摘要：
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 (I) 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； E is 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, aryl, heteroaryl, cyclic or heterocycle； and, Q is H, alkyl, ω-aminoalkyl, ω-(substituted)aminoalky, ω-phosphoalkyl or ω-thiophosphoalkyl.La presente invención se refiere a un lípido de la fórmula XXXVIII: o una sal o isómero, en donde E es (O)(CO)N(Q)； Q es H； R1 y R2 son cada uno independientemente para cada aparición alquilo de C10-C30；Rx es H； R3 es alquilo de C1-C10 opcionalmente sustituido, ?-aminoalquilo, o ?-aminoalquilo(sustituto)； y n es 1.
