Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
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: Trans-Phosphorylation Assay: The inhibitory activity of putative kinase inhibitors and the potency of selected compounds were determined using a trans-phosphorylation assay.Specific peptide or protein substrates were trans-phosphorylated by their specific ser-thr or tyr kinase in the presence of ATP traced with 33P-gamma-ATP, and in the presence of their own optimal buffer and cofactors. At the end of the phosphorylation reaction, more than 98% unlabeled ATP and radioactive ATP were captured by an excess of the ion exchange dowex resin; the resin then settled down to the bottom of the reaction plate by gravity. Supernatant was subsequently withdrawn and transferred into a counting plate, then evaluated by beta-counting.

Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
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.).

Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
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.

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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
