Target: Mu-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35372
Assay: Receptor Binding Assay: The hMOP receptor binding assay was performed as homogeneous SPA-assay (scintillation proximity assay) using the assay buffer 50 mM TRIS-HCl (pH 7.4) supplemented with 0.052 mg/ml bovine serum albumin (Sigma-Aldrich Co. St. Louis. Mo.). The final assay volume (250 ul/well) included 1 nM of [N-allyl-2.3-3H]naloxone as ligand (PerkinElmer Life Sciences. Inc. Boston. Mass. USA). and either test compound in dilution series or 25 uM unlabelled naloxone for determination of unspecific binding. The test compound was diluted with 25% DMSO in H2O to yield a final 0.5% DMSO concentration. which also served as a respective vehicle control. The assay was started by adding wheat germ agglutinin coated SPA beads (GE Healthcare UK Ltd. Buckinghamshire. UK) which had been preloaded with hMOP receptor membranes (PerkinElmer Life Sciences. Inc. Boston. Mass. USA). After incubation for 90 minutes at RT and centrifugation for 20 minutes at 500 rpm the signal rate was measured by means of a 1450 Microbeta Trilux ??-counter (PerkinElmer Life Sciences/Wallac. Turku. Finland). Half-maximal inhibitory concentration (IC50) values reflecting 50% displacement of [3H]naloxone-specific receptor binding were calculated by nonlinear regression analysis and Ki values were calculated by using the Cheng-Prusoff equation. (Cheng and Prusoff. 1973).

Assay: Aurora-A, Aurora-B, JAK1, JAK2, JAK3 Enzyme Assays: The inhibitory activity of compounds against AURKA, AURKB, JAK1, JAK2 and JAK3 was determined in Z'-LYTE® assays run by ThermoFisher Scientific as part of their SelectScreen® Biochemical Kinase Profiling Service. The Z'-LYTE® biochemical assay format employs a fluorescence-based, coupled-enzyme format and is based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to proteolytic cleavage. The peptide substrate is labeled with two fluorophoresone at each endthat make up a FRET pair. In the primary reaction, the kinase transfers the gamma-phosphate of ATP to a single tyrosine, serine or threonine residue in a synthetic FRET-peptide. In the secondary reaction, a site-specific protease recognises and cleaves non-phosphorylated FRET-peptides. Phosphorylation of FRET-peptides suppresses cleavage by the Development Reagent. Cleavage disrupts FRET between the donor (i.e., coumarin) and acceptor (i.e., fluorescein) fluorophores on the FRET-peptide, whereas uncleaved, phosphorylated FRET-peptides maintain FRET. A ratiometric method, which calculates the ratio (the Emission Ratio) of donor emission to acceptor emission after excitation of the donor fluorophore at 400 nm, is used to quantitate reaction progress. Both cleaved and uncleaved FRET-peptides contribute to the fluorescence signals and therefore to the Emission Ratio. The extent of phosphorylation of the FRET-peptide can be calculated from the Emission Ratio. The Emission Ratio will remain low if the FRET-peptide is phosphorylated (i.e., no kinase inhibition) and will be high if the FRET-peptide is non-phosphorylated (i.e., kinase inhibition).10 point three-fold dilution compound concentration-response curves, with a top concentration of 10 μM were generated from 10 mM stocks of compound solubilised in DMSO. All assays were performed in black, non-binding, low volume Corning 384-well plates (cat. #4514, Corning), in a total reaction volume of 10 μL and 1% (v/v) final DMSO concentration. 2.4 μL Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA), 5 μL 2× Peptide/Kinase mixture (detailed below for each kinase) and 2.5 μL 4×ATP Solution (prepared in Kinase Buffer) were added separately to the compound plates, placed on a plate shaker for 30 sec, and then incubated for 60 mins at room temperature. The kinase reaction was then quenched by the addition of 5 μL of Development Reagent (ThermoFisher Scientific proprietary). Assay plates were placed on a plate shaker for 30 sec, incubated for 60 mins at room temperature, and then read using a fluorescence plate reader. IC50 values were calculated using XLfit software (IDBS Ltd, Surrey, UK), with the curve fit to model number 205 (sigmoidal dose-response model).

Assay: ROCK Kinase Inhibition Assays: All compounds were initially prepared as 10 mM stocks in anhydrous dimethylsulfoxide (DMSO). A 20 μl aliquot of the 10 mM solutions was transferred to individual wells in column 1 of a 96-well polypropylene microtiter plate (Corning #3363) and diluted with DMSO to give a final compound concentration of 4 mM. Test compounds were then serially diluted 1:5 in DMSO for an 11-point concentration response and further diluted in the assay buffer bringing all compound concentrations to a final range of 100 μM to 10 pM in 2.5% DMSO. The assay was performed in white 96-well, flat-bottom, half-area, non-binding assay plate (Corning #3642) in assay buffer consisting of 20 mM HEPES (pH 7.5), 10 mM MgCl2*6H2O, 100 μM sodium orthovanadate, 0.05% CHAPS and 0.1% bovine serum albumin. A 10 μL aliquot of compound from each well of the intermediate dilution plate and 20 μL of a 2× substrate/enzyme solution containing acceptor substrate (800 nM RSK2 peptide KRRRLSSLRA (SEQ ID NO: 1)), ROCK2 enzyme (10 nM), or ROCK1 enzyme, and 1,4-Dithiothreitol (DTT, 2 μM) were added to all wells. The reaction was initiated by the addition of 10 μL of 4× stock solution ATP (2 ∥M). Reactions were thoroughly mixed manually, covered and allowed to incubate at room temperature for 75 min. Protein kinase activity was quantitated using Promega's KINASE-GLO luminescent Kinase Assay Kit according to the manufacturer's directions. ATP concentrations remaining in Test wells following the termination of the enzymatic reaction were compared against control wells containing equivalent amounts of DMSO containing no inhibitor (CTRL). ATP concentrations in both Test wells and CTRL wells were normalized against background (BKG) ATP concentrations in wells containing concentrations of inhibitor that completely inhibited the protein kinase under investigation (i.e. a concentration that prevented any consumption of ATP over the course of the incubation). Percent of Control (POC) values were determined for each concentration of compound tested according to the equation: POC=((Test well value−BKG)/(CTRL−BKG))*100IC50 values were calculated using the following 4-parameter logistic curve-fitting algorithm: f(x)=(A+((B−A)/(1+((x/C){circumflex over ( )}D))))IC50 values were converted to Ki values using the Cheng-Prusoff Equation: Ki=IC50/(1+([ATP]/Km ATP])).

UniProt: Q96GD4
Assay: Aurora-A, Aurora-B, JAK1, JAK2, JAK3 Enzyme Assays: The inhibitory activity of compounds against AURKA, AURKB, JAK1, JAK2 and JAK3 was determined in Z'-LYTE® assays run by ThermoFisher Scientific as part of their SelectScreen® Biochemical Kinase Profiling Service. The Z'-LYTE® biochemical assay format employs a fluorescence-based, coupled-enzyme format and is based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to proteolytic cleavage. The peptide substrate is labeled with two fluorophoresone at each endthat make up a FRET pair. In the primary reaction, the kinase transfers the gamma-phosphate of ATP to a single tyrosine, serine or threonine residue in a synthetic FRET-peptide. In the secondary reaction, a site-specific protease recognises and cleaves non-phosphorylated FRET-peptides. Phosphorylation of FRET-peptides suppresses cleavage by the Development Reagent. Cleavage disrupts FRET between the donor (i.e., coumarin) and acceptor (i.e., fluorescein) fluorophores on the FRET-peptide, whereas uncleaved, phosphorylated FRET-peptides maintain FRET. A ratiometric method, which calculates the ratio (the Emission Ratio) of donor emission to acceptor emission after excitation of the donor fluorophore at 400 nm, is used to quantitate reaction progress. Both cleaved and uncleaved FRET-peptides contribute to the fluorescence signals and therefore to the Emission Ratio. The extent of phosphorylation of the FRET-peptide can be calculated from the Emission Ratio. The Emission Ratio will remain low if the FRET-peptide is phosphorylated (i.e., no kinase inhibition) and will be high if the FRET-peptide is non-phosphorylated (i.e., kinase inhibition).10 point three-fold dilution compound concentration-response curves, with a top concentration of 10 μM were generated from 10 mM stocks of compound solubilised in DMSO. All assays were performed in black, non-binding, low volume Corning 384-well plates (cat. #4514, Corning), in a total reaction volume of 10 μL and 1% (v/v) final DMSO concentration. 2.4 μL Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA), 5 μL 2× Peptide/Kinase mixture (detailed below for each kinase) and 2.5 μL 4×ATP Solution (prepared in Kinase Buffer) were added separately to the compound plates, placed on a plate shaker for 30 sec, and then incubated for 60 mins at room temperature. The kinase reaction was then quenched by the addition of 5 μL of Development Reagent (ThermoFisher Scientific proprietary). Assay plates were placed on a plate shaker for 30 sec, incubated for 60 mins at room temperature, and then read using a fluorescence plate reader. IC50 values were calculated using XLfit software (IDBS Ltd, Surrey, UK), with the curve fit to model number 205 (sigmoidal dose-response model).
