Assay: Inhibition of Lysine Gingipain: The capacities of compounds of the present invention to inhibit the activity of lysine gingipain were measured in a fluorogenic assay similar to those described by Barret (Biochemical Journal. 1980, 187(3), 909). 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.

Target: Kallikrein-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P06870
Assay: Kallikrein Assay: The effectiveness of a compound of the present invention as an inhibitor of Kallikrein can be determined using a relevant purified serine protease, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Assays were conducted at rt or at 37° C. Hydrolysis of the substrate resulted in release of amino trifluoromethylcoumarin (AFC), which was monitored spectrofluorometrically by measuring the increase in emission at 510 nm with excitation at 405 nm. A decrease in the rate of fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as the inhibitory constant, Ki.Kallikrein determinations were made in 50 mM HEPES buffer at pH 7.4 containing 150 mM NaCl, 5 mM CaCl2, and 0.1% PEG 8000 (polyethylene glycol; Fisher Scientific). Determinations were made using purified Human plasma Kallikrein at a final concentration of 0.5 nM (Enzyme Research Laboratories) and the synthetic substrate, Acetyl-K-P-R-AFC (Sigma # C6608) at a concentration of 100 mM.Activity assays were performed by diluting a stock solution of substrate at least tenfold to a final concentration ≤0.2 Km into a solution containing enzyme or enzyme equilibrated with inhibitor. Times required to achieve equilibration between enzyme and inhibitor were determined in control experiments. The reactions were performed under linear progress curve conditions and fluorescence increase measured at 405 Ex/510 Em nm. Values were converted to percent inhibition of the control reaction (after subtracting 100% Inhibition value). IC50 was determined by inflection point from a four parameter logistic curve fit. Ki was calculated using the Cheng Prusoff equation, Ki=IC50/(1+([S]/Km)).

Assay: Inhibition Assays: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/mL). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration of 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 μL 1N HCl followed by 160 μL CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid.

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). In order to allow the detection and quantification of the peptides in the capillary system, the peptides carry a fluorescent label (fluorescein). With this label the peptides can be quantified by fluorescence intensity through the instruments laser and detection system (LC3000, Caliper Life Sciences).The assays were performed in 384-well, low volume microtiter assay plates in a final reaction volume of 9 ul. Dose-response curves were generated by incubating 10 nM of each kinase together with 2 μm of the fluorescently labeled substrate peptide 5-Fluo-Ahx-KKYQAEEN-T-YDEYENKK-amid (10 mM stock solution in DMSO) in 50 mM Hepes pH 7.5, 0.02% Tween 20, 0.02% BSA, 1 mM DTT, 10 m Na3VO4, 10 mM If-Glycerolphosphate, 1 mM MgCl2, 12 mM MnCl2 (ALK1 and ALK6 7 mM) and 15 μm ATP for 60 min at 30° C. in the presence or absence of compound diluted in DMSO. Kinase reaction were terminated by adding 15 ul STOP buffer (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35.Plates with terminated kinase reactions were transferred to the Caliper LC3000 workstation (Caliper Technologies Corp., Mountain View, USA) for reading. The relative amount of phosphorylated peptide r, was calculated using the heights of the substrate peak, s, and the product peak, p: r=p/(p+s).

Assay: Inhibition Assay of PI3K: An exemplary system is PI 3-Kinase (human) HTRF Assay from Upstate. The assay can be carried out according to the procedures suggested by the manufacturer. Briefly, the assay is a time resolved FRET assay that indirectly measures PIP3 product formed by the activity of a PI3-K. The kinase reaction is performed in a microtitre plate (e.g., a 384 well microtitre plate). The total reaction volume is approximately 20 ul per well. In the first step, each well receives 2 ul of test compound in 20% dimethylsulphoxide resulting in a 2% DMSO final concentration. Next, approximately 14.5 ul of a kinase/PIP2 mixture (diluted in 1× reaction buffer) is added per well for a final concentration of 0.25-0.3 ug/ml kinase and 10 μM PIP2. The plate is sealed and incubated for 15 minutes at room temperature. To start the reaction, 3.5 ul of ATP (diluted in 1× reaction buffer) is added per well for a final concentration of 10 μM ATP. The plate is sealed and incubated for 1 hour at room temperature. The reaction is stopped by adding 5 ul of Stop Solution per well and then 5 ul of Detection Mix is added per well. The plate is sealed, incubated for 1 hour at room temperature, and then read on an appropriate plate reader.

Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at a final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Blue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Assay: Inhibition of Lysine Gingipain: The capacities of compounds of the present invention to inhibit the activity of lysine gingipain were measured in a fluorogenic assay similar to those described by Barret (Biochemical Journal. 1980, 187(3), 909). 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.

UniProt: P06870
Assay: Kallikrein Assay: The effectiveness of a compound of the present invention as an inhibitor of Kallikrein can be determined using a relevant purified serine protease, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Assays were conducted at rt or at 37° C. Hydrolysis of the substrate resulted in release of amino trifluoromethylcoumarin (AFC), which was monitored spectrofluorometrically by measuring the increase in emission at 510 nm with excitation at 405 nm. A decrease in the rate of fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as the inhibitory constant, Ki.Kallikrein determinations were made in 50 mM HEPES buffer at pH 7.4 containing 150 mM NaCl, 5 mM CaCl2, and 0.1% PEG 8000 (polyethylene glycol; Fisher Scientific). Determinations were made using purified Human plasma Kallikrein at a final concentration of 0.5 nM (Enzyme Research Laboratories) and the synthetic substrate, Acetyl-K-P-R-AFC (Sigma # C6608) at a concentration of 100 mM.Activity assays were performed by diluting a stock solution of substrate at least tenfold to a final concentration ≤0.2 Km into a solution containing enzyme or enzyme equilibrated with inhibitor. Times required to achieve equilibration between enzyme and inhibitor were determined in control experiments. The reactions were performed under linear progress curve conditions and fluorescence increase measured at 405 Ex/510 Em nm. Values were converted to percent inhibition of the control reaction (after subtracting 100% Inhibition value). IC50 was determined by inflection point from a four parameter logistic curve fit. Ki was calculated using the Cheng Prusoff equation, Ki=IC50/(1+([S]/Km)).

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. Compounds are typically prepared in a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. 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
