Abstract

Lav-molekylvekt heparinderivater og salter derav er fremstilt ved behandling av et kvaternært ammoniumsalt av et heparin, opplest i et heterosyklisk organisk opplesningsmiddel eller i et aprotisk opplesningsmiddel, ned et alkylerende middel, som har fra 6-30 karbonatomer, ved en temperatur på tilnærmet 20°-60°C, i en forlenget tidsperiode, og behandling av det resulterende reaksjonsprodukt, ved en temperatur på tilnærmet 5e-120°C, med en uorganisk eller organisk base, såsom et alkalisk hydroksid, i vandig opplesning, og isolering av de oppnådde heparinderi- vater i sin frie form eller som et alkalisk salt derav. Heparinderivatene oppnådd i henhold til fremgangsmåten i den foreliggende oppfinnelse utgjør en blanding av for det meste depolymeriserte produkter med molekylvekter innenfor et trangt område. Disse produkter er nyttige som antitrombotiske midler.Low molecular weight heparin derivatives and salts thereof are prepared by treating a quaternary ammonium salt of a heparin, dissolved in a heterocyclic organic solvent or in an aprotic solvent, down an alkylating agent having from 6-30 carbon atoms at a temperature of approximately 20 ° -60 ° C, for an extended period of time, and treating the resulting reaction product, at a temperature of approximately 5e-120 ° C, with an inorganic or organic base, such as an alkaline hydroxide, in aqueous solution, and isolating the obtained heparin derivatives in their free form or as an alkaline salt thereof. The heparin derivatives obtained according to the process of the present invention comprise a mixture of mostly depolymerized products with molecular weights within a narrow range. These products are useful as antithrombotic agents.
