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.

Assay: Radioligand Binding Assay: HEK-293 cells stably expressing mouse TAAR1 were maintained at 37° C. and 5% CO2 in DMEM high glucose medium, containing fetal calf serum (10%, heat inactivated for 30 min at 56° C.), penicillin/streptomycin (1%), and 375 ug/ml geneticin (Gibco). Cells were released from culture flasks using trypsin/EDTA, harvested, washed twice with ice-cold PBS (without Ca2+ and Mg2+), pelleted at 1,000 rpm for 5 min at 4° C., frozen and stored at -80° C. Frozen pellets were suspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 10 mM EDTA and homogenized with a Polytron (PT 6000, Kinematica) at 14,000 rpm for 20 s. The homogenate was centrifuged at 48,000Ã¿g for 30 min at 4° C. Subsequently, the supernatant was removed and discarded, and the pellet resuspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 0.1 mM EDTA using the Polytron (20 s at 14,000 rpm). This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at -80° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 uM unlabeled ligand. All compounds were tested at a broad range of concentrations (10 pM to 10 uM) in duplicates. The test compounds (20 ul/well) were transferred into a 96 deep well plate (TreffLab), and 180 ul of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 ul of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3xKd in nM and 500 ul of the membranes (resuspended at 50 ug protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer. After addition of 45 ul of Microscint 40 (PerkinElmer) the Unifilter-96 plate was sealed and after 1 hr the ratioactivity counted using a TopCount Microplate Scintillation Counter (Packard Instrument Company).

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: MKNK1 Kinase Assay: For the assay 50 mL 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 MKNK1 in aqueous assay buffer [50 mM HEPES pH 7.5, 5 mM magnesium chloride, 1.0 mM dithiothreitol, 0.005% (v/v) Nonidet-P40 (Sigma)] was added and the mixture was incubated for 15 min at 22 °C. to allow pre-binding of the test compounds to the enzyme before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 μL of a solution of adenosine-tri-phosphate (ATP, 16.7 μM=>final conc. in the 5 μL assay volume is 10 μM) and substrate (0.1 μM=>final conc. in the 5 μL assay volume is 0.06 μM) in assay buffer and the resulting mixture was incubated for a reaction time of 45 min at 22 °C. The concentration of MKNK1 was adjusted depending of the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical concentrations were in the range of 0.05 μg/ml. The reaction was stopped by the addition of 5 μL of a solution of TR-FRET detection reagents (5 nM streptavidine-XL665 [Cisbio Bioassays, Codolet, France] and 1 nM anti-ribosomal protein S6 (pSer236)-antibody from Invitrogen [#44921G] and 1 nM LANCE EU-W1024 labeled ProteinG [Perkin-Elmer, product no. AD0071]) in an aqueous EDTA-solution (100 mM EDTA, 0.1% (w/v) bovine serum albumin in 50 mM HEPES pH 7.5). The resulting mixture was incubated for 1 h at 22 °C. to allow the formation of complex between the phosphorylated biotinylated peptide and the detection reagents. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Eu-chelate to the streptavidine-XL. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm were measured in a TR-FRET reader, e.g. a Rubystar (BMG Labtechnologies, Offenburg, Germany) or a Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and at 622 nm was taken as the measure for the amount of phosphorylated substrate.

Assay: In Vitro ATP-33P Casein Assay: "U"-bottomed Falcon plates are prepared by placing 5 uL of solutions of the compounds according to the invention at concentrations of 10, 1, 0.1, 0.01 or 0.001 uM in different wells. The solutions of the compounds according to the invention at these various concentrations are prepared by diluting in a test buffer (Tris 50 mM pH 7.5, MgCl2 10 M, DTT 2 mM and EGTA 1 mM) a stock solution in DMSO at a concentration of 10 mM. Next, 5 uL of dephosphorylated casein are added to a final concentration of 0.2 ug/uL, 20 uL of CK1 epsilon to a final concentration of 3 ng/uL, and 20 uL of ATP-33P to a final concentration of 0.02 uCi/uL mixed with cold ATP (10 uM final approximately 2x106 CPM per well). The final total test volume per well is equal to 50 uL. The "U"-bottomed Falcon test plate mentioned above is vortexed, and then incubated at room temperature for 2 hours. After 2 hours the reaction is stopped by adding an ice-cold solution of 65 uL of cold ATP (2 mM) prepared in test buffer. 100 uL of the reaction mixture are then transferred from the "U"-bottomed Falcon plate into Millipore MAPH filter plates, preimpregnated with 25 uL of ice-cold 100% TCA. The Millipore MAPH filter plates are agitated gently and are left to stand at room temperature for at least 30 minutes to precipitate the proteins. After 30 minutes, the filter plates are sequentially washed and filtered with 2x150 uL of 20% TCA, 2x150 uL of 10% TCA and 2x150 uL of 5% TCA (6 washes in total per plate/900 uL per well). The plates are left to dry overnight at room temperature. Next, 40 uL of Microscint-20 Packard scintillation liquid are added per well and the plates are closed in a leaktight manner. The radiation emitted by each well is then measured for 2 minutes in a TopCount NXT Packard scintillation counter, in which the values of CPM/well are measured.

Assay: IMAP-FP Assay: Activated ERK2 activity was determined in an IMAP-FP assay (Molecular Devices). Using this assay format, the potency (IC50) of each compound was determined from a 10 point (1:3 serial dilution, 3 uM starting compound concentration) titration curve using the following outlined procedure. To each well of a black Corning 384-well plate (Corning Catalog #3575), 7.5 nL of compound (3333 fold dilution in final assay volume of 25 uL) was dispensed, followed by the addition of 15 uL of kinase buffer (tween containing kinase buffer, Molecular Devices) containing 0.0364 ng/mL (0.833 nM) of phosphorylated active hERK2 enzyme. Following a 15 minute compound & enzyme incubation, each reaction was initiated by the addition of 10 uL kinase buffer containing 2.45 uM ERK2 IMAP substrate peptides (2.25 uM-unlabeled IPTTPITTTYFFFK-COOH and 200 nM-labeled IPTTPITTTYFFFK-SFAM (5-carboxyfluorescein)-COOH), and 75 uM ATP.
