Conformational stability of Abeta-(25-35) in the presence of thiazolidine derivatives

In the attempt to identify a new lead compound able to modify the conformational preferences of the beta-amyloid peptides, a set of new compounds characterized by a thiazolidine ring linked to several different aryl moieties were synthesized. The ability of these compounds to prevent the beta-amyloid aggregation was evaluated using circular dichroism and nuclear magnetic resonance techniques. Molecular docking procedure allowed an interpretation of spectroscopic in the key of molecular interaction.
