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,其制备方法及用作药物的用途。公式I中的胆酸衍生物为W--X--G,其中G为胆酸基团,W为药物的活性化合物部分,X为胆酸基团和活性化合物部分之间的连接成员,非常适合将活性化合物引入肠肝循环中。这些化合物I被吸收并进入血液循环。通过利用胆酸的自然重吸收,可以实现对非可吸收或难吸收药物的改善吸收。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,治疗肝硬化的物质或治疗糖尿病的物质。G是以自然或化学修饰的酸,酯和酰胺,盐形式以及在醇基团上衍生化形式的胆酸基团。X是大量的中间成员或者是一个键。
