    • The invention relates to a tetraether lipid with the general formula (I) in which R1 is a modified or unmodified gulose radical or an oxidation product of said gulose, and R2 is hydrogen, modified or unmodified phosphoglycerine or an oxidation product thereof. It also relates to the use of a tetraether lipid according to the invention and liposomes which contain 0.1 to 100 % by weight, in relation to the whole lipid, of the tetraether lipid according to the invention. Conventional liposomes have a low level of stability in storage and are acid-labile. The use thereof for oral administration of pharmaceuticals which should not be released until they are in the duodenum is therefore not possible. In contrast, liposomes containing the tetraether lipid according to the invention are acid-stable and can therefore move easily through the stomach into the small intestine, and cause resorption therein of active ingredients which are contained in said liposomes and cannot usually be absorbed into the blood stream after oral administration.
    • 本发明涉及具有通式(I)的四醚,其中R 1是指经修饰的或未经修饰的Guloserest或这样古洛糖和R的氧化产物2为氢,改性或未改性的磷酸甘油或其氧化产物可以是,使用根据本发明的Tetraetherlipides的以及脂质体 本发明Tetraetherlipides的含有0.1〜100重量%,基于总脂质,包括在内。 常规脂质体具有低的贮存稳定性和是酸不稳定的。 因此它们对于那些酸敏感药物的口服给药使用仅在十二指肠被释放是不可能的。 与此相反,根据包含四醚的本发明的脂质体是酸稳定的,因此可以通过胃通无阻地进入小肠并获得困在其中的物质,其通常不能进入血流口服给药后,在那里吸收。
