POLYION COMPLEX OF POLY(L-ARGININE) SEGMENT-CONTAINING BLOCK COPOLYMER AND POLYANIONIC POLYMER

摘要

[Problem] To provide a composition that can become an effective arginine matrix for intratumoral inducible NO synthase (iNOS). [Solution] A polyion complex (PIC) of PEG-b-poly(L-Arg) or poly(L-Arg)-b-PEG-b-poly(L-Arg) and a polyanionic polymer, and the use of the complex.
