UniProt: O35433
Assay: Functional Assay: The assay was performed as described below, using HEK293 cells transfected with rat TRPV1 (rTRPV1/HEK293). These cells had a geneticin selection marker and were grown in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, penicillin/streptomycin (50 units/mL), and 500 μg/mL geneticin in 5% CO2 at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl, 2 mM KCl, 2 mM MgCl2, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl2. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F127 (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca2+ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λexcitation=488 nm, λemission=540 nm) during challenge with agonist (capsaicin). The IC50 values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 Î¼M with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist.

Assay: PDGFRβ 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 μl per well of kinase buffer containing 200-300 ng purified cytoplasmic domain PDGFRβ protein (Millipore). Following a 60 minute incubation at 30° C., the reactions were washed 2 mls per well PBS-T. 100 μl of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate diluted 1:10,000 in PBS-T was added to the wells for 30 minutes. Following a 2 mis per well wash with PBS-Tween-20, 100 μl of 0-Phenylenediamine Dihydrochloride in phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7-10 minutes as a colorimetric substrate for the peroxidase. The reaction was terminated by the addition of 100 μl of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm.

Assay: FRET-Based Assay: The HCV NS3 protease functions have been extensively studied and are considered as potential targets for antiviral therapy: see for example the many references listed in the introductory section of this application. Therefore, the activity of the compounds of the invention as anti-HCV agents was assessed using a full length HCV NS3 protease.The protease activity of the full length NS3/4a was measured using a FRET-based assay utilizing a peptide substrate derived from the NS4A/B cleavage site (Anaspec) and labelled at one end with a quencher (QXL520) and at the other with a fluorophore (5-FAMsp). NS3/4a (produced in-house by literature methods) was incubated with test compounds and peptide substrate in 50 mM Tris pH8, 20 mM DTT, 1% CHAPS, 10% glycerol and 5% DMSO. The reaction was followed by monitoring the change in fluorescence on a Molecular Devices Gemini plate reader for 30 minutes at room temperature.

Assay: FRET Assay: Methods: An HDM2 FRET assay was developed to assess the compounds' inhibitory activity towards binding of p53 protein. A truncated version of HDM2 with residues 17 to 125 (containing p53 binding surface, Science (1994) 265, 346-355), with N-terminal His and Thioredoxin tag was generated in pET32a expression vector and expressed in E. coli strain BL21(DE3)Rosetta. Protein was purified using Ni-affinity chromatography, followed by size exclusion chromatography using Superdex 75 26/60 column. To assess inhibition of p53 binding to HDM2, a FITC labeled 8-mer peptide (SEQ ID NO:1: Ac-Phe-Arg-Dpr-Ac6c-(6-Br)Trp-Glu-Glu-Leu-NH2; Anal Biochem. 2004 Aug. 1; 331(1):138-46) with strong affinity towards the p53 binding pocket of HDM2 was used.

Assay: In Vitro Assay hPDE10a: Human recombinant PDE10A2 was expressed in Sf9 cells, using a recombinant baculovirus construct containing the full length sequence containing a 6×His sequence following the start Met to allow metal affinity purification of the recombinant protein. Cells were harvested and the phosphodiesterase protein was purified by metal chelate chromatography on Ni-sepharose 6FF.The affinity of the compounds of Formula (I) for phophodiesterases (PDE) was measured by a scintillation proximity assay (SPA). PDE Yttrium Silicate SPA beads allow PDE activity to be measured by direct binding of the primary phosphate groups of non-cyclic AMP or GMP to the beads via a complex iron chelation mechanism. The amount of bound tritiated product ([3H]-AMP) is measured by liquid scintillation counting.The compounds were dissolved and diluted in 100% DMSO in polystyrene plates to a concentration of 100-fold the final concentration in the assay. Human PDE10A enzyme solution (10 uL) was added to 20 μL, of incub

Assay: HTRF Biochemical Assay: The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 uL of 1.11x enzyme and 1.11x substrate in 1x assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 uL of 2x stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction.
