Glutathione responsive poly(HPMA) conjugate nanoparticles for efficient 6-MP delivery†
Abstract
The anticancer drug 6-MP was covalently bonded to the –OH group of poly(HPMA) via a glutathione-responsive carbonyl vinyl sulfide linker. In vitro simulation assay demonstrated that the poly(HPMA)–PTA conjugate exhibited a markedly enhanced antitumor effect on HepG2 cells.
