    • The invention relates to sulphated polysaccharides which have the general structure of the constituent polysaccharides of heparin and which have a molecular weight of less than 8000 Daltons, comprising two antithrombin III-binding hexasaccharide sequences corresponding to formula (I) in which: R1 represents an OH group when the hexasaccharide of formula (I) is located at the reducing end of the polysaccharide, or else R1 represents a bond with another saccharide unit of said polysaccharide; R2 represents a hydrogen atom when the hexasaccharide of formula (I) is located at the non-reducing end of the polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit of said hexasaccharide is a double bond, or else R2 represents a bond with another saccharide unit of said polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit is a single bond. Preparation thereof, use thereof as antithrombotic medicaments, and also use thereof in a method for analyzing a sample of a heparin derivative.
    • 本发明涉及具有肝素成分多糖的分子量小于8000道尔顿的硫酸化多糖,其包含对应于式(I)的两种抗凝血酶III结合六糖序列,其中:R1表示OH 当式(I)的六糖位于多糖的还原端时,或者R1表示与所述多糖的另一个糖单元的键; 当式(I)的六糖位于多糖的非还原端时,R2表示氢原子,在这种情况下,所述六糖的第一糖单元的碳原子4和5之间的键是双键,或 否则R2表示与所述多糖的另一个糖单元的键,在这种情况下,第一糖单元的碳原子4和5之间的键是单键。 其制备方法,作为抗血栓药物的用途,以及其在分析肝素衍生物样品的方法中的应用。
