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.

摘要:
Provided herein are novel cationic lipids, compositions comprising the cationic lipids, and methods of using the cationic lipids. In some claims, the cationic lipids have cytotoxic activity and can be used alone or in combination with a cytotoxic bioactive compound to kill a cell. In some of these claims, the cationic lipid enhances the cytotoxic activity of the cytotoxic bioactive compound. Methods for treating a subject afflicted with a disease or unwanted condition are provided, wherein the method comprises administering a delivery system comprising a novel cationic lipid to the subject. The invention further provides methods for making delivery systems comprising the novel cationic lipids of the invention.
摘要:
The present invention relates to acylguanidine derivatives of formula (I) in which R?1, R2, R4, R5, R6¿, A, m and n have the meanings indicated in the patent claims, their physiologically tolerable salts and their prodrugs. The compounds of formula (I) are valuable pharmaceutical active ingredients. They are vitronectin receptor antagonists and inhibitors of bone resorption by osteoclasts and are suitable, for example, for the therapy or prophylaxis of diseases which are caused at least partially by an undesired extend of bone resorption, for example of osteoporosis. The invention furthermore relates to processes for the preparation of compounds of formula (I), their use, in particular as pharmaceutical active ingredients, and pharmaceutical preparations comprising them.
摘要:
