Tetraethylammonium dibromidotricarbonyl(o-toluidine)rhenate(I)

Interaction of Tetraethylammonium

A number of compounds related to TEA+ (tetraethylammonium ion) were injected into squid axons and their effects on gK (the potassium conductance) were determined. In most of these ions a quaternary nitrogen is surrounded by three ethyl groups and a fourth group that is very hydrophobic. Several of the ions cause inactivation of gK, a type of ionic gating that is not normally seen in squid axon;...

Ganglionic blockade with tetraethylammonium in conscious rats.

The sympathetic ganglionic blocking agent tetraethylammonium has been used as a clearance marker for the measurement of renal plasma flow, but the sympathetic ganglionic blocking dose in rats is unknown. In light of differential reflex activation of sympathetic nerve activity to heart and kidney, we compared the effect of tetraethylammonium on renal nerve activity, mean arterial pressure, and h...

Tetraethylammonium-induced synaptic plasticity in rat neocortex.

Recordings were obtained from neurons in layer II/III of slices of rat frontal cortex maintained in vitro. We investigated whether brief application of the potassium channel blocker tetraethylammonium (TEA), which induces a novel form of synaptic plasticity in the CA1 region of the hippocampus referred to as LTPK, evokes similar responses in neocortex. Consistent with previous findings, TEA pro...

Arrangement of Kv1 α subunits dictates sensitivity to tetraethylammonium

Shaker-related Kv1 channels contain four channel-forming alpha subunits. Subfamily member Kv1.1 often occurs oligomerized with Kv1.2 alpha subunits in synaptic membranes, and so information was sought on the influence of their positions within tetramers on the channels' properties. Kv1.1 and 1.2 alpha genes were tandem linked in various arrangements, followed by expression as single-chain prote...
