Anistreplase cleaves the Arg/Val bond in plasminogen to form plasmin. This in turn leads to the degradation of blood clots. It is a complex of purified human plasminogen and bacterial streptokinase that has been acylated to protect the enzyme's active site. When the drug is administered, the acyl group gets hydrolyzed, thereby freeing the activator complex. It converts plasminogen to plasmin, which in turn degrades fibrin (blood clots) to fibrin split products.
