  • N,O-sulphated heparosans and pharmaceutical compositions containing them
    Patent number: 5550116
    Abstract: The invention relates to N,O-sulphated heparosans consisting of chains or of a mixture of chains of molecular mass between 1500 and 15,000 Da, characterized by a repeated disaccharide structure of formula I: ##STR1## in which: E represents an acetyl group in 0 to 80% of the disaccharide units of the said N,O-sulphated heparosan, and a sulphate group and possibly a hydrogen atom in the remaining disaccharide units,G represents a hydrogen atom and a sulphate group, and the pharmaceutically acceptable salts of thesaid N,O-sulphated heparosans. The heparosans are useful as anticoagulants.
