Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.

Tissue-type plasminogen activator. Tissue-type plasminogen activator, short name tPA, is a protein that facilitates the breakdown of blood clots. It acts as an enzyme to convert plasminogen into its active form plasmin, the major enzyme responsible for clot breakdown. It is a serine protease ( EC 3.4.21.68) found on endothelial cells lining the ...
Tenecteplase. Tenecteplase, sold under the trade names TNKase, Metalyse and Elaxim, is an enzyme used as a thrombolytic drug . Tenecteplase is a tissue plasminogen activator (tPA) produced by recombinant DNA technology using an established mammalian cell line ( Chinese hamster ovary cells ). Tenecteplase is a 527 amino acid glycoprotein ...
A cerebroprotectant (formerly known as a neuroprotectant) is a drug that is intended to protect the brain after the onset of acute ischemic stroke. [1] As stroke is the second largest cause of death worldwide and a leading cause of adult disability, over 150 drugs have been tested in clinical trials to provide cerebroprotection.
Plasminogen activators are serine proteases that catalyze the activation of plasmin via proteolytic cleavage of its zymogen form plasminogen. Plasmin is an important factor in fibrinolysis, the breakdown of fibrin polymers formed during blood clotting. There are two main plasminogen activators: urokinase (uPA) and tissue plasminogen activator ...
Infobox references. 12-O-Tetradecanoylphorbol-13-acetate ( TPA ), also commonly known as tetradecanoylphorbol acetate, tetradecanoyl phorbol acetate, and phorbol 12-myristate 13-acetate ( PMA) is a diester of phorbol. It is a potent tumor promoter often employed in biomedical research to activate the signal transduction enzyme protein kinase C ...
Urokinase is marketed as Kinlytic (formerly Abbokinase) and competes with recombinant tissue plasminogen activator (e.g., alteplase) as a thrombolytic drug. All plasminogen activators (urokinase, tPA) catalyze the production of plasmin, which in turn leads to the breakdown of the fibrin mesh structure in blood clots.
Streptokinase is a thrombolytic medication activating plasminogen by nonenzymatic mechanism. [ 1] As a medication it is used to break down clots in some cases of myocardial infarction (heart attack), pulmonary embolism, and arterial thromboembolism. [ 2] The type of heart attack it is used in is an ST elevation myocardial infarction (STEMI). [ 3]
