Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. They are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (Voltage-gated, voltage-sensitive, or voltage-dependent sodium channel also called VGSCs or Nav channel) or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels). In excitable cells such as neurons, myocytes, and certain types of glia, sodium channels are responsible for the rising phase of action potentials. Voltage-gated Na+ channels can exist in any of three distinct states: deactivated (closed), activated (open), or inactivated (closed). Ligand-gated sodium channels are activated by binding of a ligand instead of a change in membrane potential.

    Amitriptyline-d6 hydrochloride
    		Inhibitor 99.93%
    Amitriptyline-d6 hydrochloride is the deuterium labeled Amitriptyline hydrochloride (HY-B0527A). Amitriptyline hydrochloride is an orally active tricyclic antidepressant (TCA). Amitriptyline hydrochloride mainly exerts its antidepressant effect by blocking SERT (Ki = 3.45 nM) and NET (Ki = 13.3 nM), thereby increasing the concentrations of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in the synaptic cleft. Amitriptyline hydrochloride is also an agonist at α2A and TrkA/TrkB receptors, thereby exerting analgesic and neurotrophic activities (inhibiting cell apoptosis). Amitriptyline hydrochloride can reduce inflammation, angiogenesis and fibrosis. Amitriptyline hydrochloride binds to DAT (with Ki = 2.58 μM). Amitriptyline hydrochloride has high affinity for a series of receptors and can antagonize muscarinic cholinergic receptors (M1/M2/M3/M4/M5 receptors) (Ki = 11-24 nM), H1 receptors (Ki = 0.5-1.1 nM), adrenergic α1 receptors (Ki = 4.4 nM), etc., resulting in a series of side effects. Amitriptyline hydrochloride can block sodium channels and hERG potassium channel (IC50 = 4.78 μM) and it has cardiotoxicity.
