论文部分内容阅读

Polypeptide drugs cause increasing attention due to their application in clinical treatment.On the one hand, many linear peptides have good stability and biological activity in vitro, they degradate rapidly in vivo.On the other hand, cyclopeptide molecules possess relatively stable conformations.

基于可降解聚酯-小分子PEI的非病毒基因载体

研究安全有效的基因载体己成为基因治疗成功的最重要因素之一.目前,PEI25 kDa被认为是聚合物类非病毒基因转染载体的"黄金标准",但是高的毒性抑制了它的应用.与之相对,小分子PEI的毒性很低,但是转染效率却非常低,也不能很好的用作基因载体.将小分子PEI通过可降解化学键进行桥联是提高其转染效率并保持低细胞毒性的有效方法.
