gene delivery systems to overcome extracellular and intracellular barriers is a critical issue for future clinical applications of gene therapy. In recent years much effort has been focused on the development of a variety of DNA carriers, and cationic liposomes have become the most common non-viral gene delivery system. Solid-phase synthesis was used to produce three libraries of polyamine-based cationic
非病毒基因传递系统克服细胞外和细胞内壁垒的能力是基因治疗未来临床应用的关键问题。近年来,许多努力集中在各种DNA载体的开发上,阳离子脂质体已成为最常见的非病毒基因递送系统。固相合成用于生产三个具有多种疏水性尾巴的多胺基阳离子脂质文库。这些被表征,并且当配制成阳离子脂质体时,确定这些化合物的DNA结合和转染能力的结构-活性关系。两种阳离子脂质产生了人类细胞的高效转染。令人惊讶的是,这两种化合物均来自该文库,具有两个头基和一个脂族尾基,被认为是去污剂样的化合物类别,对转染的研究很少。这些阳离子脂质是用于基因递送的有前途的试剂,并说明了用于脂质复合物发现的固相合成方法的潜力。
