背景说明：[Pro9]-Substance P 是一种有效的、可逆的、选择性的 NK-1 速激肽受体激动剂，其 EC50 为 0.93 nM。 [Pro9]-Substance P is a potent, reversible and selective agonist of NK-1 tachykinin receptors with an EC50 of 0.93 nM.
In Vitro：[Pro9]-Substance P can be used as a radio ligand for NK- 1 binding sites.
[Pro9]-Substance P stimulates inositol phosphate formation with an efficacy only slightly lower than that of SP (EC50 values of 0.93 ± 0.07 and 0.45 ± 0.06 nM, respectively) on primary cultures of newborn mouse cortical glial cells.
