Assay: Kinase Activity Assay (NADH Read-Out): Recombinant human c-Met protein (Invitrogen, Carlsbad, Calif., USA) is used. As substrate for the kinase reaction the peptide KKKSPGEYVNIEFG (JPT, Germany) is used. For the assay, 1 μL of a 51-fold concentrated solution of the test compound in DMSO is pipetted into a white 384-well microtiter plate (Greiner Bio-One, Frickenhausen, Germany). 25 μL of a solution of c-Met (final concentration 30 nM) and pyruvate kinase/lactate dehydrogenase (Roche Diagnostics, Mannheim, Germany; final concentration 8 mg/L) in assay buffer [3-(N-morpholino)propanesulfonic acid (MOPS), 50 mM, pH 7; MgCl2, 10 mM; bovine serum albumin (BSA), 0.01%; Triton X 100, 0.01%; DTT, 2 mM] are added, and the mixture is incubated for 5 min at room temperature. Then, the kinase reaction is started by the addition of 25 μL of a solution of adenosine triphosphate (ATP, final concentration 30 μM), substrate (final concentration 100 μM), nicotinamide adenine dinucleo-tide (NADH, final concentration 50 μM) and dithiothreitol (DTT, final concentration 2 mM) in assay buffer, and the resulting mixture is incubated for a reaction time of 100 min at 32° C. Subsequently, the amount of phosphorylated substrate is evaluated by measurement of the decrease of NADH fluorescence. Therefore, the fluorescence emissions at 465 nm after excitation at 340 nm is measured in a fluorescence reader, e.g. Tecan Ultra (Tecan, Männedorf, Switzerland).

Assay: Inhibition Assay: To measure inhibition of the enzymatic activity of the HCV NS5B RNA-dependent RNA polymerase by the nucleoside triphosphate compounds of the present invention, a radiolabeled nucleotide incorporation assay was used. This assay is a modified version of the assay described in International Publication No. WO2002/057287. Briefly, 50 uL reactions containing 20 mM HEPES (pH 7.3); 7.5 mM DTT; 20 units/ml RNasIN; 1 uM each of ATP, GTP, UTP and CTP; 20 uCi/mL [33P]-CTP; 10 mM MgCl; 60 mM NaCl; 100 ug/ml BSA; 0.021 uM DCoH heteropolymer RNA template; and 5 nM NS5B (1b-BKΔ55) enzyme were incubated at room temperature for 1 hour. The assay was then terminated by the addition of 500 mM EDTA (50 uL). The reaction mixture was transferred to a Millipore DE81 filter plate and the incorporation of labeled CTP is determined using Packard TopCount. Compound IC50 values can then be calculated from experiments with 10 serial 3-fold dilutions of the inhibitor in duplicate. The intrinsic potency (Ki) of an NTP inhibitor is derived from its NS5B IC50 using the Cheng-Prusoff equation for a competitive inhibitor, as described in Cheng et al., Biochem Pharmacol 22:3099-3108 (1973): Ki=IC50/(1+[S]/Km), where [S]=1 uM, and Km is the concentration of cognate NTP yielding half-maximal enzyme activity in the assay absent exogenous inhibitors.

Assay: Enzymatic Screening Assay: The enzymatic test is a test in two steps.In a first step, it consists in placing in contact the compound according to the invention, the dialysed MetAP2 protein and the substrate (Met-Pro-Arg-pNa peptide synthesized by Neosystem), the N-terminal methionine of which can be cleaved with MetAP2, and which bears at the C-terminal end a para-nitroaniline (pNa) chromophore, which can itself be released by another peptidase only when the N-terminal methionine has been cleaved beforehand.Consequently, the second step consists in reacting the peptides cleaved in the preceding step with a second peptidase in order to release the chromophore. The peptidase used in this second step is cathepsin, which comes from the TagZyme DAPase kit (Quiagen, 34366).The MetAP2 activity is proportional to the amount of para-nitroaniline released, which is measured by absorbance at 405 nm.

Assay: Cell Based Assay: TRKA co-expressed with p75: The assays are based upon DiscoveRx's proprietary Enzyme Fragment Complementation (EFC) technology. In the case of the TRK cell lines, the enzyme acceptor (EA) protein is fused to a SH2 protein and the TRK receptor of interest has been tagged with a Prolink tag. Cryopreserved PathHunter cells are used from either in-house produced batches or bulk batches bought directly from DiscoveRx. Cryopreserved cells are resuscitated, spun 1000 rpm for 4 min to remove freezing media, and resuspended in MEM+0.5% horse serum (both Invitrogen) to 5e^5 cells/ml. The cells are then plated using a Multidrop into Greiner white tissue culture treated plates at 20 μl/well and incubated for 24 h at 37 °C., 5% CO2, high humidity. On the day of the assay, the cell plates are allowed to cool to room temperature for 30 min prior to the assay. 4 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

Assay: Enzymatic Screening Assay: The enzymatic test is a test in two steps.In a first step, it consists in placing in contact the compound according to the invention, the dialysed MetAP2 protein and the substrate (Met-Pro-Arg-pNa peptide synthesized by Neosystem), the N-terminal methionine of which can be cleaved with MetAP2, and which bears at the C-terminal end a para-nitroaniline (pNa) chromophore, which can itself be released by another peptidase only when the N-terminal methionine has been cleaved beforehand.Consequently, the second step consists in reacting the peptides cleaved in the preceding step with a second peptidase in order to release the chromophore. The peptidase used in this second step is cathepsin, which comes from the TagZyme DAPase kit (Quiagen, 34366).The MetAP2 activity is proportional to the amount of para-nitroaniline released, which is measured by absorbance at 405 nm.

Assay: Radioligand Binding Assay: Radioligand binding was performed using filtration or scintillation proximity assay (SPA) technology. SPA assays were done at room temperature in 10 mM HEPES pH 7.4, 1 mM EDTA containing 2 mM MnCl2 and 16 nM [3H]-PGD2 (PerkinElmer, Waltham, Mass.) (164 Ci mmol-1), in a final volume of 0.05 mL. Competing ligands were diluted in dimethylsulfoxide and added using very low volumes (500 nL). The reaction was initiated by the addition of a mixture of 3.52 ug of membrane protein prepared from a human embryonic kidney (HEK)-hCRTH2 cell line adhered to 140 ug of wheatgerm agglutinin SPA beads (PerkinElmer). Total and non-specific binding were determined in the absence and the presence of a CRTH2 antagonist, respectively. The reaction was routinely conducted for 60 minutes at room temperature followed by centrifugation for 5 minutes at 1000 RPM. The radioactivity was measured with a TopCountNXT (PerkinElmer). Filtration binding assays were done in a similar way with minor differences. The assay volume was 0.20 mL and competing ligands in dimethylsulfoxide were added in 2 uL. [3H]-PGD2 was used at 0.6 nM, and reactions were initiated by the addition of 10 ug of membrane protein. Reactions were terminated by filtration through GF/C filter plates (PerkinElmer) presoaked in 10 mM HEPES. After washing with buffer, plates were dried in a 50° C. oven for 1 h, scintillation cocktail was added and radioactivity was measured. Results determined using the SPA-based assay were similar to those from the filtration binding assay.

Assay: Biochemical Kinase Assay: Liquid handling and incubation steps were done on an Innovadyne Nanodrop Express equipped with a robotic arm (Thermo CatX, Caliper Twister II) and an incubator (Liconic STX40, Thermo Cytomat 2C450). The assay plates were prepared by addition of 50 nl per well of compound solution in 90% DMSO. The kinase reactions were started by stepwise addition of 4.5 ul per well of peptide/ATP-solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 16 mM MgCl2, 1122 uM ATP, 4 uM peptide (5-Fluo-Ahx-KKKKEEIYFFFG-NH2, Biosyntan GmbH) and 4.5 ul per well of enzyme solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 16 mM MgCl2, 6 nM FGFR4 (GST-FGFR4(388-802), produced in-house by expression in insect cells and affinity chromatography). Kinase reactions were incubated at 30° C. for 60 minutes and subsequently terminated by addition of 16 ul per well of stop solution (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35).

Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
Assay: JAK Enzyme Assay: The activity of the isolated recombinant JAK1 and JAK2 kinase domain was measured by monitoring phosphorylation of a peptide derived from JAK3 (Val-Ala-Leu-Val-Asp-Gly-Tyr-Phe-Arg-Leu-Thr-Thr, fluorescently labeled on the N-terminus with 5-carboxyfluorescein) using the Caliper LabChip® technology (Caliper Life Sciences, Hopkinton, Mass.). To determine inhibition constants (Ki), compounds were diluted serially in DMSO and added to 50 μL kinase reactions containing purified enzyme (1.5 nM JAK1, or 0.2 nM JAK2), 100 mM HEPES buffer (pH 7.2), 0.015% Brij-35, 1.5 μM peptide substrate, ATP (25 μM), 10 mM MgCl2, 4 mM DTT at a final DMSO concentration of 2%. Reactions were incubated at 22° C. in 384-well polypropylene microtiter plates for 30 minutes and then stopped by addition of 25 μL of an EDTA containing solution (100 mM HEPES buffer (pH 7.2), 0.015% Brij-35, 150 mM EDTA), resulting in a final EDTA concentration of 50 mM. After termination of the kinase reaction, the proportion of phosphorylated product was determined as a fraction of total peptide substrate using the Caliper LabChip® 3000 according to the manufacturer's specifications.

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. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).
