摘要:
The invention aims at effectively utilizing a single-stranded nucleic acid copolymer, in particular, poly(adenylic acid-uridylic acid) and providing a drug composition having an antitumor effect. An example of the drug composition of the invention is one containing a lipid device, such as Lipofecting®, 3-O-(4-dimethylaminobutanoyl)-1,2-O-dioleylglycerol, 3-O-(2-dimethylaminoethyl)carbamoyl-1,2-O-dioleylglycerol, 3-O-(2-diethylaminoethyl)-carbamoyl-1,2-O-dioleylglycerol or 2-O-(2-diethyl-aminoethyl)carbamoyl-1,3-O-dioleylglycerol, and poly(adenylic acid-uridylic acid).
摘要:
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.
