Biological Activity
Potent and selective blocker of KV7 (KCNQ) voltage-gated potassium channels. Blocks KV7.2+7.3 (KCNQ2+3) / M-currents (IC50 = 0.6 - 0.98 μM) and KV7.1 (KCNQ1) homomeric channels (IC50 = 0.75 μM) but is less potent against KV7.1/minK channels (IC50 = 11.1 μM). Augments hippocampal ACh release and is a cognitive enhancer following oral administration in vivo.
