In vitro study | Amitriptyline inhibited Forskolin-stimulated ring AMP aggregation with an EC50 value of 16.2 μm in intact CHO/DOR cells. Amitriptyline concentration-dependently stimulated ERK1/2 and GSK-3β phosphorylation with an EC50 value of 9.0 μm in CHO/DOR cells. Amitriptyline (15 μm) stimulates ERK1/2 phosphorylation in C6 cells. Amitriptyline (30 μm) inhibits Forskolin-stimulated adenylate cyclase activity and antagonizes the inhibitory effect of (−)-U 50,488 in the nucleus accumbens of rats. Amitriptyline binds to the extracellular domains of TrkA and TrkB and promotes TrkA-TrkB receptor heterodimerization. Amitriptyline (< 500 nM) promotes TrkA autophosphorylation in primary neurons and induces neurite outgrowth in PC12 cells. Amitriptyline selectively protects T17 cells from apoptosis with an EC50 of 50 nM. |
In vivo study | In mice, Amitriptyline (15 mg/kg, I. p.) activates TrkA and TrkB receptors and significantly reduces kainic acid-induced neuronal cell death. Amitriptyline (15 mg/kg and 30 mg/kg, I. p.) dose-dependently reduced immobility time in the forced swimming test (FST) in mice. In the mouse compulsive swimming test (FST), Amitriptyline (15 mg/kg, I. p.) showed a significant 24-h rhythm of immobility time in mice. Amitriptyline (1 mg/kg and 3 mg/kg) significantly increased the total walking distance of mice in the new cage experiment. Amitriptyline (10 mg/kg p.o., twice daily) greatly attenuated the hypothermic response to 8-OHDPAT and mCPP in mice. Amitriptyline (10 mg/kg p.o., twice daily) significantly reduced the serotonin transporter density in the cerebral cortex of mice by approximately 20%. |
