title: Functionalized micellar assemblies prepared via block copolymers synthesized by living free radical polymerization upon peptide-loaded resins.
abstract: Hybrid peptidic-synthetic amphiphilic block copolymers, synthesized by living free radical polymerization (LFRP) on solid support, have been utilized as precursors for nanoscale materials possessing bio-available peptides. LFRP initiators, coupled to the peptide terminus upon the resin, facilitated the growth of homo- and block copolymers via nitroxide mediated radical polymerization (NMRP) or atom transfer radical polymerization (ATRP). Herein, the versatile solid-support synthesis of the antimicrobial peptide tritrpticin, coupling of living free radical polymerization initiators to the peptide-loaded resin, and the controlled radical polymerization of various monomers to yield amphiphilic diblock copolymers are described. Assembly of the peptidic-synthetic block copolymers into micelles and a preliminary assessment of their in vitro biological properties are detailed.
