Design, synthesis, and biological evaluation of glycine-based molecular tongs as inhibitors of Aβ1–40 aggregation in vitro
摘要:
A series of N-terminus benzamides of glycine-based symmetric peptides, linked to m-xylylenediamine and 3,4'-oxydianiline spacers, were prepared and tested as inhibitors of beta-amyloid peptide A beta(1 - 40) aggregation in vitro. Compounds with good anti-aggregating activity were detected. Polyphenolic amides showed the highest anti-aggregating activity, with IC50 values in the micromolar range. Structure - activity relationships suggested that pi - pi stacking and hydrogen-bonding interactions play a key role in the inhibition of A beta(1 - 40) self-assembly leading to amyloid fibrils.
