摘要：纳米药物具有靶向和缓释特性,是癌症治疗的重要工具。其中,纳米载体的优化设计是提高抗肿瘤纳米药疗效的关键。有机笼是一种新型的多孔纳米材料,因物理化学性质可调性、模块设计等优势脱颖而出,已广泛应用于纳米生物医药等领域。从动力学及热力学研究出发,构建了一系列不同结构的有机笼及其表面修饰衍生物,研究了该纳米载体的细胞膜输运行为。通过分析有机笼在生物膜输运过程中的动力学及热力学性质发现,有机笼结构形变对生物膜输运起着至关重要的作用;此外,聚乙二醇表面修饰提高了有机笼的靶向识别能力,但使得有机笼更加亲水,进而造成了更高的生物膜输运能垒,阻碍跨膜输运。本文在分子水平上系统地阐述了有机笼与细胞膜相互作用规律,对纳米载体设计和在生物医疗方面的应用提供了理论指导。
Nanomedicines have targeted and sustained-release properties and are important tools for cancer treatment.Among them,the optimized design of nanocarriers is the key to improving the efficacy of anti-tumor nanomedicines.Organic cages(OCs)are an innovative kind of porous nanomaterial that has found widespread use in nanomedicine due to advantages such as physicochemical tenability and modularity design.Based on the dynamics and thermodynamic perspectives,a series of OCs with varied architectures and their derivatives derived surfacemodification were constructed,and their transmembrane transport behavior was studied.The dynamic and thermodynamic properties of OCs during transport were studied.It was discovered that the structural deformation of OCs played an important role in transmembrane transport.Furthermore,surface modification boosts the organic cage's target identification ability while making it more hydrophilic,which causes a larger transmembrane transport energy barrier and hampers transmembrane transport.This article systematically explains the interaction rules between organic cages and cell membranes at the molecular level,providing theoretical guidance for the design of nanocarriers and their application in biomedicine.
