| Research Abstract |
A new synthetic nonadecapeptide (SP) corresponding to Glu22-Leu40 of staphylokinase molecule bound to plasminogen (Plg) and enhanced the activation of Plg by Plg activator (PA). This binding was completely inhibited by synthetic peptide corresponding to C-terminal region of plasmin B-chain. SP binds to Glu-Plg, and induces structural changes of Glu-Plg. When SP was administrated in mouse thrombosis model, earlier recanalization was observed than in mice with vehicle administration. Thus, SP enhanced Plg activation and induced effective thrombolysis.
