Introduction of cyclic guanidines into cationic lipids for non-viral gene delivery
摘要:
In order to study the impact of chemical modifications of lipopolyamines on their gene delivery properties, we have introduced cyclic guanidines into the polyamine moiety. These lipopolyamino-cycloguanidines can be easily obtained by reacting polyamines with 2-methylmercapto-2-imidazolinium iodide or 2-methylmercapto tetrahydropyrimidinium iodide. These lipopolyamino-cycloguanidines constitute a novel family of cationic lipids. (C) 2000 Elsevier Science Ltd. All rights reserved.

Synthesis, Activity, and Structure−Activity Relationship Studies of Novel Cationic Lipids for DNA Transfer
synthetic method on solid support allowed easy access to unsymmetrically monofunctionalized polyamine buildingblocks of variable geometries. These polyamine buildingblocks were introduced into cationic lipids. To optimize the transfection efficiency in the novel series, we have carried out structure-activity relationship studies by introduction of variable-length lipids, of variable-length linkers between
