Used in research for its inhibitory effects on serine proteases, particularly in studies related to inflammation, viral entry, and pancreatic disorders. Shows potential in blocking the activation of certain viruses by inhibiting host cell proteases required for viral fusion. Also investigated for its role in reducing tissue damage in acute pancreatitis due to its anti-inflammatory and protease-modulating properties. Employed as a reference compound in metabolic and pharmacokinetic studies of camostat derivatives.
