Broad spectrum neuropeptide antagonist/inverse agonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. Induces apoptosis and inhibits cancer cell growth in vitro.
(Modifications: Arg-1 = D-Arg, Phe-5 = D-Phe, Trp-7 = Trp-9 = D-Trp, Leu-11 = C-terminal amide)
