Kv7 channel activators decrease neuronal excitability and might potentially treat neuronal hyperexcitability disorders like epilepsy and mania. Here we introduce NS15370 ((2-(3, 5- difluorophenyl)-N-[6-[(4-fluorophenyl) methylamino]-2-morpholino-3-pyridyl] acetamide) hydrochloride, an in vitro high-potency chemical analogue of retigabine, without effects on GABAA receptors. NS15370 activates recombinant homo-and heteromeric Kv7. 2–Kv7. 5 ...
