Biological Activity for Gap 26
Gap 26 is a peptide, corresponding to residues 63 - 75 of connexin 43, which is a gap junction blocker. Attenuates rhythmic contractile activity of rabbit arterial smooth muscle (IC50 = 28.4 μM). Also inhibits IP3-induced ATP release, without inhibiting gap junctional coupling in endothelial cells.

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.
