Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
Assay: In Vitro Kinase Assay: In vitro kinase assays described below can be used to determine the activity of a test compound for inhibiting the activity of JAK3 kinase. The test compounds were dissolved in dimethyl sulfoxide and diluted with water to a serial concentration gradient as required by the experiment. JAK3 substrates (Cell Signaling Technology, Catalog Number: 1305s) and ATP (2 mM) solution were diluted with water to obtain a final concentration of 20 M ATP and 1.2 M substrate solution. The appropriate amount of JAK3 kinase (Invitrogen, Catalog Number: pv3 855) was mixed with 4x buffer (prepared by user, and comprising 50 mM HEPES, pH 7.3, 125 mM NaCl, 24 mM MgCl2, 1.25 mM DTT) to a final concentration of 8 ng/uL. To each well of a microplate [DELFIA Streptavidin-coated clear plate (Perkin Elmer, Item: AAAND-0005)]17.5 uL of ATP/substrate mixture, 5 uL of aqueous solution of a test compound (L of pure water only were added to the control and blank), and 7.5 uL of the kinase solution prepared above (4x buffer only was added to the control) were added. Each well was mixed sufficiently, then incubated at room temperature (27° C.) for 50 minutes, washed with wash buffer, and dried three times, then HRP conjugated antibody [Phospho-Tyrosine Mouse mAb (P-Tyr-100) (HRP Conjugate, Cell signaling Technology, Catalog Number: 5465)] was added, and incubated for 1 hour. The microplate was washed with wash buffer and dried three times, and then TMB (Sigma, Catalog Number: T4444) was added and incubated for 5 to 15 minutes to allow for color change. Stop solution (1 N sulfuric acid solution) was added to stop the reaction. Absorbance was measured on a Novostar microplate reader at a wavelength of 450 nm. IC50 values of test compounds were calculated from the data of the test compounds for inhibiting the activity of JAK3 kinase at different concentrations.

Assay: MYLK/MLCK Assay: MYLK dissociation constants (Kd) for compounds were determined using the DiscoverX KdELECT platform. The MYLK kinase (accession number NP_444254.3) was labeled with a DNA tag for subsequent qPCR readout while a known active site binding ligand (staurosporine) was immobilized on a solid support (beads). Test compounds were prepared as 111X stocks in 100% DMSO and Kds were determined using an 11-point 3-fold compound dilution series with three DMSO control points. The compounds were then diluted directly into the assays such that the final concentration of DMSO was 0.9%. The assay plates were incubated at room temperature with shaking for 1 hour to equilibrate. The affinity beads were washed (lx PBS, 0.05% Tween 20) to remove unbound kinase and quantify MYLK captured on solid support by qPCR. The Kd was determined by measuring the amount of MYLK captured on the solid support as a function of the test compound concentration. The Kd values were calculated by fitting dose-response curves to the Hill binding equation using the Levenberg-Marquardt algorithm.

Assay: Caliper Assay: A kinase selectivity panel which measures substrate peptide phosphorylation was set-up for wild-type ALK2 (aa172-499), ALK2 FOP mutant (aa172-499 R206H), ALK1 (aa166-493), ALK5 (aa162-503) and ALK6 (aa168-495). The technology used for the described assay is based on the separation and quantification of substrate and product in an electrical field. In the course of the kinase reaction the peptide substrate is phosphorylated by a kinase. The transfer of a phosphate residue also causes the introduction of two additional negative charges and hence to a change in the net charge of the phospho-peptide compared to the unphosphorylated peptide. Due to this difference in charge the phosphorylated und unphosphorylated peptides migrate with different velocities in an electrical field.In the applied method, this separation takes place inside a chip that contains a complex capillary system for simultaneous analysis of 12 samples (12-sipper chip, Caliper Technologies Corp., Mountain View, USA).

Assay: ROCK Kinase Inhibition Assays: All compounds were initially prepared as 10 mM stocks in anhydrous dimethylsulfoxide (DMSO). A 20 μl aliquot of the 10 mM solutions was transferred to individual wells in column 1 of a 96-well polypropylene microtiter plate (Corning #3363) and diluted with DMSO to give a final compound concentration of 4 mM. Test compounds were then serially diluted 1:5 in DMSO for an 11-point concentration response and further diluted in the assay buffer bringing all compound concentrations to a final range of 100 μM to 10 pM in 2.5% DMSO.

The plate was blocked with 200 μL/well of Block Buffer (1% BSA; 5% sucrose; 0.5 mM MnCl2; in 1×TBS) at 37° C. for 2 h. Dilutions of testing compounds and recombinant TGFβ1 LAP (0.67 μg/mL) in binding buffer (0.05% BSA; 2.5% sucrose; 0.5 mM MnCl2; in 1×TBS) were added. The plate was incubated for 2 hours at 25° C., washed, and incubated for 1 hour with Biotin-Anti-hLAP. Bound antibody was detected by peroxidase-conjugated streptavidin. The IC50 values for testing compounds were calculated by four-parameter logistic regression.
Measurement: IC50 = 150 nM (pChEMBL 6.820000171661377)
