Multicomponent Synthesis of Polyphenols and their in vitro Evaluation as Potential β-Amyloid Aggregation Inhibitors.

While plant polyphenols possess a variety of biological properties, exploration of chemical diversity around them is still problematic. Here, an example of application of the Ugi multicomponent reaction to the combinatorial assembly of artificial, yet "natural-like", polyphenols is presented. The synthesized compounds represent a second-generation library directed to the inhibition of β-amyloid protein aggregation.
