Bombesin (also known as Bombesin 14, Alytesin, 2-L-glutamine-6-L-asparagine-, Dihydrochloride, Bombesin, Bombesin trifluoroacetate salt) is a metabolic research peptide. Bombesin is a tetradecapeptide that acts as a bombesin receptor agonist, influencing various physiological processes.

Bombesin is a naturally occurring tetradecapeptide that functions as an agonist for bombesin receptors. It is known to affect gastrointestinal function, thermoregulation, and endocrine activity. Research into bombesin has explored its potential in gastroprotection and its role in modulating thyroxine 5'-deiodinase activity in brown adipose tissue. The compound is currently investigational, with studies also focusing on its application in targeted therapy, particularly for small cell lung cancer, through bombesin-drug conjugates. The literature frequently reviews the pharmacology and physiology of bombesin-like peptides and their receptors.
