been explored. Optimal muscarinic agonist activity was observed for unsubstituted pyrazines in the azanorbornane series. The exo-1-azanorbornane 18a is one of the most efficacious and potent centrally active muscarinic agonists known. Studies on the 3-substituted derivatives have provided evidence of the preferred conformation of these ligands for optimal muscarinicactivity. Substitution at C6 gave
