Used as a serine protease inhibitor, particularly effective in inhibiting trypsin-like enzymes. Commonly applied in research to block viral entry, including coronaviruses, by inhibiting host cell proteases such as TMPRSS2. Employed in studies related to pancreatitis due to its ability to reduce pancreatic enzyme activity. Also investigated for potential therapeutic use in cancer and inflammatory conditions owing to its modulation of proteolytic pathways involved in disease progression.
