The aim of the present work is the development of highly efficient targeting molecules to specifically address mesoporous silica nanoparticles (MSNs) designed for the photodynamic therapy (PDT) of prostate cancer. We chose the strategy to develop a novel compound that allows the improvement of the targeting of the cation-independent mannose 6-phosphate receptor, which is overexpressed in prostate cancer. This original sugar, a dimannoside-carboxylate (M6C-Man) grafted on the surface of MSN for PDT applications, leads to a higher endocytosis and thus increases the efficacy of MSNs.
本工作的目标是开发高效的靶向分子,专门针对设计用于前列腺癌光动力疗法(PDT)的介孔二氧化硅纳米颗粒(MSNs)。我们选择了开发一种新化合物的策略,该化合物可以改善在前列腺癌中过度表达的独立于阳离子的甘露糖6磷酸受体的靶向性。这种原始糖,一种二甘露糖基-羧酸酯(M6C-Man)被嫁接在用于PDT应用的MSN表面,导致更高的内吞作用,从而提高了MSNs的功效。
