Abstract
Purpose. Our previously data on orexigenic peptides (orexin, ghrelin) showed antagonists of peptides receptors as correctors of the emotional-motivational and cognitive spheres. Currently, a close relationship between ghrelin and orexin with neuropetide Y has been shown in feeding and emotional behavior.
The aim of this work was to analyze the effect of the NPY antagonist Y1R BMS 193885 on emotional and intraspecies behavior, as well as on the reinforcing properties of ethanol in rats.
Methods. We used the “open field” test, “elevated plus-maze”, Porsolt’s forced swimming test, “resident – intruder” test, conditional place preference (CPP). BMS 193885 1 mg/ml, 20 μl intranasally did not cause an anxiogenic effect in the “elevated plus-maze”.
Results. In the Porsolt’s test, there was also no increase in the level of depression. Moreover, there was a significant decrease in the number and time of dives, as an indirect indicator of a decrease in the level of depression. At the same time, in the “resident – intruder” test were decreased protective behavior, as an indicator of a decrease in the stress of intraspecific interaction in the absence of aggression. Moreover, local movements were increased in the “open field” test as an indicator of the animal’s activity impaired by fear. BMS 193885 had no effect on the expression of the CPP of ethanol.
Conclusion. Thus, it was previously shown that the BMS 193885 is a powerful, selective, brain-penetrating Y1 receptor antagonist, it reduces food intake and body weight in animal models of obesity both after acute and chronic administration. Our data indicate that the decrease in food intake is not associated with the level of anxiety, depression, or with a change in intraspecific interaction. It has been previously shown that NPY reduces alcohol consumption. Our data indicate that the Y1R antagonist of the neuropeptide Y BMS 193885 does not cause a change in the CPP of alcohol.
