Polysaccharide-block-polypeptide copolymer vesicles: towards synthetic viral capsids

Angew Chem Int Ed Engl. 2009;48(14):2572-5. doi: 10.1002/anie.200805895.

Abstract

Natural inspiration: Amphiphilic polysaccharide-block-polypeptide copolymers were synthesized by click chemistry from dextran end-functionalized with an alkyne group and poly(gamma-benzyl L-glutamate) end-functionalized with an azide group. The ability of these copolymers to self-assemble into small vesicles (see picture) suggests the possibility of a new generation of drug- and gene-delivery systems whose structure mimics that of viruses.
