Herein, we show that pharmacological inhibition of TRα1 by dronedarone, an amiodarone like compound (shown to antagonize thyroid hormone binding to TRα1), prevented the thyroid hormone induced increase in food intake and heart rate acceleration in rats. This resulted in a marked reduction in body weight. It is likely that thyroid analogs may prove potential therapeutic agents for controlling body weight. © 2006 Blackwell Publishing Ltd. ER -
