UniProt: O60674
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.).

UniProt: Q9P1W9
Assay: Enzyme Assay: 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 uM. A reference compound was included on each assay plate in order to validate that plate; on

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.

Assay: ThermoFluor® Assay: Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1 °C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1×=46 nL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

Assay: Sandwich ELISA Assay: For measuring the autophosphorylation of the endogenous Tie2 receptor in the cell lysates prepared, a self-prepared anti-Tie2 antibody directed against the N-terminus of the Tie-2 receptor (1.09 mg/ml) and an HRP-coupled anti-phosphotyrosine antibody (Sigma, A4595, clone pY-20) were used. White 96-well ELISA plates (Lumitrac600, Greiner, #655074) were incubated with 100 μl per well of a 1:1000 dilution of the anti-Tie2 antibody in coating buffer [15 mM Na2CO3, 35 mM NaHCO3, pH 9.6] with shaking at 4° C. overnight. The coated ELISA plates were washed three times with 250 μl PBST buffer [0.1% Tween-20 in PBS], the wells were blocked with 250 μl 3% BSA in PBST buffer with shaking at RT for 1-6 h and washed three more times with 250 μl PBST buffer. From the cell lysate plates thawed in the fridge, in each case 100 μl of lysate were transferred into the coated wells of the ELISA plates, and the plates were incubated with shaking at 4° C. overnight. The plates were washed three times with in each case 250 μl of PBST buffer, and 100 μl of a 1:5000 dilution of the anti-phosphotyrosine HRP antibody in 3% Prionex (Calbiochem, #529600) in PBST were then pipetted into each well and the plates were incubated with shaking and protected from light at 4° C. overnight. The plates were washed three times with in each case 250 μl of PBST, and 100 μl of chemiluminescent substrate [BM Chemiluminescence ELISA Substrate (POD) Reagent A and B 1:100, Roche, #1582950] were then pipetted into each well, and after 3 min the plates were measured using a luminescence reader.

Target: Rho-associated protein kinase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O75116
Assay: In Vitro Assay: The effectiveness of compounds of the present invention as ROCK inhibitors can be determined in a 30 μL assay containing 20 mM HEPES, pH 7.5, 20 mM MgCl2, 0.015% Brij-35, 4 mM DTT, 5 μM ATP and 1.5 μM peptide substrate (FITC-AHA-AKRRRLSSLRA-OH). Compounds were dissolved in DMSO so that the final concentration of DMSO was <2%, and the reaction was initiated with Rho kinase variants. After incubation, the reaction was terminated by the addition of EDTA and the phosphorylated and non-phosphorylated peptides separated using a LABCHIP® 3000 Reader (Caliper Life Sciences). Controls consisted of assays that did not contain compound, and backgrounds consisted of assays that contained enzyme and substrate but had EDTA from the beginning of the reaction to inhibit kinase activity.

Assay: FAAH Assay: T84 frozen cell pellets or transfected SK-N-MC cells (contents of 1x15 cm culture dishes) were homogenized in 50 mL of FAAH assay buffer (125 mM Tris, 1 mM EDTA, 0.2% Glycerol, 0.02% Triton X-100, 0.4 mM Hepes, pH 9). The assay mixture consisted of 50 uL of the cell homogenate, 10 uL of the test compound, and 40 pt of anandamide [1-3H-ethanolamine] (3H-AEA, Perkin-Elmer, 10.3 Ci/mmol), which was added last, for a final tracer concentration of 80 nM. The reaction mixture was incubated at rt for 1 h. During the incubation, 96-well Multiscreen filter plates (catalog number MAFCNOB50; Millipore, Bedford, Mass., USA) were loaded with 25 uL of activated charcoal (Multiscreen column loader, catalog number MACL09625, Millipore) and washed once with 100 uL of MeOH. Also during the incubation, 96-well DYNEX MicroLite plates (catalog number NL510410) were loaded with 100 uL of MicroScint40 (catalog number 6013641, Packard Bioscience, Meriden, Conn., USA).
