Assay: Kinase Assay: Inhibition of phosphorylation of a synthetic peptide was measured in an HTRF-based assay using the TK substrate-Biotin from the Cisbio HTRFKinEASE TK kit. First, 2 μl of TK solution (TK substrate-biotin in kinase buffer [1× enzymatic buffer from HTRFKinEASE TK kit, 1 mM DTT]) is added to a plate containing 1 μl prediluted compound (final assay concentration DMSO: 0.75%). Then, 5 μl kinase-ATP mix (prepared in kinase buffer) is added to the wells and the plates are incubated at RT for 20-30 min. For all four kinases a concentration of ATP that corresponded to the Km for ATP was used. The final concentrations of buffers, substrate, kinase and ATP were: JAK1: 50 mM Hepes buffer pH 7.0, 0.01% BSA, 10 mM MgCl2, 1 mM DTT, 7 μM ATP, 50 nM SEB, 1 μM TK Substrate-Biotin and 5 ng JAK1; JAK2: 50 mM Hepes buffer pH 7.0, 0.01% BSA, 5 mM MgCl2, 1 mM DTT, 4 μM ATP, 1 μM TK Substrate-Biotin and 0.1 ng JAK2; JAK3: 50 mM Hepes buffer pH 7.0, 0.01% BSA, 5 mM MgCl2, 1 mM DTT, 2 μM ATP, 1 μM TK Substrate-Biotin and 0.3 ng JAK3; TYK2: 50 mM Hepes buffer pH 7.0, 0.01% BSA, 5 mM MgCl2, 1 mM DTT, 13 μM ATP, 50 nM SEB, 1 μM TK Substrate-Biotin and 0.8 ng TYK2. Thereafter, the kinase reaction is stopped by adding 4 μl detection mix (final concentrations: 50 mM Hepes buffer pH 7.0, 0.01% BSA, 0.8 M KF, 20 mM EDTA, 42 nM Streptavidin-XL665 and 1:400 STK Ab Cryptate) and the plates are incubated overnight in the dark. The HTRF signal is read using an Envision plate reader.

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.

Target: Beta-secretase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y5Z0
Assay: Biochemical FRET Based Assay : This assay is a Fluorescence Resonance Energy Transfer Assay (FRET) based assay. The substrate for this assay contains the ¿Swedish¿ Lys-Met/Asn-Leu mutation of the amyloid precursor protein (APP) beta-secretase cleavage site. This substrate also contains two fluorophores: (7-methoxycoumarin-4-yl) acetic acid (Mca) is a fluorescent donor with excitation wavelength at 320 nm and emission at 405 nm and 2,4-Dinitrophenyl (Dnp) is a proprietary quencher acceptor. The distance between those two groups has been selected so that upon light excitation, the donor fluorescence energy is significantly quenched by the acceptor, through resonance energy transfer. Upon cleavage by the beta-secretase, the fluorophore Mca is separated from the quenching group Dnp, restoring the full fluorescence yield of the donor. The increase in fluorescence is linearly related to the rate of proteolysis.Briefly in a 384-well format recombinant BACE2 protein in a final concentration of 0.4 μg/ml is incubated for 450 minutes at room temperature with 10 μM substrate in incubation buffer (50 mM Citrate buffer pH 5.0, 0.05% PEG, no DMSO) in the absence or presence of compound. Next the amount of proteolysis is directly measured by fluorescence measurement at T=0 and T=450 (excitation at 320 nm and emission at 405 nm). Results are expressed in RFU (Relative Fluorescence Units), as difference between T450 and TO.

Assay: Biochemical JAK Assay: A panel of four LanthaScreen JAK biochemical assays (JAK1, 2, 3 and Tyk2) were carried in a common kinase reaction buffer (50 mM HEPES, pH 7.5, 0.01% Brij-35, 10 mM MgCl2, and 1 mM EGTA). Recombinant GST-tagged JAK enzymes and a GFP-tagged STAT1 peptide substrate were obtained from Life Technologies.Serially diluted compounds were pre-incubated with each of the four JAK enzymes and the substrate in white 384-well microplates (Corning) at ambient temperature for lh. ATP was subsequently added to initiate the kinase reactions in 10 μL total volume, with 1% DMSO. The final enzyme concentrations for JAK1, 2, 3 and Tyk2 are 4.2 nM, 0.1 nM, 1 nM, and 0.25 nM respectively; the corresponding Km ATP concentrations used are 25 μM, 3 μM, 1.6 μM, and 10 μM; while the substrate concentration is 200 nM for all four assays. Kinase reactions were allowed to proceed for 1 hour at ambient temperature before a 10 μL preparation of EDTA (10 mM final concentration) and Tb-anti-pSTAT1 (pTyr701) antibody (Life Technologies, 2 nM final concentration) in TR-FRET dilution buffer (Life Technologies) was added. The plates were allowed to incubate at ambient temperature for lh before being read on the EnVision reader (Perkin Elmer). Emission ratio signals (520 nm/495 nm) were recorded and utilized to calculate the percent inhibition values based on DMSO and background controls.For dose-response analysis, percent inhibition data were plotted vs. compound concentrations, and IC50 values were determined from a 4-parameter robust fit model with the Prism software (GraphPad Software). Results were expressed as pIC50 (negative logarithm of IC50) and subsequently converted to pKi (negative logarithm of dissociation constant, Ki) using the Cheng-Prusoff equation.Test compounds having a higher pKi value in each of the four JAK assays show greater inhibition of JAK activity. Compounds of the invention tested in this assay typically exhibited pKi values between about 7 and about 10.3

Assay: Prolabel Quantification of IKZF1, IKZF2, or GSPT1 Protein Levels in 293GT Cells: The Prolabel system from DiscoverX was used to develop high-throughput and quantitative assays to measure changes in IKZF1, IKZF2, and GSPT1 protein levels in response to compounds. The prolabel tag is derived from the alpha fragment of beta galactosidase and has the following protein sequence: mssnslavvlqrrdwenpgvtqlnrlaahppfaswrnseeartdrpsqqlrslnge. The complementary fragment of beta-galactosidase (from DiscoverX), is added to the prolabel tag to form an active beta galactosidase enzyme whose activity can be precisely measured. In this way, the levels of a fusion protein with the prolabel tag can be quantified in cell lysates.Lentiviral vectors, based on the Invitrogen pLenti6.2/V5 DEST backbone, were constructed that placed the prolabel tag upstream of IKZF1, IKZF2, or GSPT1 and expressed the fusion protein from a CMV promoter.To ensure moderate and consistent expression of the prolabel fusion proteins across all cells in the population, stable cell lines were constructed from cells expressing a single copy of the construct. Lentivirus packaged with the constructs was made using the Virapower kit from Invitrogen. Strongly adherent 293GT cell, GripTite 293 MSR cells from Thermo Fisher Scientific (Catalog number: R79507), were infected with the virus at low multiplicity of infection and selected by 5 μg/mL blasticidin for 2 weeks.

This assay was run in agonist mode, to characterize compounds of the invention that exhibit LXR agonist activity, and in antagonist mode to characterize compounds of the invention having LXR antagonist activity and which cause a concentration-dependent release of the co-activator peptide in the presence of the full LXR agonist T0901317. The interaction between glutathione S-transferase (GST)-tagged, recombinant human LXRα-LBD or LXRβ-LBD and fluorescein-conjugated co-activator peptide SRC2-3 (Cat# PV4588, Life Technologies, Grand Island, N.Y.) was measured via time resolved-fluorescence resonance energy transfer (TR-FRET). The assay was performed in 96-well half-area black Opti-plates (Cat# 3686, Corning, Lowell, Mass.) in 20 mM TRIS-HCl buffer, pH 8, containing 150 mM NaCl and 5 mM DDT in a total volume of 80 μL. Test compounds were dissolved in DMSO, and semi-log (3.162×) serial dilutions were also prepared in DMSO, as 40× solutions.

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: 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.

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.
