Biological Activity

Description Donepezil is a specific and potent AChE inhibitor for bAChE and hAChE with IC50 of 8.12 nM and 11.6 nM , respectively.
Targets
bAChE [1] hAChE [1]
8.12 nM 11.6 nM
In vitro

Donepezil inhibits the carbachol-stimulated increase in intracellular Ca2+ concentration in human SHSY5Y neuroblastoma cells in a concentration dependent manner, indicating that Donepezil have muscarinic antagonist activity. [2] A recent study shows that Donepezil can protect human umbilical vein endothelial cells (HUVECs) against H2O2-induced cell injury. This may be useful as a potential therapy for oxidative stress in cardiovascular and cerebrovascular diseases. [3]

In vivo Intraperitoneal administration of Donepezil in rats produces a dose dependent increase in salivation and tremor, which are overt cholinergic behavioural signs, with an ED50 of 6 μmol/kg. Donepezil is found to be somewhat less potent with a ED50 of 50 μmol/kg following oral administration. [2]. When administered separately in vivo, 5-HT(4) receptor inducer, RS67333 (0.3 and 1 mg/kg) and Donepezil (1 mg/kg) improves recognition performances compared to saline treated mice, while co-administration of subactive doses of RS67333 (0.1mg/kg) and Donepezil (0.3 mg/kg) improves memory. However, this improvement is prevented if a 5-HT(4)R antagonist (GR125487, 10 mg/kg) is also administered. [4]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
