生物活性

[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].

体外研究
(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].

Peptide Solubility and Storage Guidelines:

1.;;Calculate the length of the peptide.

2.;;Calculate the overall charge of the entire peptide according to the following table:

; Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.;;Recommended solution:

Overall charge of peptide 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.
