Impact of Drug Conjugation Site and Corona Chemistry on the Therapeutic Activity of Polymer Nanorod - Drug Conjugates.

ABSTRACT: Biocompatible rod-shaped nanoparticles of controlled length can be produced through the heat-induced "living" seeded crystallization-driven self-assembly (CDSA) of poly(2-isopropyl-2-oxazoline)-containing block copolymers. With a hydrophilic poly(2-methyl-2-oxazine) or poly(2-methyl-2-oxazoline) corona, these nanorods have proven non-cytotoxic, non-hemolytic, and ideal for use as a polymer-based drug delivery system. This study demonstrates a facile, one-pot method for the synthesis of mycophenolic acid (MPA)-conjugated block copolymer "unimers" for use in seeded CDSA. Through altering block order during sequential monomer addition cationic ring-opening polymerization (CROP), MPA is conjugated to either the chain end of the core-forming or corona-forming block. This allows bioactive polyme
