Abstract |
Alzheimer’s disease (AD) is the most common neurodegenerative disease among the cause of dementia which can appear in the elderly people aged 65 or old. The cause of Alzheimer's disease is not yet known exactly. Alzheimer's drugs based on the cholinergic theory currently marketed for the treatment of AD patient. However, they have some side effects. We have been researching to find out new candidate compounds as cholinesterase inhibitors. In this study, a series of paeonol compounds were synthesized and their in vitro cholinesterase [acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE)] inhibitory activities were evaluated. The structure-activity relationship (SAR) study depended on the Claig plot was carried out ; plotting the sigma constants of the Hammett equation (σ) versus hydrophobicity (π). The IC50 value of compound 5 (+σ, +π) is 0.26 ± 0.06 μM and it is comparable to that of galantamine (IC50 = 12.74 ± 0.86μM against BuChE). |
