  1. GPCR/G Protein Neuronal Signaling
  2. Neurokinin Receptor
  3. Spantide I

Spantide I 是substance P 的類似物,是選擇性的神經(jīng)激肽-1 受體 (NK1 receptor) 的拮抗劑,其對NK1 和 NK2 受體的 Ki 值分別為 230 nM 和 8150 nM。Spantide I 可減少感染角膜的1型細(xì)胞因子和增強(qiáng)2型細(xì)胞因子 IL-10,從而顯著減少角膜穿孔。

生物活性

Spantide I, 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].

230 nM (Ki)

NK2

8150 nM (Ki)

體內(nèi)研究
(In Vivo)

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].

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.

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.
