The present invention provides lipids that are advantageously used in lipid particles for the in vivo delivery of therapeutic agents to cells. In particular, the invention
provides lipids having the following structure XXXIII, wherein:
R1 and R2 are each independently for each occurrence optionally substituted C10-C30 alkyl, optionally substituted C10-C30 alkenyl, optionally substituted C10-C30 alkynyl, optionally substituted C10-C30 acyl, or -linker-ligand; R3 is H, optionally substituted C1-C10 alkyl, optionally substituted C2-C10 alkenyl, optionally substituted C2-C10 alkynyl, alkylhetrocycle, alkylphosphate, alkylphosphorothioate, alkylphosphorodithioate, alkylphosphonates, alkylamines, hydroxyalkyls, ω-aminoalkyls, ω-(substituted)aminoalkyls, ω-phosphoalkyls, ω-thiophosphoalkyls, optionally substituted polyethylene glycol (PEG, mw 100-40K), optionally substituted mPEG (mw 120-40K), heteroaryl, heterocycle, or linker-ligand; and E is C(O)O or OC(O).
本发明提供了可用于脂质颗粒的脂质,这些脂质可用于向细胞体内输送治疗剂。特别是,本发明
提供具有以下结构 XXXIII 的脂质,其中:
R1 和 R2 在每次出现时各自独立地为任选取代的 C10-C30 烷基、任选取代的 C10-C30 烯基、任选取代的 C10-C30 炔基、任选取代的 C10-C30酰基或-连接配体;R3 是 H、任选取代的 C1-C10 烷基、任选取代的 C2-C10 烯基、任选取代的 C2-C10 烷炔基、烷基己环、烷基磷酸酯、硫代磷酸烷基酯、二硫代磷酸烷基酯、烷基膦酸盐、烷基胺羟基烷基、ω-氨基烷基、ω-(取代)氨基烷基、ω-硫代磷酸烷基、ω-硫代磷酸烷基、任选取代的聚乙二醇(PEG,mw 100-40K)、任选取代的 mPEG(mw 120-40K)、杂芳基、杂环或连接配体;E 是 C(O)O 或 OC(O)。
