生物活性

Neuropeptide W-23 (human) (NPW-23), the active form of Neuropeptide W, is an endogenous agonist of NPBW1 (GPR7) and NPBW2 (GPR8).

性状

Solid

IC50 & Target[1][2]

NPBW1, NPBW2

体外研究(In Vitro)

Neuropeptide W-23 (human) (NPW-23) increases the I_Ca,L in transfected human embryonic kidney 293 cells and VSMCs via GPR7.
Neuropeptide W-23 (human) increases the expression of pan phospho-PKC, intracellular diacylglycerol level, and the second messenger catalyzed by PLC.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

Neuropeptide W-23 (human) (NPW-23) (0.3-3.0 nM; intracerebroventricular injection; 2 μL) increases total behavioral activity, including locomotion and grooming in conscious rats.
Neuropeptide W-23 (human) (NPW-23) (2-8 nM; i.c.v.; 10 μL) shows anorexigenic effect in rats.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male Harlan Sprague-Dawley rats, 250–300 g
Dosage:	0.3, 1.0 and 3.0 nM
Administration:	Intracerebroventricular injection, 2 μL
Result:	Caused significant increases in mean arterial pressure. Demonstrated a significant increase in total activity, ambulatory activity, and duration of stereotypy.

Animal Model:	Male Wistar rats weighing 250–300 g
Dosage:	2, 4, 6 and 8 nM
Administration:	Intra-cerebroventricular injection, 10 μL
Result:	Decreased dark feeding and fasting-induced feeding, decreased feeding intake and weight gain.

运输条件

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 (<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.
