Abstract[English]
Disclosed are imidazolium-based cationic lipid useful for non-viral delivery of nucleic acids. These imidazolium-based cationic lipid that can be formulated into lipid nanoparticle and encapsulated nucleic acid, such as small interfering RNA (siRNA) and messenger RNA (mRNA). The disclosure not only provides efficient siRNA delivery and excellent gene silencing, but also able to mediate mRNA translation to produce proteins of interest.[French]
L'invention concerne un lipide cationique à base d'imidazolium utile pour l'administration non virale d'acides nucléiques. Ces lipides cationiques à base d'imidazolium peuvent être formulés sous forme de nanoparticule lipidique et sous forme d'acide nucléique encapsulé, tel qu'un petit ARN interférent (ARNsi) et un ARN messager (ARNm). La divulgation concerne non seulement une administration efficace d'ARNsi et un excellent silençage génique, mais est également apte à médier la traduction d'ARNm pour produire des protéines d'intérêt.
