| pubmed-article:1920124 | pubmed:abstractText | Anatoxin analogs were designed to evaluate the importance of H-bonding, planarity, size and steric configuration of the anatoxin side chain moiety with regard to nicotinic potency and efficacy. This report examines the actions of these analogs on the somatic nicotinic acetylcholine receptor at two different loci: the agonist recognition site and the ion channel site. Agonist effects were evaluated using stimulation of contracture and radioligand binding competition for [125I]alpha bungarotoxin sites in Rana pipiens muscle, and stimulation of [3H]perhydrohistrionicotoxin binding and competition for [125I]alpha bungarotoxin sites in Torpedo californica electric organ. Antagonist effects were evident in the inhibition of neurally evoked twitch of the frog sciatic nerve-sartorius muscle preparation and in inhibition of [3H]perhydrohistrionicotoxin binding to Torpedo receptors. The affinity of these analogs for the agonist locus was consistently associated with activation of the AChR. Our results show that side chain steric configuration has an important role in affinity of the (+)-anatoxin-a analogs for the nicotinic acetylcholine receptor ion channel sites. Several analogs also revealed stereospecific noncompetitive actions. The (+)-anatoxin-a-related structures are important probes for characterizing both agonist and ion channel target sites on the peripheral nicotinic receptor. | lld:pubmed |
