Assay: Radioligand Binding Assay: To perform the competition binding assay, thawed membrane homogenate was added to each well of a 96-well plate (20 ug/well). The experimental compounds were serially diluted in 100% DMSO and added to each row of the assay plate to achieve desired compound concentrations, keeping the DMSO concentration in the assay plate at 1.33% of the final reaction volume. Next, 3H Ro 25-6981 (4 nM) was added to the assay plate. After incubation for 1 hr at room temperature, the membrane bound radioligand was harvested on to GF/B filter plates (treated with 0.5% PEI for 1 hr at room temperature). The filter plates were dried at 50° C. for 20 mins, incubated with microscint 20 for 10 minutes and finally, the counts were read on TopCount (Perkin Elmer). Non-specific binding was determined using MK-0657 (the preparation of this compound is described as example 1 in WO 2004 108705 (40 uM).

Assay: Biochemical Assay: The autoparsylation activity of the TNKS 1/2 or PARP1/2 enzymes was measured by the liquid chromatography-mass spectrometry (LC/MS) detection of nicotinamide as readout. Compound activity in inhibiting the TNKS and PARP autoparsylation was evaluated by IC50 measurements. In the compound screening assays, the reaction is composed of 5 uL of compound in 8-point serial dilutions with concentrations ranging from 0.0086 to 18.75 uM, 20 nM of purified enzyme, and 250 uM of p-NAD+ in the 1x Assay Buffer. After 60 min incubation at room temperature, the reactions were quenched by the addition of 10 uL of 5x quenching solution (20% formic acid and 500 nM [d]-nicotinamide in water). For the background control wells, 10 uL of the 5x quenching solution per well was added prior to the addition of p-NAD+. The % Inhibition was calculated as: (Control-Sample)/(Control-Background)*100. "Control" is the average value of 8 wells without compound; and "Background" is the average of 8 wells mixed with 5x quenching solution measured prior to initiation of the reaction.

Assay: Inhibition of Specific Binding to the hERG-Receptor (HERGBD): After thawing on the day of the assay, the membrane suspension was diluted further with 20 mM HEPES/0.1 mM KCl/pH 7.2.The incubation mixture of 200 μl contained 1.5 nmol/l 3H-Dofetilide, optimized amount of membrane preparation, 20 mM HEPES/0.1 mM KCl/(pH 7.2) and inhibitor in 1% DMSO. Nonspecific binding was estimated in the presence of 10 M Dofetilide. The samples were incubated for 90 min. at RT.Binding was terminated by filtration of the incubated membrane preparations using Filtermat B (Pharmacia, Uppsala Sweden) and a Micro Cell Harvester (Skatron, Lier, Norway). The Filtermat B had been presoaked with 1% polyethylen imine and carefully washed with 0.05 M Tris/HCl-buffer pH=7.7 after the filtration to separate free and bound radioactivity. The filters were counted in a scintillation counter (Betaplate 1205, Berthold, Wildbad, Germany) in order to determine the specific binding of [3H]-Dofetilide.

Assay: Biochemical Assay: The autoparsylation activity of the TNKS 1/2 or PARP1/2 enzymes was measured by the liquid chromatography-mass spectrometry (LC/MS) detection of nicotinamide as readout. Compound activity in inhibiting the TNKS and PARP autoparsylation was evaluated by IC50 measurements. In the compound screening assays, the reaction is composed of 5 uL of compound in 8-point serial dilutions with concentrations ranging from 0.0086 to 18.75 uM, 20 nM of purified enzyme, and 250 uM of p-NAD+ in the 1x Assay Buffer. After 60 min incubation at room temperature, the reactions were quenched by the addition of 10 uL of 5x quenching solution (20% formic acid and 500 nM [d]-nicotinamide in water). For the background control wells, 10 uL of the 5x quenching solution per well was added prior to the addition of p-NAD+. The % Inhibition was calculated as: (Control-Sample)/(Control-Background)*100. "Control" is the average value of 8 wells without compound; and "Background" is the average of 8 wells mixed with 5x quenching solution measured prior to initiation of the reaction.

Assay: DAO Inhibition Assay: Recombinant human DAO (2.4 μg/mL) was used as source of DAO enzyme activities. The assay was performed as described in the method for human SSAO/VAP-1 (Example 5) except the substrate used was 200 μM putrescine, and the control wells contained 10 μM aminoguanidine instead of Mofegiline: 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.

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).

Target: Tyrosine-protein kinase JAK2 (SINGLE PROTEIN), Homo sapiens
UniProt: O60674
Assay: In vitro JAK Kinase Assay: The catalytic domains of human JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a. 781-1124) with an N-terminal His tag were expressed using baculovirus in insect cells and purified. The catalytic activity of JAK1, JAK2 or JAK3 was assayed by measuring the phosphorylation of a biotinylated peptide. The phosphorylated peptide was detected by homogenous time resolved fluorescence (HTRF). IC50s of compounds were measured for each kinase in the 40 microL reactions that contain the enzyme, ATP and 500 nM peptide in 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL (0.01%) BSA. For the 1 mM IC50 measurements, ATP concentration in the reactions was 1 mM. Reactions were carried out at room temperature for 1 hr and then stopped with 20 μL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20 in assay buffer (Perkin Elmer, Boston, Mass.).

UniProt: P42345
Assay: Cellular Assay: Assay d) MDA-MB-468 cells (human breast adenocarcinoma ##ATCC HTB 132) were seeded at 1500 cells/well in 40 μl of DMEM containing 10% FBS and 1% glutamine into Greiner 384 well black flat-bottomed plates. Cell plates were incubated for 18 h in a 37° C. incubator before dosing with compounds of formula (I) in 100% DMSO using acoustic dispensing. Compounds were dosed in a 12 point concentration range into a randomised plate map. Control wells were generated either by dosing of 100% DMSO (max signal) or addition of a reference compound (a PI3K-β inhibitor) that completely eliminated the pAKT signal (min control). Plates were incubated, at 37° C. for 2 h, cells were then fixed by the addition of 10 μl of a 3.7% formaldehyde solution. After 30 minutes the plates were washed with PBS using a Tecan PW384 plate washer. Wells were blocked and cells permeabilised with the addition of 40 μl of PBS containing 0.5% Tween20 and 1% Marvel™ (dried milk powder) and incubated for 60 minutes at r.t. The plates were washed with PBS containing 0.5% (v/v) Tween20 and 20 μl rabbit anti-phospho AKT Ser473 (Cell Signalling Technologies, #3787) in same PBS-Tween+1% Marvel™ was added and incubated overnight at 4° C. Plates were washed 3 times with PBS 0.05% Tween 20 using a Tecan PW384. 20 μl of secondary antibody Alexa Fluor 488 anti-Rabbit (Molecular Probes, #A11008) diluted in PBS+0.05% Tween20 containing 1% Marvel™ was added to each well and incubated for 1 h at r.t. Plates were washed three times as before then 20 μl PBS added to each well and plates sealed with a black plate sealer. The plates were read on an Acumen plate reader as soon as possible, measuring green fluorescence after excitation with 488 nm laser.
