[35S]-GTPgamaS Binding Assay: Selected Compounds of the Examples were evaluated at Millipore Corporation, USA, using S1P1 receptor; [35S]-GTPgamaS binding assay. A [35S]-GTPgamaS binding assay at Millipore was conducted by GPCR Profiler Custom Service Laboratory, Temecula, Calif., Millipore, Inc. to monitor dose-dependent agonist selectivity for selected Examples against the S1P1 receptors. The assay was completed with sample compounds subjected to an eight-point, four-fold dose response curve with starting concentration of 10 uM. Selectivity was determined upon initial addition of compounds followed by a 30 minute incubation at 30° C. Following compound incubation, bounded [35S]-GTPgamaS was determined by filtration and scintillation counting. Independently, selected compounds were evaluated for S1P1 and S1P3 agonistic activity. The S1P1 assay system was GTPgama-S35 binding in membranes from CHO K1 cells, expressing S1P1 human receptor. The S1P3 assay system was calcium mobilization in CHO K1 cells expression.[35S]-GTPgamaS Binding Assay: Selected Compounds of the Examples were evaluated at Millipore Corporation, USA, using S1P1 receptor; [35S]-GTPgamaS binding assay.

A [35S]-GTPgamaS binding assay at Millipore was conducted by GPCR Profiler Custom Service Laboratory, Temecula, Calif., Millipore, Inc. to monitor dose-dependent agonist selectivity for selected Examples against the S1P1 receptors. The assay was completed with sample compounds subjected to an eight-point, four-fold dose response curve with starting concentration of 10 uM. Selectivity was determined upon initial addition of compounds followed by a 30 minute incubation at 30° C. Following compound incubation, bounded [35S]-GTPgamaS was determined by filtration and scintillation counting. Independently, selected compounds were evaluated for S1P1 and S1P3 agonistic activity. The S1P1 assay system was GTPgama-S35 binding in membranes from CHO K1 cells, expressing S1P1 human receptor. The S1P3 assay system was calcium mobilization in CHO K1 cells expression.[35S]-GTPgamaS Binding Assay: Selected Compounds of the Examples were evaluated at Millipore Corporation, USA, using S1P1 receptor; [35S]-GTPgamaS binding assay.

[35S]-GTPgamaS Binding Assay: Selected Compounds of the Examples were evaluated at Millipore Corporation, USA, using S1P1 receptor; [35S]-GTPgamaS binding assay. A [35S]-GTPgamaS binding assay at Millipore was conducted by GPCR Profiler Custom Service Laboratory, Temecula, Calif., Millipore, Inc. to monitor dose-dependent agonist selectivity for selected Examples against the S1P1 receptors. The assay was completed with sample compounds subjected to an eight-point, four-fold dose response curve with starting concentration of 10 uM. Selectivity was determined upon initial addition of compounds followed by a 30 minute incubation at 30° C. Following compound incubation, bounded [35S]-GTPgamaS was determined by filtration and scintillation counting. Independently, selected compounds were evaluated for S1P1 and S1P3 agonistic activity. The S1P1 assay system was GTPgama-S35 binding in membranes from CHO K1 cells, expressing S1P1 human receptor. The S1P3 assay system was calcium mobilization in CHO K1 cells expression.[35S]-GTPgamaS Binding Assay: Selected Compounds of the Examples were evaluated at Millipore Corporation, USA, using S1P1 receptor; [35S]-GTPgamaS binding assay.
