Assay: Measuring Inhibition of the TRPA1 Ion Channel: Compounds of Formula (I) inhibit the TRPA1 channel, as shown by measuring the in vitro inhibition of human TRPA1, provided in data tables shown in Table 2, using the procedure outlined in del Camino et al., The Journal of Neuroscience, 30(45):15165-15174 (Nov. 10, 2010), incorporated herein by reference and summarized below. Data for TRPA1 inhibition was obtained by this method for the indicated compounds of Formula (I), with the relevant data included in Table 2 below. All currents were recorded in whole-cell configuration using EPC-9 and EPC-10 amplifiers and Patchmaster software (HEKA) or similar. Patch pipettes had a resistance of 1.5-3 M and up to 75% of the series resistance was compensated. The standard pipette solution consisted of 140 mM CsAsp, 10 mM EGTA, 10 mM HEPES, 2.27 mM, 20 MgCl2, 1.91 mM CaCl2, and up to 0.3 mM Na2GTP, with pH adjusted to 7.2 with CsOH. In addition, a solution containing 145 mM CsCl, 10 mM HEPES, 10 mM EGTA, and up to 0.3 mM Na2GTP and 1 mM MgCl2 (pH 7.2 adjusted with CsOH) can be used. The standard bath solution contained 150 mM NaCl, 10 mM HEPES, 10 mM glucose, 4.5 mM KCl, 1 mM EGTA, 3 mM MgCl2, with pH adjusted to 7.4 with NaOH. In some instances, 2 mM CaCl2 was added in place of EGTA and the concentration of MgCl2 was reduced to 1 mM.Data were collected either by continuous recordings at −60 mV or by applying voltage ramps from a holding potential of −40 mV every 4 s. Continuous recordings were collected at 400 Hz and digitally filtered off-line at 10 Hz for presentation. Voltage ramps were applied from −100 mV or −80 mV to +100 mV or +80 mV over the course of 400 ms, and data were collected at 10 kHz and filtered at 2.9 kHz. Inward and outward currents were analyzed from the ramps at −80 and 80 mV, respectively. Liquid junction potential correction was not used.

Assay: Class B Enzyme Assay: The Class B enzyme activities were measured in the presence of the test inhibitor in a fluorescence assay against a commercially available substrate consisting of a cephalosporin core linking 7-hydroxycoumarin to fluorescein (CCF2-FA). The enzyme (NDM-1, IMP-1 or VIM-1) and the substrate were diluted in 100 mM KH2PO4 buffer (pH 7) containing 0.005% Tween-20 and 10 μM ZnSO4. In the assay, the final concentration of enzyme was 1 pM, 2 pM and 30 pM for NDM-1, IMP-1 and VIM-1, respectively, and the final concentration of CCF2-FA was 1.25 μM. The test inhibitor was dissolved in dimethylsulfoxide and diluted 1:50 in the assay, resulting in a final concentration range of 20 uM to 0.00063 uM. In a 384-well microplate, the test inhibitor was incubated with the metallo-β-lactamase enzyme and the substrate for 2 hours at 25° C. Fluorescence at 460 nm following excitation at 405 nm was measured. The IC50 value was determined from semi-logarithmic plots of enzyme inhibition versus inhibitor concentration, with a curve generated using a 4-parameter fit.

G. Muccioli, G. Labar, D. M. Lambert, Chem. Bio. Chem. 2008, 9, 2704-2710).The assay was carried out in 384 well assay plates (black with clear bottom, non-binding surface treated, Corning Ref. 3655) in a total volume of 40 μL. Compound dilutions were made in 100% DMSO (VWR Chemicals 23500.297) in a polypropylene plate in 3-fold dilution steps to give a final concentration range in the assay from 25 μM to 1.7 nM. 1 μL compound dilutions (100% DMSO) were added to 19 μL MAGL (recombinant wild-type) in assay buffer (50 mM TRIS (GIBCO, 15567-027), 1 mM EDTA (Fluka, 03690-100 ml)). The plate was shaked for 1 min at 2000 rpm (Variomag Teleshake) and then incubated for 15 min at RT. To start the reaction, 20 μL 4-Nitrophenlyacetate (Sigma N-8130) in assay buffer with 6% EtOH was added. The final concentrations in the assay were 1 nM MAGL and 300 μM 4-Nitrophenylacetate. After shaking (1 min, 2000 rpm) and 5 min incubation at RT, the absorbance at 405 nm was measured for a fist time (Molecular Devices, SpectraMax Paradigm). A second measurement was then done after incubation for 80 min at RT. From the two measurements, the slope was calculated by subtracting the first from the second measurement.

Each well contained 20 μL of assay buffer (50 mM HEPES pH 8.0, 50 mM NaCl and 1 mM CaCl2) and 0.25 μL of a DMSO solution containing a compound of interest. EL or HL (10 μL) was added and allowed to incubate with the compound for 30 min at 37° C. The source of EL was conditioned media obtained from HT-1080 cells that were transformed using RAGE technology (Athersys) to overexpress endogenous EL, and HL was partially purified from conditioned media obtained from COS cells overexpressing HL. The reaction was started by the addition of 10 μL of a 1:10 dilution of vesicles. The final total reaction volume was 20.25 μL. The reaction rates were measured on a Gemini plate reader with an excitation wavelength of 490 nm and an emission wavelength of 530 nm. Readings were taken over a period of 60 minutes, and the slope between 300 and 900 secs of the readout was used to calculate the rate of the reaction.

Assay: Factor XIIa Assay: The effectiveness of a compound of the present invention as an inhibitor of Coagulation Factor XIIa can be determined using a relevant purified serine protease, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Assays were conducted at room temperature or at 37° C. Hydrolysis of the substrate resulted in release of amino trifluoromethylcoumarin (AFC), which was monitored spectrofluorometrically by measuring the increase in emission at 510 nm with excitation at 405 nm. A decrease in the rate of fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as the IC50, the inhibitor concentration causing a 50% decrease in Factor XIIa protease activity.Factor XIIa activity determinations were made in 50 mM HEPES buffer containing 150 mM NaCl, 5 mM CaCl2, and 0.1% PEG 8000 (polyethylene glycol; JT Baker or Fisher Scientific) at pH 7.4. Determinations were made using purified human Factor XIIa at a final concentration of 500 pM (Sekisui Diagnostics) and the synthetic substrate, n-Acetyl-Lys-Pro-Arg-AFC, TFA salt (Sigma #C6608) at a concentration of 100 μM.Activity assays were performed by diluting a stock solution of substrate at least tenfold to a final concentration ≤0.1 Km into a solution containing enzyme or enzyme equilibrated with inhibitor. Times required to achieve equilibration between enzyme and inhibitor were determined in control experiments. Initial velocities of product formation in the absence (Vo) or presence of inhibitor (Vi) were measured. IC50 was determined as the concentration of I yielding Vi=Vo/2.

Assay: In Vitro CBP Inhibition: The CBP-inhibitory activity of the compounds described herein was determined by calculating the IC50. More specifically, CBP inhibitor activity was assayed as follows: CBP was cloned and expressed in E. coli as His-tag protein and purified by Nickel affinity and gel-filtration chromatography. The protein was further characterized as a single band with the correct molecular weight by SDS-PAGE. CBP binding and inhibition is assessed by monitoring the interaction of biotinylated H4-tetraacetyl peptide (AnaSpec, H4K5/8/12/16(Ac), biotin-labeled) with the target using the AlphaScreen technology (Perkin Elmer). In a 384-well ProxiPlate CBP (50 nM final) was combined with peptide (20 nM final) in 50 mM HEPES (pH 7.3), 10 mM NaCl, 0.25 mM TCEP, 0.1% (w/v) BSA, and 0.005% (w/v) Brij-35 either in the presence of DMSO (final 0.4% DMSO) or compound dilution series in DMSO. After 20 min incubation at room temp, Alpha-streptavidin donor beads and Nickel Chelate acceptor beads were added to a final concentration of 5 μg/mL. After 2 hr of equilibration, plates were read on an Envision instrument and the IC50 calculated using a four parameter non-linear curve fit.

Assay: DiscoverX PathHunter Assay: In this assay, U2OS cells express the human TrkA receptor as a fusion with the weakly complementing fragment of B-galactosidase, which DiscoverX calls Prolink (PK); additionally, Shc1 is fused with a larger fragment, which is called Enzyme Acceptor (EA). Activation of the TrkA receptor, upon NGF addition, results in the kinase domain being phosphorylated, resulting in subsequent recruitment of Shc1-EA protein. That recruitment results in an active B-galactosidase enzyme that is detected by addition of a chemiluminescent substrate. The human p75NTR protein was also expressed as a co-receptor for NGF.All reagents were purchased from DiscoverX, except for the receptor agonists (NGF, BDNF, NT3) which were purchased from Peprotech. Cells were expanded and frozen into cryovials, and stored in the vapor phase of liquid nitrogen, and thawed immediately before use. Thawed cells were added to a 384-well plate at 7500 cells/well, and allowed to incubate overnight. Compound at various concentrations was added the following morning and allowed to incubate on cells for 1 h. Then, NGF was added at a concentration sufficient to elicit 80% of a maximal response and allowed to incubate for 3 h at ambient temperature. DiscoverX PathHunter detection reagent was then added and the plate was further incubated for 1 h in the dark. The plate was then read via luminescence on the Perkin Elmer Envision.

Assay: transient human FXR/Gal4-luciferase reporter assay: A Gal4-hFXR fusion construct reporter system was used as the primary assay to characterize compound activity. A construct including 5 copies of the Gal4 promoter response element upstream of a firefly luciferase reporter cDNA was stably expressed in HEK293 cells. This reporter cell line was maintained in Dulbecco's Modified Eagle's medium (DMEM; Gibco) supplemented with 1% penicillin-streptomycin (P/S) solution, 500 μg/ml Zeocin and 10% charcoal/dextran-treated fetal bovine serum (cs-FBS) at 37° C. in a humidified 5% CO2 atmosphere. Another plasmid was constructed in which the human cytomegalovirus promoter in the pcDNA3.1 vector directs the expression of the cDNA encoding a fusion protein comprised of the DNA binding domain from the Gal4 transcription factor fused to the ligand binding domain from human FXR.The day prior to transfection, the reporter cells in culture are detached from the plate with trypsin and plated into a T75 flask at a sufficient density to achieve approximately 90% confluence the next morning. The transfection reagents are prepared by separately diluting 25 μg of the pcDNA3.1-Gal4-FXR plasmid into 1.87 mL of Opti-MEM (Thermo-Fisher), and 40 μL of Lipofectamine 2000 (Thermo-Fisher) into 1.87 mL of Opti-MEM, and then adding the diluted DNA solution into the diluted Lipofectamine 2000 solution and incubating at room temperature for 15-20 minutes. The mixture is further diluted with 10 mL of a solution comprised of DMEM, 10% cs-FBS, and 1% P/S immediately prior to transferring to the cells. The maintenance culture media is aspirated from the cells and the final transfection mixture is added before the cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. This protocol can be scaled up, and the transiently transfected cells can be cryopreserved in an assay-ready format.For compound testing, 100 nL of the compounds (serial dilutions in DMSO) are dispensed with an Echo acoustic dispenser (Labcyte) into the wells of a Corning/Costar clear bottom 384-well white plate. The transfected cells are harvested, counted, and diluted such that 10-25,000 cells in 25 μL are plated into each well of the 384-well compound assay plate. The compound-treated cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. The next morning 25 μL of Steady-Glo (Promega) are added to each well of the plate, the mixture is incubated for 15 min. with shaking, and luminescence is measured on an Envision (Perkin Elmer) plate reader. Background counts from cells treated with DMSO alone are subtracted from all raw counts, and the corrected values are converted to a percentage of the control response attained with 8 μM GW-4064. These data are fit to a 4-parameter log agonist-response equation to calculate an EC50 value.

Dose-response measurements were assayed by either creating 1:10 serial dilutions in DMSO to produce a 7 point curve or by making 1:3 serial dilutions in DMSO to produce 11 point curves. The top concentrations were adjusted depending on the potency of the compounds and subsequent dilution in reaction buffer yielded a final DMSO concentration≤2%.
