Effect of a 6-Cyano Substituent in 14-Oxygenated N-Methylmorphinans on Opioid Receptor Binding and Antinociceptive Potency
摘要:
In a continued effort to find new substitution patterns in morphinans that would produce strong antinociception while inducing lesser side effects, 4,5-oxygen bridge-opened 6-cyano-substituted N-methylmorphinans (1-3) were synthesized. All compounds showed high affinities in the low nanomolar range to the mu opioid receptor and decreased interaction with delta and kappa receptors, thus being mu selective. When tested in vivo, the 6-cyanomorphinanas acted as potent antinociceptive agents which were either more active or equipotent to their 6-keto analogues 4-6.
