Ring structure modifications of phenylalanine 19 increase fibrillation kinetics and reduce toxicity of amyloid β (1–40)†
Abstract
We investigated the influence of the chemical structure of the phenylalanine side chain in position 19 of the 40 residue amyloid β peptide. Side chain modifications in this position yielded fibrils of essentially unaltered morphology, structure, and dynamics, but significantly increased fibrillation kinetics and diminished the toxicity of the peptides.
