the interactions of eight piperidine derivatives with nicotinic receptor complexes from torpedo californica electric organ were studied using [ 125i ] alpha-bungarotoxin [ ( 125i ] bgt ) as a probe for the acetylcholine binding site and [ 3h ] perhydrohistrionicotoxin [ ( 3h ] h12-htx ) as a probe for a site associated with the receptor-gated ion channel .
