Assay: TR-FRET Assay: TR-FRET assay for retinol-induced RBP4-TTR interaction Binding of a desired RBP4 antagonist displaces retinol and induces hindrance for RBP4-TTR interaction resulting in the decreased FRET signal (FIG. 7). Bacterially expressed MBP-RBP4 and untagged TTR were used in this assay. For the use in the TR-FRET assay the maltose binding protein (MBP)-tagged human RBP4 fragment (amino acids 19-201) was expressed in the Gold(DE3)pLysS E. coli strain (Stratagene) using the pMAL-c4x vector. Following cell lysis, recombinant RBP4 was purified from the soluble fraction using the ACTA FPLC system (GE Healthcare) equipped with the 5-ml the MBP Trap HP column. Human untagged TTR was purchased from Calbiochem. Untagged TTR was labeled directly with Eu3+ Cryptate-NHS using the HTRF Cryptate Labeling kit from CisBio following the manufacturer's recommendations. HTRF assay was performed in white low volume 384 well plates (Greiner-Bio) in a final assay volume of 16 ul per well. The reaction buffer contained 10 mM Tris-HCl pH 7.5, 1 mM DTT, 0.05% NP-40, 0.05% Prionex, 6% glycerol, and 400 mM KF. Each reaction contained 60 nM MBP-RBP4 and 2 nM TTR-Eu along with 26.7 nM of anti-MBP antibody conjugated with d2 (Cisbio). Titration of test compounds in this assay was conducted in the presence of 1 uM retinol. All reactions were assembled in the dark under dim red light and incubated overnight at +4° C. wrapped in aluminum foil. TR-FRET signal was measured in the SpectraMax M5e Multimode Plate Reader (Molecular Device). Fluorescence was excited at 337 nm and two readings per well were taken: Reading 1 for time-gated energy transfer from Eu(K) to d2 (337 nm excitation, 668 nm emission, counting delay 75 microseconds, counting window 100 microseconds) and Reading 2 for Eu(K) time-gated fluorescence (337 nm excitation, 620 nm emission, counting delay 400 microseconds, counting window 400 microseconds).

UniProt: O00329
Assay: Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The activities were measured using a time-resolved fluorescence resonance energy transfer (TR-FRET) assay. TR-FRET monitored the formation of 3,4,5-inositol triphosphate molecule that competed with fluorescently labeled PIP3 for binding to the GRP-1 pleckstrin homology domain protein. An increase in phosphatidylinositide 3-phosphate product resulted in a decrease in TR-FRET signal as the labeled fluorophore was displaced from the GRP-1 protein binding site. Class I PI3K isoforms were expressed and purified as heterodimeric recombinant proteins. All assay reagents and buffers for the TR-FRET assay were purchased from Millipore. PI3K isoforms were assayed under initial rate conditions in the presence of 25 mM Hepes (pH 7.4), and 2xKm ATP (75-500 uM), 2 uM PIP2, 5% glycerol, 5 mM MgCl2, 50 mM NaCl, 0.05% (v/v) Chaps, 1 mM dithiothreitol, and 1% (v/v) DMSO at the following concentrations for each isoform: PI3Kα, PI3Kβ, and PI3Kδ between 25 and 50 uM, and PI3Kγ at 2 nM. The compounds of Table 1 and Compound X ((S)-2,4-diamino-6-((1-(5-chloro-4-oxo-3-(pyridin-3-yl)-3,4-dihydroquinazolin-2-yl)ethyl)amino)pyrimidine-5-carbonitrile) and Compound Y ((S)-2,4-diamino-6-((1-(5-chloro-4-oxo-3-(pyridin-3-yl)-3,4-dihydroquinazolin-2-yl)ethyl)amino)pyrimidine-5-carbonitrile) were added to the assay solution and incubated for 30 minutes at 25° C. The reactions were terminated with a final concentration of 10 mM EDTA, 10 nM labeled-PIP3, and 35 nM Europium labeled GRP-1 detector protein before reading TR-FRET on an Envision plate reader (Ex: 340 nm; Em: 615/665 nm; 100 us delay and 500 us read window). The results were normalized based on positive (1 uM wortmanin) and negative (DMSO) controls, and the IC50 values for PI3K α, β, δ and γ were calculated from the fit of the dose-response curves to a four-parameter equation.

Assay: Radioligand Binding Assay: HEK-293 cells stably expressing rat 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).

UniProt: O14649
Assay: Activity Assay: Human TASK-1 channels were expressed in Xenopus oocytes. For this purpose, oocytes were isolated from Xenopus laevis and defoliculated. Subsequently, TASK-1-encoding RNA synthesized in vitro was injected into the oocytes. After two days of TASK-1 protein expression, TASK-1 currents were measured by two-microelectrode voltage clamp. Data were acquired and analyzed using a TEC-10cx amplifier (NPI Electronic, Tamm, Germany) connected to an ITC-16 interface (Instrutech Corp., Long island, USA) and Pulse software (HEKA Elektronik, Lambrecht, Germany). Oocytes were clamped to −90 mV and TASK-1 mediated currents were measured during 500 ms voltage pulses to 40 mV. Oocytes were continuously superfused with ND96 buffer containing 98 mM sodium chloride, 2 mM potassium chloride, 1.8 mM calcium chloride, 1 mM magnesium chloride, 5 mM 4-(2-hydroxyethyl)-piperazine-1-ethanesulfonic acid (HEPES: pH adjusted to 7.4 with sodium hydroxide). All experiments were performed at room temperature. Test compounds were consecutively added to the bath solution at rising concentrations.

Target: ALK tyrosine kinase receptor (SINGLE PROTEIN), Homo sapiens
UniProt: Q9UM73
Assay: ELISA-Based In Vitro Kinase Assay: GST-tagged recombinant wild-type or L1196M mutated ALK kinase (rALK) was expressed in Sf9 insect cells using the pBacPAK baculovirus vector system (Clontech) and purified using Glutathione Sepharose 4B affinity beads (GE Healthcare). Recombinant 3C protease was used to remove the GST tag. Purified ALK was used to screen inhibitors in the ELISA-based kinase assay, as follows: Nunc-Immuno 96-well plates were incubated overnight at 30° C. with coating solution containing 2 μg of a specific ALK peptide substrate (ARDIYRASFFRKGGCAMLPVK) in PBS. Wells were then washed with 200 μL of wash buffer (PBS-Tween 0.05%) and incubated with 4% BSA in PBS for at least 2 h at 30° C. The kinase reaction was performed in the presence of 50 mM Tris pH 7.5, 5 mM MnCl2, 5 mM MgCl2, 0.3 mM ATP and purified rALK in a total volume of 100 μL/well at 30° C. for 15 min. For inhibitor testing the reaction mix was preincubated with inhibitor or vehicle for 10 min at room temperature before transferring to the ELISA plate. After the reaction, the wells were washed 5 times with 200 μL of wash buffer. Phosphorylated peptide was detected using 100 μL/well of a mouse monoclonal anti-phosphotyrosine antibody (clone 4G10 UpstateBiotech Ltd) diluted 1:2000 in PBS+4% BSA. After 30 min incubation at room temperature the antibody was removed and wells were washed as described above. 100 μL of a secondary antibody (anti-mouse IgG, Horseradish Peroxidase linked whole antibody, Amersham Pharmacia Biotech) diluted 1:1000 in PBS+4% BSA was added to each well and the plate was incubated again for 30 min at room temperature before washing as above. The plate was developed using 100 μL/well TMB Substrate Solution (Pierce) and the reaction was stopped by adding an equal volume of 1M H2SO4. Finally, the absorbance was read at 450 nm using an ELISA plate reader (Bio-Rad).

Target: Phosphatidylinositol 3-kinase regulatory subunit alpha (SINGLE PROTEIN), Homo sapiens
UniProt: P27986
Assay: Enzyme Assay: The test uses a lucifeurerin/luciferase system to measure the concentration of ATP and its consumption during the enzymatic reaction. The test is performed in 96-well format (Corning/Costar 96 black flat-bottomed half-wells plate, ref. 3694) in a total volume of 30 μl. To 1 μl of inhibitor in 100% DMSO are added (final concentrations) 50 μM of the substrate PIP2 ((L-α-phosphatidyl-D-myoinositol 4,5-bisphosphate, Echelon 117P-4516-0500), 2 μM of ATP and 1.7 μg/ml of PI3Kα, (p110α/p85α, Invitrogen PV4788) in a buffer of Tris/HCl 50 mM pH 7.5, EGTA 1 mM, MgCl2 10 mM, Chaps 0.03%, 1 mM DTT). After 90 minutes, the reaction is quenched by adding 20 μl/well of KinaseGlo reagent (Promega V6713). After 10 minutes in the dark, the luminescence is read on the PHERAStar microplate reader (reading at 0.8 sec/well).
