Camostat Mesylate, also known as Foipan or FOY 305, is a synthetic serine protease inhibitor that is often used to treat pancreatitis pain (1). Camostat Mesylate attenuates airway epithelial sodium channel (ENaC) function by inhibiting channel-activating proteases (CAPs) with an IC50 of 50 nM (2). Camostat Mesylate inhibition of trypsin decreased food intake, body weight, blood glucose, liver weight, and lipidosis and increased FGF21 expression in obese mice (3).
Camostat Mesylate is an effective inhibitor of TMPRSS2, a serine protease used by SARS-CoV-2/COVID-19 for viral S-protein priming and cell entry. Pre-treatment of human lung cancer cells with 100 μM Camostat Mesylate significantly reduced COVID-19 viral entry (4).
