摘要: The present invention relates to a process for the preparation of a polysaccharide composed of D-xylose units of formula (III) linked together via beta 1,4 glycosidic bonds wherein R1 is hydrogen or acetyl, R2 is hydrogen, acetyl or a 4-O-methyl glucuronic acid unit, wherein, when R2 is a 4-O-methyl glucuronic acid unit, the R1 group on the same saccharide unit is defined as G, wherein G is hydrogen or acetyl, and wherein the sugar unit at the reducing end of sun such polysaccharide is xylose, lyxose or xylulose, said process comprising the following steps: selective deacetylation of xylan extracted from beech wood; and isomerization of the selectively deacetylated xylan achieved in step or the following steps: isomerization of xylan extracted from beech wood; and selective deacetylation of isomerized xylan achieved in step. The process is useful for the preparation of pentosan polysulfate or pharmaceutically acceptable salts thereof for pharmaceutical use.

摘要: The document describes a process for the preparation of N-Acyl-Phosphatidyl-Ethanolamine of formula (I) on an industrial scale, In which R1, R2 and R3 are, independently from each other, saturated, monounsaturated or polyunsaturated acyls C10-C30, pure or mixed together, and X=OH or OM, where M=alkaline metal or alkaline earth, ammonium or alkylammonium. The process in question allows the conversion of lecithin of synthetic or natural origin into N-Acyl-Phosphatidyl-Ethanolamine of formula (I) of high purity, using a limited molar excess of the reagent N-acyl-ethanolamine, where the acyl is as defined above for the formula (I) through reaction of transphosphatidylation in the presence of the enzyme phospholipase D and in conditions suitable for production on an industrial scale.
