Target: E3 ubiquitin-protein ligase Mdm2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q00987
Assay: FRET Assay: An HDM2 FRET assay was developed to assess the compounds' inhibitory activity towards binding of p53 protein. A truncated version of HDM2 with residues 17 to 125 (containing p53 binding surface, Science (1994) 265, 346-355), with N-terminal His and Thioredoxin tag was generated in pET32a expression vector and expressed in E. coli strain BL21(DE3)Rosetta. Protein was purified using Ni-affinity chromatography, followed by size exclusion chromatography using Superdex 75 26/60 column. To assess inhibition of p53 binding to HDM2, a FITC labeled 8-mer peptide (sequence: Ac-Phe-Arg-Dpr-Ac6c-(6-Br)Trp-Glu-Glu-Leu-NH2; Anal Biochem. 2004 Aug. 1; 331(1):138-46) with strong affinity towards p53 binding pocket of HDM2 was used. The HDM2 assay buffer contained 1× Phosphate Buffered Saline (Invitrogen, Cat#14190), 0.01% BSA (Jackson ImmunoResearch, Cat#001-000-162), 0.01% Tween-20. In the 1× assay buffer recombinant HDM2 protein, peptide and Lumi4-Tb Cryptate-conjugate mouse anti-6×His antibody (cisbio, Cat# Tb61HISTLB) were added and transferred to ProxiPlate PLUS (PerkinElmer, Cat#6008269), containing compounds so that final DMSO concentration is 0.1%. Final concentrations of reagents in the assay wells are 0.5 nM HDM2, 0.25 nM anti HIS (Tb label) antibody and 3 nM peptide. After two hour incubation at room temperature in a humidified chamber plates were read on EnVision plate reader with the following settings: excitation: UV, 340 nM, two emission filters: 520 nm and 495 nm respectively. Ratio of em520/em495 was used to calculate % inhibition and to obtain IC50 with 4-parameter logistic equation.

Tested compounds were dissolved in DMSO, and semi-log (3.162×) serial dilutions of the compounds were prepared in the same solvent. Two μL of the DMSO solutions were mixed with 28 μL of 8.6 nM 25-hydroxy[26,27-3H]-cholesterol and 50 μL of 24 nM RORγ LBD. The plate was shaken at 700 rpm for 20 min and incubated for 10 min at rt, after which 40 μL of poly-Lys YSi SPA beads (PerkinElmer, Cat. #RPNQ0010) were added to achieve 50 μg of the beads per well. The plate was incubated on an orbital shaker for 20 min and then for 10 min without agitation at rt. SPA signal for tritium beta radiation was registered on PerkinElmer Microbeta plate reader. Percent inhibition values were calculated based on the high signal obtained with DMSO control and the low signal observed with 10 μM standard RORγ inverse agonist T0901317 (SigmaAldrich, Cat. #T2320). The percent inhibition vs. concentration data were fit into a four-parameter model, and IC50 values were calculated from the fit as the concentrations corresponding to the inflection points on the dose-response curves.

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: Biological Assay: The kinase IC50 was determined by a commercialized CISBIO kinase detection kit, HTRF KinEASE-STK S2 kit (62ST2PEC). ROCK2 (01-119) employed in the reaction was purchased from Carna Biosciences.Before the assay, the following working solutions as needed were formulated with corresponding reagents according to the instruction of the kinase detection kit: 1×kinase buffer, 5×STK-52 substrate working solution (1.5 μM) and 5×ATP working solution (1.5 μM), 5×ROCK2 kinase working solution, 4×Streptavidin-XL665 working solution, and 4×STK-Ab-Cryptate 2 detection solution. Then the assay was performed according to the following procedure.A solution of a compound at a concentration of 10000 nM was prepared with the 1×kinase buffer containing 2.5% DMSO. Gradient dilution of the solution of the compound was performed with the kinase buffer containing DMSO, so as to obtain solutions of a test compound at 9 different concentrations. In addition to wells of test compounds, a positive well (containing all the reagents except the compound) and a negative well (containing all the reagents except the test compound and kinase) were set. Except for the control wells (positive and negative wells), a solution of a test compound (4 μL) was added to each of the reaction wells, and a solution of 2.5% DMSO was added to the control wells. Then the substrate (2 μM, i.e., 2 μL. 5×STK-S2 substrate working solution) was added to each of the reaction wells. The 5×ROCK2 kinase working solution (2 μL, containing 1.4 ng ROCK2 kinase) was added to each of the reaction wells except for the negative well, the volume of which was made up with the 1×kinase buffer (2 μL). The 5×ATP working solution (2 μL) was added to each of the reaction wells, and the mixtures were incubated at room temperature for 2 hours. After the kinase reaction was complete, the 4×Streptavidin-XL665 working solution was added to each of the reaction wells, the solutions were mixed, followed by immediate addition of the 4×STK-Ab-Cryptate 2 detection solution (5 μL), and the mixtures were incubated at room temperature for 1 hour. The fluorescence signal was read on ENVISION (Perkinelmer) (excitation wavelength: 320 nm, and emission wavelength: 665 nm and 615 nm). The inhibitory rate in each well was calculated based on the fluorescence intensity value: ER (Emission Ratio)=(fluorescence intensity at 665 nm/fluorescence intensity at 615 nm); inhibitory rate=(ERpositive−ERtest compound)/(ERpositive−ERnegative)*100%. Curves were plotted and fitted to obtain the median inhibitory concentration (IC50) of each teat compound with the PRISM 5.0 software.

Assay: Competitive Displacement Assay: Membrane protein from CHO (Chinese Hamster Ovarian) cells that stably expressed one type of the cloned human opioid receptor were incubated with 12 different concentrations of the compound in the presence of 0.25 nM [3H]DAMGO, 0.2 nM [3H]naltrindole or 1 nM [3H]U69,593 in a final volume of 1 mL of 50 mM Tris-HCl, pH 7.5 at 25° C. Incubation times of 60 min were used for [3H]DAMGO and [3H]U69,593. Because of a slower association of [3H]naltrindole with the receptor, a 3 h incubation was used with this radioligand. Samples incubated with [3H]naltrindole also contained 10 mM MgCl2 and 0.5 mM phenylmethylsulfonyl fluoride. Nonspecific binding was measured by inclusion of 10 μM naloxone. The binding was terminated by filtering the samples through Schleicher & Schuell No. 32 glass fiber filters using a Brandel 48-well cell harvester. The filters were subsequently washed three times with 3 mL of cold 50 mM Tris-HCl, pH 7.5, and were counted in 2 mL Ecoscint A scintillation fluid. For [3H]naltrindole and [3H]U69,593 binding, the filters were soaked in 0.1% polyethylenimine for at least 60 min before use.

Assay: General RORgamma SPA 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. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.
Measurement: IC50 = 123 nM (pChEMBL 6.909999847412109)
