摘要:
The invention relates to linker-modified bile acid derivatives of the formula I: ##STR1## wherein the radicals X.sup.1, X.sup.2, X.sup.3 and Y and n are as defined in the claims, and to a process for their preparation. The compounds according to the invention are therapeutically active and are thus suitable as drugs, especially as hypolipldemics. The invention further relates to the use of the bile acid derivatives according to the invention as drugs.
摘要:
Bile acid derivatives of the formula IW--X--Gin 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 entercepatic 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.

Process for the preparation of 3.beta.-aminocholanic acid derivativesA process for the preparation of 3.beta.-aminocholanic acid derivatives of the formula II ##STR1## wherein R(1), R(2) and R(3) have the meanings given, starting from the corresponding 3.beta.-hydroxycholanic acid esters, is described.
摘要:
Bile acid derivatives of the formula IZ(X--GS)nin which GS, X, Z and n have the meanings indicated in the specification, and a process for the preparation of these compounds are described. The compounds are pharmacologically active and can, therefore, be used as pharmaceuticals, in particular as a hypolipidemic.
摘要:
The invention relates to bile acid derivatives of the formula IG1--X--G2 (I)in whichG1 and G2 are bile acid radicals or modified bile acid radicals in the form of the free acids, the esters or amides, the salt forms and also the forms derivatized on the alcohol groups andX is a bridge group or a single covalent bond, it being possible for G1 and G2 to be optionally bonded via X.The compounds according to the invention have a high affinity for the specific bile acid transport system of the small intestine and inhibit bile acid absorption in a concentration-dependent and competitive manner.
