Assay: Radioligand Binding Assay: HEK-293 cells stably expressing rat TAAR1 were maintained at 37° C. and 5% CO2 in DMEM high glucose medium, containing fetal calf serum (10%, heat inactivated for 30 min at 56° C.), penicillin/streptomycin (1%), and 375 ug/ml geneticin (Gibco). Cells were released from culture flasks using trypsin/EDTA, harvested, washed twice with ice-cold PBS (without Ca2+ and Mg2+), pelleted at 1,000 rpm for 5 min at 4° C., frozen and stored at -80° C. Frozen pellets were suspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 10 mM EDTA and homogenized with a Polytron (PT 6000, Kinematica) at 14,000 rpm for 20 s. The homogenate was centrifuged at 48,000Ã¿g for 30 min at 4° C. Subsequently, the supernatant was removed and discarded, and the pellet resuspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 0.1 mM EDTA using the Polytron (20 s at 14,000 rpm). This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at -80° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 uM unlabeled ligand. All compounds were tested at a broad range of concentrations (10 pM to 10 uM) in duplicates. The test compounds (20 ul/well) were transferred into a 96 deep well plate (TreffLab), and 180 ul of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 ul of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3xKd in nM and 500 ul of the membranes (resuspended at 50 ug protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer. After addition of 45 ul of Microscint 40 (PerkinElmer) the Unifilter-96 plate was sealed and after 1 hr the ratioactivity counted using a TopCount Microplate Scintillation Counter (Packard Instrument Company).

Assay: Sandwich ELISA Assay: For measuring the autophosphorylation of the endogenous Tie2 receptor in the cell lysates prepared, a self-prepared anti-Tie2 antibody directed against the N-terminus of the Tie-2 receptor (1.09 mg/ml) and an HRP-coupled anti-phosphotyrosine antibody (Sigma, A4595, clone pY-20) were used. White 96-well ELISA plates (Lumitrac600, Greiner, #655074) were incubated with 100 μl per well of a 1:1000 dilution of the anti-Tie2 antibody in coating buffer [15 mM Na2CO3, 35 mM NaHCO3, pH 9.6] with shaking at 4° C. overnight. The coated ELISA plates were washed three times with 250 μl PBST buffer [0.1% Tween-20 in PBS], the wells were blocked with 250 μl 3% BSA in PBST buffer with shaking at RT for 1-6 h and washed three more times with 250 μl PBST buffer. From the cell lysate plates thawed in the fridge, in each case 100 μl of lysate were transferred into the coated wells of the ELISA plates, and the plates were incubated with shaking at 4° C. overnight. The plates were washed three times with in each case 250 μl of PBST buffer, and 100 μl of a 1:5000 dilution of the anti-phosphotyrosine HRP antibody in 3% Prionex (Calbiochem, #529600) in PBST were then pipetted into each well and the plates were incubated with shaking and protected from light at 4° C. overnight. The plates were washed three times with in each case 250 μl of PBST, and 100 μl of chemiluminescent substrate [BM Chemiluminescence ELISA Substrate (POD) Reagent A and B 1:100, Roche, #1582950] were then pipetted into each well, and after 3 min the plates were measured using a luminescence reader.

Assay: FL5.12 Cellular Assay: The efficacy of the compounds of Formula (I) can also be determined in cell-based killing assays using a variety of cell lines and mouse tumor models. For example, their activity on cell viability can be assessed on a panel of cultured tumorigenic and non-tumorigenic cell lines, as well as primary mouse or human cell populations. In one exemplary set of conditions, mouse FL5.12 cells transfected with Bcl-XL were cultured under standard conditions in RPMI with 2 mM glutamine, 1% 100 mM sodium pyruvate, 2% 1 M HEPES, 4 uL/L of beta;-mercaptoethanol, 1% penicillin-streptomycin, 10% FBS, and 10% WEHI-3B conditioned media (for IL-3). For assaying the compound activity, the cells were exchanged into an IL-3-depleted deprivation media, which was identical to the growth media except for the absence of FBS and WEHI-3B conditional media, for 2 days. Then the cells were exchanged to 3% FBS assay media (RPMI with 2 mM glutamine, 1% 100 mM sodium pyruvate, 2% 1 M HEPES, 4 uL/L of beta;-mercaptoethanol, 1% penicillin-streptomycin, 10% FBS, and 10% WEHI-3B conditioned media (for IL-3).

Assay: Enzyme Inhibition Assay: Measurements were performed using a modification of the scintillation proximity assay platform described previously by Georgopapadakou, N. H. et al. (22nd International Congress on Chemotherapy, 2001, Abstract P16.001). Compounds were solubilised in DMSO at a top concentration of 10 mM and serially diluted in half log steps to achieve a range of final assay concentrations of 100 uM to 1 nM. Compound at each concentration (100-fold final) was added to white 384 well plates in a volume of 0.5 ml. Human, A. fumigatus, T. brucei or L. major N-myristoyl transferase enzyme, dissolved to a working concentration of 10 nM in assay buffer (30 mM Tris/HCl pH 7.4, 0.5 mM EGTA, 0.5 mM EDTA, 1.25 mM DTT, 0.1% Triton X-100), was then added to columns 1 to 11 and 13 to 23 of the plates in a volume of 20 ml. To columns 12 and 24, 20 ml assay buffer was added to provide a no enzyme control. Following a 5 minute incubation at room temperature the substrates (GCGGSKVKPQPPQAK(Biotin)-Amide and myristoyl coenzyme A), dissolved in assay buffer, were added to all wells in a volume of 20 ml to start the reaction. The final concentrations of peptide and 3H-myristoyl coenzyme A were 0.5 mM and 125 nM respectively and the specific activity of the radiolabel was 8 Ci/mmol. Plates were then incubated at room temperature for up to 50 minutes (dependant upon the period of linearity for the different enzyme species) before SPA beads, suspended to 1 mg/ml in a stop solution (200 mM Phosphoric Acid/NaOH pH 4, 750 mM MgCl2), were added in a volume of 40 ml.

UniProt: O60885
Assay: Bromodomain Domain Binding Assay: A time-resolved fluorescence resonance energy transfer (TR-FRET) assay was used to determine the affinities of compounds of the Examples listed in Table 1 for each bromodomain of human BRD4. His-tagged first (BD1: amino acids K57-E168) and second (BD2: amino acids E352-E168) bromodomains of human BRD4 were expressed and purified. An Alexa647-labeled BET-inhibitor was used as the fluorescent probe in the assay. Compound dilution series were prepared in DMSO via a 3-fold serial dilution from 2.5 mM to 42 nM. Compounds were then diluted 6:100 in assay buffer (20 mM Sodium Phosphate, pH 6.0, 50 mM NaCl, 1 mM Ethylenediaminetetraacetic acid disodium salt dihydrate, 0.01% Triton X-100, 1 mM DL-Dithiothreitol) to yield 3× working solutions. Six microliters (L) of the working solution was then transferred to white, low-volume assay plates (Costar #3673). A 1.5× assay mixture containing His-tagged bromodomain, Europium-conjugated anti-His antibody (Invitrogen PV5596) and the Alexa-647-conjugated probe molecule was also prepared. Twelve L of this solution were added to the assay plate to reach a final volume of 18 L. The final concentration of 1× assay buffer contains 2% DMSO, 50 M-0.85 nM compound, 8 nM His-tagged bromodomain, 1 nM Europium-conjugated anti-His-tag antibody and 100 nM or 30 nM probe (for BDI or BDII, respectively). After a one-hour incubation at room temperature, TR-FRET ratios were determined using an Envision multilabel plate reader (Ex 340, Em 495/520).

Assay: Inhibition Assay: V79 MZh11B1 and V79 MZh 11B2 cells (8˙10^5 cells per well) were grown to confluency on 24-well cell culture plates with 1.9 cm^2 culture area per well (Nunc, Roskilde, Denmark). Before the test, the DMEM culture medium present was removed, and 450 μl of fresh DMEM with inhibitor was added for at least three concentrations to each well to determine the IC50. After preincubation (60 min, 37 °C.), the reaction was started by adding 50 μl of DMEM with 2.5 μl of solution of the substrate 11-deoxycorticosterone (20 μM, containing 1.25 nCi of [4-14C]11-deoxycorticosterone in ethanol). Thereafter, the plate was stored at 37 °C. and 5% CO2 in a CO2 incubator. The V79 MZh 11B1 cells were incubated for 120 min, and the V79 MZh 11B2 cells were incubated for 40 min. Controls without inhibitor were treated in the same way. The enzyme reactions were quenched by extracting the supernatant with 500 μl of EtOAc. The samples were centrifuged (10,000 g, 2 min), the solvent was removed and evaporated. The residue was taken up in 10 μl of chloroform and analyzed by HPTLC (see below).

UniProt: P98170
Assay: TR-FRET Assay: The peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA ("Peptide A") was identified as a substrate for the TR-FRET assay by screening the 6× Histidine-tagged BIR2 domain and BIR3 domain of XIAP against a set of 29 peptides synthesized based on sequences reported by Sweeny et al. (Biochemistry, 2006, 45, 14740 14748). The peptides were labeled with the fluorescent tags FITC or TAMRA and Kd values were determined by fluorescence polarization assay. The sequence AVPIAQKSEK was identified as optimal for using in an assay. The peptide sequence was derivatized with biotin to provide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA as the substrate for the TR-FRET assay. Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-C1, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 mM incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The final buffer conditions were as follows: 60 mM Hepes, pH 7.0, 0.05% BSA, 2 mM DTT. Incubations were carried out at RT (22° C.) for 2 h for Pim-1, 1 hour and 30 min for Pim-3, and 45 min for Pim-2. The reaction was stopped by the addition of 3 mM EDTA, and fluorescence was measured by an HTRF® Rubystar microplate reader.

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.times.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.degree. C. for 30 min Compounds were added to a final assay volume of 100 ul 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 ul lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN.sub.3) and 50 ul detection solutions (20 uM mAb Alexa700-cAMP 1:1, and 48 uM 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.

Assay: In Vitro Inhibition Assay: KLK1 inhibitory activity in vitro was determined using standard published methods (see e.g. Johansen et al., Int. J. Tiss. Reac. 1986, 8, 185; Shori et al., Biochem. Pharmacol., 1992, 43, 1209; Stürzebecher et al., Biol. Chem. Hoppe-Seyler, 1992, 373, 1025). Human KLK1 (Callbiochem) was incubated at 37° C. with the fluorogenic substrate H-DVal-Leu-Arg-AFC and various concentrations of the test compound. Residual enzyme activity (initial rate of reaction) was determined by measuring the change in optical absorbance at 410 nm and the IC50 value for the test compound was determined.
