Ph-sensitive cationic lipids, and liposomes and nanocapsules containing the same
摘要:
The invention suggests a pH-sensitive cationic lipid with a pKa value between 3.5 and 8, according to the general formula cation-spacer-Y-spacer-X-lipid, wherein Y and X represent linking groups. Furthermore, liposomes are described, which liposomes include said optionally cationic lipids.
