Substance P(1-7) TFA 是神经肽 P 物质 (SP) 的片段。Substance P(1-7) TFA 可对孤束核产生抑制和缓和作用。

生物活性

Substance P(1-7) TFA is a fragment of the neuropeptide, substance P (SP). Substance P(1-7) TFA gives depressor and bradycardic effects when applied to the nucleus tractus solitarius^[1].

体内研究
(In Vivo)

Substance P(1-7) is found to act as a very potent antagonist against the SP-induced responses and is formed locally in the nigra after SP injection. It is proposed that Substance P(1-7) is an endogenous modulator of SP actions^[1]. Injection of low doses of Substance P(1-7) (1.0-4.0 pM simultaneously with SP or SP(5-11) (0.1 nM), reduce aversive behaviours induced by SP or SP(5- 11) significantly. These results indicate that SP(1-7) formed endogenously could modulate the actions of SP or SP(5-11) in the spinal cord^[2].
