  • Low anticoagulant heparins
    Patent number: 9480701
    Abstract: The present invention relates to a chemically modified heparin, with an antifactor II activity of less than 10 IU/mg, an antifactor Xa activity of less than 10 IU/mg and an average molecular weight (Mw) between about 6.5 and 9.5 kDa. Also disclosed is a method of preparing the heparin and its medical use, including treatment of malaria.

  • Process for preparing high purity low molecular weight heparins
    Publication number: 20050049222
    Abstract: The present invention relates to a process for preparing high purity low molecular weight heparins with average molecular weight of between 2000 and 10000 daltons by the stages of forming an intermediate heparin benzethonium salt, from this latter a water soluble heparin ester, and of subjecting said ester to depolymerisation with bases to form said low molecular weight heparins, characterised in that at least said stage of heparin benzethonium salt formation is carried out on an inert adsorbent solid matrix of filtering material, or filter-aid, said low molecular weight heparins being finally subjected to a purification stage by reducing the impurities present with borohydride.
