Process for the production of polyvalent, physiologically degradable carbohydrate receptor blockers by enzymatic glycosylation and their use for the production of carbohydrate components

摘要

The invention relates to a process for producing polyvalent polymer-based carbohydrate receptor blockers which in vivo do not, either in their complete form or when broken down, provoke intolerance reactions. The carbohydrate side chain of the receptor blocker is built up directly on the biodegradable polymer by enzymatic glycolisation reactions in aqueous buffer systems and homogenous phase; the yields of these glycolisation reactions are considerably better than those of known processes, generally progress quantitatively and the accumulation densities are markedly increased. Also proposed is a process for producing free oligosaccharides using the carbohydrate receptor blockers produced according to the invention.
