(D-ARG1,D-TRP7·9,LEU11)-SUBSTANCE P 用途与合成方法
Spantide I 是substance P 的类似物,是选择性的神经激肽-1 受体 (NK1 receptor) 的拮抗剂,其对NK1 和 NK2 受体的 Ki 值分别为 230 nM 和 8150 nM。Spantide I 可减少感染角膜的1型细胞因子和增强2型细胞因子 IL-10,从而显著减少角膜穿孔。
NK1 230 nM (Ki) |
NK2 8150 nM (Ki) |
Spantide I (50 and 100 nM perfused through the cerebral ventricles) causes a complete respiratory arrest in all of the examined animals.
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.
Animal Model: | Female, 8-week-old C57BL/6 (B6) and BALB/c mice. |
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. |
