Abstract:

Anti-inflammatory and lipid-lowering are currently effective strategies for the treatment of atherosclerosis. Therefore, a nanomedicine delivery system with targeted, photothermal therapy synergistic drug therapy was designed and synthesized to slow the progression of atherosclerosis through lipid-lowering and anti-inflammatory effects. The CD44 receptor overexpressed in inflammatory macrophages was targeted by using hyaluronic acid as a backbone. Ag2S quantum dots exert photothermal therapeutic effects through covalent binding, while lovastatin is encapsulated to realize the pharmacological therapeutic effect. Moreover, physicochemical analyses and cellular experiments were performed on this nanomedicine delivery system. The results show that the material has suitable dimensions for good drug release in the presence of hyaluronidase and exerts excellent photothermal effects. In addition, both in vitro and in vivo experiments demonstrate that the material has good biocompatibility and inhibits the developmental process of atherosclerosis, which provides new insights into the development of safe and effective treatments for atherosclerosis.

Key words: Hyaluronic acid, Nanomedicine delivery system, Quantum dots, Photothermal therapy, Atherosclerosis
