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: Fluorescence Polarization Assays: In another embodiment, Fluorescence Polarization ("FP") based assays may be used to detect and monitor ligand binding. Fluorescence polarization is a versatile laboratory technique for measuring equilibrium binding, nucleic acid hybridization, and enzymatic activity. Fluorescence polarization assays are homogeneous in that they do not require a separation step such as centrifugation, filtration, chromatography, precipitation, or electrophoresis. These assays are done in real time, directly in solution and do not require an immobilized phase. Polarization values can be measured repeatedly and after the addition of reagents since measuring the polarization is rapid and does not destroy the sample. Generally, this technique can be used to measure polarization values of fluorophores from low picomolar to micromolar levels.

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. See Caterina Trozzi et al., In Vitro Selection and Characterization of Hepatitis C Virus Serine Protease Variants Resistant to an Active-Site Peptide Inhibitor, 77(6) J. Virol. 3669 (2003).

Assay: Inhibition Assay: To initiate an assay, replicon cells were plated in the presence of a dilution series of test compound in the absence of G418. Typically, the assays were performed in a 96-well plate formate for manual operation, or a 384-well plate format for automated assay. Replicon cells and compound were incubated for 96 hours. At the end of the assay, cells were washed free of media and compound, and the cells were then lysed. RNA was quantified indirectly through detection of replicon-encoded NS3/4A protein levels, through an ELISA-based assay with an antibody specific for NS3/4A.

Assay: FRET-Based Assay: The HCV NS3 protease functions have been extensively studied and are considered as potential targets for antiviral therapy: see for example the many references listed in the introductory section of this application. Therefore, the activity of the compounds of the invention as anti-HCV agents was assessed using a full length HCV NS3 protease.The protease activity of the full length NS3/4a was measured using a FRET-based assay utilizing a peptide substrate derived from the NS4A/B cleavage site (Anaspec) and labelled at one end with a quencher (QXL520) and at the other with a fluorophore (5-FAMsp). NS3/4a (produced in-house by literature methods) was incubated with test compounds and peptide substrate in 50 mM Tris pH8, 20 mM DTT, 1% CHAPS, 10% glycerol and 5% DMSO. The reaction was followed by monitoring the change in fluorescence on a Molecular Devices Gemini plate reader for 30 minutes at room temperature.

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Enzyme Assay: 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 96-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 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate; on

Assay: Receptor Activity Assay: The disclosed compounds and compositions can be evaluated for their ability to act as a potentiator of metabotropic glutamate receptor activity, in particular mGluR4 activity, by any suitable known methodology known in the art. For example, Chinese Hamster Ovary (CHO) cells transfected with human mGluR4 or HEK cells co-transfected with rat mGluR4 and the G-protein regulated Inwardly Rectifying Potassium channel (GIRK) were plated in clear bottom assay plates for assay in a Hamamatsu FDSS Fluorometric Plate Reader. The cells were loaded with either a Ca2+-sensitive fluorescent dye or the thallium responsive dye and the plates were washed and placed into a suitable kinetic plate reader. For human mGluR4 assays, a fluorescence baseline was established for 3-5 seconds, the disclosed compounds were then added to the cells, and the response in cells was measured.

Target: Xaa-Pro aminopeptidase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O43895
Assay: Enzyme Assay: Human aminopeptidase P2 (APP2) enzyme activity was determined using the internally quenched fluorescent substrate: H-Lys(2-aminobenzoyl)-Pro-Pro-p-nitroanilide (Bachem, Torrance, Calif.) at 1 μM (=Km) for inhibitor studies and 5 μM for enzyme purification assays. The assay buffer was 0.1 M HEPES, pH 7.4, and the assay temperature was 30° C. Cleavage of the substrate by the enzyme produces an increase in fluorescence due to the release of H-Lys(2-aminobenzoyl). Enzyme rates were determined in an F. fluorescence plate reader (Molecular Devices, Sunnyvale, Calif.) using an excitation wavelength of 320 nm and an emission wavelength of 405 nm.
