Bipolar lipids are described which are able to form complexes with polyanions. The lipids comprise a cationic head linked to a hydrophobic backbone and a hydrophilic tail and are capable of self assembly to form stable complexes in aqueous solutions. The lipids are of particular use for the delivery of bioactive substances such as nucleic acids to cells in vitro and especially in vivo.
描述了一种能够与多聚阴离子形成复合物的双极脂质。该脂质由阳离子头部连接到疏水骨架和亲水尾部组成,能够自组装形成在水溶液中稳定的复合物。这种脂质特别适用于将生物活性物质如核酸传递到体外和体内的细胞中。
