  Functionally selective M1 muscarinic agonists. 3. Side chain and azacycles contributing to functional muscarinic selectivity among pyrazinylazacycles

  摘要：

  In an attempt to improve upon the M(1) agonist activity of the selective M(1) agonist xanomeline and related compounds, the M(1) muscarinic efficacies and potencies of 3- and 6-substituted pyrazinylazacycles were varied by changing both the 3- and 6-substituents as well as the azacycle. Significant improvements in efficacy and potency over the previously prepared [3-(hexyloxy)pyrazinyl]tetrahydropyridine 19 were obtained with the [3-(hexyloxy)pyrazinyl]quinuclidine 5i. The M(1) activity of 5i showed some enantioselectivity with (S)-5i being ca. 4-fold more potent than (R)-5i. Like 19 and xanomeline, 5i was a functionally selective M(1) agonist that showed greater functional selectivity than widely studied pyrazinylquinuclidine 5n (L-689,660). The improved functional selectivity of 5i over 5n could be attributed to the additional binding interactions between the hexyloxy side chain of 5i and the M(1) receptor that are not available to 5n. Although 5i may show M(1) functional selectivity comparable to xanomeliine, 5i is a less efficacious and potent M(1) agonist than xanomeline.
