Target: High affinity nerve growth factor receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P04629
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: 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: 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.

Assay: Radioligand Binding Assay: The composition of the binding assay buffer is determined in a course of detailed optimization procedure. This resulted in a binding assay buffer constituted by the following components: 25 mM Hepes (pH=7.4), 5 mM MgCl2, 1 mM CaCl2, 100 mM NaCl, supplemented with 0.1% of protease free BSA (as a final concentration). Competition binding assay is performed using 125I-CXCL10 (PerkinElmer, NEX348, specific activity 2200 Ci/mmol) radioligand in a final concentration of 50-70 pM. The nonspecific binding is defined by 150 pM of hr-CXCL10 (R&D Systems, Cat No 266-IP). The total assay volume is equal to 150 ul and contained 1% of DMSO (final concentration). Binding reaction is initiated by adding of membranes (10-20 ug proteins, approximately 5x105 cell equivalents) to the reaction mixture. After 60 minutes of incubation at 25° C. the reaction is terminated by rapid filtration over GF/B glass fibre filters that are pre-soaked with 0.5% polyethyleneimine (Fluka Analytical, P3143) for 1 hour, using a Skatron cell harvester device. Filters then are washed with 8 ml of ice-cold wash buffer (modified binding buffer in which BSA is omitted and the concentration of NaCl is adjusted to 500 mM concentration). The radioactivity retained on the filters is measured by a Wizard 1470 Automatic Gamma counter.

Assay: Radioligand Binding Assay: The composition of the binding assay buffer is determined in a course of detailed optimization procedure. This resulted in a binding assay buffer constituted by the following components: 25 mM Hepes (pH=7.4), 5 mM MgCl2, 1 mM CaCl2, 100 mM NaCl, supplemented with 0.1% of protease free BSA (as a final concentration). Competition binding assay is performed using 125I-CXCL10 (PerkinElmer, NEX348, specific activity 2200 Ci/mmol) radioligand in a final concentration of 50-70 pM. The nonspecific binding is defined by 150 pM of hr-CXCL10 (R&D Systems, Cat No 266-IP). The total assay volume is equal to 150 ul and contained 1% of DMSO (final concentration). Binding reaction is initiated by adding of membranes (10-20 ug proteins, approximately 5x105 cell equivalents) to the reaction mixture. After 60 minutes of incubation at 25° C. the reaction is terminated by rapid filtration over GF/B glass fibre filters that are pre-soaked with 0.5% polyethyleneimine (Fluka Analytical, P3143) for 1 hour, using a Skatron cell harvester device. Filters then are washed with 8 ml of ice-cold wash buffer (modified binding buffer in which BSA is omitted and the concentration of NaCl is adjusted to 500 mM concentration). The radioactivity retained on the filters is measured by a Wizard 1470 Automatic Gamma counter.

UniProt: P14416
Assay: Radioligand Binding Assay: Membranes prepared as above were resuspended to 1 ug protein/ul (measured by Bradford assay using BSA as standard), and 50 ul were added to each well of a polypropylene 96-well plate containing (per well): 50 ul of buffer (20 mM HEPES, 10 mM MgCl2, 1 mM EDTA, 1 mM EGTA, 100 mM N-methyl-D-gluconate, pH 7.4), 50 ul of 1.5 nM [3H]N-methylspiperone (final concentration 0.3 nM) and reference or D2 test ligand at various concentrations ranging from 50 uM to 50 uM (final concentrations ranging from 10 uM to 10 uM, triplicate determinations for each concentration of D2 test ligand). After a 1.5-hr incubation in the dark at room temperature, the reactions were harvested onto 0.3% PEI-soaked Filtermax GF/A filters (Wallac) and washed three times with ice-cold 50 mM Tris, pH 7.4 using a Perkin-Elmer Filtermate 96-well harvester. The filters were subsequently dried, placed on a hot plate (100° C.), and Melitilex-A (Wallac) scintillant was applied.

Assay: Functional Assay: HEK293 cells stably expressing canine TRPM8 were routinely grown as monolayers in Dulbecco's minimum essential medium supplemented with 10% FBS, 2 mM L-glutamine, 100 units/mL penicillin, 100 μg/mL streptomycin and 400 μg/mL G418. Cells were maintained in 5% CO2 at 37° C. At 24 hr prior to assay, cells were seeded in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) at a density of 5,000 cells per well in culture medium and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed, and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then incubated for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR™ or FDSS. Cells were treated with compounds of the formula (I) at varying concentrations and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to each well to achieve a final concentration that produces an approximately 80% maximal response.
