产品描述 | Donepezil (Aricept) is a piperidine-based, potent, specific, and reversible inhibitor of acetylcholinesterase (AChE). It can be used for the treatment of mild to moderate dementia of the Alzheimer's type. |
靶点活性 | AChE (human):11.6 nM, AChE (bovine):8.12 nM |
体外活性 | Donepezil has 500-1000-fold more selective for AChE over butyrylcholinesterase (BuChE). Short- and long-exposure of SH-SY5Y human neuroblastoma cells to donepezil induces a concentration-dependent inhibition of cell proliferation unrelated to muscarinic or nicotinic receptor blockade or apoptosis. Donepezil reduces the number of cells in the S-G2/M phases of the cell cycle, increases the G0/G1 population, and reduces the expression of two cyclins of the G1/S and G2/M transitions, cyclin E and cyclin B, in parallel with an increase in the expression of the cell cycle inhibitor p21. In addition, donepezil increases action potential-dependent dopamine release and modulates nicotinic receptors of substantia nigra dopaminergic neurons[1]. |
体内活性 | In plasma, urine, and bile, most donepezil metabolites are O-glucuronides. After oral ingestion, peak plasma concentrations are achieved in 3-5 hours and its absorption is not affected by food. Donepezil is slowly absorbed from the gastrointestinal tract and has a terminal elimination half-life of 50-70 hours in young volunteers (>100 hours in elderly subjects). After extensive metabolization in the liver, the parent compound is 93% bound to plasma proteins. Donepezil is metabolized in the liver via the cytochrome P450 system (CYP1A2-, CYP2D6-, CYP3A4-related enzymes). In animals, donepezil is found unchanged in the brain, and no metabolites are detected in the nervous tissue. Donepezil has linear pharmacokinetics over a dose range of 1-10 mg/day. 96% of circulating donepezil is protein bound [1]. |
细胞实验 | Cell lines: retinal ganglion cells (RGCs). Concentrations: 0.1-10 μM. Incubation Time: 3 days. RGC survival after exposure to each reagent (glutamate, donepezil, tacrine, galanthamine, and HA14-1) is measured by calcein-AM staining after 3 days in culture, Briefly, cells are incubated in 1 μM calcein-AM in PBS for 15 minutes at 37℃. After the medium is replaced with fresh PBS, cells are examined under a fluorescence microscope using a fluorescein filter. The total number of surviving RGCs defined as cells with a calcein-AM stained cell body and a process extending at least two cell diameters from the cell body is counted in each well. The number of surviving RGCs without any drug served as a control. |
动物实验 | Animal Models: male C57BL/6 wild-type and CGRP(?/?) mice (10-12 weeks old, 21–24 g). Formulation: added to the food powder. Dosages: 1.5 mg/kg (i.g.) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
