| Tetraethylammonium Chloride Usage And Synthesis |
| Chemical Properties | white crystalline powder |
| Uses | Medicine (nerve-blocking agent). |
| Uses | Tetraethylammonium Chloride can be used as a source of tetraethylammonium ions for various pharmaceutical studies and has the ability to block K+ channels in various tissues. Tetraethylammonium Chloride can also block the transmission of nervous impulses across autonomic ganglions. |
| Uses | Tetraethylammonium chloride (TEAC) has been used:
used for inhibition of peroxynitrite induced relaxation in rat aorta rings as a pharmacological blocker of K+ current and Ca2+ induced K+ current in antennal lobe neurons for the induction of TEAC sensitive currents in cochlear inner hair cells digested with proteolytic enzymes and analyze its properties |
| Definition | ChEBI: A quarternary ammonium chloride salt in which the cation has four ethyl substituents around the central nitrogen. |

| Biological Activity | Non-selective K + channel blocker. |
| Biochem/physiol Actions | Tetraethylammonium chloride (TEAC) blocks K+ channels non-specifically. In rat aorta rings, tetraethylammonium inhibits relaxation induced by peroxynitrite. It blocks nicotinic acetylcholine neurotransmission by blocking the receptor-mediated K+ currents. TEAC can increase the contractility and mobility of colon and rectum and is a therapeutic option for Hirschsprung′s disease patients. TEAC reduces the inflammatory responses, improves cardiac, vascular and hemodynamic properties during early sepsis in animals. TEAC has cytotoxic and anti-proliferative potential and induces apoptosis in glioma cells by downregulating B-cell lymphoma-2 (Bcl-2) and upregulating Bcl-2 associated X (Bax). |
| in vitro | tetraethylammonium (tea) is a small ion that is thought to block open k channels by binding either to an internal or to an external site. for this reason, it has been used to probe the ion conduction pathway or pore of k channel mutants and a k channel chimera. tea blocks k+ channels at two sites, which define the inner and outer mouths of the channel pores [1]. |
| in vivo | vasorelaxant effect of taurine can be diminished by tea in rat isolated arteries [2] |
| storage | Room temperature (desiccate) |
| Purification Methods | Crystallise the chloride from EtOH by adding diethyl ether, from warm water by adding EtOH and diethyl ether, from dimethylacetamide or from CH2Cl2 by addition of diethyl ether. Dry it over P2O5 in vacuum for several days. It also crystallises from acetone/CH2Cl2/hexane (2:2:1) [Blau & Espenson J Am Chem Soc 108 1962 1986, White & Murray J Am Chem Soc 109 2576 1987].
