Acetylcholinesterase inhibitors from plants

Abstract

Inhibition of acetylcholinesterase (AChE), the key enzyme in the breakdown of acetylcholine, is considered as a promising strategy for the treatment of neurological disorders such as Alzheimer's disease, senile dementia, ataxia and myasthenia gravis. A potential source of AChE inhibitors is certainly provided by the abundance of plants in nature. This article aims to provide a comprehensive literature survey of plants that have been tested for AChE inhibitory activity. Numerous phytoconstituents and promising plant species as AChE inhibitors are being reported in this communication. © 2007 Elsevier GmbH. All rights reserved.
