  • Publication number: 20230136745
    Abstract: The invention relates to an anti-thrombotic molecule having both anti-platelet and anti-coagulant (APAC) activity and, in particular, its use as a medicament to prevent and/or treat heparin-induced thrombocytopenia (HIT) type I or II; and/or heparin-induced thrombocytopenia and thrombosis (HITT); and/or heparin-independent thrombocytopenia autoimmune HIT (aHIT); and/or vaccine-induced thrombocytopenia and thrombosis (VITT). The invention has use in both the medical and veterinary industries.

  • Patent number: 8415324
    Abstract: Heparin-like compounds inhibit collagen-induced platelet aggregation in flowing whole blood. The compounds share properties displayed by native mast-cell derived heparin proteoglycans (HEP-PG) and/or heparin glycosaminoglycan (HEP-GAG) molecules. The compounds are useful in prevention and treatment of severe vascular disorders including arterial thrombosis.

  • Patent number: 7504113
    Abstract: The present invention is related to heparin-like compounds characterized by their capacity of inhibiting collagen-induced platelet aggregation in flowing whole blood and their use for prophylactic treatment of arterial thrombosis associated with vascular or microvascular injury and interventions. Said properties are related to a high coupling density of negatively charged heparin or heparin-like glycosaminoglycan molecules, present in multiple heparin or heparin-like glycosaminoglycans as well as in proteoglycans containing said multiple heparin or heparin-like glycosaminoglycans or lower-molecular-weight heparin or heparin-like glycosaminoglycans connected directly or through spacer/linker molecules to globular core molecules. Heparin-like compounds, with said properties are obtainable from mammalian mast cells, by tissue extraction or cell cultivation.
