Assay: Fluorescence-Based Assay: Chinese hamster ovary (CHO) cells overexpressing the human S1P2 gene were cultured in a Ham's F12 medium containing 10% fetal bovine serum (FBS), an antibiotic/antifungal agent and G418. CHO cells overexpressing the rat S1P2 gene were cultured in a Ham's F12 medium containing 10% FBS, penicillin/streptomycin and blasticidin S. The cultured cells were incubated in a Fura2-AM solution (5 uM) [a Ham's F12 medium containing FBS (10%), HEPES buffer (20 mM, pH 7.2 to 7.5) and probenecid (2.5 mM)] at 37 C. for 60 minutes. The cells were washed twice with a Hanks' balanced saline containing HEPES buffer (20 mM, pH 7.2 to 7.5) and probenecid (2.5 mM) and immersed in the same solution. A plate was mounted on a fluorescence-based drug screening system and the intracellular calcium ion concentration was measured for 30 seconds without stimulation.

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: 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.

Assay: Time Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Assay: Potency of compounds were also measured using another fluorogenic substrate, TruPoint BACE1 Substrate Eu-CEVNLDAEFK-QSY 7 (SEQ ID NO:3) (AD0258, PerkinElmer, Boston Mass.). This substrate also has Swedish variant amino acids at the β-secretase cleavage site, with a fluorescent europium (Eu) chelate coupled to one end and a quencher of europium fluorescence (QSY7) coupled to the other end via lysine. If the sample contains BACE1 activity, the Eu chelate and the quencher will be separated as the substrate is cleaved. The Eu-signal increases and it can be measured by time-resolved fluorometry, EnVision, 30 minutes after the substrate (final concentration 300 nM) was added.

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.

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: 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.
