Bile acid derivatives, processes for their preparation and use as pharmaceuticals Bile acid derivatives of the formula I W--X--G in which G is a bile acid radical, W is an active compound moiety of a medicament and X is a bonding member between a bile acid radical and active compound moiety, are outstandingly suitable for introducing active compounds into the enterohepatic circulation. The compounds I are absorbed and pass into the bloodstream. It is possible in this way, using the natural reabsorption of the bile acids, to achieve improved absorption of non-absorbable or poorly absorbable pharmaceuticals. W may be, for example, a peptide, an antibiotic, an antiviral substance, an anticancer agent, a hepatoprotective agent, an antihyperlipidemic, a diuretic, a hypotensive, a renin inhibitor, a substance for the treatment of cirrhosis of the liver or a substance for the treatment of diabetes. G is a bile acid radical in the form of the free natural or chemically modified acids, the esters and amides, the salt forms and forms derivatized on alcohol groups. X is a large number of intermediate members or, alternatively, a bond.
胆酸衍生物,其制备过程和用作药物的方法。公式I中的胆酸衍生物W--X--G,其中G是胆酸基团,W是药物中的活性化合物基团,X是胆酸基团和活性化合物基团之间的结合成员,非常适合将活性化合物引入肠肝循环中。化合物I被吸收并进入血液循环。通过利用胆酸的自然重吸收,可以以这种方式实现对不易吸收或吸收不良的药物的改善吸收。例如,W可以是肽,抗生素,抗病毒物质,抗癌剂,肝保护剂,降脂药,利尿剂,降压药,肾素抑制剂,用于治疗肝硬化或糖尿病的物质。G是自由的天然或化学修饰酸,酯和酰胺,盐形式和醇基衍生物形式的胆酸基团。X是许多中间成员或者是化学键。
