Assay: MYLK/MLCK Assay: MYLK dissociation constants (Kd) for compounds were determined using the DiscoverX KdELECT platform. The MYLK kinase (accession number NP_444254.3) was labeled with a DNA tag for subsequent qPCR readout while a known active site binding ligand (staurosporine) was immobilized on a solid support (beads). Test compounds were prepared as 111X stocks in 100% DMSO and Kds were determined using an 11-point 3-fold compound dilution series with three DMSO control points. The compounds were then diluted directly into the assays such that the final concentration of DMSO was 0.9%. The assay plates were incubated at room temperature with shaking for 1 hour to equilibrate. The affinity beads were washed (lx PBS, 0.05% Tween 20) to remove unbound kinase and quantify MYLK captured on solid support by qPCR. The Kd was determined by measuring the amount of MYLK captured on the solid support as a function of the test compound concentration. The Kd values were calculated by fitting dose-response curves to the Hill binding equation using the Levenberg-Marquardt algorithm.

UniProt: Q9NR96
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: Sodium-dependent serotonin transporter (SINGLE PROTEIN), Homo sapiens
UniProt: P31645
Assay: Functional Uptake Assay (hSERT): Inhibition of human serotonin reuptake transporter was assayed using the recombinant human serotonin transporter expressed in HEK-293 cells. HEK-293 cells expressing human serotonin transporter were plated before the assay. Test compound and/or vehicle was preincubated with cells in modified HEPES buffer pH 7.1 or pH 7.4 for 20 minutes at 18 to 25° C. and 65 nM [3H]serotonin was then added for an additional timed incubation period (ten to thirty minutes). Cells with internalized [3H]serotonin were washed and the amount of tritium taken into cells is counted using a liquid scintillation counter to determine [3H]serotonin uptake. Non-specific binding of tritium was measured in a control reaction containing 10 uM fluoxetine, and was subtracted from the counts for assays to correct for non-specific binding of tritium. Reduction of [3H]serotonin uptake by 50 percent or more (50%) relative to an uninhibited control reaction indicates significant inhibitory activity. Compounds were screened at 10, 1, 0.1, 0.01 and 0.001 uM. The reference compound for the assay was fluoxetine, for which the IC50 value of 7.1 nM was obtained in a typical experiment.

Target: Sodium-dependent dopamine transporter (SINGLE PROTEIN), Homo sapiens
UniProt: Q01959
Assay: Functional Uptake Assay (hDAT): Inhibition of human dopamine reuptake transporter was assayed using the recombinant human dopamine transporter expressed in either CHO-K1 or HEK293 cells using a published method (Pristupa, Z. B. et al., Mol. Pharmacol. 45: 125-135, 1994). Either CHO-K1 or HEK293 cells expressing human recombinant dopamine transporter were plated before the assay. Test compound and/or vehicle was preincubated with cells in modified HEPES buffer pH 7.1 or pH 7.4 for 20 minutes at 18 to 25° C. and 50 nM [3H]dopamine was then added for an additional timed incubation period (10 to 30 minutes). After washing the cells to remove [3H]dopamine not internalized, the cells were lysed, and the amount of tritium in the lysate was measured using a liquid scintillation counter to determine [3H]dopamine uptake. Non-specific binding of tritium was measured in a control reaction containing 10 uM nomifensine, and was subtracted from the counts for assays to correct for non-specific binding of tritium. Reduction of [3H]dopamine uptake by 50 percent or more (50%) relative to an uninhibited control reaction indicates significant inhibitory activity. Compounds were screened at 10, 1, 0.1, 0.01 and 0.001 uM. The reference compound for the assay was nomifensine, for which the IC50 value of 11 nM was obtained in a typical experiment.

Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well.

Assay: Receptor Binding Assay: The hMOP receptor binding assay was performed as homogeneous SPA-assay (scintillation proximity assay) using the assay buffer 50 mM TRIS-HCl (pH 7.4) supplemented with 0.052 mg/ml bovine serum albumin (Sigma-Aldrich Co. St. Louis. Mo.). The final assay volume (250 ul/well) included 1 nM of [N-allyl-2.3-3H]naloxone as ligand (PerkinElmer Life Sciences. Inc. Boston. Mass. USA). and either test compound in dilution series or 25 uM unlabelled naloxone for determination of unspecific binding. The test compound was diluted with 25% DMSO in H2O to yield a final 0.5% DMSO concentration. which also served as a respective vehicle control. The assay was started by adding wheat germ agglutinin coated SPA beads (GE Healthcare UK Ltd. Buckinghamshire. UK) which had been preloaded with hMOP receptor membranes (PerkinElmer Life Sciences. Inc. Boston. Mass. USA). After incubation for 90 minutes at RT and centrifugation for 20 minutes at 500 rpm the signal rate was measured by means of a 1450 Microbeta Trilux ??-counter (PerkinElmer Life Sciences/Wallac. Turku. Finland). Half-maximal inhibitory concentration (IC50) values reflecting 50% displacement of [3H]naloxone-specific receptor binding were calculated by nonlinear regression analysis and Ki values were calculated by using the Cheng-Prusoff equation.

Assay: Enzyme Assay: The affinity of compound binding to wild type and mutant human MET kinases is measured using Invitrogen's LanthaScreen Eu Kinase Binding technology. Briefly, GST-tagged recombinant human MET kinase domain from Signal Chem (see Table 8 below for concentration in assay) is incubated with 50 nM Alexa-Fluor® Tracer 236 (Invitrogen Cat No. PR9078A) and 2 nM Europium-anti-GST (Invitrogen Cat. No. A151 6) along with test compound in a buffer consisting of 25 mM HEPES, pH 7.4, 10 mM MgCl2, 0.01% Triton X-100, 1 mM DTT, and 2% DMSO. Compounds are typically prepared in a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 60-minute incubation at 22° C., the reaction is measured using a PerkinElmer EnVision multimode plate reader via TR-FRET dual wavelength detection, and the percent of control (POC) calculated using a ratiometric emission factor. 100 POC is determined using no test compounds and 0 POC is determined using a concentration of control compound that completely inhibits the enzyme
