Assay: Enzymatic Inhibition Assay: 11-point dosing series were made for each compound by serially diluting 1:3 or 1:4 in DMSO, with point 12 being a DMSO control. From the serial dilution plates, sample was transferred to a 384 wells assay plate (#781280, Greiner, Monroe, N.C.) using Labcyte Echo (Sunnyvale, Calif.), or Biosero ATS (San Diego, Calif.). The compounds were tested in duplicate. Column 12 was used for positive controls, and column 24 contained negative controls with no enzyme added. A compound from our internal collection, with inhibitory activity for JAK isoforms, was used as a reference compound. The final concentration of DMSO was ≤0.25% in a 20 μL reaction. Assay conditions for each of the proteins are summarized in Table 3. The enzyme reaction was initiated by the addition of 10 μL of 2× enzyme and ATP mixture to 10 μL of 2× substrate solution prepared in reaction buffer (50 mM MOPS pH 7.5, 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20). The Tyk2 enzyme was pre-incubated with 2 mM ATP for 30 min prior to the reaction initiation. Immediately after the addition of the enzyme to the reaction mixture, the plate was centrifuged at 1000 rpm for 1 minute and incubated at 25° C. for 45 minutes for JAK 3 and 90 minutes for JAK1, JAK2 and Tyk2. The reaction was quenched by the addition of 20 μL of 0.5% TFA containing 0.15 μM of internal standard peptide using Multidrop Combi reagent dispenser (Thermo Scientific, Waltham, Mass.). Several wells in column 24 were typically used for the product standard curve. After the quench, the assay plate was centrifuged at 3000 rpm for 3 minutes and sealed with pierceable aluminum foil (Cat #06644-001, Agilent) using a PlateLoc (Agilent Technologies, Santa Clara, Calif.). The plates then were transferred on to the RapidFire for the MS analysis. Compound inhibition was assessed by a decrease of the phosphorylated product levels in sample wells compared to the non-inhibited enzyme reaction. The assay conditions for the above assays are shown in Table 3 and the results of Ex. 1-209 as tested in these assays are shown in Table 4.TABLE 3Assay conditions for JAK family enzyme assays* [p], [ATP], [Substrate], [IS],Enzyme nM μM μM nMJAK1-JH1JH2 8.0 12.5 200 100JAK2-JH1JH2 7.0 or 3.6 30 40 100JAK3-JH1JH2 2.0 150 40 100Tyk2-JH1JH2   25 or 14.7 50 200 100*Reaction buffer: 50 mM MOPS, pH 7.5 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20; IS stands for internal standard peptide; p stands for phospho-peptide (product); Substrate stands for peptide.

Assay: Sodium Influx Assay (In Vitro Assay): This sodium influx assay employs the use of the cell permeable, sodium sensitive dye ANG2 to quantify sodium ion influx through sodium channels which are maintained in an open state by use of sodium channel modulators. This high throughput sodium influx assay allows for rapid profiling and characterization of sodium channel blockers.In general, Trex HEK293 cells were stably transfected with an inducible expression vector containing the full-length cDNA coding for the desired human sodium channel α-subunit and with an expression vector containing full length cDNA coding for the β1-subunit. Sodium channel expressing cell lines were induced with tetracycline (1 μg/mL) and plated on 384-well PDL-coated plates at a density of 25K-30K cells/well in culture media (DMEM, containing 10% FBS and 1% L-glutamine). After overnight incubation (37° C., 5% CO2), culture media was removed and cells were loaded with 5 uM ANG2 dye for 1-1.5 h in Buffer 1 (155 mM NMDG, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, 10 mM HEPES, 10 mM glucose, adjusted with Tris to pH 7.4). Access dye was removed and cells were incubated with test compounds for 1 hr in buffer 1 containing sodium channel modulator(s) at room temperature. Hamamatsu FDSS μCell was used to perform a 1:1 addition of Na/K challenge buffer (140 mM NaCl, 20 mM HEPES, 1 mM CaCl2, 15 mM KCl, 1 mM MgCl2, 10 mM glucose, adjusted with Tris to pH 7.4) and simultaneously read plates at excitation wavelength of 530 nm and emission wavelength set at 558 nm. Percent inhibition of sodium ion influx was calculated for each test compound at each test concentration to determine the IC50 values.

Assay: Enzymatic Inhibition Assay: 11-point dosing series were made for each compound by serially diluting 1:3 or 1:4 in DMSO, with point 12 being a DMSO control. From the serial dilution plates, sample was transferred to a 384 wells assay plate (#781280, Greiner, Monroe, N.C.) using Labcyte Echo (Sunnyvale, Calif.), or Biosero ATS (San Diego, Calif.). The compounds were tested in duplicate. Column 12 was used for positive controls, and column 24 contained negative controls with no enzyme added. A compound from our internal collection, with inhibitory activity for JAK isoforms, was used as a reference compound. The final concentration of DMSO was ≤0.25% in a 20 μL reaction. Assay conditions for each of the proteins are summarized in Table 3. The enzyme reaction was initiated by the addition of 10 μL of 2× enzyme and ATP mixture to 10 μL of 2× substrate solution prepared in reaction buffer (50 mM MOPS pH 7.5, 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20). The Tyk2 enzyme was pre-incubated with 2 mM ATP for 30 min prior to the reaction initiation. Immediately after the addition of the enzyme to the reaction mixture, the plate was centrifuged at 1000 rpm for 1 minute and incubated at 25° C. for 45 minutes for JAK 3 and 90 minutes for JAK1, JAK2 and Tyk2. The reaction was quenched by the addition of 20 μL of 0.5% TFA containing 0.15 μM of internal standard peptide using Multidrop Combi reagent dispenser (Thermo Scientific, Waltham, Mass.). Several wells in column 24 were typically used for the product standard curve. After the quench, the assay plate was centrifuged at 3000 rpm for 3 minutes and sealed with pierceable aluminum foil (Cat #06644-001, Agilent) using a PlateLoc (Agilent Technologies, Santa Clara, Calif.). The plates then were transferred on to the RapidFire for the MS analysis. Compound inhibition was assessed by a decrease of the phosphorylated product levels in sample wells compared to the non-inhibited enzyme reaction. The assay conditions for the above assays are shown in Table 3 and the results of Ex. 1-209 as tested in these assays are shown in Table 4.TABLE 3Assay conditions for JAK family enzyme assays* [p], [ATP], [Substrate], [IS],Enzyme nM μM μM nMJAK1-JH1JH2 8.0 12.5 200 100JAK2-JH1JH2 7.0 or 3.6 30 40 100JAK3-JH1JH2 2.0 150 40 100Tyk2-JH1JH2   25 or 14.7 50 200 100*Reaction buffer: 50 mM MOPS, pH 7.5 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20; IS stands for internal standard peptide; p stands for phospho-peptide (product); Substrate stands for peptide.

Assay: Aurora-A, Aurora-B, JAK1, JAK2, JAK3 Enzyme Assays: The inhibitory activity of compounds against AURKA, AURKB, JAK1, JAK2 and JAK3 was determined in Z'-LYTE® assays run by ThermoFisher Scientific as part of their SelectScreen® Biochemical Kinase Profiling Service. The Z'-LYTE® biochemical assay format employs a fluorescence-based, coupled-enzyme format and is based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to proteolytic cleavage. The peptide substrate is labeled with two fluorophoresone at each endthat make up a FRET pair. In the primary reaction, the kinase transfers the gamma-phosphate of ATP to a single tyrosine, serine or threonine residue in a synthetic FRET-peptide. In the secondary reaction, a site-specific protease recognises and cleaves non-phosphorylated FRET-peptides. Phosphorylation of FRET-peptides suppresses cleavage by the Development Reagent. Cleavage disrupts FRET between the donor (i.e., coumarin) and acceptor (i.e., fluorescein) fluorophores on the FRET-peptide, whereas uncleaved, phosphorylated FRET-peptides maintain FRET. A ratiometric method, which calculates the ratio (the Emission Ratio) of donor emission to acceptor emission after excitation of the donor fluorophore at 400 nm, is used to quantitate reaction progress. Both cleaved and uncleaved FRET-peptides contribute to the fluorescence signals and therefore to the Emission Ratio. The extent of phosphorylation of the FRET-peptide can be calculated from the Emission Ratio. The Emission Ratio will remain low if the FRET-peptide is phosphorylated (i.e., no kinase inhibition) and will be high if the FRET-peptide is non-phosphorylated (i.e., kinase inhibition).10 point three-fold dilution compound concentration-response curves, with a top concentration of 10 μM were generated from 10 mM stocks of compound solubilised in DMSO. All assays were performed in black, non-binding, low volume Corning 384-well plates (cat. #4514, Corning), in a total reaction volume of 10 μL and 1% (v/v) final DMSO concentration. 2.4 μL Kinase Buffer (50 mM HEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA), 5 μL 2× Peptide/Kinase mixture (detailed below for each kinase) and 2.5 μL 4×ATP Solution (prepared in Kinase Buffer) were added separately to the compound plates, placed on a plate shaker for 30 sec, and then incubated for 60 mins at room temperature. The kinase reaction was then quenched by the addition of 5 μL of Development Reagent (ThermoFisher Scientific proprietary). Assay plates were placed on a plate shaker for 30 sec, incubated for 60 mins at room temperature, and then read using a fluorescence plate reader. IC50 values were calculated using XLfit software (IDBS Ltd, Surrey, UK), with the curve fit to model number 205 (sigmoidal dose-response model).

Assay: Enzymatic Inhibition Assay: 11-point dosing series were made for each compound by serially diluting 1:3 or 1:4 in DMSO, with point 12 being a DMSO control. From the serial dilution plates, sample was transferred to a 384 wells assay plate (#781280, Greiner, Monroe, N.C.) using Labcyte Echo (Sunnyvale, Calif.), or Biosero ATS (San Diego, Calif.). The compounds were tested in duplicate. Column 12 was used for positive controls, and column 24 contained negative controls with no enzyme added. A compound from our internal collection, with inhibitory activity for JAK isoforms, was used as a reference compound. The final concentration of DMSO was ≤0.25% in a 20 μL reaction. Assay conditions for each of the proteins are summarized in Table 3. The enzyme reaction was initiated by the addition of 10 μL of 2× enzyme and ATP mixture to 10 μL of 2× substrate solution prepared in reaction buffer (50 mM MOPS pH 7.5, 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20). The Tyk2 enzyme was pre-incubated with 2 mM ATP for 30 min prior to the reaction initiation. Immediately after the addition of the enzyme to the reaction mixture, the plate was centrifuged at 1000 rpm for 1 minute and incubated at 25° C. for 45 minutes for JAK 3 and 90 minutes for JAK1, JAK2 and Tyk2. The reaction was quenched by the addition of 20 μL of 0.5% TFA containing 0.15 μM of internal standard peptide using Multidrop Combi reagent dispenser (Thermo Scientific, Waltham, Mass.). Several wells in column 24 were typically used for the product standard curve. After the quench, the assay plate was centrifuged at 3000 rpm for 3 minutes and sealed with pierceable aluminum foil (Cat #06644-001, Agilent) using a PlateLoc (Agilent Technologies, Santa Clara, Calif.). The plates then were transferred on to the RapidFire for the MS analysis. Compound inhibition was assessed by a decrease of the phosphorylated product levels in sample wells compared to the non-inhibited enzyme reaction. The assay conditions for the above assays are shown in Table 3 and the results of Ex. 1-209 as tested in these assays are shown in Table 4.TABLE 3Assay conditions for JAK family enzyme assays* [p], [ATP], [Substrate], [IS],Enzyme nM μM μM nMJAK1-JH1JH2 8.0 12.5 200 100JAK2-JH1JH2 7.0 or 3.6 30 40 100JAK3-JH1JH2 2.0 150 40 100Tyk2-JH1JH2   25 or 14.7 50 200 100*Reaction buffer: 50 mM MOPS, pH 7.5 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20; IS stands for internal standard peptide; p stands for phospho-peptide (product); Substrate stands for peptide.

Target: Sodium channel protein type 1 subunit alpha (SINGLE PROTEIN), Homo sapiens
UniProt: P35498
Assay: Sodium Influx Assay (In Vitro Assay): This sodium influx assay employs the use of the cell permeable, sodium sensitive dye ANG2 to quantify sodium ion influx through sodium channels which are maintained in an open state by use of sodium channel modulators. This high throughput sodium influx assay allows for rapid profiling and characterization of sodium channel blockers.In general, Trex HEK293 cells were stably transfected with an inducible expression vector containing the full-length cDNA coding for the desired human sodium channel α-subunit and with an expression vector containing full length cDNA coding for the β1-subunit. Sodium channel expressing cell lines were induced with tetracycline (1 μg/mL) and plated on 384-well PDL-coated plates at a density of 25K-30K cells/well in culture media (DMEM, containing 10% FBS and 1% L-glutamine). After overnight incubation (37° C., 5% CO2), culture media was removed and cells were loaded with 5 uM ANG2 dye for 1-1.5 h in Buffer 1 (155 mM NMDG, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, 10 mM HEPES, 10 mM glucose, adjusted with Tris to pH 7.4). Access dye was removed and cells were incubated with test compounds for 1 hr in buffer 1 containing sodium channel modulator(s) at room temperature. Hamamatsu FDSS μCell was used to perform a 1:1 addition of Na/K challenge buffer (140 mM NaCl, 20 mM HEPES, 1 mM CaCl2, 15 mM KCl, 1 mM MgCl2, 10 mM glucose, adjusted with Tris to pH 7.4) and simultaneously read plates at excitation wavelength of 530 nm and emission wavelength set at 558 nm. Percent inhibition of sodium ion influx was calculated for each test compound at each test concentration to determine the IC50 values.
