Selective connexin 43 (Cx43) hemichannel blocker; has no effect on gap junction coupling or Panx-1 channels. Reduces mitochondrial potassium influx in cardiomyocytes and attenuates glutamate-triggered ATP release in primary astrocytes. Modestly reduces infarct size in a mouse ischemia model.

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.
