Chemical Name: N-[3,5-Bis(trifluoromethyl)phenyl]-N'-[2,4-dibromo-6-(2H-tetrazol-5-yl)phenyl]urea

Biological Activity

KV4.3 channel activator; mediates the transient outward K+ current (Ito). Increases IKv4.3 peak current amplitude in CHO-K1 cells expressing KV4.3 and KChIP2 (EC50 = 5.3 μM). Inhibits KV1.4-mediated currents independently of KChIP2. Also slows the decay of KV4.2 and KV4.3 currents in the presence of KChIP2.

Technical Data

Soluble to 100 mM in DMSO and to 50 mM in ethanol
>99 %
Store at +4°C
