The present invention provides novel carbamate-based cationic lipids of the general structure:
1
or a salt, or solvate, or enantiomers thereof wherein; (a) R
1
, is a lipophilic moiety; (b) R
2
is a positively charged moiety; (c) n is an integer from 1 to 8; (d) X
− is an anion or polyanion; and (e) m is an integer from 0 to a number equivalent to the positive charge(s) present on the lipid. The present invention further provides compositions of these lipids with polyanionic macromolecules, methods for interfering with protein expression in a cell utilizing these compositions and a kit for preparing the same.
本发明提供了新型基于碳酸酯的阳离子脂质,其一般结构如下:1或其盐、溶剂化物或对映异构体,其中:(a) R1是一个亲脂性基团;(b) R2是一个带正电荷的基团;(c) n是一个从1到8的整数;(d) X-是一个阴离子或多阴离子;(e) m是一个从0到等于脂质上正电荷数目的整数。本发明还提供了这些脂质与多阴离子大分子的组合物、利用这些组合物干扰细胞中蛋白质表达的方法以及用于制备该组合物的试剂盒。
