Fradafiban binds to the human platelet GP IIbIIIa complex with a Kd value of 148 nM. Fradafiban is a non-polypeptide platelet glycoprotein IIbIIIa antagonist.
AR-H067637 is a rapid-binding, reversible and potent (inhibition constant K(i) = 2-4 nM), competitive inhibitor of thrombin, as well as of thrombin bound to fibrin (clot-bound thrombin) or to thrombomodulin. The total amount of free thrombin generated in
