Target: Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit gamma isoform (SINGLE PROTEIN), Homo sapiens
UniProt: P48736
Assay: PI 3-Kinase HTRF Assay: 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 1x reaction buffer) is added per well for a final concentration of 0.25-0.3 ug/ml kinase and 10 uM PIP2. The plate is sealed and incubated for 15 minutes at room temperature. To start the reaction, 3.5 ul of ATP (diluted in 1x reaction buffer) is added per well for a final concentration of 10 uM 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.

UniProt: O60674
Assay: Biochemical HTRF Assay : The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer #PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction. Plates were shaken and centrifuged and then incubated 60 minutes at room temperature and then read on a Perkin Elmer Envision (λex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading.

UniProt: Q12809
Assay: Activity Assay: HERG: The pre- and post-compound hERG current was evoked by a single voltage pulse consisting of a 20 s period holding at −70 mV, a 160 ms step to −60 mV (to obtain an estimate of leak), a 100 ms step back to −70 mV, a 1 s step to +40 mV, a 2 s step to −30 mV, and finally a 500 ms step to −70 mV. In between the pre- and post-compound voltage pulses, there was no clamping of the membrane potential. Currents were leak-subtracted based on the estimate of current evoked during the +10 mV step at the start of the voltage pulse protocol. The current signal was sampled at 2.5 k Hz. For each compound, the IC50 value was determined.

UniProt: P51449
Assay: Binding Assay : The binding of potential ligands to RORγ is measured by competition with [3H]25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA). The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 μg/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 μM to 0.28 nM, for 10 min at rt in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% glycerol (Sigma Cat # G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat # RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined.

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: FGFR Enzymatic Assay 2: 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. GraphPad prism3 was used to analyze the data. The IC50 values were derived by fitting the data to the equation for a sigmoidal dose-response with a variable slope. Y=Bottom+(Top−Bottom)/(1+10^((Log IC50−X)*HillSlope)) where X is the logarithm of concentration and Y is the response. Compounds having an IC50 of 1 μM or less are considered active. The compounds of the invention were found to be selective inhibitors of FGFR3 and/or FGFR4 according to the FGFR Enzymatic Assays. Compounds of Formula (I′) and (I) and all the compounds as described herein have been tested and exhibit an IC50 of less than 1 μM. Table 3 provides IC50 data for compounds of the invention assayed in the FGFR Enzymatic Assay after dilution in assay buffer, added to the plate and pre-incubated for 5 to 10 minutes.

Assay: JAK/TYK2 Assay: 10 mM test compound stock or 1 mM control compound stock (tofocitinib, ruxolitinib or staurosporine) in DMSO was diluted to 0.4 mM in DMSO. A 3-fold series dilution was then performed in DMSO to generate 10 different compound concentrations. The assay was carried out in 384-well white plate. 0.5 uL of 40× compound DMSO solution at different concentrations was mixed with 10 uL 2× enzyme prepared in reaction buffer (20 mM HEPES, 10 mM MgCl2, 0.01% Tween, 1 mM DTT, pH 7.5). 10 uL 2× substrate mixture prepared in reaction buffer was then added to start the reaction. A short spin was done to settle down all solutions to the bottom of the plate. Final concentrations of test compound in the reaction mixture were 10000, 3333, 1111, 370, 123, 41.2, 13.7, 4.57, 1.52and 0.51 nM. Concentrations of control compound were ten times less. Enzymatic reaction was conducted at 25° C. for 1-2 hours. 10 uL of Kinase Glo Reagents was added to stop the reaction and generate the luminescent signal which was measured using Envision. Luminescence signal was inversely related to kinase activity. Reaction mixture which did not contain enzyme served as negative control. The mixture without any compound was the positive control.

UniProt: P52333
Assay: Enzyme Assay: 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) fluorophore 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).

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: Biochemical HTRF Assay : The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer #PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction. Plates were shaken and centrifuged and then incubated 60 minutes at room temperature and then read on a Perkin Elmer Envision (λex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading.

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: Receptor [35S] GTPgammaS Binding Assays: (S1P1 GTPgammaS/S1P3 GTPgammaS): Compounds were loaded in a 384 Falcon v-bottom plate (0.5 l/well in a 11 point, 3-fold dilution). Membranes prepared from S1P1/CHO cells or EDG3-Gal5-bla HEK293T cells (EDG3 equivalent S1P3) were added to the compound plate (40 l/well, final protein 3 μg/well) with MULTIDROP®. [35S]GTP (1250 Ci/mmol, Perkin Elmer) was diluted in assay buffer: 20 mM HEPES, pH7.5, 10 mM MgCl2, 150 mM NaCl, 1 mM EGTA (ethylene glycol tetraacetic acid), 1 mM DTT (Dithiothreitol), 10 μM GDP, 0.1% fatty acid free BSA, and 10 μg/ml Saponin to 0.4 nM. 40 μl of the [35S] GTP solution was added to the compound plate with a final concentration of 0.2 nM. The reaction was kept at room temperature for 45 min. At the end of incubation, all the mixtures in the compound plate were transferred to Millipore 384-well FB filter plates via the VELOCITY11® Vprep liquid handler. The filter plate was washed with water 4 times by using the manifold Embla plate washer and dried at 60° C. for 45 min. MicroScint 20 scintillation fluid (30 μl) was added to each well for counting on the Packard TOPCOUNT®. EC50 is defined as the agonist concentration that corresponds to 50% of the Ymax (maximal response) obtained for each individual compound tested. The EC50 for Example 689 was determined to be 5.7 nM in the assay utilizing membranes prepared from S1P1/CHO cells. The EC50 for Example 689 was determined to be >2000 nM in the assay utilizing membranes prepared from EDG3-Gal5-bla HEK293T cells.A smaller value for GTPγS S1P1 EC50 value indicated greater activity for the compound in the GTPγS S1P1 binding assay. A larger value for the GTPγS S1P3 EC50 value indicated less activity in the GTPγS S1P3 binding assay. Example 689, which is the phosphate ester of Example 672, possessed activity as an agonist of S1P1 and is selective over S1P3. Example 697, which is the phosphate ester of Example 681, possessed activity as an agonist of S1P1 and is selective over S1P3. Thus the compounds of the present invention may be used in treating, preventing, or curing various S1P1 receptor-related conditions while reducing or minimizing the side effects due to S1P3 activity. The selectivity of the compounds of the present invention indicate their potential use in treating, preventing, or curing autoimmune and inflammatory diseases such as multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, lupus, psoriasis, or vascular diseases, while reducing or minimizing possible side effects due to S1P3 activity. Other potential uses of the compounds of the present invention include minimizing or reducing rejection of transplanted organs, while reducing or minimizing side effects due to S1P3 activity.

Compound (SMILES): c1ccc2c(c1)nc(-c1cnc[nH]1)n2[C@H]1C[C@H]2CCC[C@@H](C1)N2[C@@H]1C[C@@H]2CCC[C@@H](C2)C1
InChIKey: BIQRROWUCAZDMH-WMXKIEPZSA-N
Target: Delta-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41143
Assay: Radioligand Binding Assay: Radioligand dose-displacement assays used 0.2 nM [3H]-Naltrindole (NEN; 33.0 Ci/mmole) with 10-20 μg membrane protein (recombinant delta opioid receptor expressed in CHO-K1 cells; Perkin Elmer) in a final volume of 500 μL binding buffer (5 mM MgCl2, 5% DMSO, 50 mM Trizma base, pH 7.4). Non-specific binding was determined in the presence of 25 μM unlabeled naloxone. All reactions were performed in 96-deep well polypropylene plates for 1 h at a temperature of about 25° C. Binding reactions were determined by rapid filtration onto 96-well Unifilter GF/C filter plates (Packard) presoaked in 0.5% polyethylenimine (Sigma-Aldrich). Harvesting was performed using a 96-well tissue harvester (Packard) followed by five filtration washes with 500 μL ice-cold binding buffer. Filter plates were subsequently dried at 50° C. for 1-2 hrs. Fifty μL/well scintillation cocktail (MicroScint20, Packard) was added and plates were counted in a Packard Top-Count for 1 min/well.
