Assay: Enzymatic Assay: The inhibitor potency of the exemplified compounds was measured in an enzyme assay that measures peptide phosphorylation using FRET measurements to detect product formation. Inhibitors were serially diluted in DMSO and a volume of 0.5 μL was transferred to the wells of a 384-well plate. For FGFR3, a 10 μL volume of FGFR3 enzyme (Millipore) diluted in assay buffer (50 mM HEPES, 10 mM MgCl2, 1 mM EGTA, 0.01% Tween-20, 5 mM DTT, pH 7.5) was added to the plate and pre-incubated for a time between 5-10 minutes and up to 4 hours. Appropriate controls (enzyme blank and enzyme with no inhibitor) were included on the plate. The assay was initiated by the addition of a 10 μL solution containing biotinylated EQEDEPEGDYFEWLE peptide substrate (SEQ ID NO: 1) and ATP (final concentrations of 500 nM and 140 μM respectively) in assay buffer to the wells. The plate was incubated at 25° C. for 1 hr. The reactions were ended with the addition of 10 μL/well of quench solution (50 mM Tris, 150 mM NaCl, 0.5 mg/mL BSA, pH 7.8; 30 mM EDTA with Perkin Elmer Lance Reagents at 3.75 nM Eu-antibody PY20 and 180 nM APC-Streptavidin). The plate was allowed to equilibrate for ˜1 hr before scanning the wells on a PheraStar plate reader (BMG Labtech).FGFR1, FGFR2, and FGFR4 are measured under equivalent conditions with the following changes in enzyme and ATP concentrations: FGFR1, 0.02 nM and 210 uM respectively, FGFR2, 0.01 nM and 100 uM, respectively, and FGFR4, 0.04 nM and 600 uM respectively. The enzymes were purchased from Millipore or Invitrogen.

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 assay was performed in white 96-well, flat-bottom, half-area, non-binding assay plate (Corning #3642) in assay buffer consisting of 20 mM HEPES (pH 7.5), 10 mM MgCl2*6H2O, 100 μM sodium orthovanadate, 0.05% CHAPS and 0.1% bovine serum albumin. A 10 μL aliquot of compound from each well of the intermediate dilution plate and 20 μL of a 2× substrate/enzyme solution containing acceptor substrate (800 nM RSK2 peptide KRRRLSSLRA (SEQ ID NO: 1)), ROCK2 enzyme (10 nM), or ROCK1 enzyme, and 1,4-Dithiothreitol (DTT, 2 μM) were added to all wells. The reaction was initiated by the addition of 10 μL of 4× stock solution ATP (2 ∥M). Reactions were thoroughly mixed manually, covered and allowed to incubate at room temperature for 75 min. Protein kinase activity was quantitated using Promega's KINASE-GLO luminescent Kinase Assay Kit according to the manufacturer's directions. ATP concentrations remaining in Test wells following the termination of the enzymatic reaction were compared against control wells containing equivalent amounts of DMSO containing no inhibitor (CTRL). ATP concentrations in both Test wells and CTRL wells were normalized against background (BKG) ATP concentrations in wells containing concentrations of inhibitor that completely inhibited the protein kinase under investigation (i.e. a concentration that prevented any consumption of ATP over the course of the incubation). Percent of Control (POC) values were determined for each concentration of compound tested according to the equation: POC=((Test well value−BKG)/(CTRL−BKG))*100IC50 values were calculated using the following 4-parameter logistic curve-fitting algorithm: f(x)=(A+((B−A)/(1+((x/C){circumflex over ( )}D))))IC50 values were converted to Ki values using the Cheng-Prusoff Equation: Ki=IC50/(1+([ATP]/Km ATP])).

Assay: Nav1.5 Assay: To assess the potential cardiac liability of compounds at an early stage in the drug discovery process, a Nav1.5 sodium channel screening assay was be performed on Molecular Device's PatchXpress™ automated electrophysiology platform. Under voltage-clamp conditions, Nav1.5 currents were recorded from HEK cells expressing the human Nav1.5 channel in the absence and presence of increasing concentrations of the test compound to obtain an IC50 value. The external recording solution contained (in mM): 90 TEACl, 50 NaCl, 1.8 CaCl, 1 MgCl2, 10 HEPES, 10 glucose, adjusted to pH 7.4 with TEA-OH and to 300 mOsm with sucrose (if necessary), while the internal patch pipette solution contained (in mM): 129 CsF, 2 MgCl2, 11 EGTA, 10 HEPES, 3 Na2ATP adjusted to pH 7.2 with CsOH and to 290 mOsm with sucrose (if necessary). Nav1.5 channel currents were evoked using a cardiac action potential waveform at 1 Hz, digitized at 31.25 kHz and low-pass filtered at 12 kHz.

Assay: Btk Enzyme Activity: Btk enzyme (His-Btk (Millipore catalog #14-552), is diluted to 0.4 U/mL in KR buffer (10 mM Tris-HCl, 10 mM MgCl2, 0.01% Tween-20, 0.05% NaN3, 1 mM DTT, 2 mM MnCl2, pH 7.2).Serial dilution log 10 from 2 mM to 63.2 nM of test compounds are made in 100% DMSO. The dilutions in DMSO are then diluted 50-fold in KR-buffer. Final compound concentration range in the assay from 10 μM to 0.316 nM.5 μL/well of test compound in KR buffer (final DMSO concentration in the assay is 1%) is mixed with 5 μl/well of 0.4 U/mL Btk enzyme (final concentration in the assay is 0.1 U/mL). Test compounds and Btk enzyme are pre-incubated 60 minutes at room temperature, before adding 5 μL/well of 200 nM Fluorescin labeled substrate peptide (Blk/Lyntide substrate, e.g. #R7188/#R7233, Molecular Devices) in KR-buffer. Final peptide substrate concentration in assay is 50 nM. The kinase assay is started by adding 5 μL/well of 20 μM ATP in KR-buffer (final ATP concentration is 5 μM ATP, Km ATP in Btk IMAP assay). Following incubation for 2 h at room temperature the enzyme reaction is stopped by adding 40 μL/well IMAP Progressive Binding Solution (according to suppliers (Molecular Devices) protocol using 75% 1× buffer A and 25% 1× buffer B with 1:600 Progressive Binding Solution). After 60 min incubation at room temperature in the dark the FP signal is read. Fluorescence at 535 nm is measured using parallel and perpendicular filters to determine differences in rotation due to binding of the phosphorylated substrate peptide to the beads. Values are calculated as percentage of the difference in readout (ΔmPi) of the controls with and without ATP. EC50 values are determined by curve fitting of the experimental results using Activity Base.

After a 60-minute incubation at 22° C., the reaction is measured using a PerkinElmer EnVision multimode plate reader via TR-FRET dual wavelength detection, and the percent of control (POC) calculated using a ratiometric emission factor. 100 POC is determined using no test compounds and 0 POC is determined using a concentration of control compound that completely inhibits the enzyme

Target: Hepatocyte growth factor receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P08581
Assay: Enzyme Assay: The affinity of compound binding to wild type and mutant human MET kinases is measured using Invitrogen's LanthaScreen Eu Kinase Binding technology. Briefly, GST-tagged recombinant human MET kinase domain from Signal Chem (see Table 8 below for concentration in assay) is incubated with 50 nM Alexa-Fluor® Tracer 236 (Invitrogen Cat No. PR9078A) and 2 nM Europium-anti-GST (Invitrogen Cat. No. A151 6) along with test compound in a buffer consisting of 25 mM HEPES, pH 7.4, 10 mM MgCl2, 0.01% Triton X-100, 1 mM DTT, and 2% DMSO.
