Biological Activity for Azimilide dihydrochloride

Azimilide dihydrochloride is a Kv11.1 (hERG) channel blocker, blocks rapidly activating and slowly activating components of delayed rectifier K+ currents (IC50 of 0.4 mM and 3 mM, respectively). Also inhibits Na+/Ca2+ exchanger in vitro. Shows inhibition of Na+ currents, L-type Ca2+ currents and other K+ currents at high concentrations.

Azimilide was used to study Kv11.1 channel blocking properties. Kv11.1 channels were being studied to understand the voltage gating mechanism and how the activation and blocking of the channel is different than other Kv channels.
