Abstract

We propose a method to improve the enhanced permeability and retention (EPR) effect of nanomedicines based on tumor-specific vasodilation using a nitric oxide (NO) donor-containing liposome. NONOate, a typical NO donor, was incorporated into a PEGylated liposome to retard the protonation-induced release of NO from NONOate by the protecting lipid bilayer membrane. The NONOate-containing liposome (NONOate-LP) showed similar blood retention to an empty PEGylated liposome but almost twice the amount accumulated within the tumor. This improvement in the EPR effect is thought to have been caused by specific vasodilation in the tumor tissue by NO released from the NONOate-LP accumulated in the tumor. The improved EPR effect by NONOate-LP will be useful for the accumulation of co-administered nanomedicines.
