Chemical Name: N'-[3,5-Bis(trifluoromethyl)phenyl]-N-[4-bromo-2-(2H-tetrazol-5-yl-phenyl]thiourea

Biological Activity

Activator of large-conductance Ca2+-activated potassium channels (BKCa, KCa1.1). Exhibits no modulatory effect on a variety of K+ (KV), Na+ and Ca2+ currents at concentrations <10 μM. Alters gating kinetics, but does not affect single channel conductance. Shown to bind BKCa in open and closed conformations; thought to bind the α subunit.

Technical Data

Soluble to 100 mM in ethanol and to 100 mM in DMSO
>98 %
Store at -20°C
