Self-assembly of trifunctional tripeptides to form neural scaffolds.

Peptide self-assembly has been exploited to generate a multitude of biomaterials that exhibit biocompatibility due to their similarity to naturally occurring proteins. Previously, we have shown that β-tripeptides self-assemble despite containing sterically bulky, functional sidechains. Herein, we describe the synthesis of a novel β-amino acid to allow for the synthesis of a trifunctional β-tripeptide that remarkably maintains self-assembly and acts as a bioactive neuronal scaffold. These scaffolds show promise for studies involving neuronal cell growth and development.
