Target: Histone-lysine N-methyltransferase SMYD3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9H7B4
Assay: SMYD3 Biochemical Assay: The assays were all performed in a buffer consisting of 25 mM Tris-Cl pH 8.0, 1 mM TCEP, 0.005% BSG, and 0.005% Tween 20, prepared on the day of use. Compounds in 100% DMSO (1 ul) were spotted into a 384-well white opaque OptiPlate using a Bravo automated liquid handling platform outfitted with a 384-channel head (Agilent Technologies). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMYD3, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the SMYD3 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD3 for 30 min at room temperature, then a cocktail (10 ul) containing SAM and MEKK2 was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: SMYD3 was 0.4 nM, 3H-SAM was 8 nM, MEKK2 was 12 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (10 ul) to a final concentration of 100 uM, which dilutes the 3H-SAM to a level where its incorporation into MEKK2 is no longer detectable. Radiolabeled MEKK2 was detected using a scintillation proximity assay (SPA). 10 uL of a 10 mg/mL solution of SPA beads in 0.5 M citric acid was added and the plates centrifuged at 600 rpm for 1 min to precipitate the radiolabeled MEKK2 onto the SPA beads. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of 3H-labeled MEKK2 as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).% Inhibition Calculation% ⁢ ⁢ inh = 100 - ( dpm cmpd - dpm min dpm max - dpm min ) × 100Where dpm=disintegrations per minute, cmpd=signal in assay well, and min and max are the respective minimum and maximum signal controls.Four-Parameter IC50 FitY = Bottom + ( Top - Bottom ) ( 1 + ( X IC 50 ) Hill ⁢ ⁢ CoefficientWhere top and bottom are the normally allowed to float, but may be fixed at 100 or 0 respectively in a 3-parameter fit.

Assay: Fluorescence Polarization Anisotropy Competition Assay: Compound affinity was measured using a fluorescence polarization anisotropy competition assay. Anisotropy measurements were carried out in 384-well, black, flat-bottom plates (Greiner Bio-one, Monroe, N.C., USA). The assay was run using a fluorescein isothiocyanate-labeled BH3 peptide derived from Bak (FITC-AHx-GQVGRQLAIIGDDINR-NH2) that was purchased from GenScript (Piscataway, N.J.) at >95% purity and used without further purification. 10 nM FITC-Bak peptide and 14 nM recombinant Mcl-1 (residues 172-327) were added to assay buffer (3 mM dithiothreitol, 50 mM NaCl, 20 mM Tris, pH 7.5). For selectivity assays, 40 nM Bcl-2 (residues 1-207A96T,G110R, Δ35-91, replaced with Bcl-xL35-50) or 4 nM Bcl-xL (residues 1-209, loop 45-86 deleted) were incubated with 10 nM FITC-Bak in assay buffer.Compounds are diluted in DMSO in a 10-point, 3-fold serial dilution scheme. 2.5 uL compound is added to 47.5 uL of assay buffer containing FITC-Bak and protein, for a final DMSO concentration of 5% and a top concentration of 20 uM. A FITC-Bak peptide alone (100% inhibition) and peptide plus protein (0% inhibition) control is included on each assay plate. The plate was mixed and incubated for 90 minutes at room temperature. Anisotropy is measured at excitation wavelength 480 nm and emission wavelength 535 nm using an EnVision Multi-label plate reader (PerkinElmer, Wellesley, Mass., USA). Fluorescence anisotropy is plotted against compound concentration to generate an IC50 (inhibitor concentration at which 50% of bound peptide is displaced) by fitting the data to a 4-parameter logistic model using XLFit software (Guildford, Surrey, UK). IC50 is converted to a binding dissociation constant (Ki value)

Assay: IMAP-FP Assay: Activated ERK2 activity was determined in an IMAP-FP assay (Molecular Devices). Using this assay format, the potency (IC50) of each compound was determined from a 10 point (1:3 serial dilution, 3 μM starting compound concentration) titration curve using the following outlined procedure. To each well of a black Corning 384-well plate (Corning Catalog #3575), 7.5 nL of compound (3333 fold dilution in final assay volume of 25 μL) was dispensed, followed by the addition of 15 μL of kinase buffer (tween containing kinase buffer, Molecular Devices) containing 0.0364 ng/mL (0.833 nM) of phosphorylated active hERK2 enzyme. Following a 15 minute compound & enzyme incubation, each reaction was initiated by the addition of 10 μL kinase buffer containing 2.45 μM ERK2 IMAP substrate peptides and 75 μM ATP. The final reaction in each well of 25 μL consists of 0.5 nM hERK2, 900 nM unlabeled peptide, 80 nM labeled-peptide, and 30 μM ATP. Phosphorylation reactions were allowed to proceed for 60 minutes and were immediately quenched by the addition of 60 μL IMAP detection beads (1:1000 dilutions) in IMAP binding buffer (Molecular Devices) with 24 mM NaCl. Plates were read on EnVision reader after 60 minutes binding equilibration using Fluorescence Polarization protocol (Perkin Elmer).

Assay: Binding Assay (ELISA): The ELISA assay was performed in streptavidin coated plates which were preincubated with 200 ul per well of 1 μg ml−1 biotinylated IP3 peptide. The plates were ready to use for MDM2 binding after washing the plate with PBS.Compounds and control solutions in DMSO aliquoted in 96-well plates were pre-incubated in a final 2.5-5% (v/v) DMSO concentration at room temperature (for example 20C.) for 20 min with 190 ul aliquots of optimized concentrations of in vitro translated MDM2, before transfer of the MDM2-compound mixture to the b-IP3 streptavidin plates, and incubation at 4C. for 90 min. After washing three times with PBS to remove unbound MDM2, each well was incubated at 20C. for 1 hour with a TBS-Tween (50 mM Tris pH7.5; 150 mM NaCl; 0.05% Tween 20 nonionic detergent) buffered solution of primary mouse monoclonal anti-MDM2 antibody (Ab-5, Calbiochem, used at a 1/10000 or 1/200 dilution depending on the antibody stock solution used), then washed three times with TBS-Tween before incubation for 45 mins at 20C. with a TBS-Tween buffered solution of a goat-anti-mouse horseradish peroxidase (HRP) conjugated secondary antibody (used at 1/20000 or 1/2000 depending on the antibody stock solution). The unbound secondary antibody was removed by washing three times with TBS-Tween. The bound HRP activity was measured by enhanced chemiluminesence (ECL, Amersham Biosciences) using the oxidation of the diacylhydrazide substrate, luminol, to generate a quantifiable light signal. The percentage of MDM2 inhibition at a given concentration is calculated as the [1−(RLU detected in the compound treated sample−RLU negative DMSO control)÷(RLU of DMSO positive and negative controls)]x100 or as the (RLU detected in the compound treated sample ÷ RLU of DMSO controls)x100.

Assay: Factor D Esterolytic Assay: An established esterolytic assay for the measurement of Factor D activity and inhibition of Factor D activity was used (Kam, C. M.; McRae, B. J.; Harper, J. W.; Niemann, M. A.; Volanakis, J. E.; Powers, J. C. Human complement proteins D, C2, and B Active site mapping with peptide thioester substrates. J Biol. Chem. 1987, 262, 3444-3451). For this assay Z-Lys-SBzl, 1.29 mM (Kim, S.; Narayana, S. V. L; Volanakis, J. E. Mutational analysis of the substrate binding site of human complement Factor D. 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.

Assay: Inhibition Assay: The procedure for measuring the 11β-HSD1-inhibitory activity is as follows. The enzyme reaction and the measurement were carried out using a 384-well plate. The enzyme was prepared in accordance with Journal of Biological Chemistry, 2001, Vol. 276, p. 21343-21350. The reaction was carried out by adding a test compound at various concentrations to a reaction liquid consisting of a 5 mM phosphate buffer (pH 6.6), 200 nM cortisone, 40 μM reduced nicotinamide adenine dinucleotide phosphate (NADPH), and rat recombinant 11β-HSD1, followed by incubating at room temperature for one hour (10 μl/well). The test compound was prepared by dissolving in dimethyl sulfoxide (DMSO) such that a DMSO concentration reached 1% in the reaction liquid. After the enzyme reaction was completed, the enzyme inhibitory action was measured by detecting cortisol using a homogeneous time-resolved fluorescence (HTRF) method. Each of a d2-labeled cortisol containing 400 μM carbenoxolone and a cryptate-labeled cortisol antibody (CIS Bio International Co., Ltd.) was added at 5 μl/well, followed by incubating at room temperature for 2 hours, and then the fluorescence intensity was measured using a fluorophotometer (trade name: ARVO HTS 1420, Perkin Elmer/Wallac), and the enzyme inhibitory activity was calculated from the fluorescence intensity ratio of two wavelengths (665 nm/620 nm).The measurement results were calculated by averaging the values of 3 wells of the same condition. The ratio when DMSO was added instead of the test compound was taken as 0% and the ratio when 11β-HSD1 was not added was taken as 100%, thereby calculating the 50% inhibition concentration of the test compound as IC50 of the compound inhibitory activity.

The reaction was terminated by the addition of 100 μl of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm. IC50 values for compound inhibition were calculated directly from graphs of optical density (arbitrary units) versus compound concentration following subtraction of blank values.

Assay: MAP4K4 Inhibition Assay: The kinase activity of purified human MAP4K4 kinase domain was measured by monitoring the phosphorylation of a peptide substrate derived from moesin protein (Leu-Gly-Arg-Asp-Lys-Tyr-Lys-Thr-Leu-Arg-Gln-Ile-Arg-Gln) fluorescently labeled on the N-terminus with 5-carboxyfluorescein using the Caliper LabChip technology (Caliper Life Sciences, Hopkinton, Mass.). To determine inhibition constants (IC50), compounds were serially diluted in DMSO and added to 10 uL kinase reactions containing 1 nM purified MAP4K4 enzyme, 1 uM peptide substrate, 10 uM ATP, 10 mM MgCl2, 1 mM EGTA, 50 mM Hepes pH 7.2, 1 mM DTT, 0.01% Triton X-100, and 2% DMSO. Reactions were incubated at room temperature in Perkin Elmer Proxiplates for 45 minutes and stopped by the addition of 10 uL of an EDTA-containing solution (50 mM Hepes pH 7.2, 40 mM EDTA, 0.02% Triton X-100). The fraction of phosphorylated peptide was determined as a fraction of total peptide substrate using the Caliper Lab Chip 3000 according to the manufacturer's instructions. IC50 values were determined using the four-parameter non-linear fit model.

Assay: ThermoFluor Assay: ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Development, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation. Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1° C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature.
