Protease inhibitor of the coagulation cascade isolated from Dysidea sponge

摘要

The present invention is directed toward a composition comprising a compound isolated from Dysidea species sponges that is capable of inhibiting serine proteases of the coagulation cascade. In particular, this composition inhibits the TF/VIIa complex of the coagulation cascade. The invention is also directed toward methods employing this composition as a part of anticoagulant therapy.
