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: Scintillation Proximity Assay: The human PDE10A full length assay was performed in 96-well micro titer plates. The reaction mixture of 50 μl contained 20 mM HEPES pH=7.5/10 mM MgCl2/0.05 mg/ml BSA (Sigma cat. # A-7906), 50 nM cGMP (Sigma, cat. # G6129) and 50 nM [3H]-cGMP (GE Healthcare, cat. # TRK392 S.A. 13.2 Ci/mmol), 3.75 ng/well PDE10A enzyme (Enzo Life Science, Lausen, Switzerland cat # SE-534) with or without a specific test compound. A range of concentrations of the potential inhibitor was used to generate data for calculating the concentration of inhibitor resulting in 50% of the effect (e.g. IC50, the concentration of the competitor inhibiting PDE10A activity by 50%). Non-specific activity was tested without the enzyme. The reaction was initiated by the addition of the substrate solution (cGMP and [3H]-cGMP) and allowed to progress for 20 minutes at room temperature. The reaction was terminated by adding 25 μl of YSi-SPA scintillation beads (GE Healthcare, cat. # RPNQ0150) in 18 mM zinc sulphate solution (stop reagent). After 1 h under shaking, the plate was centrifuged one minute at 170 g to allow beads to settle. Afterwards, radioactive counts were measured on a Perkin Elmer Top-Count Scintillation plate reader.

UniProt: P33981
Assay: Kinase Assay: For the assay 50 nL of a 100-fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 μl of a solution of Mps-1 in assay buffer [0.1 mM sodium-ortho-vanadate, 10 mM MgCl2, 2 mM DTT, 25 mM Hepes pH 7.7, 0.05% BSA, 0.001% Pluronic F-127] were added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to Mps-1 before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 μl of a solution of 16.7 adenosine-tri-phosphate (ATP, 16.7 μM=>final conc. in the 5 μl assay volume is 10 μM) and peptide substrate (1.67 μM=>final conc. in the 5 μl assay volume is 1 μM) in assay buffer and the resulting mixture was incubated for a reaction time of 60 min at 22° C. The concentration of Mps-1 in the assay was adjusted to the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical enzyme concentrations were in the range of about 1 nM (final conc. in the 5 μl assay volume). The reaction was stopped by the addition of 3 μl of a solution of HTRF detection reagents (100 mM Hepes pH 7.4, 0.1% BSA, 40 mM EDTA, 140 nM Streptavidin-XLent [#61GSTXLB, Fa. Cis Biointernational, Marcoule, France], 1.5 nM anti-phospho(Ser/Thr)-Europium-antibody [#AD0180, Perkin Elmer LAS, Rodgau-Jügesheinn, Germany]. The resulting mixture was incubated 1 h at 22° C. to allow the binding of the phosphorylated peptide to the anti-phospho(Ser/Thr)-Europium-antibody. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Europium-labelled anti-phospho(Ser/Thr) antibody to the Streptavidin-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a Viewlux TR-FRET reader (PerkinElmer LAS, Rodgau-Jügesheinn, Germany).

Assay: ThermoFluor® Assay: ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Discovery, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation. Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1 °C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >60D cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1x=46 mL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

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.

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 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 μM. A reference compound was included on each assay plate in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The final buffer conditions were as follows: 60 mM Hepes, pH 7.0, 0.05% BSA, 2 mM DTT. Incubations were carried out at RT (22° C.) for 2 h for Pim-1, 1 hour and 30 min for Pim-3, and 45 min for Pim-2. The reaction was stopped by the addition of 3 mM EDTA, and fluorescence was measured by an HTRF® Rubystar microplate reader.

Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.
