Additional Information:

Camostat mesilate is a serine protease inhibitor inhibiting plasmin, kallikrein, thrombin as well as trypsin, which attenuates pancreatic fibrosis (1) and it reduces weight gain and improves metabolism in obese rodent models (2). This compound is in clinical use in Japan for pancreatitis (3). It inhibits influenza virus replication in human tracheal epithelial cells (4) and also reduces infection of Calu-3 lung cells by SARS-CoV-2 (responsible for COVID-19) via inhibition of the serine protease TMPRSS2 required for viral spike protein priming (5).
