Target: Tyrosine-protein kinase SYK (SINGLE PROTEIN), Homo sapiens
UniProt: P43405
Assay: Homogeneous Time-Resolved Fluorescence (HTRF) Assay: A recombinant GST-hSYK fusion protein was used to measure potency of compounds to inhibit human Syk activity. The recombinant human GST-SYK (Carna Biosciences #08-176) (5 μM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for Syk was added with magnesium (5 mM final concentration) and ATP (25 μM final concentration). Final volume of the reaction was 10 μL. Phosphorylation of the peptide was allowed to proceed for 45' at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #AD0161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5, 40 mM EDTA, 0.01% tween 20. Final volume of the quenching solution was 10 μL. The resulting HTRF signal was measured after 30 minutes on an EnVision (Perkin-Elmer) reader using a time-resolved fluorescence protocol.

Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens
UniProt: P49327
Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
UniProt: Q06187
Assay: LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) Assay: BTK enzymatic activity was determined with the LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) assay. In this assay, the potency (IC50) of each compound was determined from an eleven point (1:3 serial dilution; final compound concentration range in assay from 1 uM to 0.017 nM) titration curve using the following outlined procedure. To each well of a black non-binding surface Corning 384-well microplate (Corning Catalog #3820), 5 nL of compound (2000 fold dilution in final assay volume of 10 uL) was dispensed, followed by the addition of 7.5 uL of 1x kinase buffer (50 mM Hepes 7.5, 10 mM MgCl2, 0.01% Brij-35, 1 mM EGTA, 0.05% BSA & 1 mM DTT) containing 5.09 pg/uL (66.67 pM) of BTK enzyme (recombinant protein from baculovirus-transfected Sf9 cells: full-length BTK, 6HIS-tag cleaved). Following a 60 minute compound & enzyme incubation, each reaction was initiated by the addition of 2.5 uL 1x kinase buffer containing 8 uM biotinylated "A5" peptide (Biotin-EQEDEPEGDYFEWLE-NH2) (SEQ ID NO: 1), and 100 uM ATP. The final reaction in each well of 10 uL consists of 100 pM hBTK, 2 uM biotin-A5-peptide, and 25 uM ATP. Phosphorylation reactions were allowed to proceed for 120 minutes. Reactions were immediately quenched by the addition of 20 uL of 1x quench buffer (15 mM EDTA, 25 mM Hepes 7.3, and 0.1% Triton X-100) containing detection reagents (0.626 nM of LANCE-Eu-W1024-anti-phosphoTyrosine antibody, PerkinElmer and 86.8 nM of Streptavidin-conjugated Dylight 650, Dyomics/ThermoFisher Scientific). After 60 minutes incubation with detection reagents, reaction plates were read on a PerkinElmer EnVision plate reader using standard TR-FRET protocol. Briefly, excitation of donor molecules (Eu-chelate:anti-phospho-antibody) with a laser light source at 337 nm produces energy that can be transferred to Dylight-650 acceptor molecules if this donor:acceptor pair is within close proximity. Fluorescence intensity at both 665 nm (acceptor) and 615 nm (donor) are measured and a TR-FRET ratio calculated for each well (acceptor intensity/donor intensity). IC50 values were determined by 4 parameter robust fit of TR-FRET ratio values vs. (Log10) compound concentrations.

Assay: Kinase Assay: For the assay 50 nL of a 100-fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 μl of a solution of Mps-1 in assay buffer [0.1 mM sodium-ortho-vanadate, 10 mM MgCl2, 2 mM DTT, 25 mM Hepes pH 7.7, 0.05% BSA, 0.001% Pluronic F-127] were added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to Mps-1 before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 μl of a solution of 16.7 adenosine-tri-phosphate (ATP, 16.7 μM=>final conc. in the 5 μl assay volume is 10 μM) and peptide substrate (1.67 μM=>final conc. in the 5 μl assay volume is 1 μM) in assay buffer and the resulting mixture was incubated for a reaction time of 60 min at 22° C. The concentration of Mps-1 in the assay was adjusted to the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical enzyme concentrations were in the range of about 1 nM (final conc. in the 5 μl assay volume). The reaction was stopped by the addition of 3 μl of a solution of HTRF detection reagents (100 mM Hepes pH 7.4, 0.1% BSA, 40 mM EDTA, 140 nM Streptavidin-XLent [#61GSTXLB, Fa. Cis Biointernational, Marcoule, France], 1.5 nM anti-phospho(Ser/Thr)-Europium-antibody [#AD0180, Perkin Elmer LAS, Rodgau-Jügesheinn, Germany]. The resulting mixture was incubated 1 h at 22° C. to allow the binding of the phosphorylated peptide to the anti-phospho(Ser/Thr)-Europium-antibody. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Europium-labelled anti-phospho(Ser/Thr) antibody to the Streptavidin-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a Viewlux TR-FRET reader (PerkinElmer LAS, Rodgau-Jügesheinn, Germany).

Assay: Cell Based Assay: TRKA co-expressed with p75: The assays are based upon DiscoveRx's proprietary Enzyme Fragment Complementation (EFC) technology. In the case of the TRK cell lines, the enzyme acceptor (EA) protein is fused to a SH2 protein and the TRK receptor of interest has been tagged with a Prolink tag. Cryopreserved PathHunter cells are used from either in-house produced batches or bulk batches bought directly from DiscoveRx. Cryopreserved cells are resuscitated, spun 1000 rpm for 4 min to remove freezing media, and resuspended in MEM+0.5% horse serum (both Invitrogen) to 5e^5 cells/ml. The cells are then plated using a Multidrop into Greiner white tissue culture treated plates at 20 μl/well and incubated for 24 h at 37 °C., 5% CO2, high humidity. On the day of the assay, the cell plates are allowed to cool to room temperature for 30 min prior to the assay. 4 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

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 MCAGKPILFFRLK(Dnp)d-R-NH2 (Enzo Life Sciences, Lorrach). 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 ul of each substance solution with serially diluted substance concentration were added to in each case 4 ul of cathepsin D solution and incubated at room temperature for 10 min. The reaction was started by addition of 2 ul of substrate solution (final concentration 5 uM). 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).

After equilibration, 2 uL of 10xATP in 1x 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 uL of 2x 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.

Assay: LCMS Assay: The MGAT enzyme reactions were performed in Corning FALCON® 96-well Polypropylene plates, in a total volume of 60 μL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 μM 2-oleoylglycerol, 15 μM oleoyl-Coenzyme A and 0.0013 μg/μL Human or Mouse MGAT-2 or 0.0026 μg/μL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 μL of ice cold methanol containing 1 μg/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50×2.1 mm column, was used for the chromatography of enzyme products. The buffer system consists of 0.1% formic acid in water with a mobile phase consisting 0.1% formic acid in methanol. The shallow gradient is 90-100% mobile phase in 0.2 min with a total run time of 2.3 min. The first 0.5 minutes of each injection was diverted to waste to eliminate the presence of Phosphate buffer in the enzymatic reaction. The column was run at 0.6 mL/min and a temperature of 65° C.
