advances in foldamer chemistry, tailored delivery systems based on foldamer architectures, which provide a high level of control over secondary structure, are curiously rare among non‐viral technologies for transporting nucleic acids into cells. A potent pH‐responsive, bioreducible cell‐penetrating foldamer (CPF) was developed through covalent dimerization of a short (8‐mer) amphipathic oligourea sequence
尽管折叠剂化学取得了重大进展,但基于折叠剂体系结构的量身定制的递送系统可提供对二级结构的高度控制,在非病毒性技术中,将核酸转运到细胞中的技术却很少见。通过对带有组氨酸类型单元的短(8-mer)两亲性少尿序列进行共价二聚作用,开发出了一种有效的pH响应,可生物还原的细胞穿透性折叠剂(CPF)。该CPF表现出与pDNA组装的高能力,并介导核酸向细胞内的有效传递。此外,它不会对细胞生存能力产生不利影响,并且已证明与基于His-rich序列的同源肽转染剂相比具有优势。
