UniProt: P02753
Assay: TR-FRET Assay: TR-FRET assay for retinol-induced RBP4-TTR interaction Binding of a desired RBP4 antagonist displaces retinol and induces hindrance for RBP4-TTR interaction resulting in the decreased FRET signal (FIG. 7). Bacterially expressed MBP-RBP4 and untagged TTR were used in this assay. For the use in the TR-FRET assay the maltose binding protein (MBP)-tagged human RBP4 fragment (amino acids 19-201) was expressed in the Gold(DE3)pLysS E. coli strain (Stratagene) using the pMAL-c4x vector. Following cell lysis, recombinant RBP4 was purified from the soluble fraction using the ACTA FPLC system (GE Healthcare) equipped with the 5-ml the MBP Trap HP column. Human untagged TTR was purchased from Calbiochem. Untagged TTR was labeled directly with Eu3+ Cryptate-NHS using the HTRF Cryptate Labeling kit from CisBio following the manufacturer's recommendations. HTRF assay was performed in white low volume 384 well plates (Greiner-Bio) in a final assay volume of 16 ul per well. The reaction buffer contained 10 mM Tris-HCl pH 7.5, 1 mM DTT, 0.05% NP-40, 0.05% Prionex, 6% glycerol, and 400 mM KF. Each reaction contained 60 nM MBP-RBP4 and 2 nM TTR-Eu along with 26.7 nM of anti-MBP antibody conjugated with d2 (Cisbio). Titration of test compounds in this assay was conducted in the presence of 1 uM retinol. All reactions were assembled in the dark under dim red light and incubated overnight at +4° C. wrapped in aluminum foil. TR-FRET signal was measured in the SpectraMax M5e Multimode Plate Reader (Molecular Device). Fluorescence was excited at 337 nm and two readings per well were taken: Reading 1 for time-gated energy transfer from Eu(K) to d2 (337 nm excitation, 668 nm emission, counting delay 75 microseconds, counting window 100 microseconds) and Reading 2 for Eu(K) time-gated fluorescence (337 nm excitation, 620 nm emission, counting delay 400 microseconds, counting window 400 microseconds).

Assay: Recombinant SSAO/VAP-1 Inhibtion Assay: Briefly, HMEC cell expressing human SSAO/VAP-1 were grown in several 10 cm petri dishes, once the cells reached 100% confluency, cells were harvested and homogenates were prepared. Cells were washed twice with 5 mL of chilled HES buffer (20 mM HEPES, 1 mM EDTA, 250 mM sucrose, pH 7.4). HES buffer containing 1× protease inhibitor (Sigma Aldrich) and added and cells were incubated on ice for 3 min. Buffer was removed and cells were scraped and transferred to a centrifuge tube. Cell lysates were prepared by passing through 23 G needle for, 10 times and followed by 27 G needle for 10 times. Alternatively the cell lysates were prepared by using IKA Ultra-Turrax T 10 homogenizer for 3 min for every 10 mL of cell suspensions. Cells were then spun for 5 min at 300×g. The clear supernatant was transferred to new centrifuge tube and stored at −80 °C. until colorimetric assay was performed. Prior to the assay, 0.5 mM pargyline was added in order to inhibit any residue MAO activities. Briefly, 50 μL of cell lysate was incubated with test compounds for 30 min at 37 °C. Reaction mixtures were added and kinetic was read as described in detail in Example 5: 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).
