Abstract
Binding studies indicate that ciguatoxin and brevetoxin allosterically enhance in a very similar way the binding of [3H]batrachotoxinin A 20-alpha-benzoate to the neuronal Na+ channel protein. Moreover ciguatoxin competitively inhibits the binding of [3H]brevetoxin-3 to rat brain membranes. The affinity of ciguatoxin for the Na+ channel is at least 20-50-times higher than that of brevetoxin. These results indicate that ciguatoxin and brevetoxins act at the same binding site on the sodium channel.Entities:
