Description: Peptide to [D-Arg1, D-Phe5, D-Trp7, 9, Leu11]-Substance P Form: Lyophilized powder CAS Number : 96736-12-8Molecular Formula : C79H109N19O12Molecular Weight : 1516.87Purity : > 95%Chemical Structure : D-Arg-Pro-Lys-Pro-D-Phe-Gln-D-Trp-Phe-D-Trp-Leu-Leu-NH2Application : [D-Arg1, D-Phe5, D-Trp7, 9, Leu11]-Substance P initially described as a low potency ghrelin receptor antagonist has surprisingly been found to be a full inverse agonist (EC₅₀ = 5.2 nM). In COS-7 cells transiently transfected with the ghrelin receptor the substance P analog rPKPfQwFwLL decreased the constitutive signaling down to levels observed in untransfected cells. Assuming that constitutive signaling of the ghrelin receptor is of physiological relevance in the regulation of appetite control, inverse agonists of the ghrelin receptor could be interesting for the treatment of obesity.Storage/Stability : Shipped at 4°C.
