Atrial natriuretic peptide antagonists: biological evaluation and structural correlations.

abstract：:Batrachotoxin (BTX), from South American frogs of the genus Phyllobates, irreversibly activates voltage-gated sodium channels. Previous work demonstrated that a phenylalanine residue approximately halfway through pore-lining transmembrane segment IVS6 is a critical determinant of channel sensitivity to BTX. In this st...
