The invention aims at providing a device comprising lipids that act like the so-called cationic liposome and are reduced in toxicity and the lipids as the constituent of the device. The invention compounds are exemplified by 3-0-(4-dimethylaminobutanoyl)-1,2-0-dioleylglycerol, 3-0-(2-dimethylaminoethyl)carbamoyl-1,2-0-dioleylglycerol, 3-0-(2-diethylaminoethyl)carbamoyl-1,2-0-dioleylglycerol, and 2-0-(2-diethylaminoethyl)-carbamoyl-1,3-0-dioleylglycerol. The device comprises these lipids and phospholipids. The device enables, when administered together with, for example, a double-stranded RNA, the RNA to migrate to the action site safely.
本发明旨在提供一种由脂质组成的装置,这种脂质的作用类似于所谓的阳离子脂质体,并且毒性较低,脂质是该装置的组成成分。本发明化合物的例子有 3-0-(4-二甲基
氨基丁酰基)-1,2-0-二油基
甘油、3-0-(2-二甲基
氨基乙基)
氨基甲酰基-1,2-0-二油基
甘油、3-0-(2-
二乙基氨基乙基)
氨基甲酰基-1,2-0-二油基
甘油和 2-0-(2-
二乙基氨基乙基)
