Biological Activity for Veratridine
Veratridine is a voltage-gated Na+ channel opener; increases intracellular Ca2+ with no effect on the Na+/Ca2+ exchanger. Steroid-derived alkaloid neurotoxin. Increases membrane Na+ permeability and depolarizes excitable tissues.

Can be used to activate and open voltage sensitive sodium channels in neurons. Elicits rapid reaction when applied directly to tissue.
Verstridine is a voltage-gated sodium channel agonist. It increases intracellular Na+ concentration and also induces cellular and tissue swelling. We used at 50 microM to rat brain slices.

Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
