pH-SENSITIVE BLOCK COPOLYMER MAKING POLYIONIC COMPLEX MICELLES AND DRUG OR PROTEIN DELIVERY CARRIERES USING THEREOF

摘要

The present invention relates to a pH-sensitive block copolymer and a drug or protein carrier using the same to form a diionic complex micelle, and more specifically, (a) polyethylene glycol-based compound; (b) poly (amino acid) compounds; And (c) a pH-sensitive block copolymer forming a diionic complex micelle formed by copolymerizing a heterocyclic alkylamine-based compound having an ionic complex inducing ability and a drug or protein carrier using the same.
