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

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.

Assay: Caliper Assay: All assays were performed in 384-well microtiter plates. Each assay plate contained 8-point serial dilutions for 40 test compounds, as well as four 8-point serial dilutions of staurosporine as a reference compound, plus 16 high and 16 low controls. Liquid handling and incubation steps were done on a Thermo CatX workstation equipped with Innovadyne Nanodrop Express. Between pipetting steps, tips were cleaned in wash cycles using wash buffer. The assay plates were prepared by addition of 50 nL per well of compound solution in 90% DMSO. The kinase reactions were started by stepwise addition of 4.5 μL per well of peptide/ATP-solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 μM sodium orthovanadate, 20 mM MgCl2, 2 mM MnCl2, 4 μM ATP, 4 μM peptide (FITC-Ahx-EAIYAAPFAKKK-NH2)) and 4.5 μL per well of enzyme solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 μM sodium orthovanadate, 20 mM MgCl2, 2 mM MnCl2, 3.5 nM ABL (ABL(64-515), produced in-house from E. coli)). Kinase reactions were incubated at 30 °C. for 60 minutes and subsequently terminated by addition of 16 μL per well of stop solution (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35). Plates with terminated kinase reactions were transferred to the Caliper LC3000 workstations for reading. Phosphorylated and unphosphorylated peptides were separated using the Caliper microfluidic mobility shift technology. Briefly, samples from terminated kinase reactions were applied to the chip. Analytes are transported through the chip by constant buffer flow and the migration of the substrate peptide is monitored by the fluorescence signal of its label. Phosphorylated peptide (product) and unphosphorylated peptide (substrate) are separated in an electric field by their charge/mass ratio.

Assay: HTRF FRET Assay: A homogeneous time-resolved FRET assay can be used to determine IC50 values for inhibitors of the soluble human BACE1 catalytic domain. This assay monitors the increase of 620 nm fluorescence that resulted from BACE1 cleavage of an APPswedish APPswe mutant peptide FRET substrate (QSY7-EISEVNLDAEFC-Europium-amide). This substrate contains an N-terminal QSY7 moiety that serves as a quencher of the C-terminal Europium fluorophore (620 nm Em). In the absence of enzyme activity, 620 nm fluorescence is low in the assay and increased linearly over 3 hours in the presence of uninhibited BACE1 enzyme Inhibition of BACE1 cleavage of the QSY7-APPswe-Eu substrate by inhibitors is manifested as a suppression of 620 nm fluorescence.Varying concentrations of inhibitors at 3x the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 ul) for 30 minutes at 30° C. in reaction buffer containing 20 mM Na-Acetate pH 5.0, 10% glycerol.

UniProt: O43614
Assay: Antagonistic Activity Assay: The antagonistic activities of the test compounds on human orexin-1 receptor (hOX1R) and orexin-2 receptor (hOX2R) were measured by modifying from the method described in literature (Toshikatsu Okumura et al., Biochemical and Biophysical Research Communications 280, 976-981, 2001). Chinese hamster ovary (CHO) cells forcibly expressing the hOX1R and hOX2R were seeded into a 96 well Black clear bottom plate (Nunc) at 20,000 cells per well, which were cultured in Ham's F-12 medium containing 0.1 mM MEM non-essential amino acids, 0.5 mg/ml G418, 10% fetal bovine serum (all by Invitrogen) for 16 hours under the conditions of 37° C., 5% CO2. After removing the medium, 100 uL of 0.5 uM Fluo-4AM ester (Dojin) in an assay buffer (25 mM HEPES (Dojin), Hank's balanced salt solution (Invitrogen), 0.1% bovine serum albumin, 2.5 mM probenecid, 200 ug/ml Amaranth (all by Sigma-Aldrich), pH 7.4) was added and the cells were incubated for 60 minutes at 37° C., 5% CO2. After removing the medium, 100 uL of 0.5 uM Fluo-4AM ester (Dojin) in an assay buffer (25 mM HEPES (Dojin), Hank's balanced salt solution (Invitrogen), 0.1% bovine serum albumin, 2.5 mM probenecid, 200 ug/ml Amaranth (all by Sigma-Aldrich), pH 7.4) was added and the cells were incubated for 60 minutes at 37° C., 5% CO2. After removing the assay buffer containing fluo-3AM ester, the test compound was dissolved in dimethyl sulfoxide to be 10 mM and diluted with the assay buffer, 150 uL of which was added and incubated for 30 minutes.
