Abstract:The present study expands the versatility of cationic poly(2-oxazoline) (POx) copolymers as a PEG-free platform for gene delivery to immune cells, such as monocytes and macrophages. Several block copolymers are developed by varying non-ionic hydrophilic blocks (poly(2-methyl-2-oxazoline) (pMeOx) or poly(2-ethyl-2-oxazoline) (pEtOx), cationic blocks, and an optional hydrophobic block (poly(2-isopropyl-2-oxazoline) (iPrOx). The cationic blocks are produced by side chain modification of 2-methoxy-carboxyethyl-2-o… Show more
