Desmoteplase
From Wikipedia, the free encyclopedia
Desmoteplase is a chemical in the saliva of vampire bats. It activates plasminogen to the serine protease, plasmin. Plasmin acts by breaking down fibrin blood clots. When a vampire bat bites its victim, it secretes an enzyme that prevents the blood from clotting. The enzyme is called DSPA (Desmodus rotundus saliavary plasminogen activator) and scientists are using DSPA as stroke and heart attack medication. Discovered by Dr. Robert Medcalf at Box Hill Hospital.
