Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
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 384-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 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

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).

The catalytic activity of JAK1, JAK2 or JAK3 was assayed by measuring the phosphorylation of a biotinylated peptide. The phosphorylated peptide was detected by homogenous time resolved fluorescence (HTRF). IC50s of compounds were measured for each kinase in the 40 microL reactions that contain the enzyme, ATP and 500 nM peptide in 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL (0.01%) BSA. For the 1 mM IC50 measurements, ATP concentration in the reactions was 1 mM. Reactions were carried out at room temperature for 1 hr and then stopped with 20 μL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20 in assay buffer (Perkin Elmer, Boston, Mass.). Binding to the Europium labeled antibody took place for 40 minutes and HTRF signal was measured on a Fusion plate reader (Perkin Elmer, Boston, Mass.).

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
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

UniProt: P48730
Assay: Kinase Assay: The kinase assay was performed in V-bottom 384-well plates. The final assay volume was 30 ul prepared from 15 ul additions of enzyme, substrates (fluoresceinated peptide FL-AHA-KRRRAL-PSER-VASLPGL-OH and ATP) and test compounds in assay buffer (20 mM HEPES pH 7.4, 30 mM MgCl2, 0.015% Brij35 and 4 mM DTT). The reaction was incubated at room temperature for 22 hours and terminated by adding 45 ul of 35 mM EDTA to each sample. The reaction mixture was analyzed on the Caliper LABCHIPÂ®3000 (Caliper, Hopkinton, Mass.) by electrophoretic separation of the unphosphorylated substrate and phosphorylated product Inhibition data were calculated by comparison of the no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentration of reagents in the assay were 200 pM CK1ε or CK1δ, 50 uM ATP, 1.5 uM FL-AHA-KRRRAL-PSER-VASLPGL-OH, and 1.6% DMSO. Dose response curves were generated to determine the concentration required to inhibit 50% of the kinase activity (IC50). Compounds were dissolved at 10 mM in dimethylsulfoxide (DMSO) and evaluated at eleven concentrations. IC50 values were derived by non-linear regression analysis.
