摘要: The present invention aims to provide a cationic lipid that can be used as a nucleic acid delivery carrier, a lipid membrane structure using a cationic lipid, a nucleic acid-introducing agent using a cationic lipid, and a method of achieving nucleic acid introduction by using a nucleic acid-introducing agent containing a cationic lipid. A lipid membrane structure containing a cationic lipid represented by the formula (1)
wherein each symbol is as defined in the DESCRIPTION, is superior in the stability in blood and tumor accumulation property. A nucleic acid-introducing agent using the cationic lipid can achieve high nucleic acid delivery efficiency of nucleic acid to be delivered into the cytoplasm.摘要翻译: 本发明的目的在于提供可用作核酸递送载体的阳离子性脂质,使用阳离子脂质的脂质膜结构体,使用阳离子性脂质的核酸导入剂,以及使用阳离子脂质的核酸导入剂的使用方法 含有阳离子脂质的核酸引入剂。 包含由式(1)表示的阳离子脂质的脂质膜结构体,其中每个符号如说明书中所定义,在血液稳定性和肿瘤积聚性方面优异。 使用阳离子脂质的核酸引入剂可以实现待递送到细胞质中的核酸的高核酸递送效率。
