Synthesis and biological activity of a new anti-factor Xa pentasaccharide with a C-interglycosidic bond
摘要:
A mixed synthetic C, O-pentasaccharide 17 has been synthesized and shown to display an anti-factor Xa activity similar to that of the corresponding O-pentasaccharide 18. 17 represents the first example of a synthetic C-oligosaccharidic mimetic eliciting a significant biological response.

A synthetic polysaccharide including an antithrombin III binding domain consisting of a concatenation of five monosaccharides supporting a total of two carboxylic acid functions and at least four sulpho groups, said domain being directly bound at the non-reducing end by a thrombin binding domain including a concatenation of 10-25 monosaccharide units selected from hexoses, pentoses or deoxy sugars of which all the hydroxyl groups are etherified by a C1-6 alkyl group or esterified in the form of sulpho groups, as well as salts and particularly pharmaceutically acceptable salts thereof, are disclosed.
