The present invention relates to a cationic lipid having one or more biodegradable groups located in the mid- or distal section of a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.
本发明涉及一种阳离子脂质,其一个或多个可生物降解基团位于阳离子脂质的脂质分子(如疏水链)的中段或远端。这些阳离子脂质可掺入脂质颗粒中,用于递送核酸等活性剂。本发明还涉及由中性脂质、能够减少聚集的脂质、本发明的阳离子脂质和可选的固醇组成的脂质颗粒。脂质微粒可进一步包括治疗剂,如核酸。
