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.
