生物活性

製品説明 Donepezil (Aricept, Donepezilo) is a piperidine based, potent, specific, non-competitive and reversible inhibitor of acetylcholinesterase (AChE) used for the treatment of mild to moderate dementia of the Alzheimer's type.
in vitro Donepezil has reversible and noncompetitive inhibition effects on AChE. It 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].
in vivo 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 brain, and no metabolites are detected in the nervous tissue. 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 absortion is not affected by food. Donepezil has linear pharmacokinetics over a dose range of 1-10 mg/day. 96% of circulating donepezil is protein bound[1].

実験の流れ

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.
