Compound (SMILES): CN(C[C@@H](Nc1ncnc2c1=CCCC=2C(N)=O)c1ccccc1)C1CC1
InChIKey: MUFCACSRTIFNRI-GOSISDBHSA-N
Target: 3-phosphoinositide-dependent protein kinase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: O15530
Assay: Enzyme Assay: The kinase assay is performed as 384-well Flashplate assay (PerkinElmer LAS Germany GmbH). 3.4 nM His6-PDK1(Delta 1-50) (PDK1 that has a His-tag consisting of six histidines and lacks the first fifty amino acids), 400 nM PDKtide (Biotin-bA-bAKTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC as the substrate, and 4 μM ATP (spiked with 0.25 μCi 33P-ATP/well) are incubated in a total volume of 50 μl (50 mM TRIS, 10 mM Mg-acetate, 0.1% Mercaptoethanol, 0.02 Brij35, 0.1% BSA, pH 7.5) with or without test compound (5-10 concentrations) for 60 Min at 30° C. The reaction is stopped with 25 μl 200 mM EDTA. After 30 Min at room temperature the liquid is removed and each well washed thrice with 100 ml 0.9% sodium chloride solution. Nonspecific reaction is determined in presence of 100 nM of the high affinity protein kinase inhibitor Staurosporine. Radioactivity is measured in a Topcount (PerkinElmer LAS Germany GmbH).

Target: Ribosomal protein S6 kinase beta-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23443
Assay: Enzyme Assay: P70S6K inhibitor compounds are diluted and plated in 96 well plates. A reaction mixture including the following components is then added to the compound plate to initiate the enzyme reaction; P70S6K (3 nM, T412E mutant, Millipore) is mixed with 24 μM ATP in an assay buffer containing 100 mM Hepes (pH 7.5), 5 mM MgCl2, 1 mM DTT, 0.015% Brij and 1 μM of the substrate peptide FITC-AHA-AKRRRLSSLRA-OH (derived from the S6 ribosomal protein sequence, FITC=fluorescein isothiocyanate, AHA=6-aminohexanoic acid). The reaction is incubated for 90 min at 25° C., before the addition of 10 mM EDTA to stop the reaction. The proportion of substrate and product (phosphorylated) peptide is analysed on a Caliper Life Sciences Lab Chip 3000, using a pressure of −1.4 psi, and upstream and downstream voltages of −3000 and −700 respectively.

Target: Aurora kinase A (SINGLE PROTEIN), Homo sapiens
UniProt: O14965
Assay: Enzyme Assay: The Aurora assays described here are performed on two Caliper Life Sciences systems: the LC3000 and the Desktop Profiler. These provide data on enzyme activity via measurement of the relative amounts of phosphorylated or unphosphorylated fluorescently labelled substrate peptide at the end of an enzymatic reaction. These different states of peptide are resolved by applying a potential difference across the sample. The presence of the charged phosphate group on the product (as opposed to the substrate) causes a different peptide mobility between the two peptides. This is visualized by excitation of the fluorescent label on the substrate and product peptides and represented as peaks within the analysis software.

Target: Aurora kinase B (SINGLE PROTEIN), Homo sapiens
UniProt: Q96GD4
Assay: Enzyme Assay: The Aurora assays described here are performed on two Caliper Life Sciences systems: the LC3000 and the Desktop Profiler. These provide data on enzyme activity via measurement of the relative amounts of phosphorylated or unphosphorylated fluorescently labelled substrate peptide at the end of an enzymatic reaction. These different states of peptide are resolved by applying a potential difference across the sample. The presence of the charged phosphate group on the product (as opposed to the substrate) causes a different peptide mobility between the two peptides. This is visualized by excitation of the fluorescent label on the substrate and product peptides and represented as peaks within the analysis software.

Assay: Kinase Inhibition Assay: The following assay protocol is for measuring the phosphorylation of a peptide substrate (FAM-KKLRRTLSVA-OH wherein FAM is carboxyfluorescein). The peptide is >98% purity by Capillary Electrophoresis. The peptide is phosphorylated by the protein kinase ROCK1 or ROCK2. The ROCK1 or ROCK2 enzyme, substrate, and cofactors (ATP and Mg2+) are combined in a well of a microtiter plate and incubated for 3 hours at 25° C. in the presence or absence of an inhibitor compound. At the end of the incubation, the reaction is quenched by the addition of an EDTA-containing buffer. The substrate and product are separated and quantified electrophoretically using the microfluidic-based LABCHIP® 3000 Drug Discovery System from Caliper Life Sciences (Hopkinton, Mass.).The components of the assay mixture are:100 mM HEPES, pH 7.50.1% BSA0.01% Triton X-1001 mM DTT10 mM MgCl210 μM Sodium Orthovanadate10 LM Beta-Glycerophosphate5 μM ATP (for ROCK1) or 7 μM ATP (for ROCK2)1% DMSO (from compound)1.25 μM FAM-KKLRRTLSVA-OH3 nM ROCK1 or 2.5 nM ROCK2 enzymeSubstrate and product peptides present in each sample are separated electrophoretically using the LABCHIP® 3000 capillary electrophoresis instrument. As substrate and product peptides are separated two peaks of fluorescence are observed. Change in the relative fluorescence intensity of the substrate and product peaks is the parameter measured reflecting enzyme activity. Capillary electrophoregramms (RDA acquisition files) are analyzed using HTS Well Analyzer software (Caliper Life Sciences, Hopkinton, Mass.). The kinase activity in each sample is determined as the product to sum ratio (PSR): P/(S+P), where P is the peak height of the product peptide and S is the peak height of the substrate peptide. For each compound, enzyme activity is measured at various concentrations (12 concentrations of compound spaced by 3× dilution intervals).

Assay: PI3K Enzyme Assay A2: Materials: Lipid kinase substrate, phosphoinositol-4,5-bisphosphate (PIP2), was purchased from Echelon Biosciences (Salt Lake City, Utah). PI3K isoforms α, β, δ and γ were purchased from Millipore (Bedford, Mass.). ATP, MgCh, DTT, EDTA, MOPS and CHAPS were purchased from Sigma-Aldrich (St. Louis, Mo.).The kinase reaction was conducted in clear-bottom 96-well plate from Thermo Fisher Scientific in a final volume of 24 μL. Inhibitors were first diluted serially in DMSO and added to the plate wells before the addition of other reaction components. The final concentration of DMSO in the assay was 0.5%. The PI3K assays were carried out at room temperature in 20 mM MOPS, pH 6.7, 10 mM MgCl2, 5 mM DTT and CHAPS 0.03%. The reaction mixture was prepared containing 50 μM PIP2, kinase and varying concentration of inhibitors. Reactions were initiated by the addition of ATP containing 2.2 μCi [γ-33P]ATP to a final concentration of 1000 μM. The final concentration of PI3K isoforms α, β, δ and γ in the assay were 1.3, 9.4, 2.9 and 10.8 nM respectively. Reactions were incubated for 180 min and terminated by the addition of 100 μL of 1 M potassium phosphate pH 8.0, 30 mM EDTA quench buffer. A 100 μL aliquot of the reaction solution was then transferred to 96-well Millipore MultiScreen IP 0.45 μm PVDF filter plate (The filter plate was prewetted with 200 μL 100% ethanol, distilled water, and 1 M potassium phosphate pH 8.0, respectively). The filter plate was aspirated on a Millipore Manifold under vacuum and washed with 18×200 μL wash buffer containing 1 M potassium phosphate pH 8.0 and 1 mM ATP. After drying by aspiration and blotting, the plate was air dried in an incubator at 37° C. overnight. Packard TopCount adapter (Millipore) was then attached to the plate followed with addition of 120 μL Microscint 20 scintillation cocktail (Perkin Elmer) in each well. After the plate sealing, the radioactivity of the product was determined by scintillation counting on Topcount (Perkin-Elmer). IC50 determination was performed by fitting the curve of percent control activity versus the log of the inhibitor concentration using the GraphPad Prism 3.0 software. Compounds having and IC50 value of 10 μM or less are considered active.

Target: 3-phosphoinositide-dependent protein kinase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: O15530
Assay: Enzyme Assay: The kinase assay is performed as 384-well Flashplate assay (PerkinElmer LAS Germany GmbH). 3.4 nM His6-PDK1(Delta 1-50) (PDK1 that has a His-tag consisting of six histidines and lacks the first fifty amino acids), 400 nM PDKtide (Biotin-bA-bAKTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC as the substrate, and 4 μM ATP (spiked with 0.25 μCi 33P-ATP/well) are incubated in a total volume of 50 μl (50 mM TRIS, 10 mM Mg-acetate, 0.1% Mercaptoethanol, 0.02 Brij35, 0.1% BSA, pH 7.5) with or without test compound (5-10 concentrations) for 60 Min at 30° C. The reaction is stopped with 25 μl 200 mM EDTA. After 30 Min at room temperature the liquid is removed and each well washed thrice with 100 ml 0.9% sodium chloride solution. Nonspecific reaction is determined in presence of 100 nM of the high affinity protein kinase inhibitor Staurosporine. Radioactivity is measured in a Topcount (PerkinElmer LAS Germany GmbH).
