A versatile polycation scaffold that can easily be modified with targeting ligands has been designed, synthesized, and characterized. A series of galactose‐containing polymers has been produced to demonstrate the ease of modification of this polynucleotide delivery vehicle motif via the click reaction and to study how various structural modifications affect recognition by ASGPr on hepatocytes. A small
已经设计,合成和表征了可以容易地用靶向配体修饰的通用聚阳离子支架。已生产出一系列含半乳糖的聚合物,以证明通过点击反应对该多核苷酸递送载体基序进行修饰的简便性,并研究各种结构修饰如何影响ASGPr对肝细胞的识别。创建了一个小的结构库,其中靶向基团和聚合物主链之间的DCS和烷基间隔基长度发生了变化。所描述的新型聚合物支架被证明是了解以受体为靶标的聚合物制成的复合物的结构/活性关系的宝贵工具。
