pH-Responsive de-PEGylated nanoparticles based on triphenylphosphine–quercetin self-assemblies for mitochondria-targeted cancer therapy†
Abstract
We have developed mitochondria-targeted self-assembled nanoparticles (NPs) based on amphiphilic triphenylphosphine–quercetin (TPP–Que) conjugates, which were further modified by poly(ethylene glycol) via a pH-responsive coordination bond to form TQ-PEG NPs. And it is revealed that the TQ-PEG NPs were more effective therapeutic agents compared with Que in vitro and in vivo.
