Anticoagulant sodium alginate sulfates and their mussel

In this work we synthesized novel sodium alginate sulfates (SASs) with different sulfation degrees which had similar chemical structure and bioactivity as those of heparin Blood clotting time tests indicated that the heparin-mimetic SASs exhibited excellent and sulfation-degree-dependent anticoagulant act 2016 Journal of Materials Chemistry B Hot Papers
