Target: cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y233
Assay: Fluorescence Polarization Assay: The fluorescence polarization assay for cyclic nucleotide phosphodiesterases was performed using an IMAPÂ® FP kit supplied by Molecular Devices, Sunnyvale, Calif. (product #R8139). IMAPÂ® technology has been applied previously to phosphodiesterase assays (Huang, W., et al., J. Biomol Screen, 2002, 7: 215). Assays were performed at room temperature in 384-well microtiter plates with an incubation volume of 20.2 ul. Solutions of test compounds were prepared in DMSO and serially diluted with DMSO to yield 8 uL of each of 10 solutions differing by 3-fold in concentration, at 32 serial dilutions per plate. 100% inhibition is determined using a known PDE10 inhibitor, which can be any compound that is present at 5,000 times its Ki value in the assay described as follows, such as papaverine (see Siuciak, et al. Neuropharmacology (2006) 51:386-396; Becker, et al. Behav Brain Res (2008) 186(2):155-60; Threlfell, et al., J Pharmacol Exp Ther (2009) 328(3):785-795), 2-{4-[pyridin-4-yl-1-(2,2,2-trifluoroethyl)-1H-pyrazol-3-yl]phenoxymethyl}quinoline succinic acid or 2-[4-(1-methyl-4-pyridin-4-yl-1H-pyrazol-3-yl)-phenoxymethyl]quinoline succinic acid (see Schmidt, et al. J Pharmacol Exp Ther (2008) 325:681-690; Threlfell, et al., J Pharmacol Exp Ther (2009) 328(3): 785-795). 0% of inhibition is determined by using DMSO (1% final concentrations). A Labcyte Echo 555 (Labcyte, Sunnyvale, Calif.) is used to dispense 200 nL from each well of the titration plate to the 384 well assay plate. A solution of enzyme (1/1600 dilution from aliquots; sufficient to produce 20% substrate conversion) and a separate solution of FAM-labeled cAMP PDE from Molecular Devices (product #R7506), at a final concentration of 50 nM are made in the assay buffer (10 mM Tris HCl, pH 7.2, 10 mM MgCl2, 0.05% NaN3 0.01% Tween-20, and 1 mM DTT). The enzyme and the substrate are then added to the assay plates in two consecutive additions of 10 uL, and then shaken to mix. The reaction is allowed to proceed at room temperature for 30 minutes. A binding solution is then made from the kit components, comprised of 80% Solution A, 20% Solution B and binding reagent at a volume of 1/600 the total binding solution. The enzymatic reaction is stopped by addition of 60 uL of the binding solution to each well of the assay plates and the plates are sealed and shaken for 10 seconds. The plate was incubated at room temperature for at least one hour prior to determining the fluorescence polarization (FP). The parallel and perpendicular fluorescence of each well of the plate was measured using a Perkin Elmer Enyision plate reader (Waltham, Mass.).

Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

Assay: In Vitro Inhibition of Ca Flux Assay: The 5HT3 antagonist activity of the compounds of the invention was determined by measuring the ability of the compounds to inhibit the calcium flux activity of 3HT3a receptor expressed in HEK-293T cells. HEK-293T cells were transfected with the 5HT3a expression construct using Xtreme Gene 9 (Roche) in 150 mm tissue culture treated plates and incubated for 24 hours at 37 °C. Cells were then split and plated at a density of 60K cells/well in poly-lysine coated, black 96-well plates with clear bottoms (BD BioSciences) and incubated overnight at 37 °C. Growth media was removed and cells loaded with 200 uL calcium indicator dye in HBSS containing 20 mM HEPES (Calcium 5 Assay kit, Molecular Devices) and incubated at 37 °C. for 1 hour. While cells were incubating, the 10× antagonist and agonist/antagonist addition plates were made. For 10× antagonist plate: half log serial dilutions (final concentrations range from 10−7 through 10−10 with the bottom well a negative, no ligand control) were made from test compounds in DMSO at a 1000× concentration and then diluted to 10× in HBSS/20 mM HEPES. For addition plate: 5HT was diluted to 100× in HBSS/20 mM HEPES (final concentration in the assay−216 nM) and 15 uL was added to each well of the addition plate, 15 uL of 10× compound was also added to the addition plate, and finally 120 uL of HBSS/20 mM HEPES (for a total of 150 uL). Cells were then removed from the incubator and equilibrated to room temperature for 10 minutes, then 22.5 uL of 10× test compounds were added in triplicate to the plates and incubated at room temperature for 10 minutes (Tropisetron was used as a positive control in every assay).

Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).

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.

UniProt: P11309
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 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 μM. A reference compound was included on each assay plate in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The final buffer conditions were as follows: 60 mM Hepes, pH 7.0, 0.05% BSA, 2 mM DTT. Incubations were carried out at RT (22° C.) for 2 h for Pim-1, 1 hour and 30 min for Pim-3, and 45 min for Pim-2. The reaction was stopped by the addition of 3 mM EDTA, and fluorescence was measured by an HTRF® Rubystar microplate reader.

Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.
