摘　　要：靶向给药系统由于能够在特定部位实现药物的靶向释放而受到研究人员的广泛青睐,其中主动靶向给药系统被认为是最有前途的靶向给药系统。然而,用于构建多功能药物载体靶向部分的常用纳米材料存在许多缺点,如生物相容性低、易被单核吞噬细胞系统消除、不易修饰等,限制了其应用。唾液酸是一种天然配体,通常作为糖蛋白或糖脂上聚糖的末端糖存在于细胞表面。作为一种内源性物质,它具有生物安全性高、分子结构均匀清晰、易于化学修饰等特点。唾液酸功能化的纳米颗粒可携带靶向特异性表达其受体(唾液酸结合免疫球蛋白样凝集素或选择素受体)细胞的药物用以治疗疾病。在这篇综述中,我们介绍了目前发表的关于以唾液酸修饰的纳米粒子为基础并结合“唾液酸结合免疫球蛋白样凝集素或选择素受体”的靶向给药系统在肿瘤或炎症中治疗作用的文献,并讨论了天然唾液酸配体的化学修饰方法,用以提高对受体的结合亲和力和选择性。Targeted drug delivery systems are highly desirable for their ability to release drugs specifically at targeted sites.Among these systems,active targeting is considered the most promising.However,the nanomaterials commonly used for constructing the targeting moiety of multifunctional drug delivery vehicles have several disadvantages that limit their applications,such as low biocompatibility,susceptibility to elimination by the mononuclear phagocyte system,and difficulty in modification.Sialic acid,a natural ligand,is often present as the terminal sugar of glycans on glycoproteins or glycolipids on the cell surface.As an endogenous substance,it is highly biocompatible,has a clear molecular structure,and is easy to chemically modify.Sialic acid-functionalized nanoparticles can carry drugs that target cells expressing receptors(sialic acid-binding immunoglobulin-like lectin or selectin receptors)for the treatment of diseases.In the present review,we presented current literature on sialic acid-decorated nanoparticle-based targeted drug delivery systems that bind to“sialic acid-binding immunoglobulin-like lectin or selectin receptors"for therapeutic effects in tumors or inflammation.We also discussed chemical modification strategies for natural sialic acid ligands to improve binding affinity and selectivity to receptors.
