InChIKey: GSLXZIRPXIIFQZ-UHFFFAOYSA-N
Target: Voltage-gated inwardly rectifying potassium channel KCNH2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q12809
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.

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.

Target: Beta-secretase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: P56817
Assay: Fluorescence Resonance Energy Transfer (FRET) Assay: Potency of test compounds were determined by measurement of their inhibition of BACE1 activity toward a fluorescent substrate. Experiments were performed by reference to the procedure as described in Ermolieff, et al. (Biochemistry 39:12450-12456 (2000), the teachings of which are incorporated hereby in their entirety). Briefly, the recombinant protease unit of BACE1 was prepared from E. coli expression as inclusion bodies, refolded, and purified as described in Lin, et al., (Proc. Nat. Acad. Sci. 97:1456-1460 (2000)). Fluorogenic substrate, MCA-SEVNLDAEFK(DNP)-NH2 (SEQ ID NO:1) was purchased. (M-2485, Bachem Americas, Torrance, Calif.). The substrate was derived from 10 amino acids of the human amyloid precursor protein (APP), with the Swedish variant amino acids at the beta-secretase cleavage site. The terminal amino acid was modified from arginine to lysine to facilitate derivatization with a functional group for detection by autofluorescence.

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: Fluorescence Polarization: Bcl-xL and Bcl-2 FP binding affinity of compound(s) of Formulae (I), (I-a), (I-b), (I-c), (I-d) and/or (I-e) may be determined using a variety of known methods. One such assay is a sensitive and quantitative in vitro binding assay using fluorescence polarization ("FP") described by Wang, J.-L.; Zhang, Z-J.; Choksi, S.; Sjam. S.; Lu, Z.; Croce, C. M.; Alnemri, E. S.; Komgold, R.; Huang, Z. Cell permeable Bcl-2 binding peptides: a chemical approach to apoptosis induction in tumor cells. Cancer Res. 2000, 60, 1498-1502).Additionally, the binding affinity of compound(s) of Formulae (I), (I-a), (I-b), (I-c), (I-d) and/or (I-e) to Bcl-2 protein in vitro was determined by a competitive binding assay based on fluorescence polarization. For example, fluorescence polarization ("FP") assays may be developed using a c-terminal 6.times.HIS tagged Bcl-2 (aa 1-204) and a C-terminal 6.times.HIS tagged Bcl-X.sub.L (aa 1-209). The tracer may be a synthetic peptide BH-3 peptide Bim conjugated to Fluores.

The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 mL 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 ambient temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction.

Assay: HTRF Assay: The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 mL 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 ambient temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction.
