Tetraethylammonium Chloride - CAS 56-34-8

K+ channels blocker; cholinoreceptors antagonist; ganglioblocker.

8H20ClN–>, synthetic.

The exposure of rat tracheal segments to threshold/subthreshold concentrations of TEA produces remarkable Airway Hyperresponsiveness (AH) to cooling provocation [Chand N.].

K+ channel blockade is involved in the induction of non specific AH in this model [4]. At the concentration of 10 mM: EC50 = 3.4 �M (1.8 – 6.4).

1 mM blocks InsP3-induced Ca2+ release in microsomal fractions isolated from rat brain incubated in media containing 100 mM KCl. Decreases the InsP3-induced Ca2+ release by 80 � 5% [5].
