Broad spectrum neuropeptide inverse agonist and antagonist. Potent full inverse agonist for the ghrelin receptor (EC50 = 5.2 nM); diminishes constitutive ghrelin receptor signaling. Also antagonist at tachykinin, bradykinin, CCK and bombesin receptors. In
[Sar9,Met(O2)11]-Substance P TFA is a selective tachykinin NK1 receptor agonist.[Sar9,Met(O2)11]-Substance P and septide (10-100 pmol per rat, i.c.v.) are equipotent in increasing mean arterial blood pressure (MAP) and heart rate (HR), yet they have dissi
Substance P TFA (Neurokinin P TFA) is a neuropeptide that functions as both a neurotransmitter and neuromodulator in the central nervous system, specifically targeting the neurokinin 1 receptor (NK1-receptor, NK1R).
[Sar9]-Substance P is one of NK-1 receptor agonist. The action of SP on progesterone metabolism was mimicked by the rNK1-specific agonist [Sar-9,Met(O2)11]-SP.
Substance P (1-9) is a nonapeptide that reduces the inactivation of substance P in the guinea-pig ileum and urinary bladder, and is responsible for various excitatory effects on central and peripheral neurons.
[Glp5,(Me)Phe8,Sar9] Substance P (5-11) (DiMe-C7) 是一种 Substance P 类似物,在大鼠大脑中对神经激肽 1 受体 (NK1R) 的作用与 Substance P 大致相等,但作用时间大大延长。[Glp5,(Me)Phe8,Sar9] Substance P (5-11) 能选择性地激活大鼠大脑间脑和中脑皮层的多巴胺代谢。[Glp5,(Me)Phe8,Sar9] Substance P (5-11) 还可增加大鼠运动活性,诱导成瘾剂寻求行为的恢复。
