Target: High affinity nerve growth factor receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P04629
Assay: Cell Based Assay: TRKA co-expressed with p75: The assays are based upon DiscoveRx's proprietary Enzyme Fragment Complementation (EFC) technology. In the case of the TRK cell lines, the enzyme acceptor (EA) protein is fused to a SH2 protein and the TRK receptor of interest has been tagged with a Prolink tag. Cryopreserved PathHunter cells are used from either in-house produced batches or bulk batches bought directly from DiscoveRx. Cryopreserved cells are resuscitated, spun 1000 rpm for 4 min to remove freezing media, and resuspended in MEM+0.5% horse serum (both Invitrogen) to 5e^5 cells/ml. The cells are then plated using a Multidrop into Greiner white tissue culture treated plates at 20 μl/well and incubated for 24 h at 37 °C., 5% CO2, high humidity. On the day of the assay, the cell plates are allowed to cool to room temperature for 30 min prior to the assay. 4 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

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: BACE Assay: For each compound being tested, the BACE activity was monitored in a fluorescence quenching assay (FRET) using the ectodomain of BACE (aa 1-454) fused to a myc-his tag and secreted from HEK293/BACEect. cells into OptiMEM (Invitrogen) as enzyme source and a substrate peptide derived from the APP-Swedish mutation which possesses a Cy3-fluorophore at the N-terminus and a Cy5Q-quencher at the C-terminus (Cy3-SEVNLDAEFK-Cy5Q-NH2; Amersham). The substrate was dissolved at 1 mg/mL in DMSO.The assay was performed in the presence of 5 μl OptiMEM (supernatant collected over 24 hours and cleared from cellular debris by centrifugation) containing the ectodomain of BACE, 25 μl water containing the desired concentration of test compound and 1% DMSO, 1 μM substrate peptide, 20 mM NaOAc, pH 4.4 and 0.04% Triton-X100 in a total assay volume of 50 μl in a 384 well plate. In general, 25 μl of compound dilution were given to the plate followed by the addition of 10 μl of BACE containing OptiMEM diluted 1:2 in water with 0.2% Triton X-100. The reaction was started with the addition of 15 μl substrate in NaOAc buffer. The reaction was incubated at 30° C. in a fluorimeter and the cleavage of the substrate was recorded as kinetic for 60 min. at ex: 530 nm, em: 590 nm. Blank wells containing either no inhibitor or no enzyme were included on each plate.The intensity of fluorescence was regressed against time in order to derive velocities of reaction in all 384 wells. These velocities were used for calculating percent inhibition using an uninhibited control containing 1% DMSO and a fully inhibited control incubations performed in the absence of enzyme. IC50 values were calculated by fitting percent inhibition vs. inhibitor concentration using standard software like GraphPadPrism.

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.

On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

The final assay volume was 30 L prepared from 15 L additions of enzyme and substrates (fluoresceinated peptide and ATP) and test compounds in assay buffer (20 mM HEPES pH 7.2, 10 mM MgCl2, 0.015% Brij 35 and 4 mM DTT). The reaction was initiated by the combination of IRAK4 with substrates and test compounds. The reaction mixture was incubated at room temperature for 60 min. and terminated by adding 45 μL of 35 mM EDTA to each sample. The reaction mixture was analyzed on the Caliper LABCHIP® 3000 (Caliper, Hopkinton, Mass.) by electrophoretic separation of the fluorescent substrate and phosphorylated product. Inhibition data were calculated by comparison to no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentrations of reagents in the assays are ATP, 500 μM; FL-IPTSPITTTYFFFKKK peptide 1.5 μM; IRAK4, 0.6 nM; and DMSO, 1.6%.

Assay: Kinase HotSpotâ¿¢ Assay: Compounds were profiled for FGFR inhibition activity at Reaction Biology Corporation (Malvern, Pa.) with their Kinase HotSpot assay. See, Anastassiadis et al., 2011, Comprehensive assay of kinase catalytic activity reveals features of kinase inhibitor selectivity. Nat Biotechnol 29, 1039-1045.Recombinant FGFR1 (2.5 nM), FGFR2 (1 nM), FGFR3 (5 nM), or FGFR4 (12 nM) (Invitrogen) was prepared as a mixture with substrate KKKSPGEYVNIEFG (SEQ ID NO:1) (20 uM, FGFR1 substrate); and Poly [E,Y]4:1 (0.2 mg/ml, FGFR2,3,4 substrate)] in kinase reaction buffer (20 mM HEPES-HCl, pH 7.5, 10 mM MgCl2, 2 mM MnCl2, 1 mM EGTA, 0.02% Brij35, 0.1 mM Na3VO4, 0.02 mg/ml BSA, 2 mM DTT, and 1% DMSO). Compound was added to the enzyme/substrate mixture using acoustic technology (Labcyte Echo 550, Sunnyvale, Calif.) (see, Olechno et al., 2006, Improving IC50 results with acoustic droplet ejection. JALA 11, 240-246) and pre-incubated for 0, 15, or 60 minutes at room temperature. After compound pre-incubation, a mixture of ATP (Sigma-Aldrich) and 33P-γ-ATP (PerkinElmer) was added to a final concentration of 10 uM to initiate kinase reactions. Reactions were incubated for 120 minutes at room temperature and then spotted onto Whatman P81 ion exchange filter paper. Unbound phosphate was removed by extensively washing filters in 0.75% phosphoric acid.
