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 ul 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: Cellular Assay of Aβ Production: Test Example 3: The potency of compounds against BACE1 activity was determined in a cellular assay of Aβ production. Human SK-N-BE(2) neuroblastoma cells (ATCC No. CRL-2271) were plated at 96,000 cells/well/100 uL in 96-well plates in RPMI1640 medium/10% fetal bovine serum (FBS)/penicillin-streptomycin and cultured for 24 hours at 37° C., 5% CO2. Test compounds were dissolved in dimethyl sulfoxide and diluted with dimethyl sulfoxide and put into RPMI1640/5% FBS/penicillin-streptomycin media (final dimethyl sulfoxide concentration is 0.5%). The culture media in 96-well plates were replaced by 125 uL/well of the media containing test compounds. After incubation for 6 hours at 37° C., 5% CO2, 30 uL of the media were transferred into a fresh 96-well plate and used for Aβ40 assay by an enzyme-linked immunosorbent assay (ELISA) kit (#27718, Immuno-Biological Laboratories, Japan) according to the manufacturer's protocol. Cell viability was measured by CellTiter-Glo Luminescent Cell Viability Assay (#7571, Promega) after removal of 30 uL of the media for the Aβ assay.

Assay: Inhibition Assay: The hERG potassium current was measured in a hERG-stably-expressing Chinese hamster ovary K1 (CHO) cells. The experiments were performed using an automated planar patch-clamp system QPatch HTX (Sophion Bioscience A/S). The application of pressure for forming gigaseals and whole-cell patch clamp configuration were established using the QPatch assay software. Patch-clamp experiments were performed in voltage-clamp mode and whole-cell currents were recorded. The following stimulation protocol was applied to investigate the effects of compounds on hERG potassium channel.The membrane potential was held at −80 mV and repetitively (every 15 seconds) depolarized to +20 mV for 4800 milliseconds after the pulse to −50 mV for 20 milliseconds served to define the baseline, followed by repolarizing step to −50 mV for 5000 milliseconds to evaluate of the tail current amplitude. Experiments were conducted at room temperature.
