生物活性
Patamostat (E-3123) 是一種有效的蛋白酶 (protease) 抑制劑。Patamostat 有效抑制胰蛋白酶，纖溶酶和凝血酶，IC50 分別為 39 nM，950 nM 和 1.9 μM。Patamostat 有潛力用于急性胰腺炎的研究。靶點
IC50: 39 nM (trypsin), 950 nM (plasmin) and 1.9 μM (thrombin)
體內研究
Intravenous infusion of Patamostat (E-3123) at 0.03-0.3 mg/kg in rats or at 0.3-3.0 mg/kg in rabbits reduced mortality after the induction of pancreatitis in a dose-dependent manner. In dogs with pancreatitis, increases in serum trypsin and lipase activities were significantly reduced by infusion of Patamostat at 1.0 and 3.0 mg/kg.
Patamostat (E3123; continuous infusion in a dose of 2 mg/kg per h) 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.
| Animal Model: | Male Wistar rats weighing about 350 g |
| Dosage: | 2 mg/kg |
| Administration: | Continuous infusion per h for 1 h |
| Result: | Significantly improved the survival rate. |
