Assay: Cellular Assay: Assay c) BT474 cells (human breast ductal carcinoma, ATCC HTB-20) were seeded into black 384 well plates (Costar, #3712) at a density of 5600 cells/well in DMEM containing 10% FBS and 1% glutamine and allowed to adhere overnight. The following morning compounds in 100% DMSO were added to assay plates by acoustic dispensing. After a 2 h incubation at 37° C. and 5% CO2, the medium was aspirated and the cells were lysed with a buffer containing 25 mM Tris, 3 mM EDTA, 3 mM EGTA, 50 mM sodium fluoride, 2 mM Sodium orthovanadate, 0.27 M sucrose, 10 mM β-glycerophosphate, 5 mM sodium pyrophosphate, 0.5% Triton X-100 and complete protease inhibitor cocktail tablets (Roche #04 693 116 001, used 1 tab per 50 ml lysis buffer). After 20 minutes, the cell lysates were transferred into ELISA plates (Greiner #781077) which had been pre-coated with an anti total-AKT antibody in PBS buffer and non-specific binding was blocked with 1% BSA in PBS containing 0.05% Tween 20. Plates were incubated over night at 4° C. The next day the plates were washed with PBS buffer containing 0.05% Tween 20 and further incubated with a mouse monoclonal anti-phospho AKT T308 for 2 h. Plates were washed again as above before addition of a horse anti-mouse-HRP conjugated secondary antibody. Following a 2 h incubation at r.t., plates were washed and QuantaBlu substrate working solution (Thermo Scientific #15169, prepared according to provider's instructions) was added to each well. The developed fluorescent product was stopped after 60 minutes by addition of Stop solution to the wells. Plates were read using a Tecan Satire plate reader using 325 nm excitation and 420 nm emission wavelengths respectively. Except where specified, reagents contained in the Path Scan Phospho AKT (Thr308) sandwich ELISA kit from Cell Signalling (#7144) were used in this ELISA assay.

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
Assay: Enzyme Assay: 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 uM. A reference compound was included on each assay plate in order to validate that plate; on

The plate was incubated for 60 minutes at room temperature. The Raf kinase activity reaction was started by the addition of 5 mL per well of 2×ATP diluted in assay buffer. After 3 hours (b-Raf(V600E)) or 1 hour (c-Raf). The reactions were stopped and the phosphorylated product was measured using a rabbit anti-p-MEK (Cell Signaling, #9121) antibody and the Alpha Screen IgG (ProteinA) detection Kit (PerkinElmer #6760617R), by the addition of 10 mL to the well of a mixture of the antibody (1:2000 dilution) and detection beads (1:2000 dilution of both beads) in Stop/bead buffer (25 mM EDTA, 50 mM Tris, pH 7.5, 0.01% Tween20). The additions were carried out under dark conditions to protect the detection beads from light. A lid was placed on top of the plate and incubated for 1 hour at room temperature, then the luminescence was read on a PerkinElmer Envision instrument. The concentration of each compound for 50% inhibition (IC50) was calculated by non-linear regression using XL Fit data analysis software.

Assay: Binding Assay: The affinity to the human μ-opiate receptor was determined in a homogeneous preparation in microtiter plates. For this, dilution series of the respective compound to be tested were incubated for 90 minutes at room temperature with a receptor membrane preparation (15-40 mg of protein per 250 μl of incubation batch) of CHO-K 1 cells, which express the human μ-opiate receptor (RB-HOM receptor membrane preparation of NEN, Zaventem, Belgium), in the presence of 1 nmol/l of the radioactive ligand [3H'-naloxone (NET719, NEN, Zaventem, Belgium) and of 1 mg WGA-SPA beads (wheat germ agglutinin SPA beads from Amersham/Pharmacia, Freiburg, Germany) in a total volume of 250 μl. 50 mmol/l of tris-HCl supplemented by 0.05% by wt. of sodium azide and 0.06% by wt. of bovine serum albumin was used as incubation buffer. 25 μmol/l of naloxone were additionally added to determine the non-specific bond. After the ninety-minute incubation time had ended, the microtiter plates were centrifuged for 20 minutes at 1000 g and the radioactivity measured in a β-counter (Microbeta-Trilux, PerkinElmer Wallac, Freiburg, Germany).

UniProt: P17948
Assay: FLIPR (Fluorometric Imaging Plate Reader) Technology Assay: Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of PDGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. NHDF-Ad (Normal human dermal fibroblasts) (Lonza) were seeded in 384-well fibronectin coated black-walled plates overnight at 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 4 times (ELx405-CW, Bio-Tek) to remove extracellular dye. Test compounds were reconstituted in 100% DMSO and added to the cells to give a final DMSO concentration of 0.1%. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 μM) or at concentrations ranging from 0.001 nM to 10 μM followed by PDGF stimulation (10 ng/mL). Changes in fluorescence at 515 nm were measured simultaneously in all 384 wells using a cooled CCD camera.
