Abstract :

The accumulation of amyloid beta peptide Aβ1-42 in the brain is a critical early event in the progression of Alzheimer's disease. Four floavonoid compounds isolated from Psoralea fruits (PF) were found to have anti-Alzheimer properties in vitro and in vivo in recent research. These natural compounds inhibited Aβ1-42 aggregation in a promising way. Docking studies and molecular dynamics (MD) simulations were used in our work to conduct a molecular modeling study on the substances as potential Aβ1-42 aggregation inhibitors. A molecular mechanics calculation was performed to determine the binding free energy, gain insight into the binding modes of the ligands, and pinpoint the key interacting residues.
