Alzheimer’s disease is a neurodegenerative and incurable disease that is associated with the amyloid beta (Aβ) aggregation. We have carried out comparative molecular dynamics simulations of a 6-mer peptide and its analogues to elucidate the inhibitory mechanism on Aβ aggregation. The top analogue screened after refinement via docking exhibited significant inhibitory activities on both Aβ17–42 fibril as well as Aβ1–42 monomer, leading to disassembly of β-strands of Aβ1–42 peptide and fibril by interacting with C-terminal residues via hydrogen bonds and hydrophobic contacts. Binding of the analogue to the C-terminal region proves to be significant.Keywords
