Assay: TR-FRET Assay for ERBB Kinases: All compounds and PROTACs were serially diluted in three-fold increments using 100% DMSO, followed by an intermediate 10-fold dilution using Buffer A (50 mM HEPES, pH 7.5, 50 mM NaCl, 10 mM MgCl2, 1 mM DTT, and 0.1% Pluronic F-68). Two microliters of serially diluted compound or PROTAC were then transferred to black 384-well Proxiplates (PerkinElmer, #6008260) using an Integra Viaflo96. Next, 10 uL of protein kinase in Buffer A was added to each well of the assay plate and pre-incubated with compound for 10 minutes. Kinase reactions were then initiated by addition of 5 uL substrate mix containing 3 mM ATP and 30 uM fluorescein-labeled Poly-GluTyr (Thermo Fisher, #PV3610) in Buffer A and allowed to proceed for 10 minutes at room temperature. Reactions were quenched by addition of a 5 uL mixture containing 5 nM LanthaScreen® Tb-pY20 Antibody (Thermo Fisher, #PV3552) and 40 mM EDTA in Buffer A. Assay plates were then read using a Synergy2 (Biotek Instruments, Winooski, Vt.) via excitation thru a 340/20 nm bandpass filter and emission collected thru 490/10 nm (donor) and 520/25 nm (acceptor) bandpass filters. The final kinase concentrations used for each 15 uL reaction were as follows: 0.2 nM EGFR Exon20NPG (SignalChem, #E10-132GG), 0.1 nM wild type EGFR (BPS Bioscience, #40187), 0.3 nM EGFR L858R/T790M/C797S (BPS Bioscience, #40351), 0.1 nM EGFR L858R (BPS Bioscience, #40189), 0.4 nM L858R/T790M (BPS Bioscience, #40350), InM EGFR Dell9 (SignalChem, #E10-122JG), 10 nM EGFR Dell9 T790M (SignalChem, #E10-122KG), 0.3 nM Her2 (BPS Bioscience, #40230), 15 nM Her2 InsYVMA (SignalChem, #E27-13BG).

Assay: Kinase Assay: Kd: For most assays, kinase-tagged T7 phage strains were prepared in an E. coli host derived from the BL21 strain. E. coli were grown to log-phase and infected with T7 phage and incubated with shaking at 32° C. until lysis. The lysates were centrifuged and filtered to remove cell debris. The remaining kinases were produced in HEK-293 cells and subsequently tagged with DNA for qPCR detection. Streptavidin-coated magnetic beads were treated with biotinylated small molecule ligands for 30 minutes at room temperature to generate affinity resins for kinase assays. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligand and to reduce nonspecific binding. Binding reactions were assembled by combining kinases, liganded affinity beads, and test compounds in 1× binding buffer (20% SeaBlock, 0.17×PBS, 0.05% Tween 20, 6 mM DTT). All reactions were performed in polystyrene 96-well plates in a final volume of 0.135 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer (1×PBS, 0.05% Tween 20). The beads were then re-suspended in elution buffer (1×PBS, 0.05% Tween 20, 0.5 μM non-biotinylated affinity ligand) and incubated at room temperature with shaking for 30 minutes. The kinase concentration in the eluates was measured by qPCR.

Assay: In Vitro Affinity: The in vitro affinity of the compounds of the present invention for the CXCR1 and CXCR2 receptors is determined on a functional test of β-arrestin recruitment type after activation of the receptor.It has been demonstrated that activation by CXCL8 of the CXCR2 receptor in cells of the PathHunter HEK293-CXCR2 line or of the CXCR1 receptor in cells of the U2OS h CXCR1 β-arrestin line leads to the recruitment of β-arrestin (Richardson, R. M., R. J. Marjoram, L. S. Barak, R. Snyderman. 2003. Role of the cytoplasmic tails of CXCR1 and CXCR2 in mediating leukocyte migration, activation, and regulation. J. Immunol. 170: 2904-2911).To evaluate the direct interaction of the CXCR2 or CXCR1 receptor with β-arrestin 2, a test of β-arrestin 2 recruitment for CXCR2 or CXCR1 based on complementation of the β-galactosidase enzyme (Olson K. R., Eglen R. M., Beta-galactosidase complementation: a cell-based luminescent assay platform for drug discovery. Assay Drug Dev. Technol. 2007 February; 5(1); 137-44), as established by DiscoveRx Corporation was used. Stimulation of these two cell lines with CXCL8 (10 nM) induces the recruitment of β-arrestin 2, as indicated by a significant increase in the induction factor. All the CXCR2 antagonists are tested in a dose-dependent manner and the concentration corresponding to 50% inhibition of the response is determined (IC50=concentration of half-inhibition).β-Arrestin Recruitment Test: PathHunter HEK293-CXCR2 or U2OS hCXCR1 β-arrestin cells (DiscoveRx Corporation) were seeded overnight at 10 000 cells/well (384-well format) in 20 μl of Opti MEM I medium. Preincubation with the antagonist or the vehicle for 30 minutes at 37° C. and 5% CO2 was followed by 60 minutes of stimulation with CXCL8 at 37° C. and 5% CO2. The cells were then placed at room temperature for 30 minutes. The PathHunter detection reagent (DiscoveRx Corporation) was added. After incubation for 60 minutes at room temperature, the β-galactosidase induced by the luminescence during the β-arrestin-CXCR2 interaction was measured for 0.3 s in an Envision 2102 Multilabel Reader (PerkinElmer Life and Analytical Sciences). The data are analysed via a non-linear curve procedure using the XLFit4 (IDBS) exploitation software, and the IC50 values are determined.

Assay: P2X7 FLIPR Assay: 1321N1 cells expressing the recombinant human or rat P2X7 channel was cultured in HyQ DME/(HyClone/Dulbecco's Modified Eagle Medium) high glucose supplemented with 10% Fetal Bovine Serum (FBS) and appropriate selection marker. Cells were seeded at a density of 25000 cells/well (96-well clear bottom black walled plates) in 100 μl volume/well. On the day of the experiment, cell plates were washed with assay buffer, containing (in mM): 130 NaCl, 2 KCl, 1 CaCl2, 1 MgCl2, 10 HEPES, 5 glucose; pH 7.40 and 300 mOs. After the wash, cells were loaded with the Calcium-4 dye (Molecular Device) and incubated in the dark for 60 minutes. Test compounds were prepared at 250× the test concentration in neat DMSO. Intermediate 96-well compound plates were prepared by transferring 1.2 μL of the compound into 300 μL of assay buffer. A further 3× dilution occurred when transferring 50 μL/well of the compound plate to 100 μL/well in the cell plate. Cells were incubated with test compounds and dye for 30 minutes. Calcium dye fluorescence was monitored in FLIPR as the cells were challenged by adding 50 μL/well of BzATP (final concentration is 250 μM BzATP (human and rat)). The fluorescence change was measured 180 seconds after adding the agonist. Peak fluorescence was plotted as a function of BzATP concentration using Origin 7 software.

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.

Assay: In Vitro Affinity: The in vitro affinity of the compounds of the present invention for the CXCR1 and CXCR2 receptors is determined on a functional test of β-arrestin recruitment type after activation of the receptor.It has been demonstrated that activation by CXCL8 of the CXCR2 receptor in cells of the PathHunter HEK293-CXCR2 line or of the CXCR1 receptor in cells of the U2OS h CXCR1 β-arrestin line leads to the recruitment of β-arrestin (Richardson, R. M., R. J. Marjoram, L. S. Barak, R. Snyderman. 2003. Role of the cytoplasmic tails of CXCR1 and CXCR2 in mediating leukocyte migration, activation, and regulation. J. Immunol. 170: 2904-2911).To evaluate the direct interaction of the CXCR2 or CXCR1 receptor with β-arrestin 2, a test of β-arrestin 2 recruitment for CXCR2 or CXCR1 based on complementation of the β-galactosidase enzyme (Olson K. R., Eglen R. M., Beta-galactosidase complementation: a cell-based luminescent assay platform for drug discovery. Assay Drug Dev. Technol. 2007 February; 5(1); 137-44), as established by DiscoveRx Corporation was used. Stimulation of these two cell lines with CXCL8 (10 nM) induces the recruitment of β-arrestin 2, as indicated by a significant increase in the induction factor. All the CXCR2 antagonists are tested in a dose-dependent manner and the concentration corresponding to 50% inhibition of the response is determined (IC50=concentration of half-inhibition).β-Arrestin Recruitment Test: PathHunter HEK293-CXCR2 or U2OS hCXCR1 β-arrestin cells (DiscoveRx Corporation) were seeded overnight at 10 000 cells/well (384-well format) in 20 μl of Opti MEM I medium. Preincubation with the antagonist or the vehicle for 30 minutes at 37° C. and 5% CO2 was followed by 60 minutes of stimulation with CXCL8 at 37° C. and 5% CO2. The cells were then placed at room temperature for 30 minutes. The PathHunter detection reagent (DiscoveRx Corporation) was added. After incubation for 60 minutes at room temperature, the β-galactosidase induced by the luminescence during the β-arrestin-CXCR2 interaction was measured for 0.3 s in an Envision 2102 Multilabel Reader (PerkinElmer Life and Analytical Sciences). The data are analysed via a non-linear curve procedure using the XLFit4 (IDBS) exploitation software, and the IC50 values are determined.

Assay: Kinase Assay: Kd: For most assays, kinase-tagged T7 phage strains were prepared in an E. coli host derived from the BL21 strain. E. coli were grown to log-phase and infected with T7 phage and incubated with shaking at 32° C. until lysis. The lysates were centrifuged and filtered to remove cell debris. The remaining kinases were produced in HEK-293 cells and subsequently tagged with DNA for qPCR detection. Streptavidin-coated magnetic beads were treated with biotinylated small molecule ligands for 30 minutes at room temperature to generate affinity resins for kinase assays. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligand and to reduce nonspecific binding. Binding reactions were assembled by combining kinases, liganded affinity beads, and test compounds in 1× binding buffer (20% SeaBlock, 0.17×PBS, 0.05% Tween 20, 6 mM DTT). All reactions were performed in polystyrene 96-well plates in a final volume of 0.135 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer (1×PBS, 0.05% Tween 20). The beads were then re-suspended in elution buffer (1×PBS, 0.05% Tween 20, 0.5 μM non-biotinylated affinity ligand) and incubated at room temperature with shaking for 30 minutes. The kinase concentration in the eluates was measured by qPCR.
