| In Vivo | Emricasan (IDN-6556) is orally active that is retained in the liver for prolonged period of time. TUNEL-positive cells are considerably increased by five-fold in mice fed a HFD and are reduced under Emricasan treatment. In accordance with this observation caspase-3 and -8 are increased in HFD-fed mice by 1.5- and 1.3-fold respectively and are significantly decreased by Emricasan treatment[1].When comparing efficacy by multiple routes of administration, Emricasan is administered i.p., p.o., i.m., or i.v. (0.03-3 mg/kg). Caspase 3-like activities, measured as DEVD-AMC cleavage, dose dependently decreased with a 92.5% reduction after the highest dose of Emricasan (3 mg/kg). Emricasan is initially tested in the α-Fas model of liver injury, marked hepatocellular apoptosis, and peak ALT activities within 6 h. Emricasan is administered i.p. immediately after administration of α-Fas, ALT activities, measured 6 h later, decreased in a dose-dependent manner with an ED50 value of 0.08 (0.06-0.12) mg/kg[2]. Emricasan is a highly selective pan-caspase inhibitor demonstrating irreversible inhibition and a significant first-pass effect. In both syngeneic mouse islets and human islets transplanted into immunodeficient mice, Emricasan (i.p., 20 mg/kg) given for 7 days post-transplant led to a significantly enhanced rate of diabetes reversal as compared to vehicle[3]. |
| Animal Admin | Mice[1] The male C57BL/6J mice are age-matched and used at approximately 12-16 weeks of age. Four groups are studied (n=60) with 15 mice per group. Groups 1 and 3 receive regular chow. Groups 2 and 4 receive HFD and 50 g/L (Sucrose) is added to drinking water for 20 weeks. Groups 3 and 4 receive Emricasan 0.3 mg/kg/day per os, and Group 1 and 2 receive the vehicle. The oral administration of Emricasan at doses of 0.3 mg/kg corresponds to the ED90 value to prevent liver injury in the model of α-Fas-induced liver injury. Total body weight is measured at 0, 5, 10, 15 and 20 weeks. Rats[2] The male Sprague-Dawley rats are cannulated in the carotid artery under isoflurane anesthesia and allowed to recover for at least 1 day before drug administration. Blood (100 μL/sample) is taken from the carotid cannula 2 to 240 min after administration of Emricasan (i.v., s.c., p.o., or i.p.). Serum is prepared and frozen immediately until analysis. In studies measuring drug concentrations in portal and systemic blood, individual rats are bled (three animals per time point) simultaneously from the portal vein and inferior vena cava. In the biliary excretion study, bile is collected from the common bile duct after i.v. and p.o. administration of Emricasan (10 mg/kg) over a 24-h period on ice and frozen until analysis. |
