Tetraethylammonium chloride is a non-selective potassium channel blocker. Tetraethylammonium chloride is a good substrate for organic cation transporter (OCTN1). Tetraethylammonium chloride antitumor properties^[1][2].

Tetraethylammonium (0.2-60 mM; 24-72 hours; C6 and 9L glioma cells) treatment inhibits the proliferation of C6 and 9L cells in a dose- and time-dependent manner^[1].
Tetraethylammonium (40 mM; 24-72 hours; C6 and 9L glioma cells) treatment significantly increases apoptosis in cells^[1].
Tetraethylammonium (40 mM; 12-48 hours; C6 and 9L glioma cells) treatment significantly elevates Bax/Bcl-2 protein ratio in a time-dependent manner^[1].
The generation of intracellular ROS increased in C6 and 9L cells by the addition of 20 and 40 mM Tetraethylammonium^[1].

Tetraethylammonium (1 mM, 3 mM, and 5 mM) significantly increases the amplitude and frequency of contractility of colon and rectum from rats in longitudinal and circular direction. Tetraethylammonium at 5 mM and 15 mM concentrations shows no effect on histology of colon and rectum from rats that are administered locally with Tetraethylammonium into colon lumen from anus for 10 days^[2].
