Abstract

Cette invention concerne des amphiphiles cationiques qui sont des esters d'alkyle ou d'alcoxyalkyle O-phosphate de composés zwittérioniques de diacylphosphatidyle tels que le phosphatidylcholine ou le phosphatidyle éthanolamine. Ces amphiphiles peuvent être utilisés comme véhicules pour transporter des macromolécules à l'intérieur des cellules.
