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.

(EN) The invention concerns novel compounds useful as agents for transferring nucleic acids into cells. Said novel compounds are more particularly related to the lipopolyamine family, and comprise at least a cyclic amidine function. They are useful for transfecting nucleic acids of interest into different cell types, $i(in vitro) as well as $i(in vivo) or $i(ex vivo).(FR) La présente invention concerne de nouveaux composées utiles comme agents de transfert d'acides nucléiques dans les cellules. Ces nouveaux composés sont plus particulièrement apparentés à la famile des lipopolyamines, et comportent au moins une fonction amidine cyclique. Ils sont utiles pour la transfection des acides nucléiques d'intérêt dans différents types cellulaires, aussi bien $i(in vitro) que $i(in vivo) ou $i(ex vivo).
