Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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

Target: Lysophosphatidic acid receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q92633
Assay: In Vitro LPA1 Receptor Assay: Engagement of the LPA1 receptor by its ligand, oleoyl-L-α-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C.The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA1 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro. Approximately 10,000 cells in normal culture medium (Dulbecco's Modified Eagle Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom collagen coated 384 well plate (Beckton Dickinson). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1× Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake. To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 μM (diluted in assay buffer) were added to the assay wells and allowed to incubate for twenty five minutes. After incubation with test compounds the assay plate was placed in a FLIPR Tetra system (Molecular Devices) and LPA (diluted in assay buffer) was added to give a final concentration equivalent to its determined EC80 against LPA1 receptor. Ligand-dependent changes in intracellular calcium levels were determined by measuring changes in fluorescence of the dye over 515-575 nM following excitation over 470-495 nM.

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
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.

Assay: Enzyme Inhibition Assay: Measurements were performed using a modification of the scintillation proximity assay platform described previously by Georgopapadakou, N. H. et al. (22nd International Congress on Chemotherapy, 2001, Abstract P16.001). Compounds were solubilised in DMSO at a top concentration of 10 mM and serially diluted in half log steps to achieve a range of final assay concentrations of 100 uM to 1 nM. Compound at each concentration (100-fold final) was added to white 384 well plates in a volume of 0.5 ml. Human, A. fumigatus, T. brucei or L. major N-myristoyl transferase enzyme, dissolved to a working concentration of 10 nM in assay buffer (30 mM Tris/HCl pH 7.4, 0.5 mM EGTA, 0.5 mM EDTA, 1.25 mM DTT, 0.1% Triton X-100), was then added to columns 1 to 11 and 13 to 23 of the plates in a volume of 20 ml. To columns 12 and 24, 20 ml assay buffer was added to provide a no enzyme control. Following a 5 minute incubation at room temperature the substrates (GCGGSKVKPQPPQAK(Biotin)-Amide and myristoyl coenzyme A), dissolved in assay buffer, were added to all wells in a volume of 20 ml to start the reaction. The final concentrations of peptide and 3H-myristoyl coenzyme A were 0.5 mM and 125 nM respectively and the specific activity of the radiolabel was 8 Ci/mmol. Plates were then incubated at room temperature for up to 50 minutes (dependant upon the period of linearity for the different enzyme species) before SPA beads, suspended to 1 mg/ml in a stop solution (200 mM Phosphoric Acid/NaOH pH 4, 750 mM MgCl2), were added in a volume of 40 ml.

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).

Assay: In Vitro Inhibition Activity Assay: The compounds of formula I were tested for their activity on different PKC isoforms according to a published method (D. Geiges et al. Biochem. Pharmacol. 1997; 53:865-875) The assay is performed in a 96-well polypropylene microtiterplate (Costar 3794) that has been previously siliconized with Sigmacote (Sigma SL-2). The reaction mixture (50 μL) contains 10 μL of the relevant PKC isozyme together with 25 μL of the PKC inhibitor compound and 15 μL of a mix solution that contains 200 μg/mL protamine sulfate, 10 mM Mg(NO3)2, 10 μM ATP (Boehringer 519987) and 3750 Bq of 33P-ATP (Hartmann Analytic SFC301, 110 TBq/mmol) in 20 mM Tris-buffer pH 7.4+0.1% BSA. Incubation was performed for 15 minutes at 32° C. in a microtiterplate shaking incubator (Biolabo Scientific Instruments). Reaction was stopped by adding 10 μl of 0.5 M Na2EDTA, pH 7.4. 50 μl of mixture are pipetted onto a pre-wetted phosphocellulose paper (Whatmann 3698-915) under gentle pressure.

Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
Assay: Enzyme Assay: JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl2, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS.

Target: Protein deacetylase HDAC6 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9UBN7
Assay: Enzyme Assay: Enzyme activity of HDAC1,3 is determined using the substrate Ac-Lys-Tyr-Lys(Ac)-AMC while the enzyme activity of HDAC6 is assayed using the substrate Boc-lys(Ac)-AMC. The reaction is carried out in flat-bottom, 96-well, or 384-well microplates. After the substrate was deacetylated by HDACs, the product AMC which was obtained from hydrolysis by trypsin can generate fluorescence signal. Measurement is taken in using an multilabe plate reader a 355 nm excitation filter and a 460 nm emission filter. The initial rate of fluorescence should accurately reflect the rate of product formation and enzyme activity. Sample processing: The sample was dissolved in DMSO and kept at a low temperature. DMSO in the final system is limited under a low concentration which won't affect the enzyme activity.
