Scientific background

4,9-Anhydrotetrodotoxin, also called 4,9-anhydro-TTX, is a derivative of tetrodotoxin, a potent neurotoxin found in a number of marine creatures including the pufferfish. 4,9-Anhydro-TTX acts as a potent and selective NaV1.6 channel blocker with an IC50 value of 7.8 nM1.4,9-Anhydrotetrodotoxin was found to block the activity of NaV1.6 channels with an efficacy of 40-160 times higher than other tetrodotoxin sensitive NaV1.x channel isoforms. The compound successfully prevents the influx of Na+ ions by blocking the pore of the NaV channel from the extracellular side of the plasma membrane2.4,9-Anhydrotetrodotoxin has become a useful pharmacological tool for the investigation and identification of the biophysical properties of NaV1.6 channels2.Voltage-gated sodium (NaV) channels are responsible for initiating action potentials in electrically excitable cells. NaV channels play an important role in human pain signaling pathways and are an important therapeutic target for the treatment of chronic pain. Mutations in NaV channels are also associated with a range of complex pathologic conditions such as epilepsy, myotonic conditions and cardiac arrhythmias3,4.
