Target: Cytochrome P450 2D6 (SINGLE PROTEIN), Homo sapiens
UniProt: P10635
Assay: Cytochrome P450 Inhibition: Protocol 1: Studies were carried out in human liver microsomes. Human liver microsomes were purchased from BD Gentest. DMSO stocks were prepared for the test compounds. Aliquots of the DMSO solutions were diluted 1:3 by acetonitrile:ACN mixture (v/v: 40:60) to "400×" intermediate solutions, then further diluted by liver microsomes/buffer to "2×" intermediate solutions. "2×" intermediate solutions were mixed with "2×" NADPH/substrate solutions, which had been pre-warmed to 37° C. (final test compound concentrations were 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, 0.0136 μM, and 0 μM). The plates were kept in a 37° C. water bath for the duration of the experiment. At the end of incubation (5 minutes for 3A4; 45 minutes for 2C19; 10 minutes for 1A2, 2C9, 2D6), 120 μL of acetonitrile was added into corresponding wells. After the final time point was sampled, the plates were shaken at a vibrator (IKA, MTS 2/4) for 10 mM (600 rpm/min) and then centrifuged at 5594 g for 15 mM (Thermo Multifuge×3R). Aliquots of the supernatant were removed, diluted 1:1 into distilled water, and analyzed by LC-MS/MS. The peak area response ratio to internal standard (PARR) of the compounds at 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, and 0.0136 μM was compared to the PARR at 0 μM to determine the percent of metabolite generation from substrate at each test compound concentration.

Assay: DAO Inhibition Assay: Recombinant human DAO (2.4 μg/mL) was used as source of DAO enzyme activities. The assay was performed as described in the method for human SSAO/VAP-1 (Example 5) except the substrate used was 200 μM putrescine, and the control wells contained 10 μM aminoguanidine instead of Mofegiline: Briefly, in a standard 96 well plate assay 50 μL of purified human SSAO/VAP-1 (0.25 μg/mL) in 0.1 M NaPO4 buffer (pH 7.4) was added into each well. Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 4-9 data points, typically in the micromolar or nanomolar range after incubation with human SSAO/VAP-1 for 30 min at 37 °C. After 30 min incubation, 50 μL of the reaction mixture containing 600 μM benzylamine (Sigma Aldrich), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 0.1 M NaPO4 buffer (pH 7.4) were added to the corresponding well. The fluorescence unit (RFU) was read every 2.5 min for 30 min at 37 °C. excitation 565 nm and emission 590 (Optima; BMG labtech). The slope of the kinetics for each well was calculated using MARS data analysis software (BMG labtech) and this value was used to deduce the IC50 value (Dotmatics).

Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

Assay: Cellular Enzyme Assay: G-402 cells expressing CYP11 constructs were established as described above and maintained in McCoy's 5a Medium Modified, ATCC Catalog No. 30-2007 containing 10% FCS and 400 ug/ml G418 (Geneticin) at 37° C. under an atmosphere of 5% CO2/95% air. Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 uM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

UniProt: O00329
Assay: PI3K-delta Selective Assay: A compound's ability in selectively inhibiting PI3K-δ can be assessed using RAJI cells, i.e., B lymphocyte cells derived from lymphoma patients. Briefly, serum-starved RAJI cells are stimulated with anti-human IgM, thereby causing signaling through the B-cell receptors, as described in, for example, He et al., Leukemia Research (2009) 33: 798-802. B-cell receptor signaling is important for the activation, differentiation, and survival of B cells and certain B-cell derived cancers. Reduction of phospho-AKT is indicative of compounds that may inhibit B-cell proliferation and function in certain diseases. By monitoring the reduction of phospho-AKT in stimulated RAJI cells (using for example, phospho-AKT antibodies), a compound's potential efficacy in selectively inhibiting PI3Kδ can be assessed.

Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

UniProt: P23458
Assay: In Vitro JAK Kinase Assay: Compounds herein were tested for inhibitory activity of JAK targets according to the following in vitro assay described in Park et al., Analytical Biochemistry 1999, 269, 94-104. The catalytic domains of human JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a. 781-1124) with an N-terminal His tag were expressed using baculovirus in insect cells and purified. The catalytic activity of JAK1, JAK2 or JAK3 was assayed by measuring the phosphorylation of a biotinylated peptide. The phosphorylated peptide was detected by homogenous time resolved fluorescence (HTRF). IC50s of compounds were measured for each kinase in the 40 microL reactions that contain the enzyme, ATP and 500 nM peptide in 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL (0.01%) BSA. For the 1 mM IC50 measurements, ATP concentration in the reactions was 1 mM. Reactions were carried out at room temperature for 1 hr and then stopped with 20 uL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20 in assay buffer (Perkin Elmer, Boston, Mass.). Binding to the Europium labeled antibody took place for 40 minutes and HTRF signal was measured on a Fusion plate reader (Perkin Elmer, Boston, Mass.).

Assay: HDAC Activity Assay: HDAC assay is performed using fluorescently-labeled acetylated substrate, which comprises an acetylated lysine side chain. After incubation with HDAC, deacetylation of the substrate sensitizes the substrate such that, in a second step, treatment with the detection enzyme produces a fluorophore. HDACs 1 and 6 were expressed as full length fusion proteins. Purified proteins were incubated with 50 μM fluorescently-labeled acetylated peptide substrate and test compound for 2 hours at RT in HDAC assay buffer containing 50 mM Tris-HCl (pH 8.0), 137 mM NaCl, 2.7 mM KCl, 1 mM MgCl2, 1% DMSO, and 1% BSA. Reactions were terminated by the addition of the Developer after 2 hours, and the development of fluorescence signal, which was relative to the amount of deacetylated peptide, was monitored by time-course measurement of EnVision (PerkinElmer). The HDAC activity was estimated from the slope of time-course measurement of the fluorescence intensity.
