Abstract
The disclosure provides a hybrid membrane camouflaged nanomedicine loaded with oxidative phosphorylation inhibitor and preparation method thereof. The nanomedicine comprises an inner core and an outer shell coated on the periphery of the inner core. The inner core is a ROS-responsive drug-loaded nanoparticle, and the drug loaded by the ROS-responsive nanocarrier is an oxidative phosphorylation inhibitor. The outer shell is a hybrid membrane of mitochondrial membrane and cancer cell membrane. The nanomedicines can cross the BBB and reach tumor sites by the homologous targeting of cancer cell membrane, and then they can homologously target and enter mitochondria by the mitochondrial membrane. Subsequently, under the high-level ROS environment of the mitochondria, the ROS responsive drug-loaded nanoparticle releases the oxidative phosphorylation inhibitor due to the swell and degradation of the inner core, so that the safe and efficient targeted GBM therapy is achieved.
