Protocol

Cell experiment [1,2]:

Cell lines

Human SHSY5Y neuroblastoma cells, human umbilical vein endothelial cells

Preparation method

Limited solubility. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1 h

Applications

Donepezil dose-dependently inhibited the carbachol-stimulated increase in intracellular Ca2+ concentration in human SHSY5Y neuroblastoma cells with the IC50 of 4.0 ± 0.2 μM. Donepezil protected human umbilical vein endothelial cells (HUVECs) against H2O2-induced cell injury. Donepezil (100 μM) decreased cell viability. Pretreatment with donepezil at concentrations of 1 and 10 μM significantly inhibited the H2O2–induced reduction in cell viability. Exposure of HUVECs to donepezil (1 μM) for 2 h upregulated HIF-1α expression.

Animal experiment [1,3]:

Animal models

Male Lister Hooded rats, adult male NMRI mice

Dosage form

Intraperitoneal administration, 1 mg/kg

Application

In Male Lister Hooded rats, donepezil dose-dependently increased salivation and tremor with an ED50 of 6 μmol/kg. In adult male NMRI mice, donepezil (1 mg/kg) improved recognition performances.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Donepezil Hydrochloride (Donepezil HCL) is a novel, potent and selective inhibitor of acetylcholinesterase (AChE), an enzyme possibly involved in cognitive dysfunction of patients suffering Alzheimer’s disease (AD), with the half maximal inhibition concentration IC50 value of 6.7 nM [1].

Donepezil HCL is a piperidine-class AChE inhibitor containing an N-benzylpiperdine and an indanone moiety, which confers it a longer and more selective action against AchE as compared to BuChE (IC50: 7.4 μM) [1].

Donepezil HCL has been approved by FDA for the treatment of AD, in which it has improved cognitive function of mild to severe moderate AD patients and exhibited excellent tolerability without hepatotoxicity [1].

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.
