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: 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.

Pharmacol. 48(6), 1219-1223 (1994).  (1) The active fraction of PDE 4 (phosphodiesterase IV) was obtained. That is, the livers obtained from three Balb/c mice (male, 12 weeks: obtainable from CLEA Japan, Inc.) were suspended with 30 mL of buffer solution B [20 mM of bis-tris, 5 mM of 2-mercaptoethnol, 2 mM of benzamidine, 2 mM of EDTA, 0.1 mM of 4-(2-aminoethyl)benzensulfonyl hydrochloride, 50 mM of sodium acetate; pH 6.5], then homogenized by Polytron homogenizer. The homogenate were centrifuged under 25,000xG for 10 minutes at 4 C. The supernatant was separated and thus obtained supernatant was further centrifuged under 100,000xG for 60 minutes at 4Â° C., and then filtrated with 0.2 um filter to obtain the soluble fraction.

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.

Target: Delta-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41143
Assay: Radioligand Binding Assay: Radioligand dose-displacement assays used 0.2nM [3H]-Naltrindole (NEN; 33.0 Ci/mmole) with 10-20ug membrane protein (recombinant delta opioid receptor expressend in CHO-K1 cells; Perkin Elmer) in a final volume of 500uL binding buffer (5mM MgCl2, 5% DMSO, 50mM Trizma base, pH 7.4). Non-specific binding was determined in the presence of 25 uM unlabeled naloxone. All reactions were performed in 96-deep well polypropylene plates for 1 h at a temperature of about 25C. Binding reactions were determined 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 five filtration washes with 500uL ice-cold binding buffer. Filter plates were subsequently dried at 50C for 1-2 hours. Fifty uL/well scintillation cocktail (MicroScint20, Packard) was added and plates were counted in a Packard Top-Count for 1 min/well.
