PAQ is a neuroprotective agent. It protects dopaminergic neurons from cell death without inhibiting glial cell proliferation in a rat midbrain culture model of Parkinson's disease when used at a concentration of 10 μM. PAQ (25 or 50 mg/kg, twice per day) prevents loss of dopaminergic neurons in the substantia nigra in a mouse model of Parkinson's disease induced by MPTP.
[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。
