title: Computational pharmaceutical analysis of anti-Alzheimer's Chinese medicine             Coptidis Rhizoma alkaloids.
abstract: Alzheimer's disease (AD) is an age-related neurodegenerative disease, affecting             over 20 million people worldwide. Until recently, two major hypotheses were proposed             regarding the molecular mechanism of pathogenesis: the cholinergic hypothesis             and the amyloid cascade hypothesis. At present, acetylcholinesterase inhibitors             are the most effective therapy for AD. Most pharmacological research has focused             on the ability of acetylcholinesterase to alleviate cholinergic deficit and improve             neurotransmission. Coptidis rhizoma and its isolated alkaloids are reported to             possess a variety of activities, including neuroprotective and antioxidant effects.             However, as yet no theoretical analysis exists to support this hypothesis. To             examine this theory, we applied a computational pharmaceutical analysis to reveal             that Chinese medicine Coptidis rhizoma alkaloids have much higher activities than             Donepezil (commercial name is Aricept) by docking and scoring.
