Definitions
- the present invention relates to low molecular weight heparins, more generally mixtures of heparinoid-derived polysaccharides, which have at least one covalent bond with biotin or a biotin derivative, as well as their method of preparation, pharmaceutical compositions containing them and their use in therapy.
- Heparin is a mixture of sulfated mucopolysaccharides of animal origin, with a molecular weight of around 15,000 Dalton (Da), used in particular for its anticoagulant and antithrombotic properties. Heparin, however, has drawbacks that limit the conditions of its use. In particular, its important anticoagulant activity (especially its high anti-Ha factor activity) can cause haemorrhages (Seminars in Thrombosis and Hemostasis, Vol 5, sup 3, 1999).
- Heparins of low molecular weight for example between 3000 and 7000 Da and more particularly between 3500 and 5500 Daltons, especially obtained by basic depolymerization of heparin esters and currently marketed, such as enoxaparin, also exhibit anti-inflammatory activity. -factor lia important. Heparin derivatives are known for these undesirable hemorrhagic side effects.
- the goal is to restore or maintain the fluidity of the blood while avoiding causing hemorrhage. It is well known that, for any accidental cause, hemorrhage may occur in a patient under treatment. It may also be necessary to intervene surgically in a patient under antithrombotic treatment.
- anticoagulants can be used in high doses to prevent blood clotting, and it would be useful to be able to neutralize them at the end of the procedure.
- the need is felt to have agents Neutralizable antithrombotic agents to stop anticoagulant activity at any time.
- Neutralizable antithrombotic agents such as biotinylated synthetic polysaccharides
