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.

Assay: Receptor [35S] GTPgammaS Binding Assays: Compounds were loaded in a 384 Falcon v-bottom plate (0.5 μl/well in an 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.A smaller value for GTPγS S1P1 EC50 value indicated greater activity for the compound in the GTPγS S1P1 binding assay. Thus the compounds of the present invention may be used in treating, preventing, or curing various S1P1 receptor-related conditions. The compounds have potential use in treating, preventing, or curing autoimmune and inflammatory diseases such as multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, lupus, psoriasis, or minimizing or reducing rejection of transplanted organs.

Target: Toll-like receptor 9 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NR96
Assay: TLR7/8/9 Inhibition Reporter Assay: 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.

Target: Delta-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41143
Assay: Competition Binding Assay: The competition binding assay was conducted to determine the affinity and selectivity of the synthesized compounds to MOR over KOR and DOR. The Kd and Bmax values for [3H]NLX at MOR and [3H]DPN at KOR had been determined previously. The Kd and Bmax values for [3H]DPN at DOR were determined using varying concentrations of [3H]DPN and fixed a concentration of 30 μg DOR membrane protein and 5 μM SNC80. [3H]NLX was used to label MOR whilst [3H]DPN was used to label both DOR and KOR. The potency of the new compounds in displacing the specific binding of the radioligand was determined by linear regression analysis of Hill plots. Specific (i.e., opioid receptor-related) binding at MOR, KOR and DOR was determined as the difference in binding obtained in the absence and presence of 5 μM naltrexone, U50,488 and SNC80, respectively. The IC50 values were determined and converted to Ki values using the ChengPrusoff equation (Rosenblum, A. et al. Exp Clin Psychopharmacol. 2008, 16 (5), 405-416).

Target: Estrogen receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P03372
Assay: Estrogen Receptor Coactivator Assay: It is a competition assay, where binding of a test compound to a complex comprised of (i) His6-ERα298-554 protein representing ERα ligand-binding domain, (ii) Tb-labeled His6 antibody, (iii) a fluorescein-labeled PGC1α coactivator peptide (EAEEPSLLKKLLLAPANTQ), and (iv) estradiol, results in a decrease of the TR-FRET signal due to dissociation of the coactivator peptide. His6-ERα298-554 proteins were expressed as WT or D538G or Y537S mutants in E. coli and purified by affinity chromatography. The assay works in a homogeneous mix-and-read format. In a typical experiment, a 4 μL mixture of 0.5 nM His6-ERα298-554, 0.5 nM Tb-labeled His6 antibody, 250 nM PGC1a peptide, and 3 nM estradiol in 100 mM potassium phosphate, pH 7.4, 0.01% Tween-20, 0.02% NaN3, 5 mM DTT, was added to 40 nL test compound in DMSO and incubated overnight at room temperature. The TR-FRET 520:495 nm emission ratio was calculated and used to determine the IC50 value from a dose response curve fit to the 4-parameter logistic equation. The antagonist activity with respect to estrogen receptors in this test is given by the concentration which inhibits 50% of the estrogen receptor activity (or IC50) in nM.

Assay: EGFR Exon 19 Deletion and Exon 20 T790M Concurrent Mutations: A compound's ability in selectively inhibiting EGFR exon 19 deletion and T790M concurrent mutations can be assessed using Ba/F3 cells, a murine pro-B cell line, which have been transduced with EGFR exon 19 deletion and T790M mutation. An expression vector, pLVX-IRES puro (Clontech) coding for human EGFR E746-A750 deletion and T790M Mutation, was transfected into HEK293 cells by the Trans-Lentiviral ORF Packaging System (Thermo Scientific), to produce virus encoding EGFR exon 19 deletion and T790M mutations. Ba/F3 (DSMZ) cells maintained in RPMI 1640 medium supplemented with 10% fetal bovine serum, 200 μM L-glutamine/200 μg/mL penicillin/200 μg/mL streptomycin (Life Technology) and 10 ng/mL IL-3 (R&D system), were infected by EGFR E746-A750 deletion and T790M Mutation virus and subsequently selected by puromycin (Life Technology) selection and IL-3 depletion. Ba/F3 cells expressing EGFR E746-A750 deletion and T790M Mutation (named Ba/F3-EGFR-Del/T790M) can proliferate in the absence of IL-3. The anti-proliferative activity of compounds was determined as follows: BaF3-EGFR-Del/T790M cells seeded in 96 well plates (2500 cells/well) were treated with test compound (dissolved in DMSO) at a series of concentrations (4-fold dilution, top concentration: 10,000 nM). The plates were incubated for 72 h in a 37° C. incubator with 5% CO2, and the number of viable cells in each well were measured indirectly by CellTiter 96® Aqueous One Solution Cell Proliferation Assay (Promega; this assay is a colorimetric method for determining the number of viable cells through measurement of their metabolic activity by detection of enzymatic conversion of tetrazolium salts into blue formazan derivatives).

Assay: [35S]GTPgammaS Binding Assay: The human APJ receptor was cloned by polymerase chain reaction and the gene encoding the receptor was subcloned in pFLAG-CMV¿-3 expression vector (Sigma, Saint Louis, Mo. USA) in-house at Amgen. A GTPγS binding assay was performed on membranes prepared from CHO cells stably expressing human APJ receptor. The optimum experimental conditions for the concentrations of GDP, MgCl2, and NaCl in the assay buffer were initially determined. The assay was performed in assay buffer [20 mM HEPES, pH 7.5, 5 mM MgCl2, and 0.1% (w/v) BSA with 200 mM NaCl, 3 μM GDP] and membranes expressing human APJ receptor/well along with WGA PS beads. The reaction was initiated by addition of 0.2 nM [35S]GTPγS (Perkin Elmer Life and Analytical Sciences, Waltham USA) in the absence or presence of various ligands and incubated at RT for 90 min. Nonspecific binding was determined in the presence of 100 μM GTPγS and was always less than 0.2% of total binding. All the results presented are means of several independent experiments and analyzed by non-linear regression methods using commercially available program Prism (GraphPad, San Diego, Calif.) to obtain EC50.

Assay: TLR7/8/9 Inhibition Reporter Assay: 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.

Target: Proto-oncogene tyrosine-protein kinase receptor Ret (SINGLE PROTEIN), Homo sapiens
UniProt: P07949
Assay: RET G810R Mutant Assay: The potency of a compound inhibiting G81 OR mutant RET kinase was determined using CisBio's HTRF Kinease-TK assay technology. The assays contained G81OR mutant RET produced at Array Biopharma, Inc. (1 nM enzyme p1982 Lot. No. 160713. The kinase was incubated with 250 nM TK-substrate biotin (CisBio, part of Catalog #62TK0PEC) and 1 mM ATP along with test compound in a buffer consisting of 25 mM HEPES, pH 7.4, 10 mM MgCl2, 0.01% Triton X-100, and 2% DMSO in a volume of 8 μL. Compounds were typically prepared as a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 60-min incubation at 22° C., the reaction was quenched by adding 8 μL of quench solution containing 31.25 nM Sa-XL665 and 1×TK-Ab-Cryptate in HTRF detection buffer (all from CisBio, part of cat #62TK0PEC). After a 1-h incubation at 22° C., the extent of reaction was determined using a PerkinElmer EnVision multimode plate reader via HTRF dual wavelength detection, and the percent of control (POC) was calculated using a ratiometric emission factor. One hundred POC was determined using no test compounds, and 0 POC was determined using pre-quenched control reactions. A 4-parameter logistic curve was fit to the POC values as a function of the concentration of compound, and the IC50 value was the point where the best-fit curve crossed 50 POC.
