Common NameAnhydrotetrodotoxin
DescriptionAnhydrotetrodotoxin is a member of the chemical class of voltage-gated sodium channel (VGSC) inhibitors, specifically a structural analog of tetrodotoxin. Its chemical structure features a unique arrangement that allows it to selectively block sodium currents mediated by specific VGSC subtypes, particularly Nav1.6, while showing reduced activity against others like Nav1.2 and Nav1.3. Anhydrotetrodotoxin has been shown to reduce sodium current in various neuronal preparations, influencing action potential characteristics and calcium influx during neuronal firing (PMID:30487736 ). This compound operates within the context of neuronal signaling pathways, where it modulates excitability by inhibiting sodium channels, thus affecting neurotransmitter release and synaptic transmission. In experimental models, 4,9-anhydrotetrodotoxin has been used to demonstrate the role of Nav1.6 in shaping action potentials and has been implicated in the differential expression of sodium channel subunits in various neuronal types (PMID:36946031 , PMID:32273850 ). Its selectivity for Nav1.6 over other VGSCs highlights its potential utility in research focused on neuronal excitability and the pharmacological modulation of sodium channels (PMID:32114117 ).
