analogues were synthesized and evaluated for inhibition of
binding at nicotine acetylcholine receptors and for antinociceptive properties in mice. The introduction of a bulky phenyl
group at the 3‘-position exerted a profound influence on both
receptor binding and antinociceptive effects. Substitution of
different groups at the 2‘-position distinguished between
agonist and antagonist properties. These results demonstrate
that structural requirements for receptor activities and recognition are distinctively different.
