Synthetic pentadeca-, heptadeca- and nonadecasaccharides, comprising an ant
ithrombin III (AT III) binding pentasaccharide prolonged at the non-reducin
g end by a thrombin binding domain have been obtained. The pentadecasacchar
ide is the shortest oligosaccharide able to catalyse thrombin inhibition by
AT III. The nonadecasaccharide is a more potent thrombin inhibitor than st
andard heparin. (C) 1999 Published by Elsevier Science Ltd. All rights rese
