Used as a potent serine protease inhibitor in clinical and research settings. Commonly employed in anticoagulation during hemodialysis and continuous renal replacement therapy due to its short half-life and strong inhibitory effect on thrombin and other clotting factors. Applied in the prevention of clotting in extracorporeal circulation circuits. Investigated for use in treating pancreatitis, disseminated intravascular coagulation (DIC), and certain viral infections including coronaviruses, due to its ability to block viral entry into cells. Also utilized in cell culture and bioprocessing to inhibit proteolytic enzymes and protect sensitive proteins.
