Introduction：Basic information about CAS 56104-22-4|(Pyr5)-Substance P (5-11), including its chemical name, molecular formula, synonyms, physicochemical properties, and safety information, etc.
[Glp5] Substance P (5-11) is an octapeptide. [Glp5] Substance P (5-11) is one of the main substance P fragments in rat central nervous system (CNS). [Glp5] Substance P (5-11) locally modulates dopamine release in rat striatum[1].

In Vitro
[Glp5] Substance P (5-11) (0.12 nM-10 μM; rat striatum) modifies spontaneous dopamine outflow with a significant increase in dopamine outflow at 0.1 nM and a smaller effect at 1 nM, whereas concentrations lower than 0.1 nM or higher than 1 nM failed to modify dopamine release. [Glp5] Substance P (5-11) and K+ has additive effect, promoting the release of dopamine[1].
