Information
Amitriptyline HCl is an inhibitor of bothserotonin transporter (SERT)andnorepinephrine transporter (NET)with Ki of 3.45 nM and 13.3 nM, respectively. Amitriptyline HCl also inhibitshistamine receptor H1,histamine receptor H4,5-HT2andsigma 1 receptorwith K
In vitro
Amitriptyline inhibits Forskolin-stimulated cyclic AMP accumulation with EC50 values of 16.2 μM in intact CHO/DOR cells. Amitriptyline causes a concentration-dependent stimulation of ERK1/2 and GSK-3β phosphorylation with EC50 values of 9.0 μM in CHO/DOR cells. Amitriptyline (15 μM) causes a stimulation of ERK1/2 phosphorylation in C6 cells. Amitriptyline (30 μM) inhibits Forskolin-stimulated adenylyl cyclase activity and antagonizes (−)-U50,488 inhibitory effect in rat nucleus accumbens. Amitriptyline binds the extracellular domain of both 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 EC50 of 50 nM. [6]
In vivo
Amitriptyline (15 mg/kg, i.p.) activates TrkA and TrkB receptors and significantly reduces kainic acid-triggered neuronal cell death in mice. Amitriptyline (15 mg/kg and 30 mg/kg, i.p.) dose-dependently decreases the immobility time in the forced swimming test (FST) of mice. Amitriptyline (15 mg/kg, i.p.) shows a significant 24-h rhythm in the immobility time in the forced swimming test (FST) of mice. Amitriptyline (1 mg/kg and 3 mg/kg) significantly increases the total distance travelled of mice in novel cages. Amitriptyline (10 mg/kg p.o., twice daily) considerably attenuates the hypothermic response to 8-OHDPAT and mCPP in mice. Amitriptyline (10 mg/kg p.o., twice daily) significantly reduces serotonin transporter density by approximately 20% in cortex of mice.
