| Background | It is a SERT and NET inhibitor. It also binds to DAT and also inhibits Adrenergic receptor, mAChR, Histamine receptor and 5-HT receptor. In addition, it is a TrkA and TrkA receptor agonist with strong neurotrophic activity. |
| Biological Activity | Amitriptyline HCl 是一种 serotonin transporter (SERT) 和 norepinephrine transporter (NET) 的抑制剂，其Ki值分别为3.45 nM和13.3 nM。Amitriptyline HCl 还可抑制histamine receptor H1、histamine receptor H4、5-HT2 和 sigma 1 receptor，对应的Ki值分别是0.5 nM、7.31 nM、235 nM和287 nM。Amitriptyline 是一种三环抗抑郁药物。[1-8] |
| In Vitro | Amitriptyline抑制毛喉素刺激的环AMP聚集，在完整CHO/DOR细胞中EC50值为16.2 μM。Amitriptyline浓度依赖性刺激ERK1/2和GSK-3β磷酸化作用，CHO/DOR细胞中EC50值为9.0 μM。Amitriptyline(15 μM)刺激C6细胞中ERK1/2磷酸化。Amitriptyline(30 μM)抑制毛喉素刺激的腺苷酸环化酶活性，并拮抗大鼠伏核中( )-U50，488的抑制作用。[5] Amitriptyline结合到TrkA和TrkB的胞外结构域，并促进TrkA-TrkB受体异源二聚化。Amitriptyline(< 500 nM)促进初级神经元中TrkA自身磷酸化，并诱导PC12细胞中神经突增生。Amitriptyline选择性保护T17细胞免于细胞凋亡，EC50为50 nM。[6] |
| In Vivo | 在小鼠中，Amitriptyline(15 mg/kg，i.p.)激活TrkA和TrkB受体，并显著减少红藻氨酸引起的神经元细胞死亡。[6] Amitriptyline(15 mg/kg 和30 mg/kg，i.p.)剂量依赖性减少小鼠强迫性游泳测试(FST)中的不动时间。小鼠强迫性游泳测试(FST)中，Amitriptyline(15 mg/kg，i.p.)使小鼠不动时间现出显著的24-h节律性。[7] Amitriptyline(1 mg/kg和3 mg/kg)显著增加小鼠在新笼子实验中总的行走距离。Amitriptyline(10 mg/kg p.o.，每天两次)大大减弱小鼠体内对8-OHDPAT和mCPP的低体温响应。Amitriptyline(10 mg/kg p.o.，每天两次)显著降低小鼠大脑皮层中大约20%的血清素转运体密度。[8] |
