Selective blocker of NaV1.8 channels (IC50 values are 8, 2450, 6740, 7340 and 7380 nM for hNaV1.8, hNaV1.3, hNaV1.7, hNaV1.5 and hNaV1.2 channels respectively). Shows no significant activity against TRPV1, P2X2/3, CaV2.2 and KCNQ2/3 channels. Antinociceptive; potently attenuates mechanical allodynia in two models of neuropathic pain following i.p. administration.

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.
