Assay: Mobility Shift Assay: Agents: 1-fold kinase buffer without MnCl2: 50 mM HEPES, pH 7.5, 0.0015% Brij-35, 10 mM MgCl2, 2 mM DTT. 1-fold kinase buffer with MnCl2: 50 mM HEPES, pH 7.5, 0.0015% Brij-35, 10 mM MgCl2, 10 mM MnCl2, 2 mM DTT. Termination solution: 100 mM HEPES, pH 7.5, 0.0015% Brij-35, 0.2% Coating Reagent#3, 50 mM EDTA. 2.5-fold kinase solution: The kinase was added to the 1-fold kinase buffer to form a 2.5-fold kinase solution. 2.5-fold substrate solution: FAM fluorescence-labelled polypeptide and ATP were added to the 1-fold kinase buffer to form a 2.5-fold substrate solution. Compounds: The final test concentration of the compound was 10 μM at maximum. Firstly, a 50-fold concentration (i.e. 500 μM) was prepared with 100% DMSO. The compound was diluted with 100% DMSO by 5 folds at 5 concentrations (successively 500 μM, 100 μM, 20 μM, 4 μM, and 0.8 μM). After diluting with 1-fold kinase buffer by 10 folds, 5 μl of the samples were transferred to a 384-well reaction plate. Two negative control wells and two positive control wells were set at each line respectively. Replication was made in a 96-well plate in five concentrations of 5-fold compound. 10% DMSO was added to the positive control well, and 5 μl of EDTA (250 mM) was added to the negative control well. Procedure: To the 384-well reaction plate was added 5-fold compound dissolved in 10% DMSO at 5 μl/well. To the 384-well reaction plate was added 2.5-fold kinase solution at 10 Î¼l/well. The plate was incubated at room temperature for 10 mins. To the 384-well reaction plate was added 2.5-fold substrate solution at 10 μl/well. The plate was incubated at 28° C. for a certain period. 25 μl termination solution was added to terminate the reaction.

Assay: cAMP Assay: CHO cells expressing human CB1 or CB2 receptors are seeded 17-24 hours prior to the experiment 50.000 cells per well in a black 96 well plate with flat clear bottom (Corning Costar #3904) in DMEM (Invitrogen No. 31331), 1×HT supplement, with 10% fetal calf serum and incubated at 5% CO2 and 37° C. in a humidified incubator. The growth medium was exchanged with Krebs Ringer Bicarbonate buffer with 1 mM IBMX and incubated at 30° C. for 30 min. Compounds were added to a final assay volume of 100 μl and incubated for 30 min at 30° C. Using the cAMP-Nano-TRF detection kit the assay (Roche Diagnostics) was stopped by the addition of 50 μl lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN3) and 50 μl detection solutions (20 μM mAb Alexa700-cAMP 1:1, and 48 μM Ruthenium-2-AHA-cAMP) and shaken for 2 h at room temperature. The time-resolved energy transfer is measured by a TRF reader (Evotec Technologies GmbH), equipped with a ND:YAG laser as excitation source. The plate is measured twice with the excitation at 355 nm and at the emission with a delay of 100 ns and a gate of 100 ns, total exposure time 10 s at 730 (bandwidth 30 nm) or 645 nm (bandwidth 75 nm), respectively. The FRET signal is calculated as follows: FRET=T730-Alexa730-P(T645-B645) with P=Ru730-B730/Ru645-B645, where T730 is the test well measured at 730 nM, T645 is the test well measured at 645 nm, B730 and B645 are the buffer controls at 730 nm and 645 nm, respectively. cAMP content is determined from the function of a standard curve spanning from 10 μM to 0.13 nM cAMP.

Target: Mu-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35372
Assay: Functional Assay (GTPgammaS Binding): The EC50 and Imax for mu opioid receptors was determined using a [I35S]GTPgammaS binding assay. This assay measures the functional properties of a compound by quantifying the level of G-protein activation following agonist binding in studies using stably transfected cells, and is considered to be a measure of the efficacy of a compound. Membranes from CHO (Chinese Hamster Ovary) cells that stably expressed the cloned human Mu opioid receptor were used in the experiments. Specifically, in a final volume of 0.5 mL, 12 different concentrations of each test compound were incubated with 7.5 ug of CHO cell membranes that stably expressed the human mu opioid receptor. The assay buffer consisted of 50 mM Tris-HCl, pH 7.4, 3 mM MgCl2, 0.2 mM EGTA, 3 uM GDP, and 100 mM NaCl. The final concentration of [35S]GTPgammaS was 0.080 nM. Nonspecific binding was measured by inclusion of 10 uM GTPgammaS. Binding was initiated by the addition of the membranes.

Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation. Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nav 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz. Cells were then left unclamped for a period of 3 to 8 minutes while a single concentration of test compound was added. Cells were then reclamped and put through the same voltage protocol.

Assay: Kinase Assay: Biochemical PDGFRβ kinase assays were performed in 96 well microtiter plates that were coated overnight with 75 μg of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.4. The coated plates were washed with 2 mls per well PBS+0.05% Tween-20 (PBS-T), blocked by incubation with PBS containing 1% BSA, then washed with 2 mls per well PBS-T prior to starting the reaction. Reactions were carried out in 100 μL reaction volumes containing 36 μM ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl2, 0.1 mM MnCl2 and 0.2 mM Na3VO4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 20 ul per well of kinase buffer containing 200-300 ng purified cytoplasmic domain PDGFR-b protein (Millipore). Following a 60 minute incubation at 30° C., the reactions were washed 2 mls per well PBS-T.

UniProt: Q64663
Assay: FLIPR Assay: 1321 N1 cells expressing the recombinant human, rat or mouse P2X7 channel was cultured in HyQ DME/(HyClone/Dulbecco's Modified Eagle Medium) high glucose supplemented with 10% Fetal Bovine Serum (FBS) and appropriate selection marker. Cells were seeded at a density of 25000 cells/well (96-well clear bottom black walled plates) in 100 ul volume/well. On the day of the experiment, cell plates were washed with assay buffer, containing (in mM): 130 NaCl, 2 KCl, 1 CaCl2, 1 MgCl2, 10 HEPES, 5 glucose; pH 7.40 and 300 mOs. After the wash, cells were loaded with the Calcium-4 dye (Molecular Device) and incubated in the dark for 60 minutes. Test compounds were prepared at 250Ã¿ the test concentration in neat DMSO. Intermediate 96-well compound plates were prepared by transferring 1.2 uL of the compound into 300 uL of assay buffer. A further 3x dilution occurred when transferring 50 uL/well of the compound plate to 100 uL/well in the cell plate. Cells were incubateÂ  with test compounds and dye for 30 minutes. Calcium dye fluorescence was monitored in FLIPR as the cells were challenged by adding 50 uL/well of BzATP (final concentration is 250 uM BzATP (human and rat) or 600 (mouse)). The fluorescence change was measured 180 seconds after adding the agonist.

UniProt: O14744
Assay: Biochemical Assay: Molecular Biology: Full-length human PRMT5 (NM_006109.3) transcript variant 1 clone was amplified from a fetal brain cDNA library, incorporating flanking 5′ sequence encoding a FLAG tag (MDYKDDDDK) (SEQ ID NO.:4) fused directly to Ala 2 of PRMT5. Full-length human MEP50 (NM_024102) clone was amplified from a human testis cDNA library incorporating a 5′ sequence encoding a 6-histidine tag (MHHHHHH) (SEQ ID NO.:5) fused directly to Arg 2 of MEP50. The amplified genes were sublconed into pENTR/D/TEV (Life Technologies) and subsequently transferred by Gateway attL×attR recombination to pDEST8 baculvirus expression vector (Life Technologies).Protein Expression. Recombinant baculovirus and Baculovirus-Infected Insect Cells (BIIC) were generated according to Bac-to-Bac kit instructions (Life Technologies) and Wasilko, 2006, respectively. Protein over-expression was accomplished by infecting exponentially growing Spodoptera frugiperda (SF9) cell culture at 1.2×106 cell/ml with a 5000 fold dilution of BIIC stock. Infections were carried out at 27° C. for 72 hours, harvested by centrifugation, and stored at −80° C. for purification.
