[ Name ]:
[D-Trp34]-Neuropeptide Y

Biological Activity

[Description]:

[D-Trp34]-Neuropeptide Y is a potent and selective neuropeptide Y (NPY) Y5 receptor agonist. [D-Trp34]-Neuropeptide Y is a significantly less potent agonist at the NPY Y1, Y2, Y4, and y6 receptors. [D-Trp34]-Neuropeptide Y markedly increases food intake in rats[1][2].

NPY Y5 receptor


[In Vitro]

[D-Trp34]-Neuropeptide Y has pKi values of 6.49, 5.43, 7.08, 7.53, 6.55, 5.95, 6.85, 7.41 for hY1, hY2, hY4, hY5, rY1, rY2, rY4, rY5 in CHO cells. [D-Trp34]-Neuropeptide Y has pEC50 values of 6.44, <6, 6.28，7.82 for rY1, rY2 in CHO cells and rY4, rY5 in HEK-293 cells[1].

[In Vivo]

[D-Trp34]-Neuropeptide Y (0, 8 and 16 μg/rat; I.C.V) stimulats food intake to the same extent in both lean and obese rats 1 h after injection at a dose of 16 μg in male Zucker rats[2].
