Synthesis of sulfated and unsulfated (glyco)peptide fragments of Hirudin P6 (a potent anticoagulant from the leech Hirudinaria manillensis) is described. The effect of O-glycosylation and tyrosine sulfation on thrombin binding and peptidolytic activity was investigated, together with the inhibition of fibrinogen cleavage.
