Target: Mu-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35372
Assay: Functional Assay (GTPgammaS Binding): The EC50 and Imax for mu opioid receptors was determined using a [I35S]GTPgammaS binding assay. This assay measures the functional properties of a compound by quantifying the level of G-protein activation following agonist binding in studies using stably transfected cells, and is considered to be a measure of the efficacy of a compound. Membranes from CHO (Chinese Hamster Ovary) cells that stably expressed the cloned human Mu opioid receptor were used in the experiments. Specifically, in a final volume of 0.5 mL, 12 different concentrations of each test compound were incubated with 7.5 ug of CHO cell membranes that stably expressed the human mu opioid receptor. The assay buffer consisted of 50 mM Tris-HCl, pH 7.4, 3 mM MgCl2, 0.2 mM EGTA, 3 uM GDP, and 100 mM NaCl. The final concentration of [35S]GTPgammaS was 0.080 nM. Nonspecific binding was measured by inclusion of 10 uM GTPgammaS. Binding was initiated by the addition of the membranes.

Assay: Cytochrome P450 Inhibition: Protocol 1: Studies were carried out in human liver microsomes. Human liver microsomes were purchased from BD Gentest. DMSO stocks were prepared for the test compounds. Aliquots of the DMSO solutions were diluted 1:3 by acetonitrile:ACN mixture (v/v: 40:60) to "400×" intermediate solutions, then further diluted by liver microsomes/buffer to "2×" intermediate solutions. "2×" intermediate solutions were mixed with "2×" NADPH/substrate solutions, which had been pre-warmed to 37° C. (final test compound concentrations were 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, 0.0136 μM, and 0 μM). The plates were kept in a 37° C. water bath for the duration of the experiment. At the end of incubation (5 minutes for 3A4; 45 minutes for 2C19; 10 minutes for 1A2, 2C9, 2D6), 120 μL of acetonitrile was added into corresponding wells. After the final time point was sampled, the plates were shaken at a vibrator (IKA, MTS 2/4) for 10 mM (600 rpm/min) and then centrifuged at 5594 g for 15 mM (Thermo Multifuge×3R). Aliquots of the supernatant were removed, diluted 1:1 into distilled water, and analyzed by LC-MS/MS. The peak area response ratio to internal standard (PARR) of the compounds at 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, and 0.0136 μM was compared to the PARR at 0 μM to determine the percent of metabolite generation from substrate at each test compound concentration.

Assay: Enzymatic Assay: Enzyme activities were determined kinetically in a final volume of 200 μl for 10 minutes at 37° C. by measuring the initial velocities of pNA release (405 nm) from the substrate using a Spectramax plus microtiterplate reader (Molecular devices). One unit of enzyme activity was defined as the amount of enzyme that catalyzes the release of 1 μmol pNA from the substrate per minute under assay conditions. The chromogenic substrate Gly-Pro-p-nitroanilide (100 μmol/l) was used at pH 8.3 for DPP IV, Lys-Ala-p-nitroanilide (1 mmol/l) at pH 5.5 for DPP II, Ala-Pro-p-nitroanilide (300 μmol/l) at pH 7.4 for DPP9 and Ala-Pro-p-nitroanilide (2 mmol/l) at pH 7.4 for FAP activity measurement. To evaluate the endopeptidase activity of FAP and the influence of inhibitors thereon, Z-Gly-Pro-AMC and Z-Gly-Pro-p-nitroanilide were used at a final concentration of 300 and 100 μmol/l, respectively. The substrate concentrations were chosen around the Km value obtained under the assay conditions used. Buffer compositions for the DPP assays were reported before in the purification articles−vide supra. The FAP assay buffer consisted of 50 mM Tris pH7.4 containing 100 mmol/l NaCl and 0.1 mg/ml bovine serum albumin. The PREP activity was measured as described by Brandt et al. using the chromogenic substrate Z-Gly-Pro-p-nitroanilide (0.25 mmol/l) at pH 7.5 in the presence of 10 mmol/l DTT. Test compounds were dissolved and diluted in DMSO (final concentration DMSO during assay 5% v/v) except for FAP where dilution of the inhibitor was done in water. Inhibitors are pre-incubated with the enzyme for 15 min at 37° C. before starting the assay by the addition of substrate. The concentration of enzyme and of inhibitor during the preincubation is double of the final concentration during activity measurement.

Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

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.)

Assay: MGAT LCMS Assay: The MGAT enzyme reactions were performed in CORNING Falcon 96-well Polypropylene plates, in a total volume of 60 uL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 uM 2-oleoylglycerol, 15 uM oleoyl-Coenzyme A and 0.0013 ug/uL Human or Mouse MGAT-2 or 0.0026 ug/uL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 uL of ice cold methanol containing 1 ug/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50x2.1 mm column, was used for the chromatography of enzyme products.

Assay: In Vitro JAK Kinase Assay: Compounds herein were tested for inhibitory activity of JAK targets according to the following in vitro assay described in Park et al., Analytical Biochemistry 1999, 269, 94-104. The catalytic domains of human JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a. 781-1124) with an N-terminal His tag were expressed using baculovirus in insect cells and purified. 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.
