    • SD rats, fasted overnight, were anesthetized with inactin (100 mg/kg ip), surgically prepared with tracheal (PE205) and femoral arterial and venous cannula (PE50) and placed on a water-jacketed heating pad. The arterial pressure and heart rate signals were fed into a PONEMAH Physiology Platform (Gould Instrument Systems, Valley View OH) and data were recorded every 5 seconds during the experiment. NPY (5 μg in 0.25 mL of saline), was administered to the rats at 15 min intervals as an iv bolus. Following the third bolus injection of NPY, the test compound (3 mg/kg in a saline vehicle, 1 mL/kg) was dosed iv and three subsequent NPY injections were administered

    • SD rats with icv cannula were fed powdered rat chow ad libitum. Between 10-11 am during the light cycle, 2f (120 μg) or vehicle (1 μL of propylene glycol) were co-infused with NPY (5 μg in 4 μL sterile water) via the icv cannula (total volume 5 μL over 1 min). After dosing, food intake over the next 4 h was measured. Rats received two treatments in a cross-over experiment separated by 2 days

    • SD rats were individually housed in suspended wire cages with powdered chow and water provided ad libitum. Before the experiment, rats were fasted overnight. On the day of the experiment, rats were dosed with 2f (40 mg/kg, po) or vehicle (0.5% methyl cellulose in water, dosing volume 1.5 mL). Food, in pre-weighed jars, was restored to the cages 2 or 4 h post dose. Food intake was recorded 2 and 4 h after restoring food
