Target: Glutamate NMDA receptor; GRIN1/GRIN2B (PROTEIN COMPLEX), Homo sapiens
UniProt: Q13224
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.

Assay: FGFR Enzymatic Assay: The inhibitor potency of the exemplified compounds was determined in an enzyme discontinuous assay that measures peptide phosphorylation using FRET measurements to detect product formation. Inhibitors were serially diluted in DMSO and a volume of 0.2 μL was transferred to the wells of a 384-well plate. A 5 μL/well volume of enzyme isoforms of FGFR (-1, -2, -3 wild-type and mutant isoforms, -4) including phosphorylated and un-phosphorylated proteins diluted in assay buffer (50 mM HEPES, 10 mM MgCl2, 1 mM EGTA, 0.01% Tween-20, 5 mM DTT, pH 7.5) was added to the plate and pre-incubated with inhibitor for 5 to 15 minutes at ambient temperature. Appropriate controls (enzyme blank and enzyme with no inhibitor) were included on the plate. The reaction was initiated by the addition of a 5 μL/well volume containing both biotinylated EQEDEPEGDYFEWLE peptide substrate (SEQ ID NO: 1) and ATP in assay buffer. The 10 μL/well reaction concentration of the peptide substrate was 500 nM whereas the ATP concentration was maintained near or below the ATP Km. The ATP Km values were pre-determined in a separate series of experiments. The reaction plate was incubated at 25° C. for 1 hr and the reactions were ended with the addition of 5 μL/well of quench solution (50 mM Tris, 150 mM NaCl, 0.5 mg/mL BSA, pH 7.8; 45 mM EDTA, 600 nM staurosporin, with Perkin Elmer Lance Reagents at 3.75 nM Eu-antibody PY20 and 180 nM APC-Streptavidin). The plate was allowed to equilibrate for 10 minutes at ambient temperature before scanning on a PheraStar plate reader (BMG Labtech) instrument.

Assay: cAMP ASSAY: The activation of the SSTR4 receptor (Gi coupled) causes an inhibition of intracellular cAMP after stimulation with Forskolin, which can be quantifiable by use of a suitable assay Kit and an adequate plate reader. This technique is used to characterize pharmacological effects of the SSTR4 receptor agonists by use of hSSTR4 expressing H4 cells.Compounds are dissolved and diluted in DMSO. The final test solution contains 1 DMSO. The cAMP standard (Lance cAMP 384 Kit; PerkinElmer, Cat #AD0264) is prepared in assay buffer (HBSS with 0.1% BSA, 5 mM HEPES, 0.5 M IBMX, pH 7.4) containing 1% DMSO and the cAMP standard curve is included at least on one plate. Cells are centrifuged and suspended in assay buffer (incl. 1:100 diluted Alexa antibody).For the assay 5 μl of a cell suspension (approximately 5000 cells/well) incl. Alexa antibody (diluted 1:100) are added into a 384 well MTP microtitre plate excepting one row or column (depending on the plate layout), which is reserved for the standard curve. Then 2 μl of compound sample is added as concentration response curve (e.g. 1e-5 M to 6e-10 M), usually in triplicates. Each assay contains incubations with vehicle controls instead of compound as controls for non-inhibited cAMP generation (100% CTL; high values) and incubations with 1 μM Somatosatin as controls for full inhibition and background (0% CTL; low values). After approximately 10-15 min incubation time 3 μl Forskolin (dissolved in DMSO, final conc. 15 μM) is added. Then the plates are shaken briefly and incubated for 60 min at room temperature. After 60 min 10 μl of the detection mix is added into all wells followed by an additional incubation period of 1 h. The plates are read in a suitable plate reader.The analysis of the data is based on the ratio of the time-resolved fluorescence measurements of donor and acceptor fluorophore (Ex: 320 nm; Em1: 665 nm; Em2: 615 nm; ratio 665/615). From this ratio, cAMP concentrations are calculated from standard curve and the EC50 is estimated by least square curve fit program.

Assay: Jak 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: Btk In Vitro Inhibitory Assay: Human Btk kinase (Genbank accession # NP_000052) was purified from insect cells as a full-length construct containing a N-terminal 6×-His tag. Btk kinase activity was determined using a radiometric filter binding assay. Measurements are performed in a low μL reaction volume 384-well assay plates. BTK enzyme (8 nM final in reaction), inhibitor (at requested doses), and 0.2 mg/mL peptide substrate (Poly-Glu-Tyr, 4:1 ratio) are incubated in a reaction buffer composed of 20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO for 15 min. followed by addition of 1 μM ATP to start the assay. Kinase reactions are carried out for 120 min. at room temperature. The reaction was stopped by spotting of reaction sample onto P81 cationic exchange paper (Whatman). Unbound phosphate was removed by extensive washing of filters in 0.75% Phosphoric acid. After subtraction of background derived from control reactions containing inactive enzyme (via addition of saturating EDTA), kinase activity data for each dose of compound tested was expressed as the percent of remaining kinase activity in test samples compared to vehicle (dimethyl sulfoxide) reactions.

Assay: Cell-Based NOP Assay: Formula (I) compounds were tested for antagonism of the nociceptin receptor (NOP) in a cell-based cAMP assay, using the LANCE cAMP Detection Kit, Perkin Elmer (Waltham, Mass.). This assay (LANCE cAMP) is a homogeneous, time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay designed to measure cAMP produced upon modulation of adenylyl cyclase activity by G protein-coupled receptors (GPCRs).ProtocolCells expressing human opioid NOP (ValiScreen cell line, cat #ES-230-C Perkin Elmer (Waltham, Mass.) were dispensed in simulation buffer (5 mM Hepes, 0.1% BSA, 0.5 mM IBMX in Hanks Buffered Saline Solution) at 2.5 μL cells per well (400 cells/well) into a 1536 white TC-treated assay plate. Compound was then added and plates were incubated for 15 minutes at room temperature. To each well was added 2.5 μL of a solution containing forskolin (3 μM final) and nociceptin peptide (390 pM final) diluted in stimulation buffer, and the plates were incubated for 30 minutes at room temperature. To each well was dispensed 5 μL of LANCE Ultra detection (1:300 dilution of anti-cAMP ULight with a 1:100 dilution of Eu-cAMP tracer diluted in cAMP Detection Buffer) reagent, and the plates were incubated for 1 hr at room temperature. The plate was then read on the ViewLux microplate reader (Perkin Elmer, Waltham, Mass.) using the LANCE 1536 protocol with 60 second exposure times and 50 μs delay. This protocol has an excitation wavelength of 340 nm (DUG11 filter) and emission wavelengths of 615 nm (Eu-Donor) and 665 nm (Alexa 647 cAMP antibody acceptor).Data AnalysisData was analyzed, normalized, and visualized using ACAS (John McNeil & Co.). Efficacy was calculated using activity of the vehicle (DMSO) as 0% efficacy and the activity of the corresponding reference positive control (SCH 221510, Tocris Bioscience (Pittsburgh, Pa.), Catalog number 3240) as 100% efficacy. Activity was calculated as the ratio of donor and acceptor emissions. All curve fits and IC50 determinations were performed using a non-linear regression model. The IC50 value was measured as the concentration at which half-maximal response was calculated.

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.
