Eprotirome (KB2115)

Animal experiment:

Twelve-week old male ob/ob mice are used in this study. A catheter is implanted into the right internal jugular vein before the hyperinsulinemic-euglycemic clamp. After recovery, mice are administered Eprotirome (0.3 mg/kg) via intraperitoneal injection for 10 days. On the day of the clamp experiment, conscious, overnight-fasted mice receive a primed (10 μCi) and constant rate intravenous infusion (0.1 μCi /min) of [3-3H] glucose to measure basal glucose turnover. After 60 to 75 minutes of labeled glucose infusion, the hyperinsulinemic-euglycemic clamp is performed with continuous infusion of insulin (12 mU/kg/min) and variable infusion of 25% glucose to maintain euglycemia (~120 mg/dL). Blood samples are collected by tail bleeding (approximately every 10 min) to measure blood glucose concentrations[1].
