Abstract

The terminally protected peptide Boc-Leu-Val-Phe-Phe-Ala-OMe bearing sequence similarity with the central hydrophobic cluster (CHC) of Alzheimer’s Aβ17-21 peptide self-assembles to produce amyloid-like straight unbranched fibrils from organic solvents. The fibrils readily bind with a physiological dye Congo red (CR) and exhibits green gold birefringence under polarized light, a characteristic feature of amyloid plaque obtained from many neurodegenerative diseases. FTIR spectroscopy and in silico energy minimization study shed some light on the antiparallel supramolecular β-sheet aggregation of the peptide.
