We describe the synthesis and characterization of a type of pH-sensitive pentaerythritol phospholipids, using a trialkoxybenzylidene acetal as the acid-labile moiety. This lipid was prepared by an eight-step synthesis via a latentiation strategy. Liposomes were prepared via the thin film extrusion method. The changes of liposomal sizes were measured by dynamic light scattering. Content release rates
我们描述了使用三烷氧基亚苄基乙缩醛作为酸不稳定部分,对一类pH敏感的季戊四醇磷脂的合成和表征。该脂质通过潜在化策略通过八步合成制备。脂质体通过薄膜挤出法制备。通过动态光散射测量脂质体大小的变化。通过使用钙黄绿素荧光去猝灭测定来监测脂质体的含量释放速率随pH的变化。这些结果表明,这种新的脂质体系统能够在中等酸性条件下释放其内含物。最后,针对三种细胞系进行了体外细胞毒性测定,表明这种磷脂是低毒性的。
