摘要：

Administration of the CB1 receptor antagonist SR 141716 [N-piperidino-5-(4-chlorophenyl)- 1-(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide]. suppresses intake of highly palatable (high carbohydrate) food. However, the effects of SR 141716 on intake of foods with varying macronutrient compositions, and in non-deprived animals have not been well studied. In the present study, non-deprived rats were injected intraperitoneally with SR 141716 (0.03-3.0 mg/kg) and presented with a high carbohydrate, high fat, or normal chow diet. Food intake and locomotor activity were recorded for 120 min. Results showed that SR 141716 significantly suppressed food intake irrespective of the composition of the test food without affecting locomotor activity. These data suggest that food deprivation or high palatability of the ingesta are not necessary to observe the suppressive effects of SR 141716 on food intake. (C) 2003 Elsevier Ireland Ltd.
