Conformational activation of antithrombin is a critical mechanism for the inhibition of factor Xa, a proteinase of the blood coagulation cascade, and is typically achieved with heparin, a polyanionic polysaccharide clinically used for anticoagulation.

Recently, we designed (-)-epicatechin sulfate (ECS), the first small nonsaccharide molecule, as an activator of antithrombin for the accelerated inhibition of factor Xa, a key proteinase of the coagulation cascade (Gunnarsson, G.

New non-sugar, small, sulfated molecules, based on our de novo rationally designed activator (-)-epicatechin sulfate (ECS), were investigated to bind and activate antithrombin, an inhibitor of plasma coagulation enzyme factor Xa.

J Biol Chem. 2008 Oct 17;283(42):28115-24. Epub 2008 Jul 31.


These antithrombin-binding chains contain more than 6% 3-O-sulfated glucosamine residues, convey an anticoagulant activity of 2.5 IU/ml to human follicular fluid, and have an anti-Factor Xa specific activity of 167 IU/mg.
