The present invention provides ortho ester lipids and their derivatives that, upon certain pH conditions, undergo hydrolysis with concomitant or subsequent headgroup cleavage. These ortho ester lipids can advantageously be formulated into liposomes. The liposome formulations are useful in nucleic acid transfection and entrapment/delivery of conventional small molecules and therapeutic agents. Moreover, the liposomes comprising compounds of the present invention are useful as drug delivery vehicles.
本发明提供了骨架酯脂质及其衍生物,根据特定的pH条件,这些骨架酯脂质会与伴随或随后的头基裂解一起发生水解。这些骨架酯脂质可以有利地配制成脂质体。这些脂质体制剂在核酸转染以及传统小分子和治疗剂的包埋/输送中非常有用。此外,包含本发明化合物的脂质体用作药物输送载体非常有用。
