Litorin suppresses food intake in rats

Litorin (LIT), a bombesin-like nonapeptide, decreased food intake in rats in a dose-related manner after parenteral injection. LIT decreased deprivation-induced water intake only at a dose much higher than required to suppress feeding. LIT administration did not significantly alter the frequency of observed feeding-associated behaviors, nor did it result in subsequent aversion to an associated novel solution. Litorin shares with bombesin structural features and pharmacological actions that include the suppression of food intake in a manner that mimics natural satiation.
