Assay: Enzyme Assay: JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl2, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS.

Assay: Human ACC1 Enzyme Assay: For the assay, 50 nl of a 100-times concentrated solution of the test substance in DMSO were pipetted into a white low-volume 384-well microtitre plate (Greiner Bio-One, Frickenhausen, Germany), 2.5 μl of a solution of hACC1 in assay buffer [50 mM HEPES/NaOH pH 7.5, 2 mM MgCl2, 2 mM potassium citrate, 12 mM NaHCO3, 2 mM dithiothreitol (DTT), 0.005% (w/v) bovine serum albumin (BSA)] were added and the mixture was incubated for 15 min to allow prebinding of the substances to the enzyme prior to the enzyme reaction. The enzyme reaction was then started by addition of 2.5 μl of a solution of adenosine triphosphate (ATP, 100 μM=>final concentration in 5 μl of assay volume: 50 μM) and acetyl-CoA (20 μM=>final concentration in 5 μl assay volume: 10 μM) in assay buffer, and the resulting mixture was incubated at 22 °C. for the reaction time of 45 min. The concentration of the hACC1 was adjusted to the respective activity of the enzyme and set such that the assay was carried out in the linear range. Typical concentrations were in the range of 1.75 μl. The reaction was stopped by addition of 2.5 μl of the "ADP-GLO reagent" (1:1.5-times diluted), and the resulting mixture was incubated at 22 °C. for 1 h to convert the unreacted ATP completely into cAMP. 2.5 μl of the "kinase detection reagent" were then added (1.2-times more concentrated than recommended by the manufacturer), the resulting mixture was incubated at 22 °C. for 1 h and the luminescence was then measured using a suitable measuring instrument (Viewlux or Topcount from Perkin-Elmer or Pherastar from BMG Labtechnologies).

UniProt: P15538
Assay: G402-Based Assay: Herein we identified the use of the G-402 cell line as a host cell to ectopically express (transiently or stably) enzymes of the CYP11 family. Specifically we developed stable G-402 cells expressing ectopically human CYP11B1, human CYP11B2, human CYP11A1, cynmolgus CYP11B1 or cynomolgus CYP11B2 enzyme activity. Importantly the identified cell line G-402 expresses co-factors (adrenodoxin and adrenodoxin reductase) important for the activity of the CYP11 family and no relevant enzyme activity of the CYP11 family (in comparison to H295R cells) was detected in these cells. Therefore the G-402 cell line is uniquely suited as a host cell for the ectopic expression of enzymes from the CYP11 family.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.

Assay: Inhibition Assay: To initiate an assay, replicon cells were plated in the presence of a dilution series of test compound in the absence of G418. Typically, the assays were performed in a 96-well plate formate for manual operation, or a 384-well plate format for automated assay. Replicon cells and compound were incubated for 96 hours. At the end of the assay, cells were washed free of media and compound, and the cells were then lysed. RNA was quantified indirectly through detection of replicon-encoded NS3/4A protein levels, through an ELISA-based assay with an antibody specific for NS3/4A.

Assay: Luciferase Assay: The Huh-7 cells transfected with HCV replicons system were seeded into 96-well plates (8,000 cells in 125 μL/well) respectively; each test compound was diluted to desired concentration using 5-fold serial dilutions protocol, 10 doses in duplicate, and added to wells with POD™ 810 Plate Assembler. The plates were incubated in a CO2 incubator for 72 hours; after that, 40 μL of Luciferase assay substrate (Promega Bright-Glo) was added to each well, and detected by a chemiluminescence detection system (Topcount Microplate Scintillation and Luminescence Counter) 5 minutes later; the EC50 (half-maximal effective concentration, concentration for 50% of maximal effect) values of test compounds were analyzed by GraphPad Prism software, respectively. In this paper, experiments were repeated twice and set the holes without compounds as negative control.

UniProt: Q9Y233
Assay: In Vitro Assay hPDE10a: Human recombinant PDE10A2 was expressed in Sf9 cells, using a recombinant baculovirus construct containing the full length sequence containing a 6×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 to 20 μL, of incub
