  3. Spantide I TFA

Spantide I TFA, a substance P analog, is a selective NK1 receptor antagonist, with Ki values of 230 nM and 8150 nM for NK1 and NK2 receptor, respectively. Spantide I provides an approach to reduce type 1 and enhance the type 2 cytokine IL-10 in the infected cornea, leading to a significant reduction in corneal perforation.

製品説明

Spantide I TFA, a substance P analog, is a selective NK1 receptor antagonist, with Ki values of 230 nM and 8150 nM for NK1 and NK2 receptor, respectively. Spantide I provides an approach to reduce type 1 and enhance the type 2 cytokine IL-10 in the infected cornea, leading to a significant reduction in corneal perforation[1][2][3].

体内実験

Spantide I (50 and 100 nM perfused through the cerebral ventricles) causes a complete respiratory arrest in all of the examined animals[2].
Spantide I (36 μg/mouse, ip daily) significantly decreases the number of perforated corneas, bacterial counts, and PMNs. Spantide I also downregulates the mRNA levels for type I cytokines (e.g., IFN-γ) as well as MIP-2, IL-6, TNF-α, and IL-1β[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female, 8-week-old C57BL/6 (B6) and BALB/c mice[3].
Dosage: 36 μg/mouse.
Administration: IP on days -1 and 0 (day of infection) and daily through 5 days pi (post infection).
Result: At 3 and 5 days pi, compound-treated mice had significantly less severe ocular disease than did the PBS-treated mice.
Contained significantly fewer PMNs than the corneas of PBS-treated mice at 3 and 5 days pi.
Significantly reduced levels of corneal TNF-α mRNA at 3 and 5 days pi.
Significantly reduced the level of IL-18 mRNA at 1 day pi.

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:

  内容 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
