Home Neuronal Signaling Serotonin Transporter inhibitor - Histamine Receptor inhibitor - 5-HT Receptor inhibitor Amitriptyline HCl For research use only.

Amitriptyline HCl

Amitriptyline HCl is an inhibitor of both serotonin transporter (SERT) and norepinephrine transporter (NET) with Ki of 3.45 nM and 13.3 nM, respectively. Amitriptyline HCl also inhibits histamine receptor H1, histamine receptor H4, 5-HT2 and sigma 1 receptor with Ki of 0.5 nM, 7.31 nM, 235 nM and 287 nM, respectively. Amitriptyline is a tricyclic antidepressant (TCA).

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. [5] 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. [6] 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. [7] 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. [8]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
