PH-SENSITIVE BLOCK COPOLYMER FORMING POLYIONIC COMPLEX MICELLE, AND DRUG OR PROTEIN DELIVERY VEHICLE USING SAME

摘要

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