Computational Investigation of Stilbenoids as Aggregation Inhibitors of Amyloid β as it Relates to Alzheimer’s Disease

Alzheimer’s disease (AD) is a brain degenerative disorder resulting in memory loss and decline of the ability to function independently. It is the most common cause of dementia and a leading cause of death in the U.S. Scientists believe Alzheimer’s occurs due to the buildup of plaques created by the aggregation of protein fragments, called amyloid beta (Aβ), on nerve cells. Currently, there is no cure; therefore, further research is important. Using computational chemistry methods, interactions between potential drug molecules and Aβ can be modeled to better understand the development of AD. This project determines the binding interactions between potential polyphenol drug molecules and Aβ using molecular dynamics and analyzes the structural changes of Aβ in the presence of these polyphenols. Ultimately, this computational research aids in the mechanistic understanding of the protein-drug interactions that disaggregate Aβ and the development as a novel drug treatment to combat Alzheimer’s Disease.
