  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，其具有位于脂质基团（例如，疏水链）的中部或远端部位的一个或多个可生物降解的基团。这些阳离子脂质可以被纳入脂质颗粒中，用于传递活性剂，例如核酸。该发明还涉及包括中性脂质、能够减少聚集的脂质、本发明的阳离子脂质以及可选地固醇的脂质颗粒。脂质颗粒还可以进一步包含治疗剂，如核酸。

  The present invention relates to novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides, to facilitate the cellular uptake and endosomal escape, and to knockdown target mRNA both in vitro and in vivo. 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.
