Discontinued Product
[D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P (Cat. No. 1946) has been withdrawn from sale for commercial reasons.
Description: Potent ghrelin receptor inverse agonist; Antagonist at other neuropeptide receptors
Biological Activity
[D-Arg1,D-Phe5,D-Trp7,9,Leu11]-Substance P is a broad spectrum neuropeptide inverse agonist and antagonist. 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.
