Assay: Biochemical Assay: The autoparsylation activity of the TNKS 1/2 or PARP1/2 enzymes was measured by the liquid chromatography-mass spectrometry (LC/MS) detection of nicotinamide as readout. Compound activity in inhibiting the TNKS and PARP autoparsylation was evaluated by IC50 measurements. In the compound screening assays, the reaction is composed of 5 uL of compound in 8-point serial dilutions with concentrations ranging from 0.0086 to 18.75 uM, 20 nM of purified enzyme, and 250 uM of p-NAD+ in the 1x Assay Buffer. After 60 min incubation at room temperature, the reactions were quenched by the addition of 10 uL of 5x quenching solution (20% formic acid and 500 nM [d]-nicotinamide in water). For the background control wells, 10 uL of the 5x quenching solution per well was added prior to the addition of p-NAD+. The % Inhibition was calculated as: (Control-Sample)/(Control-Background)*100. "Control" is the average value of 8 wells without compound; and "Background" is the average of 8 wells mixed with 5x quenching solution measured prior to initiation of the reaction.

Assay: Radioligand Binding Assay: Binding assays were performed as described in [J. A. O'Brien et al. Mol Pharmacol., 2003, 64, 731-740] with slight modifications, including that a radioligand that binds to the methyl-5-(2-pyridinylethynyl)pyridine (MPEP) binding site was used in place of [3H]-MPEP. Briefly, after thawing, the membrane homogenates were resuspended in 50 mM Tris-HCl and 0.9% NaCl binding buffer at pH 7.4 to a final assay concentration of 20 g protein/well for radioligand filtration binding. Incubations included 5 nM radioligand, membranes and either buffer or varying concentrations of compound. Samples were incubated for 60 min at room temperature with shaking. Non-specific binding was defined with 10 μM cold MPEP when using the radioligand. After incubation, samples were filtered over a GF/C filter (presoaked in 0.25% polyethyleneimine (PEI)) and then washed 4 times using a Tomtec® Harvester 96® Mach III cell harvester (Tomtec, Hamden, Conn.) with 0.5 mL ice-cold 50 mM Tris-HCl (pH 7.4). IC50 values were derived from the inhibition curve and Ki values were calculated according to the Cheng and Prusoff equation of Ki=IC50/(1+[L]/Kd) described in [Y. Cheng and W. H. Prusoff Biochem. Pharmacol. 1973, 22, 3099-3108] where [L] is the concentration of radioligand and Kd is its dissociation constant at the receptor, derived from the saturation isotherm.

Target: Tyrosine-protein kinase JAK2 (SINGLE PROTEIN), Homo sapiens
UniProt: O60674
Assay: Biochemical HTRF Assay: The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at ambient temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at ambient temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction. Plates were shaken and centrifuged and then incubated 60 minutes at ambient temperature and then read on a Perkin Elmer Envision (λex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading.

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.

Target: Mu-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35372
Assay: GTPgammaS Functional Assay (U-2): [35S]GTPgammaS functional assays were conducted using freshly thawed pt-receptor membranes prepared in-house from a cell line expressing recombinant mu opioid receptor in a U-2 OS cell background, or purchased from a commercial source (Perkin Elmer, Shelton, Conn.; or DiscovRx, Fremont, Calif.). Assay reactions were prepared by sequentially adding the following reagents to binding buffer (100 mM NaCl, 10 mM MgCl2,20 mM HEPES, pH 7.4) on ice (final concentrations indicated): membrane protein (0.026 mg/mL), saponin (10 mg/mL), GDP (3 mM) and [35S]GTPgammaS (0.20 nM; Perkin Elmer, Shelton, Conn.). The prepared membrane solution (190 ul/well) was transferred to 96-shallow well polypropylene plates containing 10 ul of 20x concentrated stock solutions of the agonist [D-Ala2, N-methyl-Phe4 Gly-ol5]-enkephalin (DAMGO) prepared in dimethyl sulfoxide (DMSO). Plates were incubated for 30 min at about 25° C. with shaking. Reactions were terminated by rapid filtration onto 96-well Unifilter GF/B.
