Abstract
A very stable binding site for the interaction between a pentameric oligothiophene and an amyloid-β(1-42) fibril has been identified by means of non-biased molecular dynamics simulations. In this site, the probe is locked in an all-trans conformation with a Coulombic binding energy of 1200 kJ mol -1 due to the interactions between the anionic carboxyl groups of the probe and the cationic ϵ-amino groups in the lysine side chain. Upon binding, the conformationally restricted probes show a pronounced increase in molecular planarity. This is in line with the observed changes in luminescence properties that serve as the foundation for their use as biomarkers.
