| beta-secretase 1/Beta-secretase 1 in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL4822] [GtoPdb: 2330] [UniProtKB: P56817] | ||||||||
| ChEMBL | Binding affinity to BACE1 (unknown origin) by surface plasmon resonance spectroscopic analysis | B | 3.94 | pKd | 114000 | nM | Kd | J Med Chem (2016) 59: 3732-3749 [PMID:26978477] |
| Kv7.2/Potassium voltage-gated channel subfamily KQT member 2 in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL2476] [GtoPdb: 561] [UniProtKB: O43526] | ||||||||
| ChEMBL | FluxOR potassium ion channel assay: Cell preparation: CHO-KCNQ2 cells were cultured in a 175 cm2 culture flask, and when the cells was grown to a density of 60-80%, the culture medium was removed, washed with 7 mL PBS (Phosphate Buffered Saline) once, then 3 mL 0.25% Trypsin was added to digest. After the digestion was completed, 7 mL culture medium (90% DMEM/F12+10% FBS+500 μg/mL G418) was added to neutralize, centrifugated for 3 minutes at 800 rpm. The supernatant was aspirated, then 5 mL culture medium was added to resuspend, and then the cells were counted.Cell plating: The density to 3×104/well was adjusted according to the results of cell counting. After standing at room temperature for 30 minutes, the cells were placed in a 37° C. CO2 incubator and incubated overnight for 16-18 hours. The cell density reached about 80%.Fluorescent dye incubation: The cell culture medium was discarded, 80 μL/well loading buffer was added, and the cells were incubated in dark at room temperature for 60 minutes.Compound incubation: the loading buffer was discarded, 80 μL/well prepared compound solution was added, incubated at room temperature and in dark for 20 minutes.Fluorescence data collection: FDSS/μCELL instrument for real-time fluorescence is used for signal recording, wherein excitation wavelength was 480 nm, emission wavelength was 540 nm, and signals were recorded 1 times per second, after baseline was recorded for 10 seconds, the addition of 20 μL/well stimulation buffer was started, and then the signal was continuously record until the end of 180 seconds. | B | 5.08 | pEC50 | 8230 | nM | EC50 | US-11365181-B2.
