    摘要: The present invention provides novel phosphonic acid-based cationic lipids of the general structure: or a salt, or solvate, or enantiomers thereof wherein; (a) R1 is a lipophilic moiety; (b) R2 is a positively charged moiety; (c) R3 is a lipophilic moiety of 1 to about 24 carbon atoms, a positively charged moiety, or a negatively charged moiety; (d) n is an integer from 0 to 8; (e) X− is an anion or polyanion; (f) Y is N or 0, and (g) 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.
