Metallodithiolate Ligands For Reversing Metal Ion Induced Aggregation Of Beta Amyloid, Eleanor K. Adams, Marilyn Rampersad Mackiewicz

Student Research Symposium

Alzheimer’s Disease (AD) is the sixth leading cause of death in the United States with no known methods to cure, reverse or halt disease progression. The “metal hypothesis” states that Fe^II, Cu^II, Zn^II, and Al^II bind to truncated Aβ peptides and form soluble oligomers which deposit as senile plaques. These plaques play a crucial role in AD pathogenesis. For example, metallated-Aβ aggregates are hypothesized to disrupt membranes or generate a reactive oxygen species (ROS) through redox cycling in the presence of Cu^I/II or Fe^III/II and a reducing agent. ROS can lead …
