Polymers and oligomers of bile acid derivatives, process for their preparation and their use as pharmaceuticals |
摘要 |
Polymeric and oligomeric bile acids are described which can be prepared by polymerization of monomeric bile acids of the formula I G-X-A(I) in which G, X and A have the given meanings or by copolymerization with a monomer of the formula IV <IMAGE>s, or by copolymerization with N-vinylpyrrolidone or its derivatives, and/or by copolymerization with ethylenically unsaturated dicarboxylic anhydrides and ethylenically unsaturated dicarboxylic acids each having 2 to 6 carbon atoms; their esters or half esters, alkyl esters having 1-6 carbon atoms, cycloalkyl esters having 5 to 8 carbon atoms, benzyl esters or phenyl esters being understood as esters. They can be used as pharmaceuticals, foodstuff additives, formulation auxiliaries and detergents.
