Background

Bombesin is a neuropeptide with diverse biological activities originally isolated from the skin of B. bombina and B. variegata variegata amphibians.^1,2 It binds to the gastrin-releasing peptide receptor (GRPR) in rat pancreatic acinar cells (K_i = 1.88 nM) and to frog bombesin receptor subtype 4 (BB₄) in CHO cells overexpressing the receptor (K_i = 1.7 nM).³ Hypothalamic paraventricular microinfusion of bombesin (100 ng per animal) increases blood glucose, free fatty acids, and corticosterone levels in rats.⁴ Bombesin (50 ng per animal) injection into the preoptic area decreases food intake by food-deprived or insulin pretreated rats.⁵ It delays gastric emptying in rats by 55.8% when administered at a dose of 16 μg/kg (i.p.) and inhibits gastric secretion at a dose of 500 ng per animal.^6,7
