Description

DODAP (1,2-Dioleoyl-3-dimethylammonium-propane) is a cationic lipid used as the lipid nanoparticle (LNP) with the pKa value of 5.59 [1]. DODAP remains largely neutral at physiological pH and becomes protonated under acidic conditions, such as those encountered during endosomal trafficking[2]. The larger lipid-water interfacial area provided by the DODAP self-assemblies at pH≤4.5 allowed for an adequate encapsulation efficiency of LL-37, favouring the formation of vesicles in a concentration-dependent manner[3]. DODAP has been widely used for efficient in vivo targeted gene delivery and possesses spleen specificity[4].

DODAP (1,2-Dioleoyl-3-dimethylammonium-propane)是一种阳离子脂质,用作脂质纳米颗粒(LNP)的组分,pKa值为5.59[1]。DODAP在生理pH值下基本保持中性,在内体运输等酸性条件下会质子化[2]。在pH≤4.5时,DODAP自组装体提供的较大脂质-水界面面积使得LL-37具有足够的包封效率,并以浓度依赖性方式促进囊泡的形成[3]。DODAP已被广泛用于高效的体内靶向基因递送,并具有脾脏特异性[4]
