Cat.No. 3422 - [D-Phe12,Leu14]-Bombesin | Glp-Gln-Arg-Leu-Gly-Asn-Gln-Trp-Ala-Val-Gly-D-Phe-Leu-Leu-NH2 | CAS No. 108437-88-3
Description: Bombesin receptor antagonist

Biological Activity

Bombesin receptor antagonist that inhibits bombesin binding to rat brain with an IC50 value of 2 μM. Inhibits amylase release in vitro (IC50 = 4 μM) and attenuates bombesin-mediated suppression of food intake in vivo.
