Target: Tyrosine-protein kinase SYK (SINGLE PROTEIN), Homo sapiens
UniProt: P43405
Assay: Homogeneous Time-Resolved Fluorescence (HTRF) Assay: A recombinant GST-hSyk fusion protein was used to measure potency of compounds to inhibit human Syk activity. The recombinant human GST-Syk (Carna Biosciences #08-176) (5 pM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for Syk was added with magnesium (5 mM final concentration) and ATP (25 uM final concentration). Final volume of the reaction was 10 uL. Phosphorylation of the peptide was allowed to proceed for 45x at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #AD0161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5.

Target: Interleukin-1 receptor-associated kinase 4 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NWZ3
Assay: Kinase Assay: The kinase activity of IRAK-4 is determined by its ability to catalyze the phosphorylation of a fluorescent polypeptide substrate. The extent of phosphorylation is measured using the IMAP technology (Molecular Devices) where the phosphorylated fluorescent substrate binds to the large M(III)-based nanoparticles which reduces the rotational speed of the substrate and thus increases its fluorescent polarization (FP). 20 μl reaction mixture contains 10 mM TriHCl, pH 7.2, 0.5 nM GST tagged IRAK-4 (SignalChem), 100 nM fluorescent peptide substrate (RP7030, Molecular Devices), 100 μM ATP, 1 mM DTT, 1 mM MgCl2, and 0.01% Tween 20. The reaction is initiated by the addition of ATP. After incubation for 30 minutes at 25° C., 60 μl of Progressive IMAP Reagent (Molecular Devices) is added to stop the reaction. Change in RP7030's FP is determined by a FP reader (Analyst HT, LH, BioSystems).

Assay: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.

Target: Androgen receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P10275
Assay: Transactivation Assay: For determining the androgen receptor-dependent transcription, a cellular assay system was used, consisting of PC-3 cells (Kaighn et al., Invest. Urol. 17: 16-23, 1979), which express the human androgen receptor stably and recombinantly (full length, wild-type form, see Swiss-Prot Acc. No. P10275, Entry Version 159, Sequence Version 2). In addition, these PC3 cells contain a stably integrated reporter gene plasmid, which is based on the commercially available plasmid pGL4.14 (#E6691, Promega Corporation, Madison, Wis., USA) and contains the luciferase gene from the American firefly (Photinus pyralis) under the control of the MMTV promoter (Cato et al., EMBO J. 6: 363-368, 1987). These cells were propagated in routine cell culture at 37° C. and 5% CO2 in a medium containing 90% RPMI 1640 (Invitrogen GmbH, Darmstadt, Germany), 100 U penicillin, 100 μg/ml streptomycin (Invitrogen), 4 mM L-glutamine (Invitrogen), 10% fetal calf serum (FCS Serum Gold, PAA Laboratories GmbH, Cölbe, Germany), 600 μg/ml Geneticin (G418-sulphate, Invitrogen) and 10 μg/ml puromycin (Sigma Aldrich GmbH, Germany). For carrying out the transactivation assays, approx. 1000 cells per well were plated out in a 384-well cell culture plate in a medium that contained activated charcoal-treated calf serum (FCS Serum Gold, PAA Laboratories) at a concentration of 5% (v/v). The test substances were added in a concentration series from 5.12×10^−12 to 1×10^−5 M in the presence of 1×10^−1° R1881 (methyltrienolone). The test plates were incubated overnight at 37° C. and 5% CO2. After 16 hours, 15 μl of Steady Glo Lysis and Detection reagent (E2550, Promega Corporation, Madison, Wis., USA) was added per well and the luminescence was read in a Topcount Luminometer (PerkinElmer, Waltham, Mass., USA) for 4 seconds per well. The luminescence values obtained were normalized, wherein 100% corresponded to the effect of the unstimulated control (without R1881), and 0% corresponded to the effect of the stimulated control (R1881 plus DMSO instead of test substance).

N., Prot. Exp. & Purif. 2004, 33, 256). In addition to being easy to obtain in excellent yield and solubility, guinea pig liver TGase was chosen because it shows 80% homology with human tissue TGase (Aeschlimann, D.; Paulsson, M., Throm. Haemost. 1994, 71, 402) and may thus serve as a model for the evaluation of inhibitors of potential therapeutic utility.The IC50 values of synthetic analogues 14a-38a were determined from inhibition of the reaction of 54.4 mM of the chromogenic TGase substrate N-Cbz-Glu(Î³-p-nitrophenyl ester)Gly with 0.010 U of recombinant guinea pig liver TGase as previously reported (Leblanc, A.; Gravel, C.; Labelle, J.; Keillor, J.

Assay: Cellular Assay: Assay a) HT29 cells (ECACC #85061109) were seeded into 384 well assay plates (Costar #3712) at a density of 3500 cells/well in 40 μl EMEM medium containing 1% L glutamine and 10% FBS and allowed to adhere overnight. The following morning compounds of Formula (I) in 100% DMSO were added to assay plates by acoustic dispensing. After 1 h incubation at 37° C. and 5% CO2 plates (up to 6 at a time) were irradiated using the X-RAD 320 instrument (PXi) with equivalent to Ë¿600 cGy. Plates were returned to the incubator for a further 1 h. Then cells were fixed by adding 20 μl of 3.7% formaldehyde in PBS solution and incubating for 20 minutes at r.t. before being washed with 50 μl/well PBS, using a Biotek EL405 plate washer. Then 20 μ 0.1% Triton X100 in PBS was added and incubated for 20 minutes at r.t., to permeabalise cells. Then the plates were washed once with 50 μl/well PBS, using a Biotek EL405 plate washer. Phospho-ATM Ser1981 antibody (Millipore #MAB3806) was diluted 10000 fold in PBS containing 0.05% polysorbate/Tween and 3% BSA and 20 μl was added to each well and incubated over night at r.t. The next morning plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and then 20 μl of secondary Ab solution, containing 500 fold diluted Alexa Fluor® 488 Goat anti-rabbit IgG (Life Technologies, A11001) and 0.002 mg/ml Hoeschst dye (Life technologies #H-3570), in PBS containing 0.05% polysorbate/Tween and 3% BSA, was added. After 1 h incubation at r.t., the plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and plates were sealed and kept in PBS at 4° C. until read. Plates were read using an ArrayScan VTI instrument, using an XF53 filter with 10× objective. A two laser set up was used to analyse nuclear staining with Hoeschst (405 nm) and secondary antibody staining of pSer1981 (488 nm).
