The affinity of 1-(6-chloro-5-methoxy-3-pyridyl)-homopiperazine fumaric acid salt for nicotinic Ach receptors was investigated in a test for in vitroinhibition of 3H-cytisine binding. The compound exhibited and IC 50value of 0.0007 mu M. MECHANISM OF ACTION : Nicotinic acetyl choline receptor ligand.
