The invention provides a cationic lipid comprising:
(i) one head group, comprising one or more amino acids, in which at least one amino acid has a side chain that comprises a cationic moiety or a cationic precursor;
(ii) a linking moiety of formula (5):
—(HNR5)2NC(O)R3C(O)— (5),
wherein:
each R5 is independently an optionally substituted C1-4 alkylene moiety; and
R3 is an optionally substituted alkylene or alkenylene moiety; and
(iii) two lipophilic moieties,
wherein the head group and each of the lipophilic moieties are connected to the linking moiety through amide linkages.
本发明提供了一种阳离子脂质,包括:(i)一个头基团,包括一个或多个
氨基酸,其中至少一个
氨基酸具有包含阳离子基团或阳离子前体的侧链;(ii)一个连接基团,其
化学式为(5):—(HNR5)2NC(O)R3C(O)— (5),其中:每个R5独立地是一个可选取代的C1-4烷基链;R3是一个可选取代的烷基或烯基链;以及(iii)两个疏
水基团,其中头基团和每个疏
水基团通过酰胺键连接到连接基团上。
