Use
Refludan was launched in Germany for heparin-associated
thrombocytopenia. Originally isolated from the saliva of leeches (Hirudo medicinalis),
the gene for recombinant hirudin was synthesized and expressed in Saccharomyces
cerevisiae. The isolated protein is 65 amino acids differing from the native protein by
the first two amino acids (Leu1 and Thr2) and Tyr63 is not sulfated, while it does retain
the three disulfide bonds. Refludan is a potent, specific and almost irreversible
inhibitor of thrombin with which it forms a 1:1 complex. The N-terminal domain binds
to the active catalytic site of thrombin, while the C-terminal end binds to the anion
binding exosite (fibrinogen binding cleft). It has several advantages over heparin: it
can inhibit thrombin bound to extracellular matrices, does not require antithrombin Ⅲ
as a cofactor, is not inhibited by activated platelet nor increases platelet activity, and is
a pure, single compound with a single mechanism of action. It is useful for myocardial
infarcts, unstable angia and cardiovascular events. Heparin treatment can be inhibited
by platelets activated by the Fc fragment of antibodies developed to the antigen of
heparin-platelet factor 4. A corresponding inactivation of Refuldan is not known.
