UniProt: Q9H7B4
Assay: SMYD3 Biochemical Assay: The assays were all performed in a buffer consisting of 25 mM Tris-Cl pH 8.0, 1 mM TCEP, 0.005% BSG, and 0.005% Tween 20, prepared on the day of use. Compounds in 100% DMSO (1 ul) were spotted into a 384-well white opaque OptiPlate using a Bravo automated liquid handling platform outfitted with a 384-channel head (Agilent Technologies). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMYD3, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the SMYD3 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD3 for 30 min at room temperature, then a cocktail (10 ul) containing SAM and MEKK2 was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: SMYD3 was 0.4 nM, 3H-SAM was 8 nM, MEKK2 was 12 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (10 ul) to a final concentration of 100 uM, which dilutes the 3H-SAM to a level where its incorporation into MEKK2 is no longer detectable. Radiolabeled MEKK2 was detected using a scintillation proximity assay (SPA). 10 uL of a 10 mg/mL solution of SPA beads in 0.5 M citric acid was added and the plates centrifuged at 600 rpm for 1 min to precipitate the radiolabeled MEKK2 onto the SPA beads. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of 3H-labeled MEKK2 as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).% Inhibition Calculation% ⁢ ⁢ inh = 100 - ( dpm cmpd - dpm min dpm max - dpm min ) × 100Where dpm=disintegrations per minute, cmpd=signal in assay well, and min and max are the respective minimum and maximum signal controls.Four-Parameter IC50 FitY = Bottom + ( Top - Bottom ) ( 1 + ( X IC 50 ) Hill ⁢ ⁢ CoefficientWhere top and bottom are the normally allowed to float, but may be fixed at 100 or 0 respectively in a 3-parameter fit.

Assay: In Vitro Assay: The effectiveness of compounds of the present invention as ROCK inhibitors can be determined in a 30 μL, assay containing 20 mM HEPES, pH 7.5, 20 mM MgCl2, 0.015% Brij-35, 4 mM DTT, 5 μM ATP and 1.5 μM peptide substrate (FITC-AHA-AKRRRLSSLRA-OH). 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: Kinase Assay: For the assay, 11 different concentrations in the range from 20 μM to 0.073 nM were prepared from a 2 mM solution of the test substance in DMSO. For the assay, 50 nl of the respective solution were pipetted into a black low-volume 384-well microtitre plate (Greiner Bio-One, Frickenhausen, Germany), 2 μl of a solution of Irak4 in assay buffer [50 mM HEPES pH 7.5, 5 mM MgCl2, 1.0 mM dithiothreitol, 30 μM activated sodium orthovanadate, 0.1% (w/v) of bovine gamma-globulin (BGG) 0.04% (v/v) nonidet-P40 (Sigma)] were added and the mixture was incubated for 15 min to allow prebinding of the substances to the enzyme prior to the kinase reaction. The kinase reaction was then started by addition of 3 μl of a solution of adenosine triphosphate (ATP, 1.67 mM=final concentration in 5 μl of assay volume: 1 μM) and peptide substrate (0.83 μM=final concentration in 5 μl assay volume: 0.5 μM) in assay buffer, and the resulting mixture was incubated at 22° C. for the reaction time of 45 min. The concentration of the Irak4 was adjusted to the respective activity of the enzyme and set such that the assay was carried out in the linear range. Typical concentrations were in the order of about 0.2 nM. The reaction was stopped by addition of 5 μl of a solution of TR-FRET detection reagents [0.1 μM streptavidin-XL665 (Cisbio Bioassays; France, catalogue No. 610SAXLG) and 1.5 nM anti-phosphoserin antibody [Merck Millipore, STK Antibody, catalogue No. 35-002] and 0.6 nM LANCE EU-W1024-labelled anti-mouse-IgG antibody (Perkin-Elmer, product No. AD0077, alternatively it is possible to use a terbium cryptate-labelled anti-mouse-IgG antibody from Cisbio Bioassays) in aqueous EDTA solution (100 mM EDTA, 0.4% [w/v] bovine serum albumin [BSA] in 25 mM HEPES pH 7.5).

Assay: ThermoFluor Assay: ThermoFluor is a fluorescence based assay that estimates ligand binding affinities by measuring the effect of a ligand on protein thermal stability (Pantoliano, M. W., Petrella, E. C., Kwasnoski, J. D., Lobanov, V. S., Myslik, J., Graf, E., Carver, T., Asel, E., Springer, B. A., Lane, P., and Salemme, F. R. (2001) High-density miniaturized thermal shift assays as a general strategy for drug discovery. J Biomol Screen 6, 429-40, and Matulis, D., Kranz, J. K., Salemme, F. R., and Todd, M. J. (2005) Thermodynamic stability of carbonic anhydrase: measurements of binding affinity and stoichiometry using ThermoFluor. Biochemistry 44, 5258-66). This approach is applicable to a wide variety of systems, and rigorous in theoretical interpretation through quantitation of equilibrium binding constants (KD).In a ThermoFluor experiment where protein stability is monitored as the temperature is steadily increased, an equilibrium binding ligand causes the midpoint of an unfolding transition (Tm) to occur at a higher temperature. The shift in the melting point described as a ΔTm is proportional to the concentration and affinity of the ligand. The compound potency may be compared as a rank order of either ΔTm values at a single compound concentration or in terms of KD values, estimated from concentration response curves.

Target: Toll-like receptor 7 (SINGLE PROTEIN), Homo sapiens
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.

Assay: Human alpha7 nAChR Binding Assay: The ability of compounds to displace binding of radioactive ligands from human α7 nAChR was determined, as a measure of the affinity of the compounds for these ligand-gated ion channels. The [125I]-αBungarotoxin competition binding assay was performed under contract by Cerep Poitiers, France following published the methods (Sharpies et al., J Neurosci. 2000; 20(8):2783-91). SH-SY5Y cells stably expressing human α7 nicotinic acetylcholine receptors, grown to confluency in 175 cm2 flasks, were washed briefly with warm PBS containing (in mm): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.) and scraped into cold phosphate buffer. Cells were washed by centrifugation for 3 min at 500×g and resuspended in 10 mL of ice-cold phosphate buffer. The suspension was homogenized for 10 sec using an Ultraturax and centrifuged for 30 min at 45,000×g. The pellet was resuspended in phosphate buffer (0.5 mL per original flask). SH-SY5Y membranes (30 μg protein) were incubated in a total volume of 2 mL in 50 mM phosphate buffer with 0.05 nM [125I]-αBgt and serial dilutions of test compound. Nonspecific binding was determined in the presence of α-bungarotoxin (1 μM). Samples were incubated for 120 min at 37° C. The reaction was terminated by filtration through Whatman GFA/E filter paper (presoaked overnight in 0.3% polyethyleneimine in PBS), using a Brandel Cell Harvester. Each condition was measured in duplicate. Filters were counted for radioactivity using a scintillation counter. The results were expressed as a percent inhibition of control specific binding obtained in the presence of the test compounds where Inhibition (%)=100−[(measured specific binding/control specific binding)×100].

PRKD2 (PKD2) reactions contained 0.64-5.84 ng enzyme, 25 μM ATP (Km), 2 μM of Ser/Thr 17 (Z′-LYTE peptide substrate), 10 mM MgCl2, 0.01% BRIJ-35, 1 mM EGTA in 50 mM HEPES, pH 7.5. RPS6KA2 (RSK3) reactions were conducted similarly, and contained 0.5-9 ng enzyme, or 10 μM ATP (Km) and 2 μM Ser/Thr 06 peptide. After the 1-hour kinase reaction incubation, 5 μL of a 1:256 and 1:4096 dilution of Z′-LYTE Development Reagent A was added to the PRKD2 (PKD2) and RPS6KA2 (RSK3) reactions, respectively. The extent of kinase reactions, resulting in a change of FRET signal of the peptide substrate, was measured, and inhibition for each kinase was measured with respect to DMSO control and reported as an average of duplicate measurements.

The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement.Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 uL/well, incubated for 120 min and finally 10 uL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist. The IC50 value (the concentration of compound needed to inhibit 50% of the agonistic response) is determined and may be normalized using the obtained IC50 value of an on-plate reference compound. Optimized conditions were achieved by adjustment of pipetting speed and cell splitting regime. The calculated IC50 values may fluctuate depending on the daily cellular assay performance. Fluctuations of this kind are known to those skilled in the art. In the case where IC50 values have been determined several times for the same compound, the geometric mean has been given.

Assay: Biological Assay: The compounds of the invention inhibit RORgammaT activity. Activation of RORgammaT activity can be measured using, e.g., a biochemical TR-FRET assay. In such an assay, interaction of cofactor-derived peptides with human RORgammaT-Ligand Binding Domain (LBD) can be measured. The TR-FRET technique is a sensitive biochemical proximity assay that will give information concerning the interaction of a ligand with the LBD, in the presence of cofactor-derived peptides (Zhou et al., Methods 25:54-61, 2001).To identify novel antagonists of RORgammaT, an assay was developed which employs the interaction of RORgammaT with its co-activator peptide SRC1_2. This peptide mimics the recruitment of co-activators to RORgammaT through its interaction with the LXXLL (SEQ ID NO:1) (e.g., NR box) motifs (Xie et al., J. Immunol. 175: 3800-09, 2005; Kurebayashi et al., Biochem. Biophys. Res. Commun. 315: 919-27, 2004; Jin et al., Mol. Endocrinology 24:923-29, 2010).

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.
