    The structures of two mimetic inhibitor complexes of human alpha-thrombin have been determined by X-ray crystallography. One mimics a beta-turn with a bicyclic ring system; the other mimics two different active-site binding modes. The beta-turn mimetic is used to approximate a turn found in the conformation of fibrinopeptide A, which is catalytically released by thrombin in the activation of fibrinogen to fibrin. The binding of the second mimetic is a hybrid between normal substrate and the abnormal binding of the potent natural leech inhibitor hirudin. The binding of the beta-turn mimetic is tenuous, because it is like a substrate, while that of the substrate-hirudin hybrid is that of a tenacious inhibitor (which it is). Structurally retrospect modifications for rational design and improvement of both mimetic inhibitors are proposed.
