Abstract

Noxiustoxin from the Mexican scorpion (Centruroides noxius Hoffmann) is known to block neuronal K+ channels. Noxiustoxin facilitated acetylcholine release in chick biventer cervicis nerve-muscle preparations, but not in mouse phrenic nerve-hemidiaphragm preparations. Noxiustoxin displaced binding of a radiolabelled dendrotoxin from synaptosomal membranes from rat brain, with a Ki of 10(-10) M. It is concluded that noxiustoxin shares some pharmacological properties with the K+ channel blocking dendrotoxins.
