Target: Lysophosphatidic acid receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q92633
Assay: Receptor Assay: Engagement of the LPA1 receptor by its ligand, oleoyl-L-Î±-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C. The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA1 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro.Â  Approximately 10,000 cells in normal culture medium (Dulbecco's Modified Eagle Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom collagen coated 384 well plate (Beckton Dickinson). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1x Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1x Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake.

Assay: Electrophysiology Assay: After establishing the whole-cell configuration in voltage clamp mode, voltage protocols were run to establish the 1) test potential, 2) holding potential, and 3) the conditioning potential for each cell. After establishing the whole-cell configuration in voltage clamp mode, a standard I-V protocol was run to determine the potential at which the maximal current (Imax) is elicited. This potential was the test potential (Vt). To determine a conditioning potential at which 100% of channels were in the inactivated state, a standard steady-state inactivation (SSIN) protocol was run using a series of fifteen 100 ms-long depolarizing prepulses, incrementing in 10 mV steps, immediately followed by a 5 ms testing pulse, Vt, to Vmax. This protocol also permitted determination of the holding potential at which all channels are in the resting state.

Assay: Kinase Homogeneous Time-Resolved Fluorescence Assay: The N-terminally His6-tagged recombinant kinase domain of the human c-Met (amino acids 960-1390), expressed in insect cells (SF21) and purified by Ni-NTA affinity chromatography and consecutive size exclusion chromatography (Superdex 200), is used. Alternatively, commercially available c-Met (Millipore) can be used. As substrate for the kinase reaction, the biotinylated poly-Glu, Tyr (4:1) copolymer (#61GTOBLC, Cis Biointernational, Marcoule, France) is used. For the assay, 50 mL of a 100-fold concentrated solution of the test compound in DMSO is pipetted into a black low-volume 384-well microtiter plate (Greiner Bio-One, Frickenhausen, Germany). 2 μL of a solution of c-Met in assay buffer [25 mM Hepes/NaOH, pH 7.5; 5 mM MgCl2; 5 mM MnCl2; 2 mM dithiothreitol; 0.1% (v/v) Tween 20 (Sigma); 0.1% (w/v) bovine serum albumin] are added, and the mixture is incubated for 15 min at 22° C. to allow pre-binding of the test compound to the enzyme before the start of the kinase reaction. Then, the kinase reaction is started by the addition of 3 μL of a solution of adenosine triphosphate (ATP, 16.7 μM; final concentration in the 5 μL assay volume is 10 μM) and substrate (2.27 μg/mL, final concentration in the 5 μL assay volume is 1.36 μg/mL Ë¿30 nM) in assay buffer, and the resulting mixture is incubated for a reaction time of 30 min at 22° C. The concentration of c-Met in the assay is adjusted depending on the activity of the enzyme lot and is appropriately chosen to have the assay in the linear range; typical enzyme concentrations are in the range of about 0.03 nM (final concentration in the 5 μL assay volume). The reaction is stopped by the addition of 5 μL of a solution of HTRF detection reagents [40 nM streptavidine-X Lent and 2.4 nM PT66-Eu-chelate, an europium-chelate labelled anti-phosphotyrosine antibody (Perkin-Elmer)] in an aqueous EDTA solution [100 mM EDTA, 0.2% (w/v) bovine serum albumin in 50 mM HEPES/NaOH, pH 7.5]. The resulting mixture is incubated for 1 h at 22° C. to allow the binding of the biotinylated phosphorylated peptide to the streptavidine-XLent and the PT66-Eu-chelate. Subsequently, the amount of phosphorylated substrate is evaluated by measurement of the resonance energy transfer from the PT66-Eu-chelate to the streptavidine-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm are measured in an HTRF reader, e.g. Rubystar (BMG Lab-technologies, Offenburg, Germany) or Viewlux (Perkin-Elmer). The ratio of the emissions at 665 nm and at 622 nm is taken as the measure for the amount of phosphorylated substrate.

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
