Bombina Bombesin

Anastasi A, Erspamer V, Bucci M (1971) Isolation and structure of bombesin and alytesin, 2 analogous active peptides from skin of European amphibians Bombina and Alytes. Experientia 27 166-167... 

Bombesin is a tetradecapeptide isolated from the skin of the amphibian frog Bombina bombina (Anastasi et al, 1971). It has been proposed that bombesin-related peptides may be released from the gastrointestinal tract in response to ingested food, and that they bridge the gut and brain via neurocrine means to inhibit further food intake (Merah et al, 1999). 

BOMBESIN RECEPTOR AGONISTS act at sites that are sensitive to bombesin, a tetradecapeptide derived from the skin of Bombina bombina and certain other frogs. This peptide has been relatively extensively studied, so has given its name to a family of peptides and receptors. Contrary to the original belief, the bombesin (BB) sequence is not found in mammals but a number of similar peptide sequences have...
