GSK3beta Mobility Shift Assay The purpose of GSK3β assay is to evaluate the inhibition (% inhibition, Kiapp and Ki values) of small molecule inhibitors by using a fluorescence-based microfluidic mobility shift assay. GSK3β catalyzes the production of ADP from ATP that accompanies the phosphoryl transfer to the substrate peptide FL-Peptide-15 (5-FAM-KRREILSRRPpSYR-COOH, CPC Scientific, Sunnyvale, Calif.) (SEQ ID NO:2). The mobility shift assay electrophoretically separates the fluorescently labeled peptides (substrate and phosphorylated product) following the kinase reaction. Both substrate and product are measured and the ratio of these values is used to generate % conversion of substrate to product by the LabChip EZ Reader. Active GSK3β (H350L) was purchased from Upstate/Millipore. Typical reaction solutions (50 μL final reaction volume) contained 2% DMSO (±inhibitor), 4 mM MgCl2, 1 mM DTT, 40 μM ATP (ATP Km=9.43 μM), 0.005% Tween-20, 2 μM FL-Peptide-15, and 0.6 nM GSK3β in 25 mM HEPES buffer at pH 7.5. The assay was initiated with the addition of ATP, following 15 minutes pre-incubation of enzyme and inhibitor at room temperature in the reaction mixture. The reaction was stopped after 30 minutes at room temperature by the addition of 50 μL of 80 mM EDTA. The Ki value was determined from the fit of the data to the Morrison tight-binding competitive inhibition equation with the enzyme concentration as a variable. See Morrison, J. F. (1969) Kinetics of the reversible inhibition of enzyme-catalysed reactions by tight-binding inhibitors, Biochimica et biophysica acta 185, 269-286; Murphy, D. J.

Inhibition Assay Protein Kinase C beta 2 (PKCβII) catalyzes the production of ADP from ATP that accompanies the phosphoryl transfer to the PKC Pseudosubstrate peptide (A→S, RFARKGSLRQKNV). This transfer is coupled to the oxidation of β-NADH through the activities of Pyruvate Kinase (PK) and Lactate Dehydrogenase (LDH). β-NADH conversion to NAD+ is monitored by the decrease in absorbance at 340 nm (e=6.22 cm−1 mM−1) using a Molecular Devices SPECTRA max PLUS spectrophotometer.A typical assay was carried out on a 96-well, clear microtiter plate in a Molecular Devices spectrophotometer for 20 minutes at 30° C. in 0.1 mL of assay buffer containing 50 mM HEPES, pH 7.4, 5 nM PKC, 23 units of pyruvate kinase, 33 units of lactate dehydrogenase, 0.15 mM peptide, 0.1 mM ATP, 1 mM DTT, 4 mM PEP, 8 mM MgCl2, 0.3 mM NADH, 60 mM CaCl2, 10 mg/mL PS, 50 ng/mL PMA, 7.5% DMSO and from about 10,000 nM to 0.169 nM compound inhibitor. Stock solutions of 3-sn-phosphatidyl-L-serine (PS) and phorbol-12-myristate-13-acetate (PMA) were sonicated for 30 seconds just prior to addition to assay buffer and assays were initiated by the addition of 100 μM ATP.Steady-state kinetic parameters for the bi-bi kinase reaction were determined at saturating phospho-acceptor peptide substrate concentration (0.15 mM) by fitting initial velocity data to the Michaelis-Menten equation, v=V max [S]/(K M +[S]) where v is the measured initial velocity, Vmax is the maximal enzyme velocity, [S] is the ATP substrate concentration, and KM is the Michealis constant for ATP. Enzyme turnover values (kcat) were calculated according to kcat=Vmax[E], where [E] is the total enzyme concentration. Enzyme inhibition constants (apparent Ki values) were determined by fitting initial velocities at variable inhibitor concentrations to a model for ATP competitive inhibition based on the Morrison equation).

Enzyme Assay AXL enzyme inhibition (% inhibition, Kiapp and Ki values) by small molecule inhibitors was evaluated using a fluorescence-based microfluidic mobility shift assay. AXL catalyzes the production of ADP from ATP that accompanies the phosphoryl transfer to the substrate peptide FL-Peptide-30 (5-FAM-KKKKEEIYFFF-CONH2, CPC Scientific, Sunnyvale, Calif.). The mobility shift assay electrophoretically separates the fluorescently labeled peptides (substrate and phosphorylated product) following the kinase reaction. Both substrate and product are measured and the ratio of these values is used to generate % conversion of substrate to product by the LabChip EZ Reader. Human wild-type receptor tyrosine kinase protein Axl comprising residues 505-811 was produced in-house using the baculoviral expression vector system that incorporated a hexahistidine affinity tag into the protein (LJIC-1916B1.1). The enzyme was preactivated by auto-phosphorylation of 34 uM non-activated enzyme in the presence of 2 mM ATP, 4 mM MgCl2, 50 mM NaCl and 1 mM TCEP in 20 mM HEPES, pH 7.3 at 4° C. for 30 minutes. Typical reaction solutions (50 μL final reaction volume) contained 2% DMSO (±inhibitor), 10 mM MgCl2, 1 mM DTT, 120 μM ATP (ATP Km=70.4 μM), 0.01% Tween-20, 3 μM FL-Peptide-30, and 0.5 nM phosphorylated AXL enzyme in 100 mM HEPES buffer at pH 7.3. The assay was initiated with the addition of ATP, following a fifteen minutes pre-incubation of enzyme and inhibitor at room temperature in the reaction mixture. The reaction was stopped after 30 minutes at 25° C. by the addition of 50 μL of 200 mM EDTA, pH 7.5. The Ki values were determined from the fit of the data to the Morrison tight-binding competitive inhibition equation with the enzyme concentration as a variable. (See, Morrison, J. F.

The specific assay conditions were as follows. Buffer: pH=7.5, 100 mM Tris-HCl, 75 mM NaCl, 2.5 mM CaCl2), 10 mM cysteine, 1% DMSO after all additions. Protein: 0.1 nM Kgp, isolated from culture of Porphyromonas gingivalis, as described by Pike et al. (J. Biol. Chem. 1994, 269(1), 406), and Potempa and Nguyen (Current Protocols in Protein Science. 2007, 21.20.1-21.20.27). Fluorogenic substrate: 10 μM Z-His-Glu-Lys-MCA. Time=90 minutes. Temperature=37° C. Each compound: 10 concentrations, starting at either 100 μM or 100 nM, with lower concentrations generated by serial 3-fold dilutions. By testing a range of concentrations for each compound, the concentration required to inhibit the activity of lysine gingipain by 50% (the IC50 ) was determined. Under the described assay conditions, the signal-to-noise ratio was excellent, and the Z factor was greater than 0.6. Compounds in Table 1 were tested, as well as the compounds set forth in Table 2 below.The capacities of compounds of the present invention to inhibit the activity of cathepsins B, H, K, L, and S were measured in similar assays.

Ki Determination for Genotypes 1b and 3a NS3 Protease Purified NS3 protease domain (amino acids 1-181) of the genotype 1b and 3a virus were generated as above. The internally quenched fluorogenic depsipeptide substrate Ac-DED(Edans)-EEAbuΨ[COO]ASK(Dabcyl)-NH2 and a synthetic peptide containing the hydrophobic core residues of the NS4A protein cofactor (KKGSVVIVGRIILSGRKK; NS4A peptide) were obtained from Anaspec, Inc. (San Jose, Calif.). Other chemicals and biochemicals were of reagent grade or better and were purchased from standard suppliers.Reactions were run at room temperature in buffer consisting of 50 mM HEPES, 40% glycerol, 0.05% Triton X-100, 10 mM DTT, and 10% DMSO. The final assay solutions contained 50 pM NS3 genotype 1 b protease or 200 pM genotype 3a protease, 20 μM NS4A peptide, and 4 μM substrate (genotype 1b) or 2 μM substrate (genotype 3a). Inhibitor concentrations varied from 100 nM to 5 pM in 3-fold dilutions, and no-inhibitor controls were included.Compound dilutions were made in DMSO at 20× final concentration. Reaction mixtures were prepared in 96-well assay plates. A solution of enzyme and NS4A peptide in assay buffer (25 μL volume with both reagents at 4× final concentration) was mixed with 45 μL assay buffer and 5 μL of either inhibitor or DMSO, and pre-incubated at room temperature for 1 hour. The reaction was started by addition of 25 μL substrate solution at 4× final concentration. Plates were mixed vigorously for 5-10 seconds and reactions were allowed to proceed for 90 minutes, fluorescence was measured every 30 s between 90 and 120 minutes reaction time using a Tecan InfiniTe M1000 or PerkinElmer Envision multimode plate reader with an excitation wavelength of 340 nm and an emission wavelength of 490 nm.Rates were calculated from the progress curves at steady state, in the time frame of 90-120 minutes after addition of substrate. To determine the Ki, rates were plotted as a function of inhibitor concentration, and the data were fit with equation 1 (Morrison, J. F., Biochimica et Biophysica Acta 1969, 185, 269-286) to calculate Ki app using GraphPad Prism 5. Active fraction of enzyme was determined by active site titration with known potent inhibitors. Ki was calculated from Ki app/(1+[[S]/Km]).
