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.

Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
Assay: In Vitro Kinase Assay: In vitro kinase assays described below can be used to determine the activity of a test compound for inhibiting the activity of JAK1 kinase. The test compounds were dissolved in dimethyl sulfoxide and diluted with water to a serial concentration gradient as required in the experiment. JAK1 substrates (Cell Signaling Technology, Catalog Number: 1305s) and ATP (2 mM) solution were diluted with water to obtain a final concentration of 20 uM ATP and 1.2 uM substrate solution. The appropriate amount of JAK1 kinase (Invitrogen, Catalog Number: pv4774) was mixed with 4x buffer (prepared by user, and comprising 50 mM HEPES, pH 7.3, 125 mM NaCl, 24 mM MgCl2, 1.25 mM DTT) to a final concentration of 8 ng/uL. To each well of a microplate [DELFIA Streptavidin-coated clear plate (Perkin Elmer, Catalog Number: AAAND-0005)]17.5 uL of ATP/substrate mixture, 5 uL of an aqueous solution of a test compound (5 uL of pure water only were added to the control and blank), and 7.5 uL of the kinase solution prepared above (4x buffer only was added to the control) were added. Each well was mixed sufficiently, then incubated at room temperature (27° C.) for 50 minutes, washed with wash buffer, and dried three times, then HRP conjugated antibody was added [Phospho-Tyrosine Mouse mAb (P-Tyr-100) (HRP Conjugate, Cell Signaling Technology, Catalog Number: 5465)], and incubated for 1 hour. The microplate was washed with wash buffer and dried three times, and then TMB (Sigma, Catalog Number: T4444) was added, and incubated for 5 to 15 minutes to allow for color change. Stop solution (1 N sulfuric acid solution) was added to stop the reaction. Absorbance was measured on a Novostar microplate reader at a wavelength of 450 nm. IC50 values of test compounds was calculated from the data of the test compounds in inhibiting the activity of JAK1 kinase at different concentrations.

Target: Nuclear receptor ROR-gamma (SINGLE PROTEIN), Homo sapiens
UniProt: P51449
Assay: RORgamma Assay: The RORγ assay system was purchased from Indigo Biosciences. This nuclear receptor assay utilizes a human cell line that has been engineered to express a hybrid form of the Human RAR-related Orphan Receptor Gamma (RORγ) at high levels. The N-terminal DNA binding domain (DBD) of the native RORγ receptor was substituted with the yeast GAL4-DBD to generate the GAL4-RORγ hybrid nuclear receptor. The reporter cell line is transfected with a plasmid that encodes the beetle luciferase gene under the control of the GAL4 upstream activating sequence (UAS). GAL4 binds to the UAS and increases transcription of downstream target genes. The GAL4-RORγ hybrid is constitutively active; therefore, the principle application of this reporter assay system is to screen test compounds to quantify inverse-agonist activities against human RORγ. To assess the RORγ inverse-agonist activity of the test compounds, reporter cells were plated in white 96-well plates in triplicate and were treated with DMSO (vehicle) or test compound (concentration ranges of 0.4-200 nM or 2-1000 nM) at 37° C. with 5% CO2 in a humidified atmosphere for 23 hours. After this incubation, luciferin was added to the wells and luciferase activity was determined by measuring the luminescence signal using a BMG Pherastar microplate reader. Viability was determined using the Live Cell Multiplex Assay (Indigo Biosciences). Values from test compound samples were normalized to those from DMSO-treated samples. Data were analyzed using GraphPad Prism version 6.00 for Windows (GraphPad Software, La Jolla Calif. USA). A non-linear regression analysis with log (inhibitor) vs. normalized response using a variable slope was applied to fit the data and determine the IC50 values for inhibition of RORγ and cell viability.

UniProt: Q02127
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.

Target: Toll-like receptor 7 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NYK1
Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at a final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Blue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Target: Glutamate receptor ionotropic, NMDA 2B (SINGLE PROTEIN), Homo sapiens
UniProt: Q13224
Assay: Standard cell-based calcium flux assay: NMDA receptors are ion channels that are highly permeable to Ca2+ ions, rendering it possible to monitor NMDA receptor function using cell-based calcium flux assay. In this assay, co-agonists glutamate and glycine are added to cells heterologously expressing human GluN1/GluN2B NMDA receptors to initiate cellular Ca2+ influx. The time course of the changes in intracellular calcium is measured using a fluorescent dye and a FLIPR (Fluorometric Imaging Plate Reader) device.Twenty four hours before measurements, the expression of the NMDA receptors in the stable cell line is induced with Tet-On inducible system in the presence of a non-selective NMDA receptor blocker. On the day of the experiment, cell culture media is carefully washed and the cells are loaded with Calcium 5 Dye Kit (Molecular Devices) in dye loading buffer containing 137 mM NaCl, 4 mM KCl, 2 mM CaCl2, 0.5 mM MgCl2 (standard assay) or 1.5 mM MgCl2 (HTS assay), 10 mM HEPES and 5 mM D-glucose; pH 7.4. After 1 h incubation at the room temperature, the dye is washed away with the assay buffer (137 mM NaCl (standard assay) or 150 mM (HTS assay), 4 mM KCl (standard assay) or 3 mM (HTS assay), 2 mM CaCl2, 0.01 mM EDTA, 10 mM HEPES and 5 mM D-glucose; pH 7.4) In the FLIPR TETRA reader, various concentrations of the test compounds are added to the cells for 5 min while fluorescence is monitored to detect potential agonist activity. Next, co-agonists, glutamate and glycine are added for another 5 minutes. The concentration of glutamate corresponding to EC40 (standard assay) is used to maximize the assay's signal window and ability to detect NMDA receptor antagonists and negative allosteric modulators. A saturating concentration (10 μM) of glycine is also present in the assay. A non-selective NMDA receptor antagonist, (+)MK-801 is used as a positive control for antagonist activity. The fluorescent signal in the presence of test compounds is quantified and normalized to the signal defined by the appropriate control wells.

UniProt: Q14833
Assay: Metabotropic Glutamate Receptor Activity: In the first mode, a range of concentrations of the disclosed compounds are added to cells, followed by a single fixed concentration of agonist. If the compound acts as a potentiatior, an EC50 value for potentiation and a maximum extent of potentiation by the compound at this concentration of agonist is determined by non-linear curve fitting. If the compound acts as a noncompetitive antagonist, an IC50 value is determined by non-linear curve fitting. In the second mode, several fixed concentrations of the disclosed compounds are added to various wells on a plate, followed by a range in concentrations of agonist for each concentration of disclosed compound. The EC50 values for the agonist at each concentration of compound are determined by non-linear curve fitting. A decrease in the EC50 value of the agonist with increasing concentrations of the sample compound (a leftward shift of the agonist concentration-response curve) is an indication of the degree of mGluR4 potentiation at a given concentration of the sample compound. A decrease in the maximal response of the agonist with increasing concentrations of the sample compounds, with or without a rightward shift in agonist potency, is an indication of the degree of noncompetitive antagonism at mGluR4. The second mode also indicates whether the sample compounds also affect the maximum response to mGluR4 to agonists.

Assay: Btk Enzyme Activity Assay A: Btk enzyme activity is measured using the IMAP (immobilized metal ion affinity-based fluorescence polarization) assay as outlined below. Btk enzyme (His-Btk (Millipore catalog #14-552), is diluted to 0.4 U/mL in KR buffer (10 mM Tris-HCl, 10 mM MgCl2, 0.01% Tween-20, 0.05% NaN3, 1 mM DTT, 2 mM MnCl2, pH 7.2).Serial dilution log 10 from 2 mM to 63.2 nM of test compounds are made in 100% DMSO. The dilutions in DMSO are then diluted 50-fold in KR-buffer. Final compound concentration range in the assay from 10 μM to 0.316 nM. 5 μL/well of test compound in KR buffer (final DMSO concentration in the assay is 1%) is mixed with 5 μl/well of 0.4 U/mL Btk enzyme (final concentration in the assay is 0.1 U/mL). Test compounds and Btk enzyme are pre-incubated 60 minutes at room temperature, before adding 5 μL/well of 200 nM Fluorescin labeled substrate peptide (Blk/Lyntide substrate, e.g. #R7188/#R7233, Molecular Devices) in KR-buffer. Final peptide substrate concentration in assay is 50 nM. The kinase assay is started by adding 5 μL/well of 20 μM ATP in KR-buffer (final ATP concentration is 5 μM ATP, Km ATP in Btk IMAP assay). Following incubation for 2 h at room temperature the enzyme reaction is stopped by adding 40 μL/well IMAP Progressive Binding Solution (according to suppliers (Molecular Devices) protocol using 75% 1× buffer A and 25% 1x buffer B with 1:600 Progressive Binding Solution). After 60 min incubation at room temperature in the dark the FP signal is read. Fluorescence at 535 nm is measured using parallel and perpendicular filters to determine differences in rotation due to binding of the phosphorylated substrate peptide to the beads. Values are calculated as percentage of the difference in readout (ΔmPi) of the controls with and without ATP. EC50 values are determined by curve fitting of the experimental results using Activity Base.

Assay: Biochemical Assay of FASN: The biochemical FASN activity testing was performed as 384 well two-time-point kinetic fluorescence intensity assay format in Greiner low volume medium binding 384-well black microtiter plates in a total assay volume of 8 μl and was used for high throughput screen. In each well 3 μl 40 nM human recombinant full-length fatty acid synthase (produced in-house in SF9 cells) were dispensed in the following assay buffer: 50 mM potassium phosphate buffer pH 7.0, 0.005% (w/v) BSA, 2 mM Glutathione, 0.02% Tween-20. Then 2 μl of 200 μM NADPH in assay buffer were added, followed by the addition of the test compounds in 10 dilution concentrations starting with 30 μM (final concentration) to get a final DMSO content of 1% (v/v). The mixture was incubated for at least 15 min at room temperature. After the pre-incubation the enzymatic reaction was started by the addition of 2 μl substrate solution (80 μM acetyl-CoA, 240 μM malonyl-CoA). A first fluorescence intensity measurement (time point one) was performed with an Envision multimode reader (Perkin Elmer LAS Germany GmbH) at excitation wavelength 340 nm (lamp mode) and emission wavelength 460 nm. The reaction was incubated for 30 minutes at room temperature. After this the fluorescence intensity was measured again in the Envision using the same parameters as described above (second time point measurement). The data were analysed by subtracting the first time point measurement value from the second time point measurement value (after the enzymatic reaction). The differences of the emission signals were determined. These reflect directly the conversion rate of NADPH. The full value used was the inhibitor-free reaction. A pharmacological zero value was used like GSK837149A (Sigma-Aldrich) in a final concentration of 5-10 μM. The inhibitory values (IC50) were determined using either the program Symyx Assay Explorer® or Condosseo® from GeneData.
