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: High Throughput Biochemical Assay: EGFR activity was measured using KinEASE (Cisbio), a time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay. In this assay, EGFR-catalyzes the phosphorylation of a universal Tyrosine kinase peptide substrate labeled with XL665. Europium conjugated phosphor-tyrosine specific antibody binds the resulting phosphorylated peptide. Formation of phosphorylated peptide is quantified by TR-FRET with Europium as the donor and XL665 the acceptor. The assay was performed in two main steps. The first step is the kinase reaction step and the second step is the detection step with TR-FRET reagents. In brief, test compounds 1:3 serially diluted in DMSO were delivered into Corning white, low volume, non-binding 384 well plates using the Echo 550 acoustic liquid dispenser (Labcyte®). EGFR enzyme (Human EGFR, cytoplasmic domain [669-1210] from Carna Biosciences Cat. No. 08-115) and substrates TK substrate-biotin (included in Cisbio HTRF KinEASE-TK kit Cat. No. 62TK0PEJ) were dispensed into assay plates using a Multi-Flo (Bio-Tek Instruments). The standard 10 μL reaction mixture contained 6 μM ATP (1×Km) or 12 μM ATP (2×Km), 1 μM biotinylated peptide, 0.3 nM EGFR (for 1×Km ATP) or 0.1 nM EGFR (for 2×Km ATP) in reaction buffer (10 mM MOPs, pH 7.0, 1.5% Glycerol, 0.5 mg/ml BSA, 10 mM Mg-Acetate, 1 mM DTT, 0.025% NP-40). After 60 min of incubation at room temperature, 10 μL of Stop and Detect Solution (1:400 Europium Cryptate labeled anti-phosphorylated peptide antibody solution and 125 nM strepavidin-XL665 Tracer in a 50 mM Hepes pH 7.0 detection buffer containing sufficient EDTA) was added. The plate was then further incubated for over 60 minutes at room temperature and read using an Envision 2103 Multilabeled reader (PerkinElmer) with excitation/emission/FRET emission at 340 nm/615 nm/665 nm, respectively.

Target: Xanthine dehydrogenase/oxidase (SINGLE PROTEIN), Homo sapiens
UniProt: P47989
Assay: Inhibition Assay: The inhibition of the activity of xanthine oxidase (XO) is tested through a coupled enzymatic reaction of xanthine oxidase, horseradish peroxidase (HRP) and a substrate thereof. First, xanthine oxidase oxidizes hypoxanthine to produce xanthine and hydrogen peroxide, and further oxidizes xanthine to produce uric acid and hydrogen peroxide. Then, hydrogen peroxide reacts with 10-acetyl-3,7-dihydroxyphenoxazine (Ampliflu Red) under catalytic action of horseradish peroxidase so as to produce resorufin, a compound with strong fluorescence. The fluorescence intensity of resorufin is determined by using a fluorescence microplate, which is in direct proportion to the activity of xanthine oxidase.

Assay: Cell-Based Assay of NHE-3 Activity (Pre-Incubation Inhibition): Rat and human NHE-3-mediated Na+-dependent H+ antiport was measured using a modification of the pH sensitive dye method originally reported by Paradiso (Proc. Natl. Acad. Sci. USA. (1984) 81(23): 7436-7440). PS120 fibroblasts stably expressing human NHE3 and NHERF2 were obtained from Mark Donowitz (Baltimore, Md.). Opossum kidney (OK) cells were obtained from the ATCC and propagated per their instructions. The rat NHE-3 gene (GenBank M85300) was introduced into OK cells via electroporation, and cells were seeded into 96 well plates and grown overnight. Medium was aspirated from the wells then incubated for 30 min at 37° C. with NH4Cl-HEPES buffer (20 mM NH4Cl, 80 mM NaCl, 50 mM HEPES, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, pH 7.4) containing 5 μM BCECF-AM. Cells were washed once with Ammonium free, Na+-free HEPES (100 mM choline, 50 mM HEPES, 10 mM glucose, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, pH 7.4) and incubated in the same buffer for 10 minutes at room temperature to lower intracellular pH with 0-30 μM test compound. After incubation, NHE-3-mediated recovery of neutral intracellular pH was initiated by addition of Na-HEPES buffer containing 0.4 μM ethyl isopropyl amiloride (EIPA, a selective antagonist of NHE-1 activity that does not inhibit NHE-3). Changes in intracellular pH were monitored using a FLIPR Tetra® (Molecular Devices, Sunnyvale, Calif.) by excitation at λex 439 to 505 nm, and measuring BCECF fluorescence at λem 538 nm. The initial rate of the fluorescence ratio change was used as a measure of NHE-mediated Na+/H+ activity, and reported as the change in fluorescence ratio per minute. Initial rates were plotted as the average of 2 or more replicates, and pIC50 values were estimated using GraphPad Prism.

Assay: Biochemical HTRF Assay Protocol: The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer #PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction. Plates were shaken and centrifuged and then incubated 60 minutes at room temperature and then read on a Perkin Elmer Envision (λex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading. After normalization to untreated controls, the percent inhibition of the HTRF signal at each compound concentration was calculated.

Assay: In Vitro Assay: DHODH Enzymatic Assay: The following assay is referred to herein as the DHODH Enzymatic Assay. To detect DHODH enzyme activities, dichloroindophenol (DCIP) is added as the final electron acceptor in the assay. DCIP can accept electrons from the reduced coenzyme Q generated in the assay, or from dihydroorotate (DHO) via FMN by binding presumably to the ubiquinone pocket. DCIP solutions are blue, with an intense absorbance around 600 nm, but becomes colorless upon reduction (J. Biol. Chem. (1986) 261, 11386). The assay buffer contained 50 nM HEPES, pH 7.5, 150 mM NaCl, 0.5 mM EDTA, and 0.1% Triton X-100 in MilliQ water. Substrate consisting of 20 mM DHO, 5 mM CoQ6, and 1 mM DCIP in assay buffer, initiates the reaction. The assay is run in end-point mode by quenching the reaction with the potent DHODH inhibitor brequinar. Absorbance measurements were obtained using the BMG Phera Star plate-reading spectrophotomer. Purified human DHODH was purchased from Proteros (cat. No. PR-0044). Chemicals were purchased from Sigma-Aldrich, Teknova, and Avanti Polar Lipids. Liquid handling was performed using Labcyte Echo and Formulatrix Tempest.

Assay: Compound Profiling Methods: Strains expressing SCD1 or SCD5 as the sole desaturase, the human SCD1 and SCD5 genes were used to evaluate inhibition of SCD1/SCD5 using reduced growth as a surrogate for SCD inhibition. These yeast strains express human SCD1 or SCD5 from a plasmid harbored in a strain in which the yeast OLE1 gene is deleted.All compound profiling experiments were performed using the same basic protocol. Yeast were cultured using standard techniques in complete synthetic media lacking uracil and containing yeast nitrogen base supplemented with 2% (w/v) glucose (SD-Ura) Starter cultures were inoculated in 3 mL SD-Ura media containing 0.01% tween and 0.2 mM palmitoleic and oleic acid. Cultures were incubated overnight in a 30° C. shaker incubator (225 rpm). Saturated morning cultures were centrifuged, washed in SD-Ura media lacking TWEEN-20 and fatty acids, and then diluted 1:20 in fresh SD-Ura media also lacking TWEEN-20 and fatty acids. Cells were grown for 6 h to an  (optical density) of 0.4-0.8 at 30° C. with shaking.Compound stocks (10 mM in 100% DMSO) were arrayed into 384-round well, v-bottom polypropylene plates and diluted according to indicated dilution factors. Compound administration was performed in two separate steps. First, 15 μL of SD-Ura was dispensed into clear 384-well assay plates using a MULTIDROP Combi reagent dispenser. The diluted compound stock plates were then applied to the assay plates using an automated workstation (Perkin Elmer JANUS) outfitted with a 384-pin tool containing slotted pins that deliver 100 nL of compound. The cultures described above were centrifuged and washed with media lacking TWEEN-20 or oleic and palmitoleic acids. Cultures were then resuspended at a 2-fold concentrated  of 0.02 (final  of 0.0.01) in SD-Ura. 15 μL of diluted culture was then dispensed into the pinned assay plate to achieve 30 μL of the 1× culture (0.01) and a top drug concentration of 33.3 μM.After yeast delivery, assay plates were incubated under humidified conditions at 30° C. for 40 h. Yeast growth was monitored by reading the  of each well using a microplate reader (Perkin Elmer EnVision). Data were analyzed as follows. Raw data were processed by background subtracting and converting values to a percent of the nontreated condition for that strain [(EXP-0.035)/(DMSO-0.035)×100%].

Assay: Radioligand Binding Assay: The following examples of the in vitro effects of the disclosed compounds are prophetic. An example of an in vitro assay method for assessing the receptor ligand binding activity of the disclosed compounds is given below. Competition binding studies can be performed with the allosteric antagonist [.sup.3H]methoxyPEPy to determine if the disclosed compounds interact with the well-characterized allosteric binding site for the mGluR5 NAM MPEP.The allosteric antagonist MPEP analog [.sup.3H]methoxyPEPy is used to evaluate the ability of test compounds to interact with the MPEP site on mGluR5 (Cosford et al., Bioorg. Med. Chem. Lett. 2003, 13, 351). Membranes are prepared from rat mGluR5 HEK293 cells (Rodriguez et al., Mol. Pharmacol. 2005, 68, 1793). Compounds are diluted in assay buffer (50 mM Tris/0.9% NaCl, pH 7.4) to a 5.times. stock and 100 .mu.L test compound is added to each well of a 96 deep-well assay plate. 300 .mu.L aliquots of membranes diluted in assay buffer (40 .mu.g/well) are added to each well. 100 .mu.L [.sup.3H]methoxyPEPy (2 nM final concentration) is added and the reaction is incubated at room temperature for 1 hour with shaking. After the incubation period, the membrane-bound ligand is separated from free ligand by filtration through glass-fiber 96 well filter plates (Unifilter-96, GF/B, PerkinElmer Life and Analytical Sciences, Boston, Mass.). The contents of each well are transferred simultaneously to the filter plate and washed 3-4 times with assay buffer using a cell harvester (Brandel Cell Harvester, Brandel Inc., Gaithersburg, Md.). 40 .mu.L scintillation fluid is added to each well and the membrane-bound radioactivity determined by scintillation counting (TopCount, PerkinElmer Life and Analytical Sciences). Non-specific binding is estimated using 5 .mu.M MPEP. Concentration response curves were generated using a four parameter logistical equation in GraphPad Prism (GraphPad Software, Inc., La Jolla, Calif.).
