Patamostat (E-3123) is a potent protease inhibitor. Patamostat potently inhibits trypsin, plasmin and thrombin with IC50s of 39 nM, 950 nM and 1.9 μM, respectively. Patamostat may possess suppressing effects on pathogenesis and development of acute pancreatitis[1][2].
Patamostat (intravenous infusion) at 0.03-0.3 mg/kg in rats or at 0.3-3.0 mg/kg in rabbits reduces mortality after the induction of pancreatitis in a dose-dependent manner[1].
Patamostat (1.0-3.0 mg/kg; intravenous infusion) reduces the increases of serum trypsin and lipase activities in dogs with pancreatitis[1].
Patamostat (2 mg/kg per h; continuous infusion) improves almost all parameters, including mortality rate, serum and ascitic fluid amylase levels, plasma endotoxin and serum FDP levels, and distribution of lysosomal enzyme in male Wistar rats[2].
