Assay: Human alpha7 nAChR Binding Assay: The ability of compounds to displace binding of radioactive ligands from human α7 nAChR was determined, as a measure of the affinity of the compounds for these ligand-gated ion channels. The [125I]-αBungarotoxin competition binding assay was performed under contract by Cerep Poitiers, France following published the methods (Sharpies et al., J Neurosci. 2000; 20(8):2783-91). SH-SY5Y cells stably expressing human α7 nicotinic acetylcholine receptors, grown to confluency in 175 cm2 flasks, were washed briefly with warm PBS containing (in mm): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.) and scraped into cold phosphate buffer. Cells were washed by centrifugation for 3 min at 500×g and resuspended in 10 mL of ice-cold phosphate buffer. The suspension was homogenized for 10 sec using an Ultraturax and centrifuged for 30 min at 45,000×g. The pellet was resuspended in phosphate buffer (0.5 mL per original flask). SH-SY5Y membranes (30 μg protein) were incubated in a total volume of 2 mL in 50 mM phosphate buffer with 0.05 nM [125I]-αBgt and serial dilutions of test compound. Nonspecific binding was determined in the presence of α-bungarotoxin (1 μM). Samples were incubated for 120 min at 37° C. The reaction was terminated by filtration through Whatman GFA/E filter paper (presoaked overnight in 0.3% polyethyleneimine in PBS), using a Brandel Cell Harvester. Each condition was measured in duplicate. Filters were counted for radioactivity using a scintillation counter. The results were expressed as a percent inhibition of control specific binding obtained in the presence of the test compounds where Inhibition (%)=100−[(measured specific binding/control specific binding)×100].

Target: Melanocyte-stimulating hormone receptor (SINGLE PROTEIN), Homo sapiens
UniProt: Q01726
Assay: Transactivation Assay: In the presence of an activator (agonist), the melanocortin receptor will activate the cAMP pathway which, via the CRE-Luc vector, will result in the synthesis of luciferase. After the addition of a lysis buffer containing a luminescent substrate for luciferase, it will be possible to measure the luminescence proportional to the degree of activation or of inhibition of the receptor. The products are solubilized at 10 mM in DMSO. They are tested in the form of dose-response at a final DMSO concentration of 0.1%. The range comprising 10 points and one zero begins at 10 μM with 4-fold dilutions. For testing agonists, the products are tested alone. For determining the behaviour of antagonists, the products of interest are tested in the presence of 1 nM NDP-MSH (reference agonist). The cells are seeded at a rate of 5000 cells per well (384 well plate) in serum-free DMEM medium, and incubated overnight at 37° C., 5% CO2.The products and the reference ligand (NDP-MSH) are added the following day, and the plates are again incubated for 6 h at 37° C., 5% CO2. After the addition of lysis buffer containing luciferin, the plates are read on a Top-Count instrument. The results are standardized as % activity using the 100% (cells+NDP-MSH at 10 nM) and 0% (cells alone) controls. An EC50 is calculated for each product using the XLFit software. The results are given in nM.

Assay: Binding Assay: Assays were carried out in 16-microL reaction volumes in black 384 Plus F Proxiplates (Perkin-Elmer 6008269). All assay components except test ligand were mixed in coregulator buffer D (Invitrogen PV4420) containing 5 mM DTT and added to the plate at twice their final concentrations in a volume of 8 microL. Test ligands at 2× the final concentration were then added to the wells in 8 □L of coregulator buffer D containing 5 mM DTT and 4% DMSO. Final incubations contained 1× coregulator buffer D, 5 mM DTT, test ligand, 2% DMSO, 50 nM biotinyl-CPSSHSSLTERKHKILHRLLQEGSPS (American Peptide Company; Vista, Calif.), 2 nM Europium anti-GST (Cisbio 61GSTKLB), 12.5 nM streptavidin-D2 (Cisbio 610SADAB), 50 mM KF, and 10 nM of bacterially-expressed human RORc ligand binding domain protein containing an N-terminal 6×His-GST-tag and residues 262-507 of Accession NP_005051. Ten test ligand concentrations were tested in duplicate. After the reaction plates were incubated for 3 h in the dark at room temperature (22-23° C.), the plate was read on an EnVision plate reader (PerkinElmer) following the Europium/D2 HTRF protocol (ex 320, em 615 and 665, 100 Os lag time, 100 flashes, 500 μs window). The time-resolved FRET signal at 665 nm was divided by that at 615 nm to generate the signal ratio of each well.

Assay: BIOLOGICAL ASSAYS: The Class B enzyme activities were measured in the presence of the test inhibitor in a fluorescence assay against a commercially available substrate consisting of a cephalosporin core linking 7-hydroxycoumarin to fluorescein (CCF2-FA). The enzyme (NDM-1, IMP-1 or VIM-1; for a review, see: Meine, M.-R.; Llarrull, L. I.; Vila, A. J. Antibiotics, 2014, 3, 285-316) and the substrate were diluted in 100 mM KH2PO4 buffer (pH 7) containing 0.005% Tween-20 and 10 μM ZnSO4. In the assay, the final concentration of enzyme was 1 pM, 2 pM and 30 pM for NDM-1, IMP-1 and VIM-1, respectively, and the final concentration of CCF2-FA was 1.25 μM. The test inhibitor was dissolved in dimethylsulfoxide and diluted 1:50 in the assay, resulting in a final concentration range of 20 μM to 0.00063 μM. In a 384-well microplate, the test inhibitor was incubated with the metallo-β-lactamase enzyme and the substrate for 2 hours at 25° C. Fluorescence at 460 nm following excitation at 405 nm was measured. The IC50 value was determined from semi-logarithmic plots of enzyme inhibition versus inhibitor concentration, with a curve generated using a 4-parameter fit.

Assay: Inhibition Assay: The kinase activity of purified human MAP4K4 kinase domain was measured by monitoring the phosphorylation of a peptide substrate derived from moesin protein (Leu-Gly-Arg-Asp-Lys-Tyr-Lys-Thr-Leu-Arg-Gln-Ile-Arg-Gln) fluorescently labeled on the N-terminus with 5-carboxyfluorescein using the Caliper LabChip technology (Caliper Life Sciences, Hopkinton, Mass.). To determine inhibition constants (IC50), compounds were serially diluted in DMSO and added to 10 uL kinase reactions containing 1 nM purified MAP4K4 enzyme, 1 uM peptide substrate, 10 uM ATP, 10 mM MgCl2, 1 mM EGTA, 50 mM Hepes pH 7.2, 1 mM DTT, 0.01% Triton X-100, and 2% DMSO. Reactions were incubated at room temperature in Perkin Elmer Proxiplates for 45 minutes and stopped by the addition of 10 uL of an EDTA-containing solution (50 mM Hepes pH 7.2, 40 mM EDTA, 0.02% Triton X-100). The fraction of phosphorylated peptide was determined as a fraction of total peptide substrate using the Caliper Lab Chip 3000 according to the manufacturer's instructions. IC50 values were determined using the four-parameter non-linear fit model.

Assay: Mu-Opioid Receptor Binding Assay: Radioligand dose-displacement binding assays for μ-opioid receptors used 0.3 nM [3H]-diprenorphine (Perkin Elmer, Shelton, Conn.), with 5 mg membrane protein/well in a final volume of 500 μl binding buffer (10 mM MgCl2, 1 mM EDTA, 5% DMSO, 50 mM HEPES, pH 7.4). Reactions were carried out in the absence or presence of increasing concentrations of unlabeled naloxone. All reactions were conducted in 96-deep well polypropylene plates for 2 hours at room temperature. Binding reactions were terminated by rapid filtration onto 96-well Unifilter GF/C filter plates (Perkin Elmer, Shelton, Conn.), presoaked in 0.5% polyethylenimine using a 96-well tissue harvester (Perkin Elmer, Shelton, Conn.) followed by performing three filtration washes with 500 μl of ice-cold binding buffer. Filter plates were subsequently dried at 50° C. for 2-3 hours. BetaScint scintillation cocktail (Perkin Elmer, Shelton, Conn.) was added (50 μl/well), and plates were counted using a Packard Top-Count for 1 min/well. The data were analyzed using the one-site competition curve fitting functions in GraphPad PRISM v. 3.0 or higher (San Diego, Calif.), or an in-house function for one-site competition curve-fitting.

Assay: FlexStation-Ca2+ Influx Assay: On the day of the assay, after removal of the growth media, the cells were washed once with an assay buffer (7 mM Tris-Cl, 20 mM HEPES, 20 mM NaCl, 5 mM KCl, 0.8 mM MgSO4, 4 mM CaCl2, 120 mM NMDG, 5 mM D-glucose, pH 7.4), followed by addition of about 100 ul per well of a Calcium-3 dye diluted with the assay buffer, and storage at room temperature for about 1 hour. A test compound (10 mM stock in 100% dimethyl sulfoxide (DMSO)) was diluted with the assay buffer to various concentrations, from the highest at about 40 μM to be lower by ⅓, and PNU-120596 (available from Sigma) for amplifying Ca2+ permeability signaling was diluted to about 30 μM with the assay buffer. Epibatidine (available from Sigma) in a final concentration of about 1 μM was used as a positive control group.
