Peptide-Decorated Dendrimers and Their Bioapplications.

Peptide-decorated dendrimers (PDDs) are a class of spherical, regular, branched polymers that are modified by peptides covalently attached to their surface. PDDs have been used as protein mimetics, novel biomaterials, and in a wide range of biomedical applications. Since their design and development in the late eighties, poly-l-lysine has been a preferred core structure for PDDs. However, numerous recent innovations in polymer synthesis and ligation chemistry have re-energized the field and led to the emergence of well-defined peptide dendrimers with more diverse core structures and functions. This Minireview highlights the development of PDDs driven by significantly improved ligation chemistry incorporating structurally well-defined peptides and the emerging use of PDDs in imaging and drug development.
