[D-Trp34]-Neuropeptide Y TFA 是有效的,选择性神经肽 Y (NPY) Y5 受体激动剂。[D-Trp34]-Neuropeptide Y TFA 在 NPY Y1,Y2,Y4 和 y6 受体上的效力明显较低。[D-Trp34]-Neuropeptide Y TFA 明显增加大鼠的食物摄入量。
生物活性 |
[D-Trp34]-Neuropeptide Y TFA is a potent and selective neuropeptide Y (NPY) Y5 receptor agonist. [D-Trp34]-Neuropeptide Y TFA is a significantly less potent agonist at the NPY Y1, Y2, Y4, and y6 receptors. [D-Trp34]-Neuropeptide Y TFA markedly increases food intake in rats[1][2].

体外研究 (In Vitro) |
[D-Trp34]-Neuropeptide Y TFA 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 TFA 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].

体内研究 (In Vivo) |
[D-Trp34]-Neuropeptide Y TFA (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].

Details |
Negative (lt;0) |
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, add NH4OH (lt;50 μL). 3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. |
Positive (gt;0) |
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO. |
Zero (=0) |
1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration. |
