Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

Assay: Recombinant SSAO/VAP-1 Inhibition Assay in Rat Fat: Abdominal fat from BALB/c mice, Wistar or Sprague Dawley rats, which are tissues enriched with SSAO/VAP-1-were surgically removed. For every gram of animal abdominal fat tissue, 1 mL of 0.1 M NaPO4 buffer (pH 7.4) was added. Tissues were homogenized using IKA Ultra-Turrax T 10 homogenizer for 3 min, homogenate was centrifuged for 15 min at 3000×g. The middle layer (clear supernatant) was removed without disturbing the top layer (high fat content) or the debris on the bottom of the tube. SSAO/VAP-1 activity was determined by checking the fluorescent signal. Km/Vmax values were determined and the fat homogenate was aliquoted and stored at −80 °C until assays were performed. Assay was performed in a similar fashion as for human SSAO/VAP-1 (Example 5) except, the substrate (benzylamine) concentrations used for mouse fat homogenate and rat fat homogenate were 80 μM and 30 μM respectively: Briefly, in a standard 96 well plate assay 50 μL of purified human SSAO/VAP-1 (0.25 μg/mL) in 0.1 M NaPO4 buffer (pH 7.4) was added into each well. Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 4-9 data points, typically in the micromolar or nanomolar range after incubation with human SSAO/VAP-1 for 30 min at 37 °C. After 30 min incubation, 50 μL of the reaction mixture containing 600 μM benzylamine (Sigma Aldrich), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 0.1 M NaPO4 buffer (pH 7.4) were added to the corresponding well. The fluorescence unit (RFU) was read every 2.5 min for 30 min at 37 °C. excitation 565 nm and emission 590 (Optima; BMG labtech). The slope of the kinetics for each well was calculated using MARS data analysis software (BMG labtech) and this value was used to deduce the IC50 value (Dotmatics).

Assay: Thallium Flux Assay: The ROMK channel functional thallium flux assay is performed in 384 wells, using the FLIPR-Tetra instrument. HEK-hKir1.1 cells are seeded in Poly-D-Lysine microplates and kept in a 37° C.-10% CO2 incubator overnight. On the day of the experiment, the growth media is replaced with the FluxOR™ reagent loading buffer and incubated, protected from light, at ambient temperature (23-25° C.) for 90 min. The loading buffer is replaced with assay buffer±test compound followed by 30 min incubation at ambient temperature, where the Thallium/Potassium stimulant is added to the microplate. The fluorescence intensity of wells containing 3 μM of a standard control ROMK inhibitor of the present invention is used to define the ROMK-sensitive component of thallium flux. Fluorescence in the presence of test compounds is normalized to control values to provide % fluorescence change. IC50 values represent the concentration of compound that inhibits 50% of the ROMK thallium flux signal.

TR-FRET is measured by excitation of the terbium-donor with 340 nm light and subsequent (delay time 100 μs) measurement of terbium and fluorescein emission at 495 nm and 520 nm, respectively, over a time window of 1000 μs. The measurement is repeated 10 times for fluorescein and 10 times for terbium emission with a 2000 μs time window between repeats. TR-FRET measurements are performed on a Biomek Synergy plate. The TR-FRET signal is calculated as the emission-ratio at 520 nm over 495 nm.

Target: Protein deacetylase HDAC6 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9UBN7
Assay: Enzyme Assay: Enzyme activity of HDAC1,3 is determined using the substrate Ac-Lys-Tyr-Lys(Ac)-AMC while the enzyme activity of HDAC6 is assayed using the substrate Boc-lys(Ac)-AMC. The reaction is carried out in flat-bottom, 96-well, or 384-well microplates. After the substrate was deacetylated by HDACs, the product AMC which was obtained from hydrolysis by trypsin can generate fluorescence signal. Measurement is taken in using an multilabe plate reader a 355 nm excitation filter and a 460 nm emission filter. The initial rate of fluorescence should accurately reflect the rate of product formation and enzyme activity. Sample processing: The sample was dissolved in DMSO and kept at a low temperature. DMSO in the final system is limited under a low concentration which won't affect the enzyme activity.

Assay: cAMP Assay: CHO cells expressing human CB1 or CB2 receptors are seeded 17-24 hours prior to the experiment 50.000 cells per well in a black 96 well plate with flat clear bottom (Corning Costar #3904) in DMEM (Invitrogen No. 31331), 1×HT supplement, with 10% fetal calf serum and incubated at 5% CO2 and 37° C. in a humidified incubator. 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.
