Used as a selective blocker of voltage-gated potassium channels, particularly Kv7 (KCNQ) channels, in neuroscience research. It enhances neuronal excitability and is applied in studies related to synaptic transmission, epilepsy, and neurodegenerative diseases. Commonly used in electrophysiological experiments to investigate M-current modulation. Also explored for its potential to improve cognitive functions in preclinical models due to its effect on neuronal signaling.
