UniProt: Q9BZP6
Assay: Human AMCase Activity Assay: An enzymatic assay with recombinant human AMCase was used in order to establish inhibitory activity of the compounds (Boot et al., 2001, JBC: 276). The assay was run in the 96-well plate format, each reaction in the total volume of 100 μL. 4-Methylumbelliferyl B-D-N,N′-diacetylchitobioside hydrate was used as a substrate for the enzyme. Upon hydrolysis by AMCase, the substrate releases 4-methylumbelliferyl (4MU) that, when ionized in basic pH, emits fluorescence at 460 nm.Briefly, 40 μL of a substrate was added to each well, followed by 10 μL of compound dilution and 50 μL of hAMCase recombinant enzyme solution. The reaction was carried out in citrate buffer, pH 5.2, in the dark, at 37° C. for 60 minutes with shaking. After that time the reaction was stopped by adding 195 μL of Stop Buffer (pH 10.5) to each well. The fluorescence of the reaction product was measured in Perkin Elmer Envision fluorescent plate reader at an excitation wavelength of 355 nm. The IC50 values were calculated using GraphPad Prism.

Assay: HTRF 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 uL of 1.11x enzyme and 1.11x substrate in 1x 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 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: Enzyme Inhibition Assay: Measurements were performed using a modification of the scintillation proximity assay platform described previously by Georgopapadakou, N. H. et al. (22nd International Congress on Chemotherapy, 2001, Abstract P16.001). Compounds were solubilised in DMSO at a top concentration of 10 mM and serially diluted in half log steps to achieve a range of final assay concentrations of 100 uM to 1 nM. Compound at each concentration (100-fold final) was added to white 384 well plates in a volume of 0.5 ml. Human, A. fumigatus, T. brucei or L. major N-myristoyl transferase enzyme, dissolved to a working concentration of 10 nM in assay buffer (30 mM Tris/HCl pH 7.4, 0.5 mM EGTA, 0.5 mM EDTA, 1.25 mM DTT, 0.1% Triton X-100), was then added to columns 1 to 11 and 13 to 23 of the plates in a volume of 20 ml. To columns 12 and 24, 20 ml assay buffer was added to provide a no enzyme control. Following a 5 minute incubation at room temperature the substrates (GCGGSKVKPQPPQAK(Biotin)-Amide and myristoyl coenzyme A), dissolved in assay buffer, were added to all wells in a volume of 20 ml to start the reaction. The final concentrations of peptide and 3H-myristoyl coenzyme A were 0.5 mM and 125 nM respectively and the specific activity of the radiolabel was 8 Ci/mmol. Plates were then incubated at room temperature for up to 50 minutes (dependant upon the period of linearity for the different enzyme species) before SPA beads, suspended to 1 mg/ml in a stop solution (200 mM Phosphoric Acid/NaOH pH 4, 750 mM MgCl2), were added in a volume of 40 ml.

Assay: Time Resolved Fluorescence Resonance Energy Transfer (TR-FRET)-Based cAMP Immunoassay: Mouse R1.G1 cells (ATCC, Manassas, Va.) were grown in suspension in high glucose-DMEM (Dulbecco's Modified Eagle's Medium, Cellgro, Herndon, Va.) containing 10% horse serum and 2% glutaMax (Invitrogen, Carlsbad. Calif.) without added antibiotics. On the day of the experiment, cells were spun at 1,000 rpm for 5 minutes at room temperature and then washed once with HBSS (HEPES Buffered Saline Solution, Invitrogen, Carlsbad, Calif.). Cells were then spun again and resuspended in stimulation buffer (HBSS with 0.05% FAF-BSA (Fatty acid-free bovine serum albumin, Roche Applied Science, Indianapolis, Ind.), 5 mM HEPES) to 2 million cells per ml. Antibody supplied with the LANCE™ cAMP immunoassay kit was then added to the cells according to the manufacturer's instructions, and 12,000 cells per well were then added to the wells containing forskolin to a predetermined fixed final concentration (typically about 2.5 μM) and the previously determined amount of the synthetic peptide amide to be tested. The synthetic peptide amides were tested in a range of concentrations to determine potency. Cells were incubated with the synthetic peptide amide plus forskolin for about 20 minutes at room temperature. After incubation, cells are lysed by adding 12 μl of detection mix as supplied with the LANCE™ kit, followed by incubation for one hour at room temperature. Time resolved fluorescence was read using a 330-380 nm excitation filter, a 665 nm emission filter, dichroic mirror 380, and Z=1 mm.

Assay: ERK2 (20 pM) Kinase Assay: Compound potency against activated ERK2 was determined using a kinase assay that measures ERK2-catalyzed phosphorylation of biotinylated ERKtide peptide substrate ([Biotin]-AHA-K-R-E-L-V-E-P-L-T-P-S-G-E-A-P-N-Q-A-L-L-R-[NH2], the peptide sequence derived from EGF receptor: SEQ ID NO:1). The assay was carried out in 20 mM HEPES [pH 7.5], 5 mM MgCl2, 1 mM DTT, 0.01% Tween-20, 0.05% BSA using 0.02 nM ERK2, 400 nM ERKtide peptide and 35 uM ATP (all concentrations are final in the reaction) in a total volume of 10.25 uL. A 16-point, half-log dilution series of compounds at 41x final concentration was used for generating IC50 curves. Compound dilution series were prepared in 100% DMSO. ERK2 was preincubated with compounds for 30 minutes at ambient temperature. Reaction was initiated by addition of a substrate cocktail of ERKtide peptide and ATP and was allowed to proceed for 4 hours at ambient temperature. Reaction was terminated by addition of 10 uL of a 2x stop buffer consisting of 100 mM Tris-Cl [pH 7.5], 25 mM EDTA, 0.01% Tween 20, 20 ug/mL of AlphaScreen Protein A Acceptor Beads, 20 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1:1000 dilution phospho-EGF Receptor (Thr669) antibody (Cat #8808, Cell Signaling Technology, Danvers, Mass.). Terminated reactions were read, after overnight incubation in the dark, on an EnVision Multilabel Plate Reader (PerkinElmer, Waltham, Mass.), with excitation and emission wavelengths set to 680 nm and 570 nm, respectively. IC50 values were determined using a four-parameter fit.

Cells were released from culture flasks using trypsin/EDTA, harvested, washed twice with ice-cold PBS (without Ca2+ and Mg2+), pelleted at 1'000 rpm for 5 min at 4Â° C., frozen and stored at â¿¿80Â° C. Frozen pellets were suspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 10 mM EDTA and homogenized with a Polytron (PT 6000, Kinematica) at 14'000 rpm for 20 s. The homogenate was centrifuged at 48'000Ã¿g for 30 min at 4Â° C. Subsequently, the supernatant was removed and discarded, and the pellet resuspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 0.1 mM EDTA using the Polytron (20 s at 14'000 rpm). This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at â¿¿80Â° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 Î¼M unlabeled ligand. All compounds were tested at a broad range of concentrations (10 Î¼M to 10 Î¼M) in duplicates. The test compounds (20 Î¼l/well) were transferred into a 96 deep well plate (TreffLab), and 180 Î¼l of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 Î¼l of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3Ã¿Kd in nM and 500 Î¼l of the membranes (resuspended at 50 Î¼g protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4Â° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer.

Assay: Radioligand Binding (rat TAAR1): HEK-293 cells stably expressing rat TAAR1 were maintained at 37Â° C. and 5% CO2 in DMEM high glucose medium, containing fetal calf serum (10%, heat inactivated for 30 min at 56Â° C.), penicillin/streptomycin (1%), and 375 Î¼g/ml geneticin (Gibco). Cells were released from culture flasks using trypsin/EDTA, harvested, washed twice with ice-cold PBS (without Ca2+ and Mg2+), pelleted at 1'000 rpm for 5 min at 4Â° C., frozen and stored at â¿¿80Â° C. Frozen pellets were suspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 10 mM EDTA and homogenized with a Polytron (PT 6000, Kinematica) at 14'000 rpm for 20 s. The homogenate was centrifuged at 48'000Ã¿g for 30 min at 4Â° C. Subsequently, the supernatant was removed and discarded, and the pellet resuspended in 20 ml HEPES-NaOH (20 mM, pH 7.4) containing 0.1 mM EDTA using the Polytron (20 s at 14'000 rpm). This procedure was repeated and the final pellet resuspended in HEPES-NaOH containing 0.1 mM EDTA and homogenized using the Polytron. Typically, aliquots of 2 ml membrane portions were stored at â¿¿80Â° C. With each new membrane batch the dissociation constant (Kd) was determined via a saturation curve. The TAAR1 radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine (described in WO 2008/098857) was used at a concentration equal to the calculated Kd value, that was usually around 2.3 nM, resulting in the binding of approximately 0.2% of the radioligand and a specific binding representing approximately 85% of the total binding. Nonspecific binding was defined as the amount of 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine bound in the presence of 10 Î¼M unlabeled ligand. All compounds were tested at a broad range of concentrations (10 Î¼M to 10 Î¼M) in duplicates. The test compounds (20 Î¼l/well) were transferred into a 96 deep well plate (TreffLab), and 180 Î¼l of HEPES-NaOH (20 mM, pH 7.4) containing MgCl2 (10 mM) and CaCl2 (2 mM) (binding buffer), 300 Î¼l of the radioligand 3[H]â¿¿(S)-4-[(ethyl-phenyl-amino)-methyl]-4,5-dihydro-oxazol-2-ylamine at a concentration of 3.3Ã¿Kd in nM and 500 Î¼l of the membranes (resuspended at 50 Î¼g protein per ml) added. The 96 deep well plates were incubated for 1 hr at 4Â° C. Incubations were terminated by rapid filtration through Unifilter-96 plates (Packard Instrument Company) and glass filters GF/C (Perkin Elmer) presoaked for 1 hr in polyethylenimine (0.3%) and washed 3 times with 1 ml of cold binding buffer. After addition of 45 Î¼l of Microscint 40 (PerkinElmer) the Unifilter-96 plate was sealed and after 1 hr the ratioactivity counted using a TopCount Microplate Scintillation Counter (Packard Instrument Company).
