Sulfide analogues were identified that are devoid of the risk of quinone formation, but possess potent KV 7.2/3 opening activity. For example, flupirtineanalogue 3-(3,5-difluorophenyl)-N-(6-(isobutylthio)-2-(pyrrolidin-1-yl)pyridin-3-yl)propanamide (48) has 100-fold enhanced activity (EC50 =1.4 nm), a vastly improved toxicity/activity ratio, and the same efficacy as retigabine in vitro.

The present application discloses novel substituted 1,4-oxazepanyl-pyridine derivatives and their use as modulators of the voltage gated KV7 (KCNQ) potassium ion channels. In other aspects the application discloses the use of these compounds, in a method for therapy and to pharmaceutical compositions comprising these compounds.
