Target: Bromodomain-containing protein 4 (SINGLE PROTEIN), Homo sapiens
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).

Target: cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y233
Assay: In Vitro Assay: Human recombinant PDE10A2 was expressed in Sf9 cells, using a recombinant baculovirus construct containing the full length sequence containing a 6Ã¿His sequence following the start Met to allow metal affinity purification of the recombinant protein. Cells were harvested and the phosphodiesterase protein was purified by metal chelate chromatography on Ni-sepharose 6FF.The affinity of the compounds of Formula (I) for phophodiesterases (PDE) was measured by a scintillation proximity assay (SPA). PDE Yttrium Silicate SPA beads allow PDE activity to be measured by direct binding of the primary phosphate groups of non-cyclic AMP or GMP to the beads via a complex iron chelation mechanism. The amount of bound tritiated product ([3H]-AMP) is measured by liquid scintillation counting.The compounds were dissolved and diluted in 100% DMSO in polystyrene plates to a concentration of 100-fold the final concentration in the assay. Human PDE10A enzyme solution (10 uL) was added.

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 384-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 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer].

Assay: MGAT LCMS Assay: The MGAT enzyme reactions were performed in CORNING Falcon 96-well Polypropylene plates, in a total volume of 60 uL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 uM 2-oleoylglycerol, 15 uM oleoyl-Coenzyme A and 0.0013 ug/uL Human or Mouse MGAT-2 or 0.0026 ug/uL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 uL of ice cold methanol containing 1 ug/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50x2.1 mm column, was used for the chromatography of enzyme products.

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×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 °C. for 30 min. Compounds were added to a final assay volume of 100 μl 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 μl lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN3) and 50 μl detection solutions (20 μM mAb Alexa700-cAMP 1:1, and 48 μM 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 as follows: FRET=T730-Alexa730-P(T645-B645) with P=Ru730-B730/Ru645-B645, where T730 is the test well measured at 730 nM, T645 is the test well measured at 645 nm, B730 and B645 are the buffer controls at 730 nm and 645 nm, respectively. cAMP content is determined from the function of a standard curve spanning from 10 μM to 0.13 nM cAMP.
