Biological Data

Biological description Kv7 channel blocker. Increases ACh release in the brain and blocks M currents (IC50 = 2.4 µM). Induces increased neocortical Fos protein expression in aged rats. Also agonises TRPV1 (transient receptor potential vanilloid type 1) channel. Shows excitatory actions on nociceptors and shows cognition enhancing actions.
