UniProt: O75874
Assay: Enzymatic Assay: Each test compound (10 mM stock in DMSO) is diluted in DMSO to make a 10-point, 3-fold dilution series. 125 nL of each dilution or DMSO alone is dispensed to a 384-well Greiner Lumitrac 200 assay plate using an Echo® Liquid Handler. To each well of the plate is added 20 uL of enzyme in assay buffer or assay buffer alone. Assay buffer consists of 50 mM sodium phosphate, pH 7.0, 50 mM magnesium chloride, 50 mM sodium chloride, and 0.01% (w/v) bovine serum albumin. When present, the R132H mutant IDH1 enzyme is at a working concentration of 1.875 nM (final concentration in assay of 1.5 nM). The assay plate is allowed to incubate for 30 minutes at room temperature and 5 uL of 5× substrate mixture (2.5 uM nicotinamide adenine dinucleotide phosphate, 100 uM adenosine diphosphate, 7.5 mM glyceraldehyde-3-phosphate, 7.5 ug/mL of spinach glyceraldehyde-3-phosphate dehydrogenase, 25 nM phosphoglycerate kinase, and 5 mM alpha-ketoglutarate in assay buffer) is added to all wells. The reaction plate is incubated for 60 minutes followed by addition of 25 uL of Promega Kinase-GLO reagent to all wells and 10-minute incubation.Luminescence is measured using a PerkinElmer Envision plate reader. The percent activity of each dilution is determined as the ratio of background corrected signal to the background corrected signal of wells receiving only DMSO. IC50 values are determined by fitting percent activity data to a four-parameter logistic dose response equation.

Assay: Biochemical Assay for LSD1 Activity (15 minutes): LSD1 demethylase reactions were carried out in 50 mM HEPES pH 7.4, 100 mM NaCl, 1 mM DTT, 0.01% Tween-20, and 0.1 mg/mL BSA. All enzymatic reactions were performed for either 15 minutes at room temperature in a 10-μL volume. Five microliters of 800 nM biotinylated H3K4me1 peptide solution was added to each well of a black 384 well Proxiplate containing 80 nL compound (final concentration of 0.8% DMSO). Reactions were initiated by the addition of a mixture containing 20 nM LSD1 and 20 nM FAD (5 μL). Enzyme activity was stopped by the addition of 5 μL of high salt buffer consisting of 50 mM HEPES pH 7.4, 1.5 M NaCl, 1 mM DTT, 0.01% Tween-20, and 0.1 mg/mL BSA. Capture of the product peptide by the anti-H3K4me0 antibody and Streptavidin APC was allowed to proceed for 60 mM at room temperature before measuring the TR-FRET signal. Europium-labeled antibody and Streptavidin APC were used at final concentrations of 0.003 nM and 100 nM, respectively (total assay volume of 20 μL). Plates were read on a Perkin Elmer EnVision. Percent inhibition was calculated using Max (no inhibitor) and Min (quenched with stop buffer) controls and inhibition curves plotted to determine IC50 values.

Assay: HBsAg Assay: HepG2.2.15 cells were seeded in duplicate into white, 96-well plates at 1.5×104 cells/well. The cells were treated with a three-fold serial dilution series of the compounds in DMSO. The final DMSO concentration in all wells was 1% and DMSO was used as no drug control.The HBsAg chemiluminescence immunoassay (CLIA) kit (Autobio Diagnostics Co., Zhengzhou, China, Catalog number: CL0310-2) was used to measure the levels of secreted HBV antigens semi-quantitatively. For the detection 50 μL/well culture supernatant was used and HBsAg was quantified using HBsAg chemiluminescence immunoassay (CLIA) kit (Autobio Diagnostics Co., Zhengzhou, China, Catalog number: CL0310-2), 50 μL of the supernatant was transferred to the CLIA assay plate and 50 μL of enzyme conjugate reagent was added into each well. The plates were sealed and gently agitated for 1 hour at room temperature. The supernatant-enzyme-mixture was discarded and wells were washed 6 times with 300 μL of PBS. The residual liquid was removed by plating the CLIA plate right side down on absorbent tissue paper. 25 μL of substrates A and B were added to each well. Luminance was measured using a luminometer (Mithras LB 940 Multimode Microplate Reader) after 10 minutes incubation. Dose-response curves were generated and the IC50 value was extrapolated by using the E-WorkBook Suite (ID Business Solutions Ltd., Guildford, UK). The IC50 was defined as the compound concentration (or conditioned media log dilution) at which HBsAg secretion was reduced by 50% compared to the no drug control.

Assay: Inhibition Assay: The IC50 values for the PHD2 enzyme (residues 181-417) were determined by mixing increasing amounts of inhibitor with a fixed amount of enzyme (5 nM, final concentration) and Biotin labeled peptide (Biotin-Asp-Leu-Glu-Met-Leu-Ala-Pro-Tyr-Ile-Pro-Met-Asp-Asp-Asp-Phe-Gln-Leu, 1 uM final concentration) and 2-Oxyglutarate (2 uM final concentration) in 50 mM HEPES, 50 mM KCl, 0.5 mM TCEP, 2 uM FeCl2, 0.1 mg/ml BSA, at pH 7.3. The reaction was conducted by pre-incubating the enzyme in the presence of inhibitor for 60 min at room temperature. The activity of the free enzyme was measured by adding the peptide, the 2-Oxoglutarate (see above for final concentrations), and Ascorbic Acid (1 mM final concentration). The enzymatic activity was quenched after 60 min by adding an excess of a tight binding inhibitor to the assay mixture. The amount of product released was measured by using a LC/MS system (Agilent HPLC with Applied Biosystems API3000 Mass Spectrometer).

Assay: RET Enzyme Assay: Compounds of General Formula I were screened for their ability to inhibit wild type and V804M mutant RET kinase using CisBio's HTRF® KinEASE -TK assay technology. Briefly, N-terminal GST tagged recombinant human RET cytoplasmic domain (aa 658-end) from Eurofins (0.25 nM RET; Cat. No. 14-570M) or N-terminal GST tagged recombinant human V804M mutant RET cytoplasmic domain (aa 658-end) from Millipore (0.25 nM enzyme; Cat. No. 14-760) was incubated with 250 nM TK-substrate biotin (CisBio, part of Cat. No. 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 in a threefold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 30-minute 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. No. 62TK0PEC). After a 1 hour 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. 100 POC was determined using no test compounds and 0 POC was determined using pre-quenched control reactions. The POC values were fit to a 4 parameter logistic curve, and the IC50 is defined as the concentration of inhibitor at which the POC equals 50 for the fitted curve.

UniProt: Q02083
Assay: Inhibition Assay: In order to have an assay method more conducive to high-throughput screening than those published for measuring the NAE hydrolyzing activity of NAAA, we developed the fluorogenic PEA analog N-(4-methyl coumarin)palmitamide (PAMCA), which is hydrolyzed to fluorescent 7-amino-4-methyl coumarin (AMC) and palmitic acid. For three point concentration inhibition assays with hNAAA the following procedure is used. Purified activated NAAA (final concentration of 0.25 μg/mL) is incubated in assay buffer (100 mM citrate-phosphate buffer, pH 4.5, 3 mM DTT, 0.1% Triton X-100, 0.05% BSA, and 150 mM NaCl) made up to a total volume of 180 μL, followed by addition of the compound dissolved in 10 μL DMSO (along with DMSO neat for the control sample) with the final concentrations for each compound of 100, 10, and 1 μM, in triplicate on a 96 well plate. These samples are allowed to incubate for 15 min at room temperature and then 10 μL of a PAMCA stock solution in DMSO (final PAMCA concentration [5 μM]) was added. After 5 minutes of agitation on a shaking plate, the reaction is allowed to proceed at 37° C. for 120 minutes, with fluorescence readings taken every 10 minutes at a wavelength of 460 nm (using an excitation wavelength of 360 nm) on a Synergy HT Plate Reader using Gen5 software from Bio-Tek. The enzyme activity is calculated by converting the relative fluorescence units to AMC formed, using a standard curve of AMC. For compounds that inhibit hNAAA in range IC50 <1 μM full inhibition curves using eight different concentrations of inhibitor (8 point assay) are generated. The assay procedure used is the same as the three point assay. For ostensibly covalent compounds (as observed by a significant decrease in the slope of a plot of fluorescence vs. time in three point screen) samples are allowed to incubate for 2 hours at 37° C., instead of 15 minutes, before addition of 10 μL of a PAMCA stock solution in DMSO for a final PAMCA concentration of 5 μM. After 5 minutes of agitation on a shaking plate, the reaction is allowed to proceed at 37° C. for 120 minutes Inhibition constants are calculated using pro Fit software (Quantum Soft, Uetikon am See, Switzerland) and a Levenberg-Marquardt algorithm.

Assay: LXR alpha/beta Radioligand Binding Assay: Compounds of the invention were assessed in a competition binding assay where different concentrations of compounds were incubated with the LXR ligand binding domain (LBD) in the presence of radiolabeled LXR ligand [3H]TO901317. The amount of the LXR-LBD that complexed with [3H]T0901317 was measured by scintillation proximity assay (SPA) employing non-specific binding of LXR-LBD to poly-lysine coated Yttrium silicate beads. Partially purified LXR α or β LBD protein (15-45 nM) was incubated at rt for 30 min with 15 nM [3H]TO901317 (25-40 Ci/mmol) and different concentrations of test compounds in 80 μL of phosphate buffered saline (PBS) buffer containing 2.5% DMSO, 1% glycerol, 2 mM EDTA, 2 mM CHAPS and 5 mM DTT in 96-well plates. Poly-lysine SPA beads (50 μg) were added to each well and the total volume was adjusted to 120 μL. The plates were shaken on an orbital shaker for 20 min and then allowed to settle for 10 more min at rt before a brief centrifugation at 2,000 rpm for 1 min. The SPA signal was measured on a MicroBeta® liquid scintillation counter (Perkin Elmer, Waltham, Mass.), and the results were used for calculating IC50 values based on the total binding (DMSO control) and non-specific binding (5 μM of unlabeled TO901317) controls. The Ki values were calculated according to equation 1, where [RL] is the final concentration of [3H]TO901317 in the assay, and the Kd values of 20 nM and 10 nM of TO901317 for LBDs of LXRα and LXRβ, respectively, were determined by direct titration of the radioligand with these proteins.

Assay: Biochemical Assay: Biochemical PDGFRβ kinase assays were performed in 96 well microtiter plates that were coated overnight with 75 μg of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.4. The coated plates were washed with 2 mls per well PBS+0.05% Tween-20 (PBS-T), blocked by incubation with PBS containing 1% BSA, then washed with 2 mls per well PBS-T prior to starting the reaction. Reactions were carried out in 100 μL reaction volumes containing 36 μM ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl2, 0.1 mM MnCl2 and 0.2 mM Na3VO4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 20 μl per well of kinase buffer containing 200-300 ng purified cytoplasmic domain PDGFR-b protein (Millipore). Following a 60 minute incubation at 30° C., the reactions were washed 2 mls per well PBS-T. 100 μl of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate diluted 1:10,000 in PBS-T was added to the wells for 30 minutes. Following a 2 mls per well wash with PBS-Tween-20, 100 μl of O-Phenylenediamine Dihydrochloride in phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7-10 minutes as a colorimetric substrate for the peroxidase. 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.

Assay: Jak Biochemical HTRF Assay Protocol: The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction. Plates were shaken and centrifuged and then incubated 60 minutes at room temperature and then read on a Perkin Elmer Envision (Xex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading. After normalization to untreated controls, the percent inhibition of the HTRF signal at each compound concentration was calculated. The plot of percent inhibition versus the log of compound concentration was fit with a 4-parameter dose response equation to calculate IC50 values.Final reaction conditions were:[E] [S] [ATP] [Eu-pY20] [SA-Dylight]Enzyme (nM) (μM) (μM) (nM) (nM)JAK1 1.405 0.75 31.8 9 312.5JAK2 0.052 0.75 8.5 9 312.5JAK3 0.031 0.75 2.9 9 312.5Tyk2 2.612 0.75 6.9 9 312.5Compound concentrations tested were 1496, 499, 175, 49.9, 18.7, 6.2, 2.1, 0.75, 0.24, 0.075, and 0.0125 nM, with 1.25% residual DMSO.

Assay: NAMPT Enzyme Assay: To measure the inhibition of NAMPT activity hNAMPT protein stock and anti 6His-Tb (Cisbio; Cat. No. 61HISTLB) is diluted to 3× final concentration with assay buffer (50 mM Tris-HCl (pH7.5), 1 mM DTT, 100 mM NaCl, 10 mM MgCl2, 0.005% Tween 20). 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.

Assay: Inhibition Assay: Various concentrations of test compounds were prepared in DMSO and then diluted into buffer consisting of 50 mM sodium phosphate 0.25% w/v sodium taurodexoycholate, pH 7.0. GCase enzyme (Cerezyme®, recombinant human GCase obtained from R&D Systems) was diluted in the same buffer to 0.143 nM. The reaction solution consisted of 25 μL of 6 mM 4-methylumbelliferone-β-D glucopyranoside in 10% DMSO in the same buffer, 12.5 μL of enzyme and 12.5 μL of various concentrations of test compound diluted in buffer. The final concentrations in the reaction were 0.036 nM GCase, 3 mM 4-methylumbelliferone-β-D glucopyranoside, and various concentrations of inhibitor. The reaction was initiated by addition of enzyme and allowed to proceed for 20 min at 37° C. to assess GCase activity. Reactions were stopped by the addition of an equal volume (50 μL) of 0.5 M NaOH, 0.3 M glycine, pH 10.5. Fluorescence was measured on a Biotek Synergy H4 plate reader using a setting of 10 measurements per data point at wavelengths of 365 nm for excitation and 450 nm for emission. Incubations without added enzyme or added inhibitors were used to define no enzyme activity and maximal enzyme activity, respectively. IC50 values were determined by fitting the data to a log [inhibitor concentration] versus response curve using GraphPad Prism. IC50 values were calculated as the concentration of inhibitor required to inhibit GCase activity by 50%. Ki values were determined from the IC50 values by employing the Cheng-Prusoff equation using a GCase Km of 7.9 mM for 4-methylumbelliferone-β-D glucopyranoside at pH 7.0.

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.

The standard pipette solution consisted of 140 mM CsAsp, 10 mM EGTA, 10 mM HEPES, 2.27 mM, 20 MgCl2, 1.91 mM CaCl2, and up to 0.3 mM Na2GTP, with pH adjusted to 7.2 with CsOH. In addition, a solution containing 145 mM CsCl, 10 mM HEPES, 10 mM EGTA, and up to 0.3 mM Na2GTP and 1 mM MgCl2 (pH 7.2 adjusted with CsOH) can be used. The standard bath solution contained 150 mM NaCl, 10 mM HEPES, 10 mM glucose, 4.5 mM KCl, 1 mM EGTA, 3 mM MgCl2, with pH adjusted to 7.4 with NaOH. In some instances, 2 mM CaCl2 was added in place of EGTA and the concentration of MgCl2 was reduced to 1 mM.Data were collected either by continuous recordings at −60 mV or by applying voltage ramps from a holding potential of −40 mV every 4 s. Continuous recordings were collected at 400 Hz and digitally filtered off-line at 10 Hz for presentation. Voltage ramps were applied from −100 mV or −80 mV to +100 mV or +80 mV over the course of 400 ms, and data were collected at 10 kHz and filtered at 2.9 kHz. Inward and outward currents were analyzed from the ramps at −80 and 80 mV, respectively. Liquid junction potential correction was not used.
