary, Alexa Fluor 647-labeled, ATP-competitive kinase inhibitor (kinase tracer-236) to the ITK expression construct in the presence of a Europium-conjugated antibody, resulting in a FRET (fluorescence resonance energy transfer) signal. Displacement of the kinase tracer by compound results in a lower emission ratio upon excitation of the Europium chelate. Candidate compounds are designed as potential irreversible inhibitors of ITK, capable of ligating to an active site cysteine residue resulting in time dependent covalent binding. The time dependent nature of irreversible inhibition is investigated by performing the binding assay with and without a pre-incubation of compound and ITK.

Assay: Time Resolved-Fluorescence Energy Transfer (TR-FRET) Assay: Compounds were profiled for activity against human FABP4 (huFABP4) and/or human FABP5 (huFABP5) in Terbium (Tb) time resolved-fluorescence energy transfer (TR-FRET) assays monitoring the direct binding of Bodipy labeled fatty acid to His6 tagged FABP proteins (huFABP4 was expressed in house in E. Coli and purified, huFABP5 was purchased from Cayman Chemical Co., cat.no. 10010364), bound to Terbium labeled anti His6 tag antibody. Assay read-outs reflected energy transfer, upon binding of the ligand to the FABP protein, from the Terbium donor molecule to the acceptor Bodipy moiety. Final ligand concentration (125 nM) approximated the Kd for each protein.Stock DMSO solutions (1.8 mM) of compounds were serially diluted 3-fold for ten concentrations with 100% DMSO (50 μM to 0.003 μM final compound concentration). 1 μl of these compound dilutions and 1 μl of Bodipy labeled fatty acid 4.5 μM in 100% DMSO (Bodipy FL C11, cat. no. D3862, Invitrogen) were sequentially pipetted in wells of 384-well black polypropylene plates (Thermo Matrix cat. no. 4344). FABP4 or FABP5 protein was then added (28 μl of 64 nM protein in 25 mM Tris pH 7.5, 0.4 mg/ml γ-globulin, 1 mM DTT, 0.012% NP40, final protein concentration: 50 nM). Assay blanks contained ligand, but no protein. Neutral controls contained ligand, but no compound. After adding the detection reagent (Tb antiHis6 antibody, Columbia Biosciences, TB-110, 6 μl of a 24 nM Ab solution in 25 mM Tris pH 7.5, 0.4 mg/ml γ-globulin, final Tb antiHis6 Ab concentration: 4 nM), plates were spun one minute at 1000 rpm. Following an incubation at room temperature with shaking for 30 minutes, plates were read using an Envision reader (Perkin Elmer, Extinction wavelength: 340 nm, Emission: 490 nm and 520 nm, time delay: 100 μs; time window: 200 μs, 50 flashes).Final assay conditions were: 50 nM FABP protein, 125 nM Bodipy labeled fatty acid, 0.009% (vol/vol) NP40, 5.5% (vol/vol) DMSO in a total final assay volume of 36 μl. The assay was performed in triplicate.

Assay: ThermoFluor Assay: ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Development, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation. Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1° C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature.

Assay: Inhibition Assay: Compounds were screened for their ability to inhibit ATR kinase using a radioactive-phosphate incorporation assay. Assays were carried out in a mixture of 50 mM Tris/HCl (pH 7.5), 10 mM MgCl2 and 1 mM DTT. Final substrate concentrations were 10 μM [γ-33P]ATP (3mCi 33P ATP/mmol ATP, Perkin Elmer) and 800 μM target peptide (ASELPASQPQPFSAKKK) (SEQ ID NO:1).Assays were carried out at 25° C. in the presence of 5 nM full-length ATR. An assay stock buffer solution was prepared containing all of the reagents listed above, with the exception of ATP and the test compound of interest. 13.5 μL of the stock solution was placed in a 96 well plate followed by addition of 2 μL of DMSO stock containing serial dilutions of the test compound (typically starting from a final concentration of 15 μM with 3-fold serial dilutions) in duplicate (final DMSO concentration 7%). The plate was pre-incubated for 10 minutes at 25° C. and the reaction initiated by addition of 15 μL [γ-33P]ATP (final concentration 10 μM).The reaction was stopped after 24 hours by the addition of 30 μL 0.1M phosphoric acid containing 2 mM ATP. A multiscreen phosphocellulose filter 96-well plate (Millipore, Cat no. MAPHN0B50) was pretreated with 100 μL 0.2M phosphoric acid prior to the addition of 454 of the stopped assay mixture. The plate was washed with 5×200 μL 0.2M phosphoric acid. After drying, 100 μL Optiphase SuperMix liquid scintillation cocktail (Perkin Elmer) was added to the well prior to scintillation counting (1450 Microbeta Liquid Scintillation Counter, Wallac).

Assay: SHP2 Enzyme Activity Inhibition Assay: Compound powders were dissolved in DMSO to prepare mother liquor.During the experiment, the stock solutions of the compounds were subjected to 3-fold gradient dilution with DMSO, and 10 different test concentrations of each compound were set. 1 μL of each concentration of the compounds was transferred into the wells of detection plates (Corning, Costar 3915), setting two duplicates for each concentration. The protein used was the activated protein SHP2E76A with amino acid mutation at position 76 of the protein, and the substrate used was DiFMUP (Invitrogen, E12020). SHP2E76A protein and substrate were diluted with buffer (0.1 M NaAc (pH 7.2), 0.02% Tween 20, 0.1% BSA, 1 mM EDTA, 5 mM DTT) to a concentration of 1.2 nM and 20 M, respectively. 50 L of enzyme solution was added to the detection wells, followed by 50 L of substrate. On the Spectra max i3 (Molecular Devices) instrument, the fluorescence signal was recorded (Ex 358 nm/Em 455 nm) every minute, from which the product accumulation rate was calculated to characterize the enzyme activity. GraphPad Prism 5 was used for nonlinear regression analysis, and the curve of enzyme activity versus compound concentration was fitted by the equation Y=Bottom+(Top-Bottom)/(1+10{circumflex over ( )}((Log IC50−X)*HillSlope)) to calculate the IC50 value of each compound.

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 μM 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 μL) was dispensed, followed by the addition of 15 μL 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 μL kinase buffer containing 2.45 μM ERK2 IMAP substrate peptides and 75 μM ATP. The final reaction in each well of 25 μL consists of 0.5 nM hERK2, 900 nM unlabeled peptide, 80 nM labeled-peptide, and 30 μM ATP. Phosphorylation reactions were allowed to proceed for 60 minutes and were immediately quenched by the addition of 60 μL IMAP detection beads (1:1000 dilutions) in IMAP binding buffer (Molecular Devices) with 24 mM NaCl. Plates were read on EnVision reader after 60 minutes binding equilibration using Fluorescence Polarization protocol (Perkin Elmer).

Assay: Measuring Inhibition of the TRPA1 Ion Channel: Compounds of Formula (I) inhibit the TRPA1 channel, as shown by measuring the in vitro inhibition of human TRPA1, provided in data tables shown in Table 2, using the procedure outlined in del Camino et al., The Journal of Neuroscience, 30(45):15165-15174 (Nov. 10, 2010), incorporated herein by reference and summarized below. Data for TRPA1 inhibition was obtained by this method for the indicated compounds of Formula (I), with the relevant data included in Table 2 below. All currents were recorded in whole-cell configuration using EPC-9 and EPC-10 amplifiers and Patchmaster software (HEKA) or similar. Patch pipettes had a resistance of 1.5-3 M and up to 75% of the series resistance was compensated. The standard pipette solution consisted of 140 mM CsAsp, 10 mM EGTA, 10 mM HEPES, 2.27 mM, 20 MgCl2, 1.91 mM CaCl2, and up to 0.3 mM Na2GTP, with pH adjusted to 7.2 with CsOH. In addition, a solution containing 145 mM CsCl, 10 mM HEPES, 10 mM EGTA, and up to 0.3 mM Na2GTP and 1 mM MgCl2 (pH 7.2 adjusted with CsOH) can be used. The standard bath solution contained 150 mM NaCl, 10 mM HEPES, 10 mM glucose, 4.5 mM KCl, 1 mM EGTA, 3 mM MgCl2, with pH adjusted to 7.4 with NaOH. In some instances, 2 mM CaCl2 was added in place of EGTA and the concentration of MgCl2 was reduced to 1 mM.Data were collected either by continuous recordings at −60 mV or by applying voltage ramps from a holding potential of −40 mV every 4 s. Continuous recordings were collected at 400 Hz and digitally filtered off-line at 10 Hz for presentation. Voltage ramps were applied from −100 mV or −80 mV to +100 mV or +80 mV over the course of 400 ms, and data were collected at 10 kHz and filtered at 2.9 kHz. Inward and outward currents were analyzed from the ramps at −80 and 80 mV, respectively. Liquid junction potential correction was not used.

Assay: MKNK1 Kinase High ATP Assay: A recombinant fusion protein of Glutathione-S-Transferase (GST, N-terminally) and human full-length MKNK1 (amino acids 1-424 and T344D of accession number BAA 19885.1), expressed in insect cells using baculovirus expression system and purified via glutathione sepharose affinity chromatography, was purchased from Carna Biosciences (product no 02-145) and used as enzyme. As substrate for the kinase reaction the biotinylated peptide biotin-Ahx-IKKRKLTRRKSLKG (SEQ ID NO: 1, C-terminus in amide form) was used, which can be purchased e.g. from the company Biosyntan (Berlin-Buch, Germany).For the assay 50 nL of a 100 fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 μL of a solution of MKNK1 in aqueous assay buffer [50 mM HEPES pH 7.5, 5 mM MgCl2, 1.0 mM dithiothreitol, 0.005% (v/v) Nonidet-P40 (Sigma)] was added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to the enzyme before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 μL of a solution of adenosine-tri-phosphate (ATP, 3.3 mM=>final conc. in the 5 μL assay volume is 2 mM) and substrate (0.1 μM=>final conc. in the 5 μL assay volume is 0.06 μM) in assay buffer and the resulting mixture was incubated for a reaction time of 30 min at 22° C. The concentration of MKNK1 was adjusted depending of the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical concentrations were in the range of 0.003 μg/mL. The reaction was stopped by the addition of 5 μL of a solution of TR-FRET detection reagents (5 nM streptavidine-XL665 [Cisbio Bioassays, Codolet, France] and 1 nM anti-ribosomal protein S6 (pSer236)-antibody from Invitrogen [#44921G] and 1 nM LANCE EU-W1024 labeled ProteinG [Perkin-Elmer, product no. AD0071]) in an aqueous EDTA-solution (100 mM EDTA, 0.1% (w/v) bovine serum albumin in 50 mM HEPES pH 7.5).The resulting mixture was incubated for 1 h at 22° C. to allow the formation of complex between the phosphorylated biotinylated peptide and the detection reagents. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Eu-chelate to the streptavidine-XL. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm were measured in a TR-FRET reader, e.g. a Rubystar (BMG Labtechnologies, Offenburg, Germany) or a Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and at 622 nm was taken as the measure for the amount of phosphorylated substrate. The data were normalised (enzyme reaction without inhibitor=0% inhibition, all other assay components but no enzyme=100% inhibition).

Assay: Phosphodiersterase Evaluation Assay: IMAP TR-FRET Phosphodiersterase Evaluation Assay Kit (Molecular Device) was used for the measurement. Ten μL of a diluted test compound having each concentration and 5 μL of the enzyme PDE10 (BPA Bioscience) that had been diluted to 2 ng/mL with 1×IMAP Reaction Buffer (prepared with 5×included with the kit, 10 mM Tris-HCl, pH=7.2, 10 mM MgCl2, 0.05% NaN3, and 0.1% BSA) containing 0.1% BSA were added to a 384-well plate (Corning). The obtained mixture was then pre-incubated at room temperature for 5 minutes. Thereafter, 5 μL of cAMP substrate solution which was included with the kit and diluted to 400 nM with 1×IMAP Reaction Buffer containing 0.1% BSA, was added to the reaction solution, and the obtained mixture was reacted at room temperature for 60 minutes. Thereafter, 60 μL of an IMAP TR-FRET Binding solution included with the kit was further added to the reaction solution, and the obtained mixture was then left for 3 hours or more. Subsequently, using ARVO SX (PerkinElmer), the fluorescent intensity of Terbium (Emission=490 nm) and TR-FRET (Emission=520 nm) in the reaction solution were measured at an excitation wavelength of 340 nm, so as to calculate the amount of the generated 5′-AMP. The count of a well to which a solvent had been added instead of the test compound was set at 0%, and the count of a well to which the enzyme PDE10 had not been added was set at 100%. Thus, the inhibitory activity of each test compound was calculated.

Assay: transient human FXR/Gal4-luciferase reporter assay: A Gal4-hFXR fusion construct reporter system was used as the primary assay to characterize compound activity. A construct including 5 copies of the Gal4 promoter response element upstream of a firefly luciferase reporter cDNA was stably expressed in HEK293 cells. This reporter cell line was maintained in Dulbecco's Modified Eagle's medium (DMEM; Gibco) supplemented with 1% penicillin-streptomycin (P/S) solution, 500 μg/mL Zeocin and 10% charcoal/dextran-treated fetal bovine serum (cs-FBS) at 37° C. in a humidified 5% CO2 atmosphere. Another plasmid was constructed in which the human cytomegalovirus promoter in the pcDNA3.1 vector directs the expression of the cDNA encoding a fusion protein comprised of the DNA binding domain from the Gal4 transcription factor fused to the ligand binding domain from human FXR.The day prior to transfection, the reporter cells in culture are detached from the plate with trypsin and plated into a T75 flask at a sufficient density to achieve approximately 90% confluence the next morning. The transfection reagents are prepared by separately diluting 25 μg of the pcDNA3.1-Gal4-FXR plasmid into 1.87 mL of Opti-MEM (Thermo-Fisher), and 40 μL of Lipofectamine 2000 (Thermo-Fisher) into 1.87 mL of Opti-MEM, and then adding the diluted DNA solution into the diluted Lipofectamine 2000 solution and incubating at room temperature for 15-20 minutes. The mixture is further diluted with 10 mL of a solution comprised of DMEM, 10% cs-FBS, and 1% P/S immediately prior to transferring to the cells. The maintenance culture media is aspirated from the cells and the final transfection mixture is added before the cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. This protocol can be scaled up, and the transiently transfected cells can be cryopreserved in an assay-ready format.For compound testing, 100 nL of the compounds (serial dilutions in DMSO) are dispensed with an Echo acoustic dispenser (Labcyte) into the wells of a Corning/Costar clear bottom 384-well white plate. The transfected cells are harvested, counted, and diluted such that 10-25,000 cells in 25 μL are plated into each well of the 384-well compound assay plate. The compound-treated cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. The next morning 25 μL of Steady-Glo (Promega) are added to each well of the plate, the mixture is incubated for 15 min. with shaking, and luminescence is measured on an Envision (Perkin Elmer) plate reader. Background counts from cells treated with DMSO alone are subtracted from all raw counts, and the corrected values are converted to a percentage of the control response attained with 8 μM GW-4064. These data are fit to a 4-parameter log agonist-response equation to calculate an EC50 value.

The reaction solution was added to Oasis® μ Elution plate (Waters) and eluted with 150 μL of mixture of acetonitrile:isopropanol (=2:3). 150 μL of MicroScinti-40 (Perkin-Elmer Corp.) were added to the eluted solution and the mixture was sufficiently stirred, and an amount of [14C]-TG produced in the reaction was determined by measuring using TopCount-NXT (Perkin-Elmer Corp.).The inhibitory ratio was calculated by the following equation.Inhibitory ratio (%)=(1−(TG amount when the test compound was added−blank TG amount)/(control TG amount−blank TG amount))×100Here, a count of [14C]-TG in the solution where the reaction was carried out without adding the test compound was regarded control TG amount, and a count of [14C]-TG in the solution to which the test compound and highly DGAT1 expressing expresSF+® microsome were not added was regarded as blank TG amount. Further, a concentration of test compound required to inhibit the synthesis of [14C]-TG by 50% (IC50 value) was calculated by Prism 5.01 (GraphPad Softwear).
