用于递送治疗剂的脂质和组合物
摘要：
本发明提供了有利地用于将治疗剂体内递送至细胞的脂质颗粒的脂质。具体地，本发明提供了具有下列结构(I)的脂质，其中R1和R2在每一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–连接体-配体；R3为氢、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炔基、烷基杂环、烷基磷酸酯、烷基硫代磷酸酯、烷基二硫代磷酸酯、烷基膦酸酯、烷基胺、羟烷基、ω-氨烷基、ω-(取代的)氨烷基、ω-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、杂环或连接体-配体；E为O、S、N(Q)、C(O)、N(Q)C(O)、C(O)N(Q)、(Q)N(CO)O、O(CO)N(Q)、S(O)、NS(O)2N(Q)、S(O)2、N(Q)S(O)2、SS、O＝N、芳基、杂芳基、环或杂环；以及Q为氢、烷基、ω-氨烷基、ω-(取代的)氨烷基、ω-磷酸烷基或ω-硫代磷酸烷基。
摘要（英）：

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 formula (I) 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, alky lhetro cycle, alkylphosphate, alkylphosphorothioate, alkylphosphorodithioate, alkylphosphonates, alkylamines, hydroxyalkyls, -aminoalkyls, - (substituted)aminoalkyls, -phosphoalkyls, -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).
