Target: Endothelial lipase (SINGLE PROTEIN), Homo sapiens
UniProt: Q9Y5X9
Assay: Enzymatic Assay: Endothelial lipase activity was measured using a fluorescent substrate, A10070, (Invitrogen, CA) doped into an artificial vesicle containing DMPG (Avanti Polar Lipids) as the excipient. Vesicles were prepared by combining 285 uL of 1 mMDMPG in a 1:1 mixture of MeOH and CHCl3 with 15 uL of 1 mM A10070 in a 1:1 mixture of MeOH and CHCl3. The mixture was dried under nitrogen and resuspended in 150 uL of 50 mM HEPES pH 8.0 buffer containing 100 mM NaCl and 0.2 mM EDTA. The sample was allowed to sit at rt for 15 min and then was sonicated 3x4 mins on ice with a Branson Sonicator using duty cycle 1. This preparation provides vesicles with a mole fraction of 0.05 for the FRET substrate.The enzymatic assay was measured using white, opaque 96-well half area plates. Each well contained 60 uL of assay buffer (50 mM HEPES pH 8.0, 50 mM NaCl and 1 mM CaCl2) and 2 ul of a DMSO solution containing compound of interest. Conditioned media obtained from HT-1080 cells, which were transformed by RAGE technology (Athersys) to overexpress endogenous EL, was added and the reaction was allowed to incubate for 20 min at 37deg; C. with gentle agitation. The reaction was started by the addition of 20 uL of a 1:4 dilution of vesicles. The final total reaction volume was 100 uL. The reaction rates were measured on a Gemini plate reader with an excitation wavelength of 488 nm and a emission of 530 nm. Readings were taken every 20 seconds for 10 min with agitation between each reading. The slope of the linear portion of the readout was used to calculate the rate of the reaction.

UniProt: Q1A7N1
Assay: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.

Assay: Enzyme Inhibition Assay: For enzymology studies of these compounds, recombinant guinea pig liver TGase was expressed in Escherichia coli and effectively purified (Gillet, S. M. F. G. et al J. N., Prot. Exp. & Purif. 2004, 33, 256). In addition to being easy to obtain in excellent yield and solubility, guinea pig liver TGase was chosen because it shows 80% homology with human tissue TGase (Aeschlimann, D.; Paulsson, M., Throm. Haemost. 1994, 71, 402) and may thus serve as a model for the evaluation of inhibitors of potential therapeutic utility.The IC50 values of synthetic analogues 14a-38a were determined from inhibition of the reaction of 54.4 mM of the chromogenic TGase substrate N-Cbz-Glu(Î³-p-nitrophenyl ester)Gly with 0.010 U of recombinant guinea pig liver TGase as previously reported (Leblanc, A.; Gravel, C.; Labelle, J.; Keillor, J. W. Biochemistry 2001, 40, 8335) and described in detail in the Materials section below. The mode of inhibition was determined for the representative lead compound.

Assay: ThermoFluor® Assay: 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. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1×=46 nL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

Assay: Eis inhibition assay: To investigate the potential of these compounds as Eis inhibitors for use in combination with KAN, their biochemical (IC50 values against purified Eis enzyme) and biological (effect on the MIC values of KAN in KAN-sensitive Mtb H37Rv and in Mtb K204, which is KAN-resistant due to Eis upregulation properties were evaluated in parallel studies (Table 2 and FIG. 1). The freshly synthesized compound 29 displayed robust inhibition of Eis in vitro (IC50=0.08±0.02 μM). When combined with KAN, sulfonamide 29, resulted in a four-fold reduced KAN MIC value (2.5 μg/mL) compared to KAN alone (10 μg/mL) for K204 Mtb. This was a reduction almost to the MIC level of KAN in the KAN-susceptible Mtb H37Rv (1.25 μg/mL) parent strain. To gain insight into the importance of the substitution pattern on the aniline portion of the sulfonamide scaffold, secondary (NHAr) and tertiary (N(Me)Ar) sulfonamides (29-47) were first generated. Eis inhibition assays with the synthesized sulfonamides were carried out in combination with KAN. The non-methylated counterpart of lead compound 29, compound 30, displayed lower Eis inhibitory activity (IC50=6.24±1.31 μM) and, contrary to 29, did not overcome KAN resistance in Mtb K204 (MICKAN=10 μg/mL). Two other non-methylated derivatives, 31 and 32, also resulted in lower Eis inhibitory activity (IC50>200 and 10.6±2.5 μM, respectively) and did not overcome KAN resistance in Mtb K204 (MICKAN=10 and 5 μg/mL, respectively).

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: Radioligand Binding Assay: The composition of the binding assay buffer is determined in a course of detailed optimization procedure. This resulted in a binding assay buffer constituted by the following components: 25 mM Hepes (pH=7.4), 5 mM MgCl2, 1 mM CaCl2, 100 mM NaCl, supplemented with 0.1% of protease free BSA (as a final concentration). Competition binding assay is performed using 125I-CXCL10 (PerkinElmer, NEX348, specific activity 2200 Ci/mmol) radioligand in a final concentration of 50-70 pM. The nonspecific binding is defined by 150 pM of hr-CXCL10 (R&D Systems, Cat No 266-IP). The total assay volume is equal to 150 ul and contained 1% of DMSO (final concentration). Binding reaction is initiated by adding of membranes (10-20 ug proteins, approximately 5x105 cell equivalents) to the reaction mixture. After 60 minutes of incubation at 25° C. the reaction is terminated by rapid filtration over GF/B glass fibre filters that are pre-soaked with 0.5% polyethyleneimine (Fluka Analytical, P3143) for 1 hour, using a Skatron cell harvester device. Filters then are washed with 8 ml of ice-cold wash buffer (modified binding buffer in which BSA is omitted and the concentration of NaCl is adjusted to 500 mM concentration). The radioactivity retained on the filters is measured by a Wizard 1470 Automatic Gamma counter.

Assay: Radioligand Binding Assay: Assessments of compound binding to human MC5R (hMC5R)) by displacement of an 125I-labeled NDP-MSH receptor ligand peptide were performed essentially as described in the data sheets produced by Perkin Elmer to accompany their frozen hMC5R membranes (Perkin Elmer catalog number RBXMC5M400UA). [125I] NDP-MSH: Radiolabeled in House and Purified by HPLC: Na125I (0.5 mCi, 17.4 Ci/mg) was added to 50 μL sodium phosphate (50 mM, pH 7.4) in an eppendorf tube precoated with IODOGEN. After incubation for 10 mins the phosphate buffer containing the iodine was added to NDP-MSH (10 μl at 1 mg/mL) in a separate eppendorf tube. This was incubated for a further 10 mins. The iodinated NDP-MSH was purified by HPLC on a Zorbax SB 300 column using solvent A: 0.05% TFA and solvent B: 90% acetonitrile 0.045% TFA with a linear gradient, 0-67% B over 60 mins. The 125I NDP-MSH eluted at 52 mins after the unlabeled starting material (48 min) and was counted and stored in the freezer. It was used within 48 hrs, as radioactive decay and ligand decomposition resulted in greatly reduced specific binding observed after 72 hrs. Incubation buffer: 25 mM HEPES-KOH (pH 7.0), 1.5 mM CaCl2, 1 mM MgSO4, 0.1 M NaCl, 1 mM 1,10-phenanthroline, and 1 Complete™ protease inhibitor tablet/100 mL (Roche, catalog number 1873580). Perkin Elmer frozen hMC5 membranes: catalog number RBXMC5M400UA, 0.4 mL/vial; 400 microassays/vial, 0.78 mg/mL protein concentration. Vials of frozen membranes were thawed rapidly immediately before use, diluted with binding buffer and vortexed. Resuspended membranes were kept on ice until they were added to the wells of the plate. Assays were performed in 96 well polypropylene plates. Membranes (0.78 μg 40 μL of a 1:40 dilution in incubation buffer) were added to [125I] NDP-MSH (0.84 nM; 2200 Ci/mmol) and test compounds in a total volume of 140 μL. This was incubated for 1 hr at 37° C. Non-specific binding was determined with 3 mM NDP-MSH. Plates were filtered using a Tomtec cell harvester with GF/A filters (Wallac) (presoaked in 0.6% polyethylenimine) and washed three times with 1.0 mL ice-cold wash buffer (the above incubation buffer without 1,10-phenanthroline and Complete™ protease inhibitor tablet). The filters were dried in a 37° C. oven, placed in a sample bag and 5 mL Betaplatescint (Wallac) was added. Prepared filters were counted in cassettes in a Microbeta Trilux (Wallac) for 1 min.

Assay: Scintillation Proximity Assay (SPA): A SPA membrane binding assay was used to identify inhibitors of [33P] 2MeS-ADP binding to cloned human P2Y1 receptors (The P2Y1 receptor membranes were provided by Biology and the cloning of the receptor and P2Y1 receptor membrane preparation is same as described by Biology). Binding reactions were performed in 384-well OptiPlates (PerkinElmer Life Sciences, Cat #6007299) in a volume of 50 uL containing 15 fmol of P2Y1 receptor (1.7 ug of total protein), 0.3 nM [33P] 2MeS-ADP (PerkinElmer; 2,000 Ci/mmol), various concentrations of the test compound (usually between 10 uM and 160 pM) in Buffer B containing 1% DMSO in assay buffer (15 mM, HEPES, 145 mM potassium chloride, 5 mM sodium Chloride, 5 mM EDTA, 0.1 mM MgCl2, pH 7.4) and 100 ug of SPA bead (WGA polystyrene Image beads, #RPNQ 0260V, Amersham). Reactions were allowed to proceed to completion at room temperature for 1 hour followed by centrifugation of the plate for 5 min. About 40 uL of the aqueous soluttion was aspirated. Plates were sealed and the [33P] 2MeS-ADP bound to the P2Y1 receptor membranes that were bound to the SPA bead were determined in a Gen 4 LEADSEEKERSM (Amersham) Image Reader. Dose-response curves (IC50) were fit by non-linear regression (Toolset an in house data processing program) and binding constants (Ki) calculated using the Cheng-Prusoff relationship (Ki=IC50/(1+L/Kd) in which a Kd for 2MeS-ADP to the P2Y1 receptor was determined to be 14 nM.

Assay: Inhibition Assay: mPGES-1 microsome fractions were prepared from CHO-K1 cells transiently transfected with plasmid encoding the human mPGES-1cDNA. Microsomes were diluted with potassium phosphate buffer containing reduced glutathione (pH7.4), and DMSO containing test compound or DMSO alone was added (such that DMSO final concentration would be 1% in each) and incubated at 4° C. for 20 minutes. Then, the enzymatic reactions were initiated by the addition of PGH2 substrate (final concentration 1 μM) and incubated at 4° C. for 60 seconds. The reaction was terminated by the addition of a citrate solution (final citrate concentration 50 mM) containing ferric chloride (final concentration 1 mg/mL). PGE2 production in the enzyme reaction aliquot was measured using HTRF kit (Cisbio International, catalogue #62P2APEC).

Assay: P70S6K Enzyme Assay: P70S6K inhibitor compounds are diluted and plated in 96 well plates. A reaction mixture including the following components is then added to the compound plate to initiate the enzyme reaction; P70S6K (3 nM, T412E mutant, Millipore) is mixed with 24 uM ATP in an assay buffer containing 100 mM Hepes (pH 7.5), 5 mM MgCl2, 1 mM DTT, 0.015% Brij and 1 uM of the substrate peptide FITC-AHA-AKRRRLSSLRA-OH (derived from the S6 ribosomal protein sequence, FITC=fluorescein isothiocyanate, AHA=6-aminohexanoic acid). The reaction is incubated for 90 min at 25.degree. C., before the addition of 10 mM EDTA to stop the reaction. The proportion of substrate and product (phosphorylated) peptide is analysed on a Caliper Life Sciences Lab Chip 3000, using a pressure of -1.4 psi, and upstream and downstream voltages of -3000 and -700 respectively. Product peaks are resolved before substrate peaks on the resulting chromatograms.
