Effect of O-glycosylation and tyrosine sulfation of leech-derived peptides on binding and inhibitory activity against thrombin
Basic science published in Chem Commun (2011)
Abstract
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.

Резюме
Synthesized sulfated and glycosylated Hirudin P6 fragment peptides show tyrosine sulfation enhances thrombin binding.
Почему это важно для гирудотерапии
This study synthesized sulfated and unsulfated (glyco)peptide fragments of Hirudin P6—a potent anticoagulant from the leech Hirudinaria manillensis—and examined the effect of O-glycosylation and tyrosine sulfation on thrombin binding, peptidolytic activity, and inhibition of fibrinogen cleavage. This is relevant to ASH because it clarifies structure–activity relationships of a leech-derived thrombin inhibitor, informing how post-translational modifications modulate anticoagulant potency. The caveat is that this is an in-vitro biochemical/synthetic peptide study with no whole leech, no secretome, and no clinical or animal data, so relevance to actual hirudotherapy is indirect and mechanistic only.
