Assay: Activity Assay: A human acute lymphoblastic lymphoma T cell line MOLT-4 (which can be purchased under ATCC No. CRL-1582 from ATCC) was cultured in an RPMI1640 medium containing 10% fetal bovine serum to obtain 5108 MOLT-4 cells. The cells were recovered by centrifugation and suspended in 10 ml of buffer solution A (25 mM Tris-HCl, 5 mM 2-mercaptoethanol, 2 mM benzamidine, 2 mM EDTA, and 0.1 mM 4-(2-aminoethyl)benzenesulfonyl hydrochloride, pH 7.5). The cells were homogenized using a Polytron homogenizer and centrifuged (4° C., 25,000 g, 10 minutes). Then, the supernatant was further ultracentrifuged (4° C., 100,000 g, 60 minutes). The obtained supernatant was filtered through a 0.2um filter to obtain a soluble fraction.HiTrap Q HP column (5 ml2, GE Healthcare Japan Corp.) equilibrated with buffer solution A was charged with the obtained soluble fraction. Phosphodiesterase was eluted with 300 ml of buffer solution A containing a linear gradient solution of 0 to 0.8 M NaCl to recover sixty 5-ml fractions. Each fraction was tested for cAMP-metabolizing phosphodiesterase activity. In each fraction, a fraction eluted as an active peak centered around 250 mM NaCl was collected from fractions that had cAMP metabolic activity and did not lose the metabolic activity by 10uM rolipram (PDE4 selective inhibitor) and 10uM milrinone (PDE3 selective inhibitor). In order to confirm whether or not PDE10A mRNA was expressed in the MOLT-4 cells, total RNA was prepared from the MOLT-4 cells according to a standard method and analyzed by RT-PCR using PDE10A gene-specific primers (PDE10A sense primer: 5'-TGCTCCATGGTGGAAGTGGA-3' (SEQ ID NO: 1) and PDE10A antisense primer: 5'-CAACTGGAAGCATGCGGTCA-3' (SEQ ID NO: 2)). As a result, PDE10A mRNA was detected from the total RNA of the MOLT-4 cells. On the other hand, total RNA was prepared from Jurkat cells, one type of human T cell, and similarly subjected to RT-PCR. As a result, PDE10A mRNA was rarely detected. An active peak centered around 250 mM NaCl was not observed in fractions obtained by the treatment of Jurkat cells in the same way as above. Eur J Biochem. 1999, 266 (3), 1118-2 has reported that PDE10A from the rat striatum and testis is eluted as an active peak centered around 250 mM NaCl.

Assay: TR-FRET Assay: The β-secretase enzyme used in the TR-FRET is prepared as follows: The cDNA for the soluble part of the human β-Secretase (AA 1-AA 460) was cloned using the ASP2-Fc 10-1-IRES-GFP-neoK mammalian expression vector. The gene was fused to the Fc domain of IgG1 (affinity tag) and stably cloned into HEK 293 cells. Purified sBACE-Fc was stored in −80° C. in Tris buffer, pH 9.2 and had a purity of 40%.The enzyme (truncated form) was diluted to 6 μg/mL (stock 1.3 mg/mL) and the substrate (Europium)CEVNLDAEFK(Qsy7) to 200 nM (stock 120 μM) in reaction buffer (NaAcetate, chaps, triton x-100, EDTA pH4.5). The robotic systems Biomek FX and Velocity 11 were used for all liquid handling and the enzyme and substrate solutions were kept on ice until they were placed in the robotic system. Enzyme (9 μl) was added to the plate then 1 μl of compound in dimethylsulphoxide was added, mixed and pre-incubated for 10 minutes. Substrate (10 μl) was then added, mixed and the reaction proceeded for 15 minutes at r.t. The reaction was stopped with the addition of Stop solution (7 μl, NaAcetate, pH 9). The fluorescence of the product was measured on a Victor II plate reader with an excitation wavelength of 340 nm and an emission wavelength of 615 nm. The assay was performed in a Costar 384 well round bottom, low volume, non-binding surface plate (Corning #3676). The final concentration of the enzyme was 2.7 g/ml; the final concentration of substrate was 100 nM (Km of 250 nM). The dimethylsulphoxide control, instead of test compound, defined the 100% activity level and 0% activity was defined by wells lacking enzyme (replaced with reaction buffer). A control inhibitor was also used in dose response assays and had an IC50 of 150 nM.

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.

Assay: Fluorescence Polarization Assays: In another embodiment, Fluorescence Polarization ("FP") based assays may be used to detect and monitor ligand binding. Fluorescence polarization is a versatile laboratory technique for measuring equilibrium binding, nucleic acid hybridization, and enzymatic activity. Fluorescence polarization assays are homogeneous in that they do not require a separation step such as centrifugation, filtration, chromatography, precipitation, or electrophoresis. These assays are done in real time, directly in solution and do not require an immobilized phase. Polarization values can be measured repeatedly and after the addition of reagents since measuring the polarization is rapid and does not destroy the sample. Generally, this technique can be used to measure polarization values of fluorophores from low picomolar to micromolar levels.

UniProt: P56817
Assay: BACE1 Cell-Free Assay: A synthetic APP substrate that can be cleaved by beta-secretase having N-terminal biotin and made fluorescent by the covalent attachment of Oregon Green at the Cys residue is used to assay beta-secretase activity in the presence or absence of the inhibitory compounds. The substrate is Biotin-GLTNIKTEEISEISY^EVEFR-C[Oregon Green]KK-OH. The BACE1 enzyme is affinity purified material from conditioned media of CHO-K1 cells that have been transfected with a soluble BACE construct (BACE1deltaTM96His). Compounds are incubated in a log dose response curve from a top concentration of 100 uM with BACE1 enzyme and the biotinylated fluorescent peptide in 384-well black plates (Thermo Scientific #4318). BACE1 is at a final concentration of 0.1 nM with a final concentration of peptide substrate of 150 nM in a reaction volume of 30 uL assay buffer [100 mM sodium acetate, pH 4.5 (brought to pH with acetic acid), and 0.001% Tween-20]. Plates are covered and incubated for 3 hours at 37° C. The reaction is stopped with the addition of 30 uL of 1.5 uM Streptavidin (Pierce, #21125). After a 10 minute incubation at room temperature, plates are read on a PerkinElmer EnVision for fluorescence polarization (Ex485 nm/Em530 nm). The activity of the beta-secretase enzyme is detected by changes in the fluorescence polarization that occur when the substrate is cleaved by the enzyme. Incubation in the presence of compound inhibitor demonstrates specific inhibition of beta-secretase enzymatic cleavage of the synthetic APP substrate.

UniProt: P41594
Assay: Intracellular Ca2+ Mobilization Assay: A monoclonal HEK-293 cell line stably transfected with a cDNA encoding for the human mGlu5a receptor was generated; for the work with mGlu5 Positive Allosteric Modulators (PAMs), a cell line with low receptor expression levels and low constitutive receptor activity was selected to allow the differentiation of agonistic versus PAM activity. Cells were cultured according to standard protocols (Freshney, 2000) in Dulbecco's Modified Eagle Medium with high glucose supplemented with 1 mM glutamine, 10% (vol/vol) heat-inactivated bovine calf serum, Penicillin/Streptomycin, 50 μg/ml hygromycin and 15 μg/ml blasticidin (all cell culture reagents and antibiotics from Invitrogen, Basel, Switzerland). bout 24 hrs before an experiment, 5×104 cells/well were seeded in poly-D-lysine coated, black/clear-bottomed 96-well plates. The cells were loaded with 2.5 μM Fluo-4AM in loading buffer (1×HBSS, 20 mM HEPES) for 1 hr at 37 °C. and washed five times with loading buffer. The cells were transferred into a Functional Drug Screening System 7000 (Hamamatsu, Paris, France), and 11 half logarithmic serial dilutions of test compound at 37 °C. were added and the cells were incubated for 10-30 min. with on-line recording of fluorescence. Following this pre-incubation step, the agonist L-glutamate was added to the cells at a concentration corresponding to EC20 (typically around 80 μM) with on-line recording of fluorescence; in order to account for day-to-day variations in the responsiveness of cells, the EC20 of glutamate was determined immediately ahead of each experiment by recording of a full dose-response curve of glutamate. Responses were measured as peak increase in fluorescence minus basal (i.e. fluorescence without addition of L-glutamate), normalized to the maximal stimulatory effect obtained with saturating concentrations of L-glutamate.

Assay: P70S6K Enzyme Assay: P70S6K inhibitor compounds are diluted and plated in 96 well plates. A reaction mixture including the following components is then added to the compound plate to initiate the enzyme reaction; P70S6K (3 nM, T412E mutant, Millipore) is mixed with 24 uM ATP in an assay buffer containing 100 mM Hepes (pH 7.5), 5 mM MgCl2, 1 mM DTT, 0.015% Brij and 1 uM of the substrate peptide FITC-AHA-AKRRRLSSLRA-OH (derived from the S6 ribosomal protein sequence, FITC=fluorescein isothiocyanate, AHA=6-aminohexanoic acid). The reaction is incubated for 90 min at 25.degree. C., before the addition of 10 mM EDTA to stop the reaction. The proportion of substrate and product (phosphorylated) peptide is analysed on a Caliper Life Sciences Lab Chip 3000, using a pressure of -1.4 psi, and upstream and downstream voltages of -3000 and -700 respectively. Product peaks are resolved before substrate peaks on the resulting chromatograms.

Target: Endothelial lipase (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y5X9
Assay: Enzyme Assay: The enzymatic assay was measured using white, opaque 96-well half area plates. Each well contained 60 uL of assay buffer (50 mM HEPES pH 8.0, 50 mM NaCl and 1 mM CaCl2) and 2 ul of a DMSO solution containing compound of interest. Conditioned media obtained from HT-1080 cells, which were transformed by RAGE technology (Athersys) to overexpress endogenous EL, was added and the reaction was allowed to incubate for 20 min at 37° C. with gentle agitation. The reaction was started by the addition of 20 uL of a 1:4 dilution of vesicles. The final total reaction volume was 100 uL. The reaction rates were measured on a Gemini plate reader with an excitation wavelength of 488 nm and a emission of 530 nm. Readings were taken every 20 seconds for 10 min with agitation between each reading.

Target: Interleukin-1 receptor-associated kinase 4 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NWZ3
Assay: Kinase Assay: The kinase activity of IRAK-4 is determined by its ability to catalyze the phosphorylation of a fluorescent polypeptide substrate. The extent of phosphorylation is measured using the IMAP technology (Molecular Devices) where the phosphorylated fluorescent substrate binds to the large M(III)-based nanoparticles which reduces the rotational speed of the substrate and thus increases its fluorescent polarization (FP). 20 μl reaction mixture contains 10 mM TriHCl, pH 7.2, 0.5 nM GST tagged IRAK-4 (SignalChem), 100 nM fluorescent peptide substrate (RP7030, Molecular Devices), 100 μM ATP, 1 mM DTT, 1 mM MgCl2, and 0.01% Tween 20. The reaction is initiated by the addition of ATP. After incubation for 30 minutes at 25° C., 60 μl of Progressive IMAP Reagent (Molecular Devices) is added to stop the reaction. Change in RP7030's FP is determined by a FP reader (Analyst HT, LH, BioSystems).
