Assay: Radioligand Binding Assay: Radioligand binding assays (screening and dose-displacement) used 0.1nM [3H]-nociceptin (NEN; 87.7 Cl/nimole) with 10-20 ug membrane protein in a final volume of 500uL binding buffer (10mM MgCl2, 1mM EDTA, 5% DMSO, 50mM HEPES, pH 7.4). Non-specific binding was determined in the presence of 10nM unlabeled nociceptin (American Peptide Company). All reactions were performed in 96-deep well polypropylene plates for 1 h at about 25C. Binding reactions were terminated by rapid filtration onto 96-well Unifilter GF/C filter plates (Packard) presoaked in 0.5% polyethylenimine (Sigma). Harvesting was performed using a 96-well tissue harvester (Packard) followed by three filtration washes with 500uL ice-cold binding buffer. Filter plates were subsequently dried at 50C for 2-3 hours. Fifty uL/well scintillation cocktail (BetaScint; Wallac) was added and plates were counted in a Packard Top-Count for 1 min/well.

UniProt: Q00987
Assay: FRET Assay: Methods: An HDM2 FRET assay was developed to assess the compounds' inhibitory activity towards binding of p53 protein. A truncated version of HDM2 with residues 17 to 125 (containing p53 binding surface, Science (1994) 265, 346-355), with N-terminal His and Thioredoxin tag was generated in pET32a expression vector and expressed in E. coli strain BL21(DE3)Rosetta. Protein was purified using Ni-affinity chromatography, followed by size exclusion chromatography using Superdex 75 26/60 column. To assess inhibition of p53 binding to HDM2, a FITC labeled 8-mer peptide (SEQ ID NO:1: Ac-Phe-Arg-Dpr-Ac6c-(6-Br)Trp-Glu-Glu-Leu-NH2; Anal Biochem. 2004 Aug. 1; 331(1):138-46) with strong affinity towards the p53 binding pocket of HDM2 was used. The HDM2 assay buffer contained 1x Phosphate Buffered Saline (Invitrogen, Cat#14190), 0.01% BSA (Jackson ImmunoResearch, Cat#001-000-162), 0.01% Tween-20. In the 1x assay buffer recombinant HDM2 protein, peptide and Lumi-4-Tb Cryptate-conjugate mouse.

Assay: Radioligand Binding Assay: The affinity of a test compound for the human dopamine receptor subtype hDRD2 was determined by radioligand binding assays in CHO-K1 cells stably transfected with hDRD2 receptor, as follows. The cDNA coding sequence of hDRD2 (GenBank accession No. X51362) was subcloned into the mammalian expression vector pcDNA3.1/GS (Life Technologies). Clonal cell lines stably expressing hDRD2 were obtained by transfection into CHO-K1 cells and subsequently selected with culture medium containing 0.3 mg/mL of zeocin (Life Technologies).Membranes for in vitro receptor binding assays were obtained by the following procedures. CHO-K1 cells expressing hDRD2 were homogenized in ice-cold buffer with 10 mM Tris-HCl, 5 mM EDTA, 3 mM EGTA, 1 mM phenylmethylsuphonyl fluoride, pH 7.6 using Polytron PT10-35GT (Kinematica) at 18,000 rpm for 30 seconds and centrifuged at 500xg for 10 minutes.

Assay: Mu-Opioid GTPgammaS Binding Assay: [35S]GTP gamma S functional assays were conducted using freshly thawed mu-receptor membranes. Assay reactions were prepared by sequentially adding the following reagents to binding buffer (100 mM NaCl, 10 mM MgCl2, 20 mM HEPES, pH 7.4) on ice (final concentrations indicated): membrane protein (0.026 mg/mL), saponin (10 mg/mL), GDP (3 mM) and [35S]GTP gamma S (0.20 nM; NEN). The prepared membrane solution (1904/well) was transferred to 96-shallow well polypropylene plates containing 10 uL of 20x concentrated stock solutions of the agonist DAMGO ([D-Ala2, N-methyl-Phe4 Gly-ol5]-enkephalin) prepared in DMSO. Plates were incubated for 30 min at about 25 C. with shaking. Reactions were terminated by rapid filtration onto 96-well Unifilter GF/B filter plates (Packard, Meriden, Conn.) using a 96-well tissue harvester (Brandel, Gaithersburg, Md.) followed by three filtration washes with 200 mL of ice-cold wash buffer.

Target: Receptor tyrosine-protein kinase erbB-4 (SINGLE PROTEIN), Homo sapiens
UniProt: Q15303
Assay: HotSpot kinase assay: IC50s were determined using the in vitro HotSpot kinase assay (purified enzymes, 33P-ATP, an appropriate substrate and 1 μM ATP.). For enzyme inhibition assays, compounds were tested in range of ten concentrations from 10 uM to 0.0005 uM using purified enzymes and the Hotspot kinase assay. Reaction conditions were 1 uM ATP, one hour incubation with inhibitor, and kinase activity detected using 33-ATP phosphorylation of an appropriately selected peptide substrate.

Target: Prolyl hydroxylase EGLN2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q96KS0
Assay: Inhibition Assay: Hydroxylated HIF bonds specifically to the von Hippel-Lindau protein-elongin B-elongin C complex (VBC complex). This interaction occurs only if HIF is hydroxylated on a conserved prolyl radical. It is the basis for the biochemical determination of HIF prolyl hydroxylase activity. The test is carried out as described [Oehme F., Jonghaus W., Narouz-Ott L., Huetter J., Flamme I., Anal. Biochem. 330 (1), 74-80 (2004)].

Target: Aurora kinase A (SINGLE PROTEIN), Homo sapiens
UniProt: O14965
Assay: Enzyme Inhibtion Assay: To determine Aurora A and C activity of representative compounds of the invention, Active Aurora A or C enzyme was incubated in wells of a 384 well plate with biotinylated STK substrate-2 (Upstate), 1 mM ATP, and various concentrations of inhibitors in a Hepes buffer, pH 7.4 containing MgCl2, sodium othrovanadate, and Triton X-100. After 1 hour, the reaction was stopped with EDTA and anti-phospho-STK antibody Europium Cryptate (Upstate) and SA-XL665 (Upstate) were added to detect the phosphopeptide. The amount of phosphorylation was determined by the time-resolved fluorescence ratio of signals at 665 nm and 615 nm.
