Biological Activity

[Description]:

4,9-Anhydrotetrodotoxin is a selective voltage-gated sodium channel (VGSC) inhibitor that blocks Nav1.1 and Nav1.6 in human brain and induces a hyperpolarizing shift in the voltage dependence of inactivated Nav1.6[1].

[In Vitro]

4,9-Anhydrotetrodotoxin (0.01-10000 nM) results in significant blockade of Nav1.6-mediated Na current in the nanomolar range, it also has significant effects on Nav1.1-mediated Na current in human brain sample[1].
