Abstract

The vascular endothelium plays an important role in regulating vascular homeostasis. Damage to the endothelium can lead to cardiovascular diseases such as arteriosclerosis. Therefore, early-stage detection and evaluation of vascular endothelium dysfunction would be very important for effective diagnosis and therapy. We synthesized a polymeric drug carrier bearing an Evans blue analogue as a probing unit for endothelium injury. The polymeric carrier spontaneously formed stable nanoparticles with micelle-like structure in aqueous media and could encapsulate hydrophobic doxorubicin (DOX). The encapsulated DOX showed a sustainable release profile over a period of 10-60 h depending on the loaded DOX concentration. The polymeric carrier specifically adsorbed against the endothelium-injured site in extracted porcine aorta. These properties of the polymeric drug carrier will be suitable for specific drug delivery to endothelium dysfunctional region.
