Target: Mu-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35372
Assay: Opioid Receptor Binding Assay: The Ki (binding affinity) for opioid receptors was determined using a competitive displacement assay as previously described in Neumeyer (Journal of Med. Chem. 2012, p 3878), which is incorporated herein in its entirety. Briefly, membrane protein from CHO (Chinese Hamster Ovarian) cells that stably expressed the cloned human μ opioid receptor were incubated with 12 different concentrations of the compound set forth herein in the presence of 0.25 nM [3H]DAMGO (see Tiberi et al., Can. J. Physiol. Pharmacol. 1988, Vol. 66, p 1368, which is incorporated by reference herein in its entirety) in a final volume of 1 mL of 50 mM Tris-HCl, pH 7.5 at 25° C. Incubation times of 60 min were used for [3H]DAMGO (see Gulati et al., Life Sci. 1990, Vol. 47, p 159, which is incorporated by reference herein in its entirety). Nonspecific binding was measured by inclusion of 10 μM naloxone. The binding was terminated by filtering the samples through Schleicher & Schuell No. 32 glass fiber filters using a Brandel 48-well cell harvester. The filters were subsequently washed three times with 3 mL of cold 50 mM Tris-HCl, pH 7.5, and were counted in 2 mL Ecoscint A scintillation fluid. IC50 values were calculated by least squares fit to a logarithm-probit analysis. Ki values of unlabelled compounds were calculated from the equation Ki=(IC50)/1+S where S=(concentration of radioligand)/(Kd of radioligand) (Cheng and Prusoff, 1973).

Assay: Human Factor D Assay: Human Factor D (purified from human serum, Complement Technology, Inc.) at 80 nM final concentration was incubated with test compound at various concentrations for 5 minutes at room temperature in 50 mM Tris, 1M NaCl, pH 7.5. A synthetic substrate Z-L-Lys-SBzl and DTNB (Ellman's reagent) are added to final concentrations of 100 μM each. Absorbance at 405 nm (A405) was recorded at 30 second intervals for 30 minutes using a microplate spectrophotometer.

UniProt: P41145
Assay: Receptor Binding Assay : μ-Opioid: 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 hr 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.

A HEK293 cell over expressing human P2X7 was harvested using HQTase reagent to detach the cells from T75 cm flask. The harvested cells are centrifuged @1200 rpm for 5 min at room temperature. The viability of cells was determined by Trypan blue dye and the cells are plated @10,000 cell/well in 50 ul volume in a 384W BD Poly lysine coated plate and incubated overnight at 37 C. After overnight incubation, the culture medium was replaced with 35 ul/well assay buffer (5 mM KCl, 0.1 mM CaCl2, 5 mM Glucose, 10 mM HEPES buffer pH7.4 containing 125 mM NaCl. The serial dilution of compounds was performed using Bravo liquid handling instrument and the compounds were added using Bravo to the cell assay plate starting at 2.5 uM with three dilutions for 10 points. The positive control inhibitor compound was added to column 23. The plate was shaken slowly on a plate shaker for 10 seconds. The cells were incubated with the compound for 20 minutes at room temperature. After the incubation period, YO PRO dye (1 uM) along with BzATP (10 uM) were added to cells at 10 ul/well.

Assay: Competition Binding Assay: h-5HT3: In brief, Chinese Hamster Ovary (CHO) cells stably expressing human 5-HT3 serotonin receptors, grown to confluence in 175 cm2 flasks. Following aspiration of the culture medium, cells were harvested by mechanical agitation in ice cold PBS containing (in mM): (150 NaCl, 8 K2HPO4, 2 KH2PO4, pH 7.4, 37° C.), centrifuged at 4,000 g for 10 min and subsequently stored as a cell pellet at −80 C. When required, the pellet was thawed and resuspended in ice cold homogenization buffer (Tris 50 mM, EGTA 5.0 mM, phenylmethylsulphonylfluoride 0.1 mM, pH 7.6) and homogenized.

Compounds in 100% DMSO (1 ul) were spotted into a 384-well white opaque OptiPlate using a Bravo automated liquid handling platform outfitted with a 384-channel head (Agilent Technologies). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMYD3, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the SMYD3 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD3 for 30 min at room temperature, then a cocktail (10 ul) containing SAM and MEKK2 was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: SMYD3 was 0.4 nM, 3H-SAM was 8 nM, MEKK2 was 12 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (10 ul) to a final concentration of 100 uM, which dilutes the 3H-SAM to a level where its incorporation into MEKK2 is no longer detectable. Radiolabeled MEKK2 was detected using a scintillation proximity assay (SPA). 10 uL of a 10 mg/mL solution of SPA beads in 0.5 M citric acid was added and the plates centrifuged at 600 rpm for 1 min to precipitate the radiolabeled MEKK2 onto the SPA beads.

InChIKey: RZQVTEVLURSKIN-JOCHJYFZSA-N
Target: Toll-like receptor 7 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NYK1
Assay: Inhibition of the Activation Assay: As human TLR7 expressing cell line, HEK293 cell line was bought from IMGENEX Corporation (TLR7/NF-ηB/SEAPorter HEK293 cell), which is human embryonic kidney cell line and stably expresses full-length human TLR7 gene and secreted alkaline phosphatase (SEAP) reporter gene under the transcriptional control of an NE-ηB response element. The TLR7/NF-ηB/SEAPorter HEK293 cell was cultivated with DMEM containing 10% fetal bovine serum (FBS) and 10 μg/mL blasticidin S at 37° C. in the presence of 5% CO2. The TLR7/NF-ηB/SEAPorter HEK293 cell was seeded into 96-well microtiter plate at 5×104 cell/90 μL/well, and the place was cultivated at 37° C. in a CO2 incubator overnight. Each test compound that was diluted with the medium was added to the wells (10 μL/well), wherein each final concentration was adjusted to 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, and 10 μmol/L, or 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, and 100 μmol/L. After 0.5 hour, R-848 that is TLR7/8 ligand was added to each well (10 μL/well), wherein each final concentration was adjusted to 200 nmol/L. The total volume was adjusted to 110 μL/well, the test samples were incubated in CO2 incubator for 20±1 hours, and then the SEAP activity was measured as activation of TLR7. The SEAP activity was evaluated as follows: p-nitro-phenyl phosphate (pNPP) (Invitrogen) was added to the incubated sample (50 μL/well); after 15 minutes, 4 mol/L sodium hydroxide solution (nacalai tesque) was added thereto (50 μL/well) to quench the reaction; and the absorbance of each sample was measured at 405 nm with microplate reader Elx808 (BioTek). The 50% inhibitory concentration (IC50 value) of each sample compound was calculated based on 100% of the SEAP activity wherein the test sample comprises no sample compound.
