Abstract

See full text

The invention provides a class of sucrose ester based cationic lipids and preparation method thereof. The vector prepared using the cationic lipid can be used to deliver nucleic acid. The sucrose ester based cationic lipid is prepared by using a chemical synthesis method in the invention, wherein the synthesis method is simple, and has a relatively high product yield. A composition, including suspension, emulsion, micelle and liposome and the like, can be prepared by mixing the sucrose ester based cationic lipid compound of the invention with a co-lipid. Sucrose ester based cationic lipid complex can be prepared by using the said composition and nucleic acid, which has advantages such as simple preparation, low toxicity and high transfection efficiency, and is a novel and highly efficient gene vector.
