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].

IC50 Target[2]

NK1

230 nM (Ki)

NK2

8150 nM (Ki)

体内研究
(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.

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.

生物活性

GR 82334 is a potent and specific reversible tachykinin NK1 receptor antagonist[1]. GR 82334 inhibits substance P-induced sensitization by blocking SP NK1 receptors in naked mole-rats[1].

体内研究
(In Vivo)

GR 82334 (intrathecal administration; 0.1 nmol-1 nmol) excites rats unnary bladder motihty at 1 nmol but not at 0.1 nmol, and the reflex chemonociceptive is reduced by the topical application of capsaicin (4 μg/50 ul)[1].
GR 82334 (10 nM-1 µM; injected between vertebrae L4 and L5) has no effect at 10 nM in neither species, increases heat-induced foot withdrawal latency in mice at doses >100 nM, but no such increase in naked mole-rats, where doses >100 nM evoke a tendency for decreased latency[2].

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

Animal Model: 3-6 month-old, male C57BL/6 mice and 6-18 month-old naked mole-rats[2]
Dosage: 10 nM, 100 nM, and 1 µM
Administration: Lntrathecal injection between vertebrae L4 and L5 
Result: Increased heat-induced foot withdrawal latency in mice.
