The present invention relates to a cationic lipid having one or more biodegradable groups located in 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,其中在阳离子脂质的脂质部分(例如,疏水链)中具有一个或多个可生物降解的基团。这些阳离子脂质可以掺入脂质粒子中,用于递送一种活性剂,例如核酸。本发明还涉及包含中性脂质、能够减少聚集的脂质、本发明的阳离子脂质以及可选的甾醇的脂质粒子。脂质粒子还可以进一步包括治疗剂,例如核酸。
