Target: Cathepsin D (SINGLE PROTEIN), Homo sapiens
UniProt: P07339
Assay: In-Vitro Fluorescence Assay: In order to identify modulators of cathepsin D activity, a continuous enzymatic test was carried out with a synthetic peptide which carries a fluorescent group (MCA=(7-methoxycoumarin-4-yl)acetyl) which is quenched by energy transfer from a Dpn (2,4 dinitrophenyl) group on the same molecule, in Greiner 384-well nb microtitre plates. Cleavage of the peptidic substrate by cathepsin D causes an increase in the fluorescence intensity. In order to determine the efficacy of substances, the time-dependent increase in the fluorescence intensity in the presence of the substance was compared with the time-dependent increase in fluorescence in the absence of substances. The reference substance used was pepstatin A (Sigma-Aldrich). The substrate used was MCA-GKPILFFRLK(Dnp)d-RNH2 (Enzo Life Sciences, Lörrach). The enzyme employed was cathepsin D isolated from the human liver (Sigma-Aldrich) in a final concentration of 1.4 nM. The test was carried out in 100 mM sodium acetate buffer, 1.25% (v/v) of DMSO, 0.25% (w/v) of Chaps, pH 5.5. 2 μl of each substance solution with serially diluted substance concentration were added to in each case 4 μl of cathepsin D solution and incubated at room temperature for 10 min. The reaction was started by addition of 2 μl of substrate solution (final concentration 5 μM). After carrying out a starting-point fluorescence measurement (excitation wavelength 340 nm/emission wavelength 450 nm) using an Envision multilabel reader (Perkin Elmer), the reaction was incubated at room temperature for 60 min. The amount of peptide fragment cleaved off during the reaction time was subsequently measured by determination of the increase in the fluorescence intensity at 450 nm (excitation wavelength 340 nm).

Assay: Human D1 Receptor Binding Assay: D1 binding assays were performed using over-expressing LTK human cell lines. To determine basic assay parameters, ligand concentrations were determined from saturation binding studies where the Kd for [3H]-SCH23390 was found to be 1.3 nM. From tissue concentration curve studies, the optimal amount of tissue was determined to be 1.75 mg/mL per 96 well plate using 0.5 nM of [3H]-SCH23390. These ligand and tissue concentrations were used in time course studies to determine linearity and equilibrium conditions for binding. Binding was at equilibrium with the specified amount of tissue in 30 minutes at 37° C. From these parameters, Ki values were determined by homogenizing the specified amount of tissue for each species in 50 mM Tris (pH 7.4 at 4° C.) containing 2.0 mM MgCl2 using a Polytron and spun in a centrifuge at 40,000×g for 10 minutes. The pellet was resuspended in assay buffer [50 mM Tris (pH 7.4@ RT) containing 4 mM MgSO4 and 0.5 mM EDTA]. Incubations were initiated by the addition of 200 μL of tissue to 96-well plates containing test drugs (2.5 μL) and 0.5 nM [3H]-SCH23390 (50 μL) in a final volume of 250 μL. Non-specific binding was determined by radioligand binding in the presence of a saturating concentration of (+)-Butaclamol (10 μM), a D1 antagonist. After a 30 minute incubation period at 37° C., assay samples were rapidly filtered through Unifilter-96 GF/B PEI-coated filter plates and rinsed with 50 mM Tris buffer (pH 7.4 at 4° C.). Membrane bound [3H]-SCH23390 levels were determined by liquid scintillation counting of the filterplates in Ecolume. The IC50 value (concentration at which 50% inhibition of specific binding occurs) was calculated by linear regression of the concentration-response data in Microsoft Excel. Ki values were calculated according to the Cheng-Prusoff equation.

Assay: HotSpot Assay: In vitro profiling protein kinases was performed using the HotSpot assay platform. Briefly, specific kinase/substrate pairs along with required cofactors were prepared in reaction buffer. Compounds were delivered into the reaction, followed 15-20 minutes later by addition of a mixture of ATP (Sigma, St. Louis Mo.) and 33P ATP (Perkin Elmer, Waltham Mass.) to a final concentration of 10 μM. Reactions were carried out at room temperature for 120 min, followed by spotting of the reaction mixtures onto P81 ion exchange filter paper (Whatman Inc., Piscataway, N.J.). Unbound phosphate was removed by extensive washing of filters in 0.75% phosphoric acid. After subtraction of background derived from control reactions containing inactive enzyme, kinase activity data was expressed as the percent of remaining kinase activity in test samples compared to vehicle (dimethyl sulfoxide) reactions. IC50 values and curve fits were obtained using Prism (GraphPad Software).Reaction Conditions: Buffer Conditions: 20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/mL BSA, 0.1 mM Na3VO4, 2 mM DTT, and 1% DMSO. ATP concentration: 10 μM. Reaction Time: 2 hours. Compound 3 was tested at 10 concentrations as follows with a comparison to the common kinase inhibitor reference compound staurosporine. Compounds were tested in a 10-point IC50 mode with 3-fold serial dilution starting at 10 uM. Control Compound was tested in a 10-point IC50 with 3-fold serial dilution starting at 20 uM.

Determinations were made using purified human Factor XIa at a final concentration of 40 pM (Sekisui Diagnostics) and the synthetic substrate, Z-Gly-Pro-Arg-AFC, TFA salt (Sigma #C0980) at a concentration of 10004.Activity assays were performed by diluting a stock solution of substrate at least tenfold to a final concentration ≤0.1 Km into a solution containing enzyme or enzyme equilibrated with inhibitor. Times required to achieve equilibration between enzyme and inhibitor were determined in control experiments. Initial velocities of product formation in the absence (Vo) or presence of inhibitor (Vi) were measured. Assuming competitive inhibition, and that unity is negligible compared Km/[S], [I]/e, and [I]/e (where [S], [I], and e respectively represent the total concentrations, of substrate, inhibitor and enzyme), the equilibrium constant (Ki) for dissociation of the inhibitor from the enzyme can be obtained from the dependence of Vo/Vi on [I] shown in the following equation.V o /V i=1+[I]/Ki.

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.

After incubation, the reaction was terminated by the addition of EDTA and the phosphorylated and non-phosphorylated peptides separated using a LABCHIP® 3000 Reader (Caliper Life Sciences). Controls consisted of assays that did not contain compound, and backgrounds consisted of assays that contained enzyme and substrate but had EDTA from the beginning of the reaction to inhibit kinase activity. Compounds were tested in dose-response format, and the inhibition of kinase activity was calculated at each concentration of compound. The inhibition data were fit using a curve-fitting program to determine the IC50; i.e., the concentration of compound required to inhibit 50% of kinase activity.

Assay: ERalpha Binding Assay: The ability of compounds to bind to isolated Estrogen Receptor Alpha Ligand binding domain (ER alphaLBD (GST)) was assessed in competition assays using a LanthaScreen Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) detection end-point. For the LanthaScreen TR-FRET endpoint, a suitable fluorophore (Fluormone ES2, ThermoFisher, Product code P2645) and recombinant human Estrogen Receptor alpha ligand binding domain, residues 307-554 (expressed and purified in-house) were used to measure compound binding. The assay principle is that ER alpha-LBD (GST) is added to a fluorescent ligand to form a receptor/fluorophore complex. A terbium-labelled anti-GST antibody (Product code PV3551) is used to indirectly label the receptor by binding to its GST tag, and competitive binding is detected by a test compound's ability to displace the fluorescent ligand, resulting in a loss of TR-FRET signal between the Tb-anti-GST antibody and the tracer. The assay was performed as follows with all reagent additions carried out using the Beckman Coulter BioRAPTR FRD microfluidic workstation:1. Acoustic dispense 120 nL of the test compound into a black low volume 384 well assay plates.2. Prepare 1× ER alpha-LBD/Tb-antiGST Ab in ES2 screening buffer and incubate for 15 minutes.3. Dispense 6 μL of the 1× AR-LBD/Tb-anti-GST Ab reagent into each well of the assay plate followed by 6 μL of Fluorophore reagent into each well of the assay plate4. Cover the assay plate to protect the reagents from light and evaporation, and incubate at room temperature for 4 hours.5. Excite at 337 nm and measure the fluorescent emission signal of each well at 490 nm and 520 nm using the BMG PheraSTAR.Compounds were dosed directly from a compound source microplate containing serially diluted compound (4 wells containing 10 mM, 0.1 mM, 1 μM and 10 nM final compound respectively) to an assay microplate using the Labcyte Echo 550. The Echo 550 is a liquid handler that uses acoustic technology to perform direct microplate-to-microplate transfers of DMSO compound solutions and the system can be programmed to transfer multiple small nL volumes of compound from the different source plate wells to give the desired serial dilution of compound in the assay which is then back-filled to normalise the DMSO concentration across the dilution range.

Assay: Binding Assay: The affinity of FXR ligands for the ligand binding domain of FXR was determined using a commercially available human FXR ligand binding assay (LanthaScreen, Thermofisher Cat # PV4833). The purified ligand binding domain of human FXR tagged with GST (glutathiones-S-transferase) is incubated with a terbium labelled anti-GLT antibody and a fluorescein-labelled SRC2-2 peptide (LKEKHKILHRLLQDSSSPV (SEQ ID NO.: 1)). Binding of FXR ligands to the FXR ligand binding domain promotes binding of the fluorescein-labelled SRC2-2 peptide. This causes a FRET signal between the terbium-labelled anti-GST antibody and the fluorescein-labelled SRC peptide which are both bound to the FXR ligand binding domain.Test compounds are dissolved in DMSO and a 3-fold serial dilution series is generated, then further diluted into assay buffer. The compounds are mixed with 5 nM GST-tagged FXR ligand binding domain, 5 nM Tb-labelled anti-GST antibody and 500 nM fluorescein-labelled SRC2-2 peptide in a pH7.4 buffer. The reaction is incubated at room temperature for 1 hour, then the FRET signal is measured as the ratio of the 520 nm/495 nm emission following excitation at 340 nm. The change in FRET signal is plotted against the test article concentration and fit to a 3-parameter logistical equation.

To this solution is added test compounds or vehicle control (DMSO) and BodiPY ligand (structure below). The plate is shaken for 1-2 min, sealed and incubated for 1 hour at rt in the dark. The TR-FRET signal is measured using BMG Pherastar (Lanthascreen protocol on BMG Pherastar). Excitation was carried out at 320 nm, and the ratio of emission of BodiPY (520 nm) to terbium (486 nm) was determined. Concentration response curves are generated by calculating the excitation increase in test compound-treated samples relative to DMSO-treated controls. For the assay method described above, test compound percent inhibition values at a single concentration are calculated relative to control (DMSO) treated samples. Compound concentration response curves are fitted to generate IC50 values from those curves. One skilled in the art will appreciate that these values generated either as percentage inhibition at a single concentration or IC50 values are subject to experimental variation.

Biochemistry. 1994, 33, 14393-14399.) was used as the substrate for Factor D (104 mM). Hydrolysis of this compound by Factor D liberated a free sulfhydryl group which is then reacted with 5,5′-dithiobis(2nitrobenzoic acid) producing an intense yellow color (Habeeb, A. F. S. A. Reaction of protein sulfhydryl groups with Ellman's Reagent. Methods in Enzymol. 1976, 25, 457-464). The assays were performed in 96 well microtiter plates and rates of hydrolysis were monitored at 405 nm on a Biotek Synergy H1 plate reader. Hydrolysis rates were reported as change in mOD/min. The assay was conducted in 100 mM HEPES, 500 mM NaCl, pH 7.5 containing 10% DMSO in a final volume of 50 μL per well.
