abstract = {It is widely believed that Alzheimer's disease pathogenesis
is driven by the production and deposition of the amyloid-β
peptide (Aβ) in the brain. In this study, we employ a
combination of in silico and in vitro approaches to
investigate the inhibitory properties of selected
arginine-rich D-enantiomeric peptides (D-peptides) against
amyloid aggregation. The D-peptides include D3, a 12-residue
peptide with anti-amyloid potencies demonstrated in vitro
and in vivo, RD2, a scrambled sequence of D3, as well as
truncated RD2 variants. Using a global optimization method
together with binding free energy calculations followed by
molecular dynamics simulations, we perform a detailed
analysis of D-peptide binding to Aβ monomer and a fibrillar
Aβ structure. Results obtained from both molecular
simulations and surface plasmon resonance experiments reveal
a strong binding of D3 and RD2 to Aβ, leading to a
significant reduction in the amount of β structures in both
monomer and fibril, which was also demonstrated in
Thioflavin T assays. The binding of the D-peptides to Aβ is
driven by electrostatic interactions, mostly involving the
D-arginine residues and Glu11, Glu22 and Asp23 of Aβ.
Furthermore, we show that the anti-amyloid activities of the
D-peptides depend on the length and sequence of the
Dpeptide, its ability to form multiple weak hydrophobic
interactions with Aβ, as well as the Aβ oligomer size.},
