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.

UniProt: P49840
Assay: GSK 3α Enzyme Inhibition Assay: The inhibitory activities of compounds of the invention against the GSK 3α enzyme isoform (Invitrogen), are evaluated by determining the level of activation/phosphorylation of the target peptide. The GSK3-α protein (500 ng/mL, 2.5 uL) is mixed with the test compound (2.5 uL at either 4 ug/mL, 0.4 ug/mL, 0.04 ug/mL, or 0.004 ug/mL) for 2 hr at RT. The FRET peptide (8 uM, 2.5 uL), which is a phosphorylation target for GSK3α, and ATP (40 uM, 2.5 uL) are then added to the enzyme/compound mixture and the resulting mixture incubated for 1 hr. Development reagent (protease, 5 uL) is added for 1 hr prior to detection in a fluorescence microplate reader (Varioskan Flash, ThermoFisher Scientific).

UniProt: P35968
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.).

Pfluegers Archives 391:85-100 (1981)) using the IonWorks Quattro automated electrophysiology platform (Molecular Devices, Sunnyvale, Calif.). Chinese hamster ovary cells stably expressing Kir1.1 channels were maintained in T-75 flasks in cell culture media in a humidified 10% CO2 incubator at 37° C. Prior to an experiment, Kir1.1 expression was induced by overnight incubation with 1 mM sodium butyrate.

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 μL 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: KiNativ assay: Sample preparation: A375 cells from ATCC are lysed by sonication in commercially available lysis buffer, cleared by centrifugation, and the resulting supernatant gel filtered into a commercially available kinase reaction buffer containing 20 mM MnCl2. Final protein concentration of lysates are 10 mg/mL. 5 ul of each test compound is added from 100 uM, 10 uM, 1 uM, or 0.1 uM stock solutions in DMSO to 500 uL of lysate in duplicate for final concentrations of 1 uM, 0.1 uM, 0.01 uM, and 0.001 uM. 5 ul, of DMSO is added to 500 ul of lysate in quadruplicate for controls. After 15 minute incubation, desthiobiotin-ATP acylphosphate probe is added to each sample to a final concentration of 5 uM and incubated with the samples for 10 minutes. Following the probe reaction, samples are prepared for targeted mass spectrum analysis using ActivX standard protocol.

Target: Cannabinoid receptor 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P34972
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).
