Inhibitor of the reverse mode of Na+/Ca2+ exchange (NCX). Potently inhibits Na+-dependent 45Ca2+ uptake (IC50 values are 18, 68 and 96 nM for CCL39 cells transfected with NCX3, NCX1 and NCX2 respectively). Displays selectivity for NCX over other Na+ and Ca2+ transporters. Protects against hypoxia/reoxygenation-induced cell damage in neuronal SH-SY5Y cells expressing NCX1 and NCX3.

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.
