Target: Glucocorticoid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P04150
Assay: GRE Agonist Assay: A reporter cell line (ChagoK1 18:7:2 s4/GRE) was established by stable transfection of the human bronchogenic carcinoma cell line, ChaGo K1 (ATCC: HTB 168) with a MMTV-GRE-LacZ reporter construct. The generated cell line allows for identification of compounds showing agonist activity at the human glucocorticoid receptor (GR) via induction of LacZ gene expression. Ligand-activated GR binds to the Glucocorticoid Response Element (GRE) in the promoter of the LacZ gene and transcription is initiated. The resulting beta-galactosidase activity is measured through a colour reaction (change in absorbance).Cryo-preserved ChagoK1 18:7:2 s4/GRE cells were suspended in RPMI medium with 10% FBS, 1% NEAA and 1% sodium pyruvate, and seeded as 50000 cells/200 ul/well in 96-well plates and cultured at 37° C. with 5% CO2 and 95% humidity for 24 hours. 1 μl compound was added at different concentrations to the cells and incubated for another 24 hours. Cells were washed once in PBS and lysed with 50 μl of 0.1% Triton-X for 10 min at room temperature. 40 μl of reaction mixture (2.5 mM MgCl2, 0.1 M β-mercapto ethanol, 1.7 mg/ml ONPG and 42.5 mM sodium phosphate, pH 7.5), was added to each well and kept at 37° C. for 60 min. The reaction was then terminated by addition of 100 μl stop solution (300 mM glycine, 15 mM EDTA, pH 11.3, adjusted with NaOH). The plates were measured at 420 nm for absorbance in a SpectraMax reader (Molecular Device).The relative efficacy (% effect) of a compound is calculated based on the full agonist effect of dexamethasone: % Effect=((Sample abs−min abs)/(max abs−min abs))×100To calculate EC50, max, min and slope factor for each compound, a concentration response curve is fitted by plotting % Effect versus compound concentration using the 4 parameter logistic equation: y=A+(B−A)/(1+((10C)/x)D)Where A=min Y, B=max Y, C=log EC50 and D=Slope factor.

Assay: CK2 Kinase Assay: The effectiveness of compounds of the present invention as inhibitors of protein kinases can be readily tested by assays known to those skilled in the art. For example, in vitro protein kinase assays may be conducted with a relevant purified protein kinase and an appropriate synthetic substrate to determine the inhibitory activity of the compounds. Assays for inhibition of CK2 by the instant compounds were performed in 384-well plates with reaction mixtures containing 10 μM of peptide substrate (RRRADDSDDDDD-NH2), [γ-33P]ATP (10 μCi) at 25 μM (CK2A1) or 5 μM (CK2A2), 20 mM Hepes (pH 7.4), 100 mM NaCl, 10 mM MgCl2, 0.25 mM dithiothreitol, Brij-35 at 0.015%, and recombinant CK2A1 (10 nM, Invitrogen) or CK2A2 (5 nM, Upstate Biotechnology). Reaction mixtures were incubated at 30° C. for 1 hour, and reaction products were captured by binding to phosphocellulose (P81) filter plates. Incorporation of radioactive phosphate into the peptide substrate was determined by liquid scintillation counting. The potency of compounds in inhibiting CK2 is expressed as IC50, defined as the concentrations of compounds required to inhibit the enzymatic activity by 50%.The inhibitory activity of the instant compounds may also be measured by recombinant CK2 holoenzyme kinase assays. The assays were performed in U-bottom 384-well plates. The final assay volume was 30 μl prepared from 15 μl additions of enzyme and substrates (fluoresceinated peptide FL-RRRADDSDDDDD-NH2 and ATP) and test compounds in assay buffer (20 mM HEPES pH 7.4, 10 mM MgCl2, 100 mM NaCl, 0.015% Brij35 and 0.25 mM DTT). The reaction was initiated by the combination of bacterially expressed, CK2 α/β or CK2 α′/β holoenzyme with substrates and test compounds. The reaction was incubated at room temperature for 60 minutes and terminated by adding 30 μl of 35 mM EDTA to each sample. The reaction mixture was analyzed on the Caliper LABCHIP® 3000 (Caliper, Hopkinton, Mass.) by electrophoretic separation of the fluorescent substrate and phosphorylated product. Inhibition data were calculated by comparison to no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentration of reagents in the CK2 α/β assay was 25 μM ATP, 1.5 μM FL-RRRADDSDDDDD-NH2, 50 pM CK2 α/β holoenzyme, and 1.6% DMSO. The final concentration of reagents in the CK2 α′/β assay was 10 μM ATP, 1.5 μM FL-RRRADDSDDDDD-NH2, 100 pM CK2 α′/β holoenzyme, and 1.6% DMSO. Dose response curves were generated to determine the concentration required inhibiting 50% of 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.

UniProt: Q08499
Assay: Enzyme Activity Assay: The human PDE4D catalytic domain (UniProt no. Q08499 [5380-L740]) was incubated with a mixture of non-labelled cAMP (cyclic adenosine monophosphate) and fluorescein amidite (FAM) conjugated cAMP and titrated test or reference compound. Following brief incubation the enzymatic reaction was stopped by addition of binding buffer containing nanoparticles with immobilized trivalent metal ions capable of binding 1) AMP phospho groups and 2) terbium (Tb) donor fluorophores. Subsequent excitation of the Tb donor triggers time-resolved FRET to adjacent FAM acceptor molecules resulting in light emission. In the presence of a PDE4 inhibitor, AMP generation was reduced resulting in a lower fluorescence signal. The cAMP phosphodiester is not bound by the detection system.

Assay: FLIPR Ca2+ Flux Assay: In a typical experiment the OX1 and OX2 receptor antagonistic activity of the compounds of the present invention was determined in accordance with the following experimental method. For intracellular calcium measurements, Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 μg/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 μl assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 μl assay buffer containing 1 μM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 μl assay buffer. 30 μl of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 μl, incubated for 5 min and finally 25 μl of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.

Assay: Enzyme Activity Assay: The PHD2181-417 polypeptide (3 μg) was pre-incubated for 30 minutes with test compound prior to assessing the enzymatic activity of the polypeptide. The PHD enzymatic assay was then performed by transferring the purified PHD2181-417 polypeptide (3 μg) mixture with compound to 0.5 ml of reaction mixture containing the following: synthetic HIF-1α peptide comprising residues [KNPFSTGDTDLDLEMLAPYIPMDDDFQLRSFDQLS] (10 μM, California Peptide Research Inc., Napa, Calif.), and [5-14C]-2-oxoglutaric acid (50 mCi/mmol, Moravek Chemicals, Brea, Calif.) in reaction buffer (40 mM Tris-HCl, pH 7.5, 0.4 mg/ml catalase, 0.5 mM DTT, 1 mM ascorbate) for 10 minutes in the presence of compound. The reaction was stopped by addition of 50 μl of 70 mM H3PO4 and 50 μl of 500 mM NaH2PO4, pH 3.2. Detection of [14C]-succinic acid was achieved by separating from [5-14C]-2-oxoglutaric acid by incubating the reaction mixture with 100 μl of 0.16 M DNP prepared in 30% perchloric acid. Next, 50 μl of unlabeled 20 mM 2-oxoglutaric acid/20 mM succinic acid, serving as carrier for the radioactivity, was added to the mixture, and was allowed to proceed for 30 minutes at room temperature. The reaction was then incubated with 50 μl of 1 M 2-oxoglutaric acid for 30 additional minutes at room temperature to precipitate the excess DNP. The reaction was then centrifuged at 2800×g for 10 minutes at room temperature to separate [14C]-succinic acid in the supernatant from the precipitated [14C]-dinitrophenylhydrazone. Fractions of the supernatant (400 μl) were counted using a beta counter (Beckman Coulter, Fullerton, Calif.). Inhibition of PHD2181-417 activity was measured as a decrease in [14C]-succinic acid production. The IC50 values were estimated by fitting the data to a three-parameter logistic function using GraphPad Prism, version 4.02 (Graph Pad Software, San Diego, Calif.). IC50 values up to 10 μM were quantified otherwise were noted as >10 μM. All compounds were diluted at 10 mM in 100% DMSO (w/v) and tested from 10 μM to 3 nM at half-log serial dilutions, with a final concentration of 2% DMSO (w/v) in the assay.
Measurement: IC50 = 100 nM (pChEMBL 7)

UniProt: P21397
Assay: Monoamine Oxidase Assays: Assays were conducted in 96-well black plates with clear bottom (Corning) in a final volume of 100 μL. The assay buffer was 100 mM HEPES, pH 7.5. Each experiment was performed in triplicate within the same experiment. Briefly, a fixed amount of MAO (0.25 μg for MAO-A and 0.5 μg for MA-B) was incubated on ice for 15 minutes in the reaction buffer, in the absence and/or in the presence of various concentrations of inhibitor (e.g., from 0 to 50 μM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition. After leaving the enzyme(s) interacting with the inhibitor, 60 to 90 μM of kynuramine was added to each reaction for MAO-B and MAO-A assay respectively, and the reaction was left for 1 hour at 37° C. in the dark. The oxidative deamination of the substrate was stopped by adding 50 μL (v/v) of NaOH 2N. The conversion of kynuramine to 4-hydroxyquinoline, was monitored by fluorescence (excitation at 320 nm, emission at 360 nm) using a microplate reader (Infinite 200, Tecan).
