UniProt: P49674
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.

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease.

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.

Here, thrombin cleaves aminomethylcoumarin, which is measured fluorescently, from the peptic substrate. The determinations are carried out in microtitre plates.Substances to be tested are dissolved in various concentrations in dimethyl sulphoxide and incubated for 15 min with human thrombin (0.06 nmol/l dissolved in 50 mmol/l of Tris buffer [C,C,C-tris(hydroxymethyl)aminomethane], 100 mmol/l of sodium chloride, 0.1% BSA [bovine serum albumin], pH 7.4) at 22° C. The substrate (5 umol/l Boc-Asp(OBzl)-Pro-Arg-AMC from Bachem) is then added. After 30 min of incubation, the sample is excited at a wavelength of 360 nm and the emission is measured at 460 nm. The measured emissions of the test batches with test substance are compared to the control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide) and the IC50 values are calculated from the concentration/activity relationships.

Assay: AlphaScreen cAMP Assay: MIN6 cells [Miyazaki J et al. Endocrinology. 1990 July; 127(1):126-32] were stably transfected with an expression vector for human GPR119 cDNA (Acc. No. NP-848566). Min-6/hGPR119 cells are cultured in DMEM, 10% FBS, 50 uM beta-mercaptoethanol, 0.3 mg/mL Geniticin, 2 mM GlutaMAX at 37 C. 5% CO2. For the assay, the cells are placed in Optiplates (white, 384-well, 160W-barcoded, TC, sterile with lid, Cat. No. #6007688 (Perkin Elmer); 10000 cells/well; 50 ul). The plates covered with lids are then incubated for 24 hours at 37 C./5% CO2.After the medium has been sucked out of the wells completely, 10 ul of the test compound are added, the compounds are diluted beforehand with stimulating buffer (140 mM NaCl, 3.6 mM KCl, 0.5 mM NaH2PO4, 0.5 mM MgSO4, 1.5 mM CaCl2, 10 mM Hepes, 5 mM NaHCO3; pH 7.4. 0.5 mM IBMX and 0.1% BSA, the final DMSO concentration is 1%). After 45 minutes' incubation at RT, the cAMP concentrations are determined using the AlphaScreen cAMP Assay.

Assay: Inhibition Assay: [Experimental method]: Use Lance@Ultra Ulight™-TK assay kit from PerKinElmer to evaluate the inhibitory activity of compounds at KDR kinase. [Instrument]: PerKinElmer's ENVISION plate reader. [Materials]: Optiplate-384 well plate (PerKinElmer), kinase buffer (50 mM Hepes pH7.5, 0.25 mM EGTA, 2 mM DTT, 0.01% Tween 20, 10 mM Mg2+, 0.5 mM Mn2+), KDR kinase (790-1356 AA, Crown Bioscience), KDR kinase substrate (PerKinElmer catalogue # TRF0127-M), Lance@Eu-W1024-anti-phosphotyrosine (PT66) (PerKinElmer, catalogue #AD0068), ATP (Invitrogen), DMSO (Sigma, catalogue #34869), purified water (Millipore, type: Milli-Q). [Study conditions]: Mix KDR (final concentration: 20 nM) and compound (final DMSO: 0.5%), pre-incubate for 20 min at 30° C.; then add ATP (final concentration: 90 μM) and the substrate (final concentration 50 μM). React for 2 hrs at 30° C. After the reaction, add antibody and reaction for 60 min at 30° C. Read the plate (615 nm, 665 nm), calculate the ratio of the value at 665 nm vs 615 nm and analyze the data.

Assay: Spectrophotometric 384 Well Assay: Assay reactions are then carried out in 384-well plates, with hACC2 in an appropriate dilution and at final assay concentrations (f.c.) of 100 mM Tris (pH 7.5), 10 mM trisodium citrate, 25 mM KHCO3, 10 mM MgCl2, 0.5 mg/ml BSA, 3.75 mM reduced L-glutathione, 15 U/ml lactate dehydrogenase, 0.5 mM phosphoenolpyruvate, 15 U/ml pyruvate kinase, compounds at different concentrations at final DMSO concentrations of 1%.The enzymatic reaction is then started by addition of a mixture of NADH, acetyl Coenzyme A (both 2000 f.c.) and ATP (500 uM f.c.). The decrease of the optical density (slope S) is then determined at 25° C. at a wavelength of 340 nm over 15 minutes in a spectrophotometric reader.Each assay microtiter plate contains wells with vehicle instead of compound as controls for the non-inhibited enzyme (100% CTL; HIGH) and wells without acetyl-CoA as controls for non-specific NADH degradation (0% CTL; LOW).
