UniProt: P41143
Assay: Scintillation Proximity Assay (SPA): Briefly, serial dilutions of the test compounds were placed in a 96-well plate to which were added SPA beads, membrane and radioligand. The assay conditions for each opioid receptor subtype are described in Table 10 below. The plates were incubated for 8 hours-overnight at room temperature, spun at 1000 rpm to pellet the SPA beads, and radioactivity was measured using the TopCount microplate Scintillation counter. Specific binding at each concentration of test compound was calculated by subtracting the non-specific binding measured in the presence of excess cold ligand. IC50 values were obtained by non-linear regression of specific binding versus concentration curves and Ki values were calculated using Kd values that were experimentally pre-determined for each lot of membrane preparations.

Assay: Functional Assay (GTPgammaS Binding): The EC50 and Imax for mu opioid receptors was determined using a [I35S]GTPgammaS binding assay. This assay measures the functional properties of a compound by quantifying the level of G-protein activation following agonist binding in studies using stably transfected cells, and is considered to be a measure of the efficacy of a compound. Membranes from CHO (Chinese Hamster Ovary) cells that stably expressed the cloned human Mu opioid receptor were used in the experiments. Specifically, in a final volume of 0.5 mL, 12 different concentrations of each test compound were incubated with 7.5 ug of CHO cell membranes that stably expressed the human mu opioid receptor. The assay buffer consisted of 50 mM Tris-HCl, pH 7.4, 3 mM MgCl2, 0.2 mM EGTA, 3 uM GDP, and 100 mM NaCl. The final concentration of [35S]GTPgammaS was 0.080 nM. Nonspecific binding was measured by inclusion of 10 uM GTPgammaS. Binding was initiated by the addition of the membranes.

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.

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

Assay: In Vitro Cell Proliferation Potency Assay: BaF3, a murine interleukin-3 dependent pro-B cell line, parental cells, BaF3 PIM1 cells, BaF3 PIM2 cells, and MM1.S (multiple myeloma) cells were seeded at 2 k/well, 5 k/well, 5 k/well, and 10 k/well respectively, in a 384-well plate, at 45 μL/well. Test compound was added at 5 μL/well. BaF3 cells (parental and transfected) were incubated overnight, while MM1.S cells were incubated for 72 hours at 37° C., 5% CO2. CELL TITER GLO® Reagent (Promega) was added at 50 μL/well, the plates were incubated for 30 minutes, and their luminescence read on an HT Analyst.

Target: Coagulation factor XI (SINGLE PROTEIN), Homo sapiens
UniProt: P03951
Assay: Inhibition Assay: Factor XIa determinations were made in 50 mM HEPES buffer at pH 7.4 containing 145 mM NaCl, 5 mM KCl, and 0.1% PEG 8000 (polyethylene glycol; JT Baker or Fisher Scientific). Determinations were made using purified human Factor XIa at a final concentration of 25-200 pM (Haematologic Technologies) and the synthetic substrate S-2366 (pyroGlu-Pro-Arg-pNA; CHROMOGENIX® or AnaSpec) at a concentration of 0.0002-0.001 M.

Target: Proprotein convertase subtilisin/kexin type 9 (SINGLE PROTEIN), Homo sapiens
UniProt: Q8NBP7
Assay: Cell Free Assay: In order to eliminate the permeability barrier inherent to the WT7 and SCHH cell-based assays a cell-free system was also established to access compound activity. A sequence containing the full length human PCSK9 (NCBI reference identifier, NM-174936.3, where coding sequence start annotated at position 363) along with 84 additional 3â¿² nucleotides, comprising a V5 tag and polylinkinker followed by an in frame modified firefly luciferase reporter (corresponding to nucleotide positions 283-1929 of pGL3, Gen Bank reference identifier JN542721.1) was cloned into the pT7CFE1 expression vector (ThermoScientific). The construct was then in-vitro transcribed using the MEGAscript T7 Kit (Life Technologies) and RNA subsequently purified incorporating the MEGAclear Kit (Life Technologies) according to manufacturer's protocols. HeLa cell lysates were prepared following the protocols described by Mikami (reference is Cell-Free Protein Synthesis Systems with Extracts from Cultured Human Cells, S. Mikami, T. Kobayashi and H. Imataka; from Methods in Molecular Biology, vol. 607, pages 43-52, Y. Endo et al. (eds.), Humana Press, 2010) with the following modifications.
