生物活性

[D-Pro2,D-Phe7,D-Trp9] Substance P is aSubstance P(HY-P0201) analogue. [D-Pro2,D-Phe7,D-Trp9]Substance Pis an inhibitor of Substance P. [D-Pro2,D-Phe7,D-Trp9] Substance P contracts guinea-pig ileum (GPI) indirectly[1][2].

IC50& Target

Substance P[2]

体外研究
(In Vitro)

[D-Pro2,D-Phe7,D-Trp9] Substance P (10-100 μM; 2 min or 10 min) produces dose-related contractions of the guinea-pig ileum and in the rabbit external jugular vein[1].

体内研究
(In Vivo)

[D-Pro2,D-Phe7,D-Trp9] Substance P (1-2 mg/kg; i.v.; once) inhibits the salivary secretion which was induced by Substance P in rats. In the dosage range at 1-1.5 mg/kg slightly increases the blood pressure[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:

 ContentsAssign value
Acidic amino acidAsp (D), Glu (E), and the C-terminal -COOH.-1
Basic amino acidArg (R), Lys (K), His (H), and the N-terminal -NH2+1
Neutral amino acidGly (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 peptideDetails
Negative (<0)1.  Try to dissolve the peptide in water first.
2.  If water fails, add NH4OH (<50 μL).
3.  If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>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.
