Target: cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y233
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.

UniProt: P43405
Assay: Homogeneous Time-Resolved Fluorescence (HTRF) Assay: A recombinant GST-hSYK fusion protein was used to measure potency of compounds to inhibit human Syk activity. The recombinant human GST-SYK (Carna Biosciences #08-176) (5 μM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for Syk was added with magnesium (5 mM final concentration) and ATP (25 μM final concentration). Final volume of the reaction was 10 μL. Phosphorylation of the peptide was allowed to proceed for 45' at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #AD0161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5, 40 mM EDTA, 0.01% tween 20. Final volume of the quenching solution was 10 μL. The resulting HTRF signal was measured after 30 minutes on an EnVision (Perkin-Elmer) reader using a time-resolved fluorescence protocol.

Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

If wavelength correction is available, set to 540 nm or 570 nm. If wavelength correction is not available, subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.

Assay: In Vitro Radioactive Assays of CETP-Catalyzed CE and TG Transfer (RTA Assay): Radiolabeled donor particles are generated by first combining 100 μl of 200 μM butylated hydroxyl toluene in CHCl3, 216 μL of 21.57 mM DOPC in EtOH, and either 500 μCi [3H]-triolein (Perkin Elmer #NET-431) or 500 μCi [3H]-cholesteryl oleate (GE #TRK886) in a glass tube. Reagents are mixed, dried under nitrogen, and then resuspended in 2 mL of 50 mM Tris, 27 μM EDTA at pH 7.4. After a brief vortex, the solution is sonicated until clear and mixed with 20 mL of fresh human serum. The mixture is incubated overnight at 37° C. The [3H] labeled LDL substrate is separated at 1.063 g/ml density by sequential ultracentrifugal flotation in NaBr according to the method by (Havel, Eder et al. 1955; Chapman, Goldstein et al. 1981). Once isolated the particles are dialyzed 3× in CETP buffer (50 mM Tris, pH 7.4, 100 mM NaCl, 1 mM EDTA). Human HDL is purchased from Intracel and used as the acceptor particles. Transfer assays are performed in a 96 or 384-well v-bottom polypropylene plate. For the RTA using recombinant CETP (2% RTA), an assay cocktail is prepared with the final concentrations 128 μg/mL HDL, 20 nM rCETP, 2% human serum, and 1×CETP buffer. 1 μL of each test compound diluted in DMSO is added to 47 μL of assay cocktail per well and incubated at 37° C. for 1 hour. To initiate the transfer reaction, 2 μL radiolabeled LDL is added. After an additional 60 min of incubation at 37° C., the transfer action is terminated by precipitation of LDL with an equal volume of 20% W/V PEG 8000. The plates are centrifuged at 2000 rpm for 30 minutes at 4° C. A 40 μL aliquot of the HDL-containing supernatant is transferred to a Packard Optiplate™ with 200 μL of MicroScint™ 20. After mixing, plates are counted by liquid scintillation.

Assay: PARP Enzyme Inhibition Assay: PARP1 assay was conducted in PARP assay buffer containing 50 mM Tris pH 8.0, 1 mM DTT, 4 mM MgCl2. PARP reactions contained 1.5 uM [3H]-NAD+ (1.6 uCi/mmol), 200 nM biotinylated histone H1, 200 nM sIDNA, and 1 nM PARP enzyme. Auto reactions utilizing SPA bead-based detection were carried out in 100 uL volumes in white 96 well plates. Reactions were initiated by adding 50 ul of 2xNAD+ substrate mixture to 50 uL of 2x enzyme mixture containing PARP and DNA. These reactions were terminated by the addition of 150 uL of 1.5 mM benzamide (~1000-fold over its IC50). 170 uL of the stopped reaction mixtures were transferred to streptavidin Flash Plates, incubated for 1 hour, and counted using a TopCount microplate scintillation counter.

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: IMAP-FP Assay: Activated ERK2 activity was determined in an IMAP-FP assay (Molecular Devices). Using this assay format, the potency (IC50) of each compound was determined from a 10 point (1:3 serial dilution, 3 uM starting compound concentration) titration curve using the following outlined procedure. To each well of a black Corning 384-well plate (Corning Catalog #3575), 7.5 nL of compound (3333 fold dilution in final assay volume of 25 uL) was dispensed, followed by the addition of 15 uL of kinase buffer (tween containing kinase buffer, Molecular Devices) containing 0.0364 ng/mL (0.833 nM) of phosphorylated active hERK2 enzyme. Following a 15 minute compound & enzyme incubation, each reaction was initiated by the addition of 10 uL kinase buffer containing 2.45 uM ERK2 IMAP substrate peptides (2.25 uM-unlabeled IPTTPITTTYFFFK-COOH and 200 nM-labeled IPTTPITTTYFFFK-SFAM (5-carboxyfluorescein)-COOH), and 75 uM ATP. The final reaction in each well of 25 uL consists of 0.5 nM hERK2, 900 nM unlabeled peptide, 80 nM labeled-peptide, and 30 uM ATP.
