Upamostat (WX-671) is a serine protease inhibitor. Upamostat is the orally available prodrug of the WX-UK1, which is a urokinase plasminogen activator (uPA) inhibitor. Upamostat is the urokinase plasminogen activator (uPA) inhibitor. Upamostat is the oral pro-drug of the active metabolite WX-UK1, a novel uPA inhibitor[1]. Upamostat inhibits the urokinase-type plasminogen activator (uPA) system, which plays a major role in tumor invasion and metastasis. Upamostat is the orally available amidoxime- (i.e. hydroxyamidine-) prodrug of the pharmacologically active form, WX-UK1[2]. The validated method is used to evaluate the pharmacokinetics of Upamostat (Mesupron) in rats. The mean plasma concentrations of Upamostat after a single intravenous injection of 2 mg/kg in five rats are measured. The substance decays in a mono-phasic pattern with a terminal half-life of 0.5 h its volume of distribution is 2.0 L/kg, and clearance is about 2.7 L/h/kg[3]. Rats[3] Five 9-week old Sprague-Dawley rats are administered a single intravenous injection of 2 mg/kg of Upamostat. Upamostat is dissolved in a mixture of normal saline, dimethylacetamide, polyethylene glycol 400 and DMSO (3:3:3:1). Blood samples (0.15 mL) are taken serially for up to 10 h after drug administration and collected in heparinized centrifuge tubes. After centrifugation at 13,200 rpm for 10 min, the plasma samples are analyzed[3]. Serine protease, uPA[1] In Vitro Upamostat is the urokinase plasminogen activator (uPA) inhibitor. Upamostat is the oral pro-drug of the active metabolite WX-UK1, a novel uPA inhibitor[1]. Upamostat inhibits the urokinase-type plasminogen activator (uPA) system, which plays a major role in tumor invasion and metastasis. Upamostat is the orally available amidoxime- (i.e. hydroxyamidine-) prodrug of the pharmacologically active form, WX-UK1[2].
