Assay: Inhibition Assay: LOX and LOXL2: Lysyl oxidase (LOX) is an extracellular copper dependent enzyme which oxidizes peptidyl lysine and hydroxylysine residues in collagen and lysine residues in elastin to produce peptidyl alpha-aminoadipic-delta-semialdehydes. This catalytic reaction can be irreversibly inhibited by β-aminopropionitrile (BAPN) that binds to the active site of LOX (Tang S. S., Trackman P. C. and Kagan H. M., Reaction of aortic lysyl oxidase with beta-aminoproprionitrile. J Biol Chem 1983; 258: 4331-4338). There are five LOX family members; these are LOX, LOXL1, LOXL2, LOXL3 and LOXL4. LOX and LOXL family members can be acquired as recombinant active proteins from commercial sources, or extracted from animal tissues like bovine aorta, tendons, pig skin; or prepared from cell cultures. The inhibitory effects of the compounds of the present invention were tested against the given LOX-LOXL preparation using a high-throughput coupled colorimetric method (Holt A. and Palcic M., A peroxidase-coupled continuous absorbance plate-reader assay for flavin monoamine oxidases, copper-containing amine oxidases and related enzymes. Nat. Protoc. 2006; 1: 2498-2505). The assay was developed using either 384 or 96 well format. Briefly, in a standard 384 well plate assay 25 μL of a dilution of any of the isoenzymes and orthologues in 1.2 M urea, 50 mM sodium borate buffer (pH 8.2) were added into each well in the presence of 1 μM mofegiline and 0.5 mM pargyline (to inhibit SSAO and MAO-B and MAO-A, respectively). Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 11 data points, typically in the micromolar or nanomolar range after incubation with the enzyme for 30 min at 37° C. Twenty five L of a reaction mixture containing twice the KM concentration of putrescine (Sigma Aldrich, e.g. 20 mM for LOX, or 10 mM for LOXL2 and LOXL3), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 1.2 M urea, 50 mM sodium borate buffer (pH 8.2) were then added to the corresponding wells. The above volumes were doubled in the case of 96 wells plate.

Assay: Human LOXL2 CCM Assay: LOXL2 amine oxidase activity was evaluated by measuring Amplex Red fluorescence using 10-20× concentrated conditioned media (non BSA-containing) from CHO cells stably expressing human LOXL2. To assay for amine oxidase activity, 10 μL of the concentrated conditioned media was incubated with 2 μL of test compound in DMSO and 73 μL Assay Buffer (50 mM Borate Buffer, pH8) for 2 h at 37° C. After the 2 h incubation, 5 μL of 10 mM 1,5-Diaminopentane (DAP) diluted in Assay Buffer and 10 μL of Amplex Red Mix (8.5 μL Assay Buffer+0.5 μL of 10 mM Amplex Red+1 μL of 500 U/ml Horseradish Peroxidase) were added and the plate mixed and immediately placed on the FlexStation for fluorescence measurements. Fluorescence was read in kinetic mode every 2 min for 0.5-1 hour at excitation=544 and emission=590. The amine oxidase activity was calculated from the slope of the linear portion of the curve. Wells containing vehicle (DMSO) represented maximum activity and were set to 0% inhibition and wells containing 100 μM βAPN (3-aminopropionitrile) represented no activity and were set to 100% inhibition.

Assay: Biochemical Assay: USP28: The assay was performed in a final volume of 20 uL in assay buffer containing 20 mM Tris-HCl (pH 8.0, (1M Tris-HCl, pH 8.0 solution; Corning 46-031-CM)), 2 mM CaCl2 (1M Calcium Chloride solution; Sigma #21114) 2 mM BME (2-Mercaptoethanol; Sigma 63689-25ML -F), 0.01% Prionex (0.22 uM filtered, Sigma #G-0411), and 0.01% Triton X-100. Stock compound solutions were stored at â20° C. as 10 mM in DMSO. Up to 1 month prior to the assay, 2 mM test compounds were pre-dispensed into assay plates (Black, low volume; Corning #3820) and frozen at â20° C. Prestamped assay plates were allowed to come to room temperature on the day of the assay. For the screen, 100 nL of 2 mM was pre-dispensed for a final screening concentration of 10 uM (DMSO(fc)=0.5%). Enzyme (USP28, construct USP28 (USP28-5(1-1077)-TEV-6*His; LifeSensors) concentration and incubation times were optimized for the maximal signal-to -background while maintaining initial velocity conditions at a fixed substrate concentration. The final concentration of the enzyme in the assay was 400 pM. Final substrate (Ub-Rh110; Ubiquitin -Rhodamine 110, R&D Systems #U-555) concentration was 25 nM with [Ub-Rh110] Km. 10 uL of 2x enzyme was added to assay plates (pre-stamped with compound) either simultaneously with 2xUb-Rh110 or preincubated with USP28 40 minutes prior to the addition of 10 uL of 2xUb -Rh110 to compound plates. Plates were incubated stacked for 90 minutes at room temperature before fluorescence was read on the Envision (Excitation at 485 nm and Emission at 535 nm; Perkin Elmer) or on the PheraSTAR (Excitation at 485 nm and Emission at 535 nm; BMG Labtech).

Assay: Inhibition Assay: LOX and LOXL2: Lysyl oxidase (LOX) is an extracellular copper dependent enzyme which oxidizes peptidyl lysine and hydroxylysine residues in collagen and lysine residues in elastin to produce peptidyl alpha-aminoadipic-delta-semialdehydes. This catalytic reaction can be irreversibly inhibited by β-aminopropionitrile (BAPN) that binds to the active site of LOX (Tang S. S., Trackman P. C. and Kagan H. M., Reaction of aortic lysyl oxidase with beta-aminoproprionitrile. J Biol Chem 1983; 258: 4331-4338). There are five LOX family members; these are LOX, LOXL1, LOXL2, LOXL3 and LOXL4. LOX and LOXL family members can be acquired as recombinant active proteins from commercial sources, or extracted from animal tissues like bovine aorta, tendons, pig skin; or prepared from cell cultures. The inhibitory effects of the compounds of the present invention were tested against the given LOX-LOXL preparation using a high-throughput coupled colorimetric method (Holt A. and Palcic M., A peroxidase-coupled continuous absorbance plate-reader assay for flavin monoamine oxidases, copper-containing amine oxidases and related enzymes. Nat. Protoc. 2006; 1: 2498-2505). The assay was developed using either 384 or 96 well format. Briefly, in a standard 384 well plate assay 25 μL of a dilution of any of the isoenzymes and orthologues in 1.2 M urea, 50 mM sodium borate buffer (pH 8.2) were added into each well in the presence of 1 μM mofegiline and 0.5 mM pargyline (to inhibit SSAO and MAO-B and MAO-A, respectively). Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 11 data points, typically in the micromolar or nanomolar range after incubation with the enzyme for 30 min at 37° C. Twenty five L of a reaction mixture containing twice the KM concentration of putrescine (Sigma Aldrich, e.g. 20 mM for LOX, or 10 mM for LOXL2 and LOXL3), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 1.2 M urea, 50 mM sodium borate buffer (pH 8.2) were then added to the corresponding wells. The above volumes were doubled in the case of 96 wells plate.

Target: Coagulation factor XI (SINGLE PROTEIN), Homo sapiens
UniProt: P03951
Assay: In Vitro Assay: The effectiveness of compounds of the present invention as inhibitors of the coagulation Factors XIa, VIIa, IXa, Xa, XIIa, plasma kallikrein or thrombin, can be determined using a relevant purified serine protease, respectively, 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 the release of pNA (para nitroaniline), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nm, or the release of AMC (amino methylcoumarin), which was monitored spectrofluorometrically by measuring the increase in emission at 460 nm with excitation at 380 nm. A decrease in the rate of absorbance or 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 inhibitory constant, Ki.

Assay: Biochemical Assay: USP28: The assay was performed in a final volume of 20 uL in assay buffer containing 20 mM Tris-HCl (pH 8.0, (1M Tris-HCl, pH 8.0 solution; Corning 46-031-CM)), 2 mM CaCl2 (1M Calcium Chloride solution; Sigma #21114) 2 mM BME (2-Mercaptoethanol; Sigma 63689-25ML -F), 0.01% Prionex (0.22 uM filtered, Sigma #G-0411), and 0.01% Triton X-100. Stock compound solutions were stored at â20° C. as 10 mM in DMSO. Up to 1 month prior to the assay, 2 mM test compounds were pre-dispensed into assay plates (Black, low volume; Corning #3820) and frozen at â20° C. Prestamped assay plates were allowed to come to room temperature on the day of the assay. For the screen, 100 nL of 2 mM was pre-dispensed for a final screening concentration of 10 uM (DMSO(fc)=0.5%). Enzyme (USP28, construct USP28 (USP28-5(1-1077)-TEV-6*His; LifeSensors) concentration and incubation times were optimized for the maximal signal-to -background while maintaining initial velocity conditions at a fixed substrate concentration. The final concentration of the enzyme in the assay was 400 pM. Final substrate (Ub-Rh110; Ubiquitin -Rhodamine 110, R&D Systems #U-555) concentration was 25 nM with [Ub-Rh110] Km. 10 uL of 2x enzyme was added to assay plates (pre-stamped with compound) either simultaneously with 2xUb-Rh110 or preincubated with USP28 40 minutes prior to the addition of 10 uL of 2xUb -Rh110 to compound plates. Plates were incubated stacked for 90 minutes at room temperature before fluorescence was read on the Envision (Excitation at 485 nm and Emission at 535 nm; Perkin Elmer) or on the PheraSTAR (Excitation at 485 nm and Emission at 535 nm; BMG Labtech).
