Substance P (trifluoroacetate salt)

Substance P is tachykinin neuropeptide that selectively binds to neurokinin 1 (NK1) receptors (Kis = 0.14 and 300 nM for NK1 and NK3, respectively) and has diverse biological activities. It is an endogenous peptide expressed in the central and peripheral nervous systems, including the enteric nervous system and in immune cells. Substance P is released with other neurotransmitters in the dorsal horn of the spinal cord following noxious peripheral stimulation and induces pain through NK1 receptors. The NK1 receptor is internalized following substance P binding, and in a rat hindpaw model of inflammation it is internalized in a greater number of spinal cord neurons following a mechanical or non-noxious stimuli, indicating a role for substance P in inflammation and hyperalgesia. Substance P is also involved in depression, anxiety, seizures, and emesis among other functions.Formal Name: (S)-2-((S)-1-(L-arginyl-L-prolyl-L-lysyl)pyrrolidine-2-carboxamido)-N1-((S)-5-amino-1-(((S)-1-(((S)-1-((2-(((S)-1-(((S)-1-amino-4-(methylthio)-1-oxobutan-2-yl)amino)-4-methyl-1-oxopentan-2-yl)amino)-2-oxoethyl)amino)-1-oxo-3-phenylpropan-2-yl)amino)-1-oxo-3-phenylpropan-2-yl)amino)-1,5-dioxopentan-2-yl)pentanediamide, trifluoroacetate salt.
