  New synthetic heparin mimetics able to inhibit thrombin and factor Xa

  摘要：

  Synthetic pentadeca-, heptadeca- and nonadecasaccharides, comprising an antithrombin III (AT III) binding pentasaccharide prolonged at the non-reducing end by a thrombin binding domain have been obtained. The pentadecasaccharide is the shortest oligosaccharide able to catalyse thrombin inhibition by AT III. The nonadecasaccharide is a more potent thrombin inhibitor than standard heparin.

  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.

  Kinetic studies of thrombin inhibition by antithrombin in the presence of heparin have shown that thrombin binds to heparin in a preformed heparin - antithrombin complex. To study the relative position of the thrombin binding domain and the antithrombin binding domain on a heparin molecule we have designed and synthesized heparin mimetics which structurally are very similar to the genuine polysaccharide. Their inhibitory properties with respect to factor Xa and thrombin provide experimental evidence that in heparin the thrombin binding domain must be located at the nonreducing end of the antithrombin binding domain to observe thrombin inhibition. As expected, factor Xa inhibition is not affected by elongation of the antithrombin binding pentasaccharide sequence, regardless of the position in which this elongation takes place.
