Assay: Electrophysiological Assay (EP) (In Vitro Assay): Patch voltage clamp electrophysiology allows for the direct measurement and quantification of block of voltage-gated sodium channels (NaV's), and allows the determination of the time- and voltage-dependence of block which has been interpreted as differential binding to the resting, open, and inactivated states of the sodium channel (Hille, B., Journal of General Physiology (1977), 69: 497-515).The following voltage clamp electrophysiology studies were performed on representative compounds using cells heterologously expressing Nav1.7 or Nav1.5 channels. cDNAs for Nav1.7 (NM_002977) and Nav1.5 (AC137587) were stably expressed in Chinese Hamstr Ovary (CHO) cells and CHL (Chinese Hamster Lung) cells respectively. Sodium currents were measured in the whole-cell configuration using Syncropatch 384PE (NanIon Technologies, Germany). 1NPC®-384 chips with custom medium resistance and single hole mode are used. Internal solution consists of (in mM): 110 CsCl, 10 CsCl, 20 EGTA, and 10 Hepes (pH adjusted to 7.2); and external solution contains (in mM): 60 NMDG, 80 NaCl, 4 KCl, 1 MgCl2, 2 CaCl2, 2 D-Glucose monohydrate, 10 Hepes (pH adjusted to 7.4 with NaOH).After system flushing, testing compounds are dissolved in external solution containing 0.1% Pluronic F-127. The chip is moved into the measuring head and the instrument primes the chip with external and internal solutions. 10l cells are added to the chip from a cell hotel, and a negative pressure of −50 mBar is applied to form a seal. Following treatment with seal enhancer solution and wash-off with external solution, negative pressure of −250 mbar is applied for 1 second to achieve the whole-cell configuration, followed by three washing steps in external solution. 20 μl of compounds is added to 40 μl in each well (1:3 dilution of compounds), and after mixing, 20 μl is removed so the volume is retained at 40 μl. After approximately 13 minutes recordings, 20 μl/well of 2 uM TTX, or 333 uM Tetracaine (for Nav1.5) is added to achieve full block.For voltage protocol, an holding potential of −50 mV is applied during the whole experiment. A depolarizing step is applied to −10 mV for 10 ms, followed by a hyperpolarization step to −150 mV for 20 ms to allow channel recovery from inactivation. A second depolarizing step is applied from −150 mV to −10 mV for 10 ms, where currents were measured to derive blocking effects of compounds. Inhibition is determined based on 7.5 min of compound incubation.

Assay: Exemplary c-Kit Biochemical Assay: Assays for biochemical cell-based activity of c-kit kinase are known in the art, for example, as described in U.S. Pat. Nos. 7,498,342 and 7,846,941, the disclosures of which are hereby incorporated by reference as it relates to such assays. The c-kit (or kinase domain thereof) is an active kinase in AlphaScreen. IC50 values are determined with respect to inhibition of c-Kit kinase activity, where inhibition of phosphorylation of a peptide substrate is measured as a function of compound concentration. Compounds to be tested were dissolved in DMSO to a concentration of 20 mM. These were diluted 30 μl into 120 μl of DMSO (4 mM) and 1 μl was added to an assay plate. These were then serially diluted 1:3 (50 μl to 100 μl DMSO) for a total of 8 points. Plates were prepared such that each kinase reaction is 20 μl in 1× kinase buffer (50 mM HEPES, pH 7.2, 5 mM MgCl2, 5 mM MnCl2, 0.01% NP-40, 0.2% BSA), 5% DMSO and 10 gM ATP. Substrate was 100 nM biotin-(E4Y)3 (Open Source Biotech, Inc.). C-kit kinase was at 0.1 ng per sample. After incubation of the kinase reaction for 1 hour at room temperature, 5 μl of donor beads (Streptavidin coated beads (Perkin Elmer Life Science) final concentration 1 μg/ml) in stop buffer (50 mM EDTA in 1× kinase buffer) was added, the sample was mixed and incubated for 20 minutes at room temperature before adding 5 μl of acceptor beads (PY20 coated beads (Perkin Elmer Life Science) final concentration 1 μg/ml) in stop buffer. The samples were incubated for 60 minutes at room temperature and the signal per well was read on AlphaQuest reader. Phosphorylated substrate results in binding of the PY20 antibody and association of the donor and acceptor beads such that signal correlates with kinase activity. The signal vs. compound concentration was used to determine the IC50.

Assay: NAMPT Enzyme Assay: To measure the inhibition of NAMPT activity hNAMPT protein stock and anti 6His-Tb (Cisbio; Cat. No. 61HISTLB) is diluted to 3× final concentration with assay buffer (50 mM Tris-HCl (pH7.5), 1 mM DTT, 100 mM NaCl, 10 mM MgCl2, 0.005% Tween 20). To this solution is added test compounds or vehicle control (DMSO) and BodiPY ligand (structure below). The plate is shaken for 1-2 min, sealed and incubated for 1 hour at rt in the dark. The TR-FRET signal is measured using BMG Pherastar (Lanthascreen protocol on BMG Pherastar). Excitation was carried out at 320 nm, and the ratio of emission of BodiPY (520 nm) to terbium (486 nm) was determined. Concentration response curves are generated by calculating the excitation increase in test compound-treated samples relative to DMSO-treated controls. For the assay method described above, test compound percent inhibition values at a single concentration are calculated relative to control (DMSO) treated samples. Compound concentration response curves are fitted to generate IC50 values from those curves. One skilled in the art will appreciate that these values generated either as percentage inhibition at a single concentration or IC50 values are subject to experimental variation.

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.

Assay: LC-MS/MS-Based NSD2 Enzymatic Assay: This assay employed LC-MS/MS technology to monitor the SAH production from the NSD2 enzymatic reaction. The enzymatic reaction was performed in white proxiplate plus 384-well microplate (Perkin Elmer). The reaction mixture (10 μL) were composed of 8 nM NSD2 [1-1365], 1 M SAM (USB, 10601) and 400 nM nucleosome (purified from mouse liver) in reaction buffer (20 mM Tris-HCl, pH at 8.0, 0.01% Tween 20, 10 mM MgCl2, 50 mM NaCl, 1 mM DTT, 1 mM TCEP (pH7.5)). After 90 min incubation at room temperature, 3 μL quenching solution containing 2.5% TFA with 320 nM d4-SAH was added to stop the reaction.For the inhibition assay, compound solutions were transferred into the wells by Mosquito (TTP LabTech). The inhibition assays were carried out by preincubating various concentrations of the inhibitor with 5 uL reaction mixture containing 16 nM NSD2 [1-1365] and 2 uM SAM (USB, 10601) in reaction buffer. After 20 min preincubation, 5 uL solution containing 800 nM nucleosome (purified from mouse liver) in reaction buffer was added to initiate the reaction. The reaction was stopped by 3 μL quenching solution containing 2.5% TFA with 320 nM d4-SAH after 90 min.The SAH production from the enzymatic assays were monitored by LC-MS/MS on an API 4000 triple quadrupole mass spec with Turbolon Spray (Applied Biosystem) coupled with Prominenece UFLC(Shimazu). Liquid chromatography was performed on a Chromolith FastGradient HPLC column (RP-18e, 25-2 mm, from Merck) at a flow rate of 0.8 ml/min. The column was connected directly to the turbo ion electrospray operating in the positive-ion mode. Mobile phase A is 0.1% FA and 2% methanol in water and mobile phase B is 0.1% FA in ACN. Injection volume was 3 μl and the autosampler was kept at 4 degree. SAH and d4-SAH were simultaneously monitored. Data were acquired and processed by Analyst software.To quantify the formed SAH, d4-SAH was added as internal standard (IS). A series of SAH (Sigma, A9384) solution at varying concentration (1-500 nM in reaction buffer) was mixed with quenching solution mentioned above. Then LC-MS/MS was carried out on API 4000 LC/MS/MS system to detect both SAH and d4-SAH. The plot of SAH peak area/IS peak area vs SAH concentration was used to generate the normalization factor of SAH. The SAH production from real enzymatic reaction was derived from the standard curve of SAH. The down-limit of our system for the detection of SAH is around 1-2 nM, and the linear range can reach up to 500 nM.

UniProt: Q9NYK1
Assay: TLR7/8/9 Inhibition Reporter Assay: 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 NMDA receptor; GRIN1/GRIN2B (PROTEIN COMPLEX), Homo sapiens
UniProt: Q05586
Assay: NMDA receptor FLIPR 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 149 mM NaCl, 4 mM KCl, 2 mM CaCl2, and 1.5 mM MgCl2, 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 (149 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 EC80 (standard assay) or EC40 (HTS assay) is used to maximize the assay's signal window or the ability to detect NMDA receptor antagonists and negative allosteric modulators, respectively. 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.

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.

Assay: Cytokine Assays: Cytokine inhibitory activity is determined by measuring the effect of test agent on the release of the cytokines IL-4, IL-13 and IFNγ from human peripheral blood mononuclear cells (PBMCs) stimulated with the T-cell mitogen phytohemagglutinin-L (PHA-L). At the time of assay, human PBMCs (Astarte Biologics) are removed from cryopreservation, thawed quickly at 37° C., diluted in assay medium (RPMI-Gibco 1640 medium, 10% heat inactivated fetal bovine serum (HIFBS), 2 mM glutamine and 10 mM HEPES pH 7.4) and then centrifuged at 250×g for 5 minutes. The resulting cell pellet is re-suspended in assay medium to a concentration of approximately 5×106 cells/mL and 50 μL of this cell suspension (approximately 250,000 cells) is added to each well of a 384-well cell culture microtiter plate (Perkin Elmer). Varying concentrations of test compound are then diluted in assay medium and added to the assay plate wells in a volume of 25 μL. After −10 minutes at room temperature (21° C.) the cells are stimulated by the addition of 25 μL of PHA-L (14 μg/mL; Millipore) and the assay plate is placed in an incubator at 37° C. in a humidified environment in 5% carbon dioxide. The final assay conditions are approximately 250,000 human PBMCs per well in assay medium containing 3.5 μg/mL PHA-L and the indicated final concentration of test compound (approximately 10 μM to 9.5 μM by 4-fold dilution). The final concentration of DMSO in the assay is approximately 0.25%. After 48 hours, the assay plate is removed from the incubator and centrifuged at 250×g for 5 minutes. A portion of the resulting cell supernatant is then used to determine the amount of IL-4, IL-13 and IFNγ in each well. Cytokine measurements are made using human IL-4, IL-13 or IFNγ HTRF assay kits (CisBio) following the manufacturer's assay protocol. The concentrations and resulting effect values for tested compounds are plotted and the concentration of compound required for 50% effect (IC50) is determined with a four-parameter logistic dose response equation (E-WorkBook, ID Business Solutions Ltd.).
