Assay: MAO-B Inhibition Assay: Recombinant human MAO-B (0.06 mg/mL; Sigma Aldrich) was used as source of MAO-B enzyme activities. The assay was performed in a similar way as for human SSAO/VAP-1 (Example 5) except, the substrate benzylamine was used at 100 μM. Briefly, in a standard 96 well plate assay 50 μL of purified human SSAO/VAP-1 (0.25 μg/mL) in 0.1 M NaPO4 buffer (pH 7.4) was added into each well. Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 4-9 data points, typically in the micromolar or nanomolar range after incubation with human SSAO/VAP-1 for 30 min at 37 °C. After 30 min incubation, 50 μL of the reaction mixture containing 600 μM benzylamine (Sigma Aldrich), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 0.1 M NaPO4 buffer (pH 7.4) were added to the corresponding well. The fluorescence unit (RFU) was read every 2.5 min for 30 min at 37 °C. excitation 565 nm and emission 590 (Optima; BMG labtech). The slope of the kinetics for each well was calculated using MARS data analysis software (BMG labtech) and this value was used to deduce the IC50 value (Dotmatics).

Target: Nuclear receptor ROR-gamma (SINGLE PROTEIN), Homo sapiens
UniProt: P51449
Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 384-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer].

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease.

UniProt: P41180
Assay: Agonistic Activity Assay: 293E cells (EBNA1-expressing IIEK293 cells, ATCC No. CRL-10852) were cultured in DMEM (1.0 g/ml Glucose-containing Dulbecco's modified Eagle medium, Nacalai Tesque) containing 10% bovine fetal serum in the presence of 250 ug/ml of G418. The cells were seeded on a 10 cm-diameter petri dish at 1.8Ã¿106 cells/15 ml, and left to stand in a CO2 incubator (5% CO2, 37° C.) for 24 hours. Thereafter, human CaSR expression plasmid hCaSR/pcDNA3.1 was transfected with transfection reagent Mirus Trans IT 293 (Takara Bio). Following static culture in a CO2 incubator for 24 hours, the cells were harvested with 10% bovine fetal serum-containing DMEM and seeded on a poly-D-lysine coat 384 well plate (Falcon) at 15,000 cells/well. Following static culture in a CO2 incubator for 24 hours, the medium was removed and the resultant was added with 50 ul/well of Ca2+ fluorescent indicator Calcium 4 Assay Kit (Molecular Devices) dissolved in an assay buffer (146 mM NaCl, 5 mM KCl, 1 mM MgSO4, 1 mg/ml Glucose, 20 mM HEPES (PH 7.2), 1.5 mM CaCl2), and left to stand at 37° C. for an hour and then at room temperature for 30 minutes to allow intake of the indicator. The above-mentioned 384-well plate was transferred to FLIPR (Molecular Devices) and added with 12.5 ul/well of a compound dissolved in a 0.1% BSA-containing assay buffer to measure 3-minute change in the fluorescence intensity.

Target: Glycylpeptide N-tetradecanoyltransferase (SINGLE PROTEIN), Trypanosoma brucei brucei (strain 927/4 GUTat10.1)
UniProt: Q388H8
Assay: Enzyme Inhibition Assay: Measurements were performed using a modification of the scintillation proximity assay platform described previously by Georgopapadakou, N. H. et al. (22nd International Congress on Chemotherapy, 2001, Abstract P16.001). Compounds were solubilised in DMSO at a top concentration of 10 mM and serially diluted in half log steps to achieve a range of final assay concentrations of 100 uM to 1 nM. Compound at each concentration (100-fold final) was added to white 384 well plates in a volume of 0.5 ml. Human, A. fumigatus, T. brucei or L. major N-myristoyl transferase enzyme, dissolved to a working concentration of 10 nM in assay buffer (30 mM Tris/HCl pH 7.4, 0.5 mM EGTA, 0.5 mM EDTA, 1.25 mM DTT, 0.1% Triton X-100), was then added to columns 1 to 11 and 13 to 23 of the plates in a volume of 20 ml. To columns 12 and 24, 20 ml assay buffer was added to provide a no enzyme control. Following a 5 minute incubation at room temperature the substrates (GCGGSKVKPQPPQAK(Biotin)-Amide and myristoyl coenzyme A), dissolved in assay buffer, were added to all wells in a volume of 20 ml to start the reaction. The final concentrations of peptide and 3H-myristoyl coenzyme A were 0.5 mM and 125 nM respectively and the specific activity of the radiolabel was 8 Ci/mmol. Plates were then incubated at room temperature for up to 50 minutes (dependant upon the period of linearity for the different enzyme species) before SPA beads, suspended to 1 mg/ml in a stop solution (200 mM Phosphoric Acid/NaOH pH 4, 750 mM MgCl2), were added in a volume of 40 ml.

Assay: Luciferase Assay: The stock cultures are grown, at 37° C. and under 5% CO2, in DMEM/F12 medium containing 10% FCS (fetal calf serum) and in each case split 1:10 after 2-3 days. Test cultures are seeded in 384-well plates with 2000 cells per well and grown at 37° C. for approx. 48 hours. The medium is then replaced with a physiological sodium chloride solution (130 mM sodium chloride, 5 mM potassium chloride, 2 mM calcium chloride, 20 mM HEPES, 1 mM magnesium chloride hexahydrate, 5 mM sodium bicarbonate, pH 7.4). The substances to be tested, which are dissolved in DMSO, are pipetted into the test cultures (maximum final concentration of DMSO in the test mixture: 0.5%) in a dilution series of from 5x10-11 M to 3x10-6 M (final concentration). 10 minutes later, forskolin is added to the A1 cells and all the cultures are subsequently incubated at 37° C. for four hours. After that, 35 ul of a solution which is composed of 50% lysis reagent (30 mM disodium hydrogenphosphate, 10% glycerol, 3% TritonX100, 25 mM TrisHCl, 2 mM dithiotreitol (DTT), pH 7.8) and 50% luciferase substrate solution (2.5 mM ATP, 0.5 mM luciferin, 0.1 mM coenzyme A, 10 mM tricine, 1.35 mM magnesium sulfate, 15 mM DTT, pH 7.8) are added to the test cultures, which are shaken for approx. 1 minute and the luciferase activity is measured using a camera system.
