Potent and selective inhibitor of human NaV1.3 and NaV1.1 channels (IC50 values are 13 and 23 nM respectively). Exhibits up to 1,000 fold selectivity against other TTX-sensitive or resistant sodium channels (IC50 values are >10 μM for human NaV1.5 and NaV1.8 channels). Interacts with an inhibitory interaction site distinct from those bound by TTX and local anesthetic-like modulators.

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.
