Assay: MOR cAMP Agonist and Antagonist Assays: CHO Tag-lite human mOR stable cell line from Cisbio (NCBI accession number: NM_000914.3, Bedford, Mass.) were seeded and grown to approximately 80% confluence in Ham F-12 with 10% FBS, 50 U/ml penicillin, 50 μg/ml streptomycin, 2 mM Hepes, and 1 mg/ml geneticin (Invitrogen, Carlsbad, Calif.). Cells were then harvested using accutase (Corning. Coming, N.Y.), centrifuged at 1300 RPM for 5 min, and plated at 5000 cells per 5 μL per well in a 5× dilution of stimulation buffer consisting of the HTRF cAMP Gi kit, water and IBMX at 0.5 mM (Cisbio, Bedford, Mass.) in white HTRF low volume 384 well plates (Cisbio, Bedford, Mass.). Plates were then incubated at 37° C. in 5% CO2 for 10 minutes. For the agonist assay, forskolin was added to a final concentration of 4 μM. For the antagonist assay, forskolin (4 μM) and DAMGO at EC90 final concentration were added. Test compounds were dissolved in DMSO and water, and then serially diluted to working concentrations such that the concentration of DMSO was less than 0.1%. Diluted test compounds were added at 2.5 μL per well, and plates were incubated at 37° C., and 5% CO2 for 15 minutes, and then at room temperature for 15 minutes. Next 5 μl/well of cAMP Eu-cryptate and 5 μl/well of anti-cAMP-d2 (both diluted 1:20 in lysis buffer) were added, and plates were incubated at room temperature for 1 hour. Following incubation, plates were read in a Synergy Neo2 multi-mode reader (Biotek, Winooski, Vt.). Plate reader settings were set to time resolved fluorescence with excitation at 330 nm and emissions of 620 nm and 665 nm. Emission fluorescence was normalized (665/620 nm signal×1000). For the agonist assay, data was normalized using the maximal DAMGO response. Measurements were performed in triplicate and the dose response was fit using nonlinear regression.

Assay: PDK1 kinase assay: PDK1 (amino acids 51-359) and AKT2 (amino acids 140-467 fused to PIFtide, amino acids EEQEMFRDFDYIADW) were expressed as N-terminally tagged GST fusion proteins in insect cells and purified to homogeneity. Enzyme activity was determined in a coupled PDK1/AKT/FAM-crosstide assay and phosphorylation of FAM-crosstide was determined by standard IMAP protocol (Molecular Devices). For inhibition studies, compounds were titrated 4-fold in DMSO and diluted 40-fold into assay buffer (10 mM Tris HCl pH7.2; 10 mM MgCl2; 0.01% Triton X-100; 1 mM DTT) containing PDK1, AKT2, and FAM-crosstide (final concentrations: 0.75 nM PDK1, 10 nM unphosphorylated AKT2, and 100 nM crosstide substrate). The kinase reaction was initiated by adding ATP to a final concentration of 40 μM of PDK1 and incubated at 25° C. for 30 min. To detect assay product, the kinase reaction was combined with Progressive Binding Solution (1:600 Progressive Binding Reagent, 50% Buffer A, 50% Buffer B, Molecular Devices) in a 1:3 ratio. The mixture was incubated for 2 hours at 25° C. and the plate was scanned on an Analyst AD with excitation at 485 nm and emission at 530 nm. The fluorescence polarization value P is defined by the equation below. The value mP is generated by multiplying the P value for each reaction well by a factor of 1000. The value ΔmP for each well is the mP value for that well minus the mP value for the average negative control. P=(Fpar−Fperp)/(Fpar+Fperp)  Eq.:Where par is fluorescence intensity parallel to the excitation plane; and perp is fluorescence intensity perpendicular to the excitation plane. ΔmP values were plotted as a function of compound concentration and the data were analyzed with a 4-parameter fit using GraphPad Prism software.

Assay: MNK2a In Vitro Kinase Assay (Assay 2): ASSAY SETUP: The inhibition of kinase activity of MNK2a was assessed using pre-activated GST-MNK2a. The white, 384-well OptiPlate F plates were purchased from PerkinElmer. The ADP-Glo Kinase Assay (including ultra pure ATP) was purchased from Promega (V9103). Activated MNK2a was obtained as described in WO2011/104340. The unlabeled eIF4E peptide (NH2-TATKSGSTTKNR-CONH2), differing from Seq. ID No. 5 of WO 2011/104340 by the C-terminal CONH2 group, was purchased from Thermo Fisher Scientific. All other materials were of highest grade commercially available. Compounds are tested in either serial dilutions or single dose concentrations. The compound stock solutions are 10 mM in 100% DMSO The serial compound dilutions are prepared in 100% DMSO followed by 1:27.3 intermediate dilution in assay buffer. The final DMSO concentration in assay will be <3%.In the 384-well plates 3 μl of test compound from the intermediate dilutionis mixed with 4 μl of the activated MNK2 enzyme (final concentration of 10 nM) and 4 μl of the peptide (final concentration of 25 μM)/ultra pure ATP (final concentration of 20 μM), all dissolved in assay buffer. This step is followed by an incubation time of 90 min, then 10 μl of ADP Glo reagent are added, followed by 40 min of incubation. Then 20 μl of kinase detection reagent are admixed. The plates are sealed and after an incubation period of 30 min, the luminescence signal is measured in an Envision reader to determine the amount of produced ADP. All incubation steps are performed at room temperature.The assay buffer consists of 20 mM HEPES, 2 mM DTT, 0.01% BSA, 20 mM MgCl2 and 0.1% Pluronic F-127.Each assay microtiter plate contains wells with vehicle controls instead of compound (1% DMSO in water) as reference for the high signal (100% CTL, high signal), and wells containing a potent MNK2 inhibitor (final 20 μM, 1% DMSO) as reference for low signal (0% CTL, low signal).The luminescent signal generated is proportional to the ADP concentration produced and is correlated with activated MNK2 activity. The analysis of the data is performed by the calculation of the percentage of ATP consumption of activated MNK2 in the presence of the test compound compared to the consumption of ATP in the presence of activated MNK2 without compound. RLU(sample)−RLU(low control))*100/(RLU(high value)−RLU(low control)) [RLU=relative luminescence units]An inhibitor of the MNK2 enzyme will give values between 100% CTL (no inhibition) and 0% CTL (complete inhibition). Values of more than 100% CTL are normally related to compound/sample specific physico-chemical properties (e.g. solubility, light absorbance, fluorescence).IC50 values based on dose response curves are calculated with the AssayExplorer software.

Assay: HTRF FRET Assay: BACE1: A homogeneous time-resolved FRET assay can be used to determine IC50 values for inhibitors of the soluble human BACE1 catalytic domain. This assay monitors the increase of 620 nm fluorescence that resulted from BACE1 cleavage of an APPswedish APPswe mutant peptide FRET substrate (QSY7-EISEVNLDAEFC-Europium-amide). This substrate contains an N-terminal QSY7 moiety that serves as a quencher of the C-terminal Europium fluorophore (620 nm Em). In the absence of enzyme activity, 620 nm fluorescence is low in the assay and increased linearly over 3 hours in the presence of uninhibited BACE1 enzyme. Inhibition of BACE1 cleavage of the QSY7-APPswe-Eu substrate by inhibitors is manifested as a suppression of 620 nm fluorescence.Varying concentrations of inhibitors at 3× the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 μl) for 30 minutes at 30° C. in reaction buffer containing 20 mM Na-Acetate pH 5.0, 10% glycerol, 0.1% Brij-35 and 7.5% DSMO. Reactions are initiated by addition of 10 μl of 600 nM QSY7-APPswe-Eu substrate (200 nM final) to give a final reaction volume of 30 μl in a 384 well Nunc HTRF plate. The reactions are incubated at 30° C. for 1.5 hours. The 620 nm fluorescence is then read on a Rubystar HTRF plate reader (BMG Labtechnologies) using a 50 millisecond delay followed by a 400 millisecond acquisition time window. Inhibitor IC50 values are derived from non-linear regression analysis of concentration response curves. Ki values are then calculated from IC50 values using the Cheng-Prusoff equation using a previously determined μm value of 8 μM for the QSY7-APPswe-Eu substrate at BACE1.

Assay: HTRF PI3K Biochemical Assay: Compounds are serially diluted (3-fold in 100% DMSO) across a 384-well polypropylene source plated from column 3 to column 12 and column 13 to column 22, to yield 10 concentration dose response for each test compound. Columns 1, 2, 23 and 24 contain either only DMSO or pharmacological known control inhibitor. Once titrations are made, 2.5 nL of the compounds on 384 well plates are reformatted and transferred by acoustic dispense in quadruplicates to a 1536 assay plate (Greiner) to assay across all four PI3K isoform enzymes.The PI3-Kinase biochemical assay was optimized using the HTRF kit provided by Upstate (Millipore). The assay kit contains six reagents: 1) 4× Reaction Buffer; 2) native PIP2 (substrate); 3) Stop (EDTA); 4) Detection Mix A (Streptavidin-APC); 5) Detection Mix B (Eu-labeled Anti-GST plus GST-tagged PH-domain); 6) Detection Mix C. In addition, the following items were obtained or purchased; PI3Kinase (alpha 14-602, beta 14-603, gamma 14-558 and delta 14-604 from Upstate; Millipore), dithiothreitol (Sigma, D-5545), Adenosine-5′ triphosphate (InVitrogen, Cat#AS001A), native PIP3 (PI(3,4,5)P3, diC8, H+, CELLSIGNALS, INC. Cat #907) DMSO (Sigma, 472301).PI3Kinase Reaction Buffer is prepared by dilution the stock 1:4 with de-ionized water. DTT, PIP2 and Biotin-PIP3 were added to 1536 assay plate at a final concentration of 5 mM, 5 mM and 25 nM on the day of use. Enzyme addition and compound pre-incubation are initiated by the addition of 1.25 ul of PI3K (at twice its final concentration) in the 1× reaction buffer to all wells using a BioRaptor. Plates are incubated at RT for 15 minutes. Reactions are initiated by addition of 1.25 ul of 2× substrate solution (PIP2 and ATP in 1× reaction buffer) using BioRaptor. Plates are incubated in humidified chamber at RT for one hour. Reactions are quenched by addition of 0.625 uL of stop solution to all wells using the BioRaptor. The quenched reactions are then processed to detect product formation by adding 0.625 uL of Detection Solution to all wells using the BioRaptor (Detection mix C, Detection Mix A, and Detection Mix B combined together in an 18:1:1 ratio prepared 2 hours prior to use). Following a one hour incubation in the dark, the HTRF signal is measured on the Envision plate reader set for 330 nm excitation and dual emission detection at 620 nM (Eu) and 665 nM (APC).

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.

UniProt: Q9NWZ3
Assay: IRAK4 Kinase Assay: The kinase activity of IRAK4 is determined by its ability to catalyze the phosphorylation of a fluorescent polypeptide substrate. The extent of phosphorylation is measured using the IMAP technology (Molecular Devices) where the phosphorylated fluorescent substrate binds to the large M(III)-based nanoparticles which reduces the rotational speed of the substrate and thus increases its fluorescent polarization (FP).20 μL reaction mixture contains 10 mM TriHCl, pH 7.2, 0.5 nM GST tagged IRAK4 (SignalChem), 100 nM fluorescent peptide substrate (RP7030, Molecular Devices), 100 μM ATP, 1 mM DDT, 1 mM MgCl2, and 0.01% Tween 20. The reaction is initiated by the addition of ATP. After incubation for 30 minutes at 25° C., 60 μL of Progressive IMAP Reagent (Molecular Devices) is added to stop the reaction. Change in RP7030's FP is determined by a FP reader (Analyst HT, LJL BioSystems).
