The development of thrombolytic agent could provide invaluable progress for antithrombotic therapy. In this paper, we reported the cloning, purification and biochemical characterization of AnxB1ScuPAFap, a thrombus-ditargeting chimera composed of annexin B1, low molecular single-chain urokinase (ScuPA-32K) and fibrin-adherent peptide (dodecapeptide, Fap). In vitro test showed that, the chimera was a thrombolytic agent with anticoagulant activity and thrombus-ditargeting with the activated-platelet membrane binding and fibrin clot binding activity. Compared to urokinase, the chimera had less reperfusion time, higher reperfusion ratio, and less bleeding effects on coronary thrombolysis by clot lysis assay in dogs. Thus, the chimera appeared to be suitable for thrombolytic therapy of thrombus diseases.
