Cell plates were incubated for 18 h in a 37° C. incubator before dosing with compounds of formula (I) in 100% DMSO using acoustic dispensing. Compounds were dosed in a 12 point concentration range into a randomised plate map. Control wells were generated either by dosing of 100% DMSO (max signal) or addition of a reference compound (a PI3K-β inhibitor) that completely eliminated the pAKT signal (min control). Plates were incubated, at 37° C. for 2 h, cells were then fixed by the addition of 10 μl of a 3.7% formaldehyde solution. After 30 minutes the plates were washed with PBS using a Tecan PW384 plate washer. Wells were blocked and cells permeabilised with the addition of 40 μl of PBS containing 0.5% Tween20 and 1% Marvel™ (dried milk powder) and incubated for 60 minutes at r.t. The plates were washed with PBS containing 0.5% (v/v) Tween20 and 20 μl rabbit anti-phospho AKT Ser473 (Cell Signalling Technologies, #3787) in same PBS-Tween+1% Marvel™ was added and incubated overnight at 4° C. Plates were washed 3 times with PBS 0.05% Tween 20 using a Tecan PW384. 20 μl of secondary antibody Alexa Fluor 488 anti-Rabbit (Molecular Probes, #A11008) diluted in PBS+0.05% Tween20 containing 1% Marvel™ was added to each well and incubated for 1 h at r.t. Plates were washed three times as before then 20 μl PBS added to each well and plates sealed with a black plate sealer. The plates were read on an Acumen plate reader as soon as possible, measuring green fluorescence after excitation with 488 nm laser.

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease. See Caterina Trozzi et al., In Vitro Selection and Characterization of Hepatitis C Virus Serine Protease Variants Resistant to an Active-Site Peptide Inhibitor, 77(6) J. Virol. 3669 (2003).

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.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
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.

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).

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.)

Target: Tyrosine-protein kinase JAK2 (SINGLE PROTEIN), Homo sapiens
UniProt: O60674
Assay: In vitro JAK Kinase Assay: 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.)

Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
Assay: In Vitro Inhibition Assay: ITK and JAK3 Kinase assay procedures:Enzyme was incubated with substrate peptide in reaction buffer in the presence and absence of test compounds or Staurosporine. All additions were done on ice, followed by the addition of ATP mix. Wells were uniformly mixed using an Eppendorff plate shaker and incubated at 30° C. for 20 min, and stopped by the addition of 5 μL of 3% phosphoric acid. Volume was increased to 100 μL by adding 0.8% phosphoric acid which was then transferred to PC filter mats (Millipore), pre-equilibrated with 70% ethanol and water. Plates were washed thrice with 100 μL 0.8% phosphoric acid and dried for an hour at 60° C. 100 μL scintillation fluid was added into each well and reading taken in Perkin Elmer TOPCOUNT beta counter. The data analysis was performed by averaging the duplicate top count readings for each standard, negative, positive control (enzyme control) and samples and subtracting the average negative control from each reading which results in corrected values.

Assay: Cell Viability Assay and IC50 Estimation: Cell viability was determined using the Cell Titer Glo assay (Promega) as previously described. Briefly, 2000-3000 cells per well were plated in 384-well plates (Greiner Bio-One) in technical triplicate. Cells were treated with seven different concentrations of tyrosine kinase inhibitors or vehicle alone at a final volume of 40 μL per well. After 3 days hours, 11 μL of Cell Titer Glo was added to each well. Plates were shaken for 15 minutes, and bioluminescence was determined using a FLUOstar OPTIMA multi-mode micro-plate reader (BMG LABTECH). Bioluminescence values were normalized to DMSO treated cells, and normalized values were plotted in GraphPad Prism using non-linear regression fit to normalized data with a variable slope. IC50 values were calculated by GraphPad Prism at 50% inhibition.
