Assay: Cellular Assay: Assay b) HT29 cells (ECACC #85061109) were seeded into 384 well assay plates (Costar #3712) at a density of 6000 cells/well in 40 μl EMEM medium containing 1% L glutamine and 10% FBS and allowed to adhere overnight. The following morning compound of Formula (I) in 100% DMSO was added to assay plates by acoustic dispensing. After 1 h incubation at 37° C. and 5% CO2, 40 nl of 3 mM 4NQO in 100% DMSO was added to all wells by acoustic dispensing, except minimum control wells which were left untreated with 4NQO to generate a null response control. Plates were returned to the incubator for a further 1 h. Then cells were fixed by adding 20 μl of 3.7% formaldehyde in PBS solution and incubating for 20 mins at r.t. Then 20 μl of 0.1% Triton X100 in PBS was added and incubated for 10 minutes at r.t., to permeabalise cells. Then the plates were washed once with 50 μl/well PBS, using a Biotek EL405 plate washer. Phospho-Chk1 Ser 345 antibody (Cell Signalling Technology #2348) was diluted 150 fold in PBS containing 0.05% polysorbate/Tween and 15 μl was added to each well and incubated over night at r.t. The next morning plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and then 20 μl of secondary Ab solution, containing 500 fold diluted Alexa Fluor 488 Goat anti-rabbit IgG (Molecular Probes #A-11008) and 0.002 mg/ml Hoeschst dye (Molecular Probes #H-3570), in PBST, was added. After 2 h incubation at r.t., the plates were washed three times with 50 μl/well PBS, using a Biotek EL405 plate washer, and plates were then sealed with black plate seals until read. Plates were read using an ArrayScan VTI instrument, using an XF53 filter with 10× objective. A two laser set up was used to analyse nuclear staining with Hoeschst (405 nm) and secondary antibody staining of pChk1 (488 nm).

UniProt: P35270
Assay: LC/MS assay: To screen for SPR inhibition, a biochemical assay based on LC/MS (and chromogenic) read-out has been developed. The LC/MS assay monitors the product formation (L-biopterin) and the chromogenic assay measures OD at 420 nm.N-methoxyacetyl serotonin was used as a reference compound (positive control). The IC50 measured using the screening conditions was 20-40 nM, which agrees with the literature (Smith et al., Journal of Biological Chemistry, 297:5601, 1992).The exemplary assay protocol uses the following conditions: SPR (6 nM); L-Sepiapterin (50 uM); NADPH (100 uM); Na-Phosphate buffer, pH 6.5 (100 mM); 82 uL assay volume; 60 minutes incubation with compounds (0.5% final concentration in DMSO) at 37° C. in Greiner uClear 384 well plates.The following experimental procedure was applied:    (1) Add 2 uL compound (inhibitor) dilutions (20% DMSO) in Greiner uClear 384 well plates.    (2) Add 40 uL enzyme/assay buffer.

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.

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.

Assay: In Vitro BACE Cell-Based Assay: The cell-based assay measures inhibition or reduction of Aβ40 in conditioned medium of test compound treated cells expressing amyloid precursor protein. Cells stably expressing Amyloid Precursor Protein (APP) were plated at a density of 40K cells/well in 96 well plates (Costar). The cells were cultivated for 24 hours at 37° C. and 5% CO2 in DMEM supplemented with 10% FBS. The test compounds were then added to cells in 10-point dose response concentrations with the starting concentration being either 100 uM or 10 uM. The compounds were diluted from stock solutions in DMSO and the final DMSO concentration of the test compounds on cells was 0.1%. After 24 h of incubation with the test compounds the supernatant conditioned media was collected and the Aβ 40 levels were determined using a sandwich ELISA.

Assay: c-Src and Syk Enzyme Inhibition Assay: The inhibitory activities of compounds of the invention against c-Src and Syk enzymes (Invitrogen), are evaluated in a similar fashion to that described hereinabove. The relevant enzyme (3000 ng/mL or 2000 ng/mL respectively, 2.5 uL) is incubated with the test compound (either 4 ug/mL, 0.4 ug/mL, 0.04 ug/mL, or 0.004 ug/mL, 2.5 uL each) for 2 hr at RT. The FRET peptides (8 uM, 2.5 uL), and appropriate ATP solutions (2.5 uL, 800 uM for c-Src, and 60 uM ATP for Syk) are then added to the enzymes/compound mixtures and incubated for 1 hr. Development reagent (protease, 5 uL) is added for 1 hr prior to detection in a fluorescence microplate reader (Varioskan Flash, ThermoFisher Scientific).

Assay: Biological Assay: Assay Method 1: T84 frozen pellets (contents of 1-4x15 cm culture dishes) were homogenized in 300 mL of FAAH assay buffer (125 mM Tris, 1 mM EDTA, 0.2% glycerol, 0.02% Triton X-100, 0.4 mM Hepes, pH 9). The assay mixture was prepared from 50 uL of the cell homogenate, 10 uL of the test compound, and 40 uL of anandamide [1-3H-ethanolamine] (3H-AEA; Perkin-Elmer, 10.3 Ci/mmol), which was added last, for a final tracer concentration of 200 nM. The reaction mixture was incubated at rt for 1 hour (h). During the incubation, 96-well Multiscreen filter plates (catalog number MAFCNOB50; Millipore, Bedford, Mass., USA) were loaded with 25 uL of activated charcoal (Multiscreen column loader, catalog number MACL09625, Millipore) and washed once with 100 uL of MeOH. Also during the incubation, 96-well DYNEX MicroLite plates (catalog number NL510410) were loaded with 100 uL of MicroScint40 (catalog number 6013641, Packard Bioscience, Meriden, Conn., USA).

UniProt: O60674
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.
