  Benzofuro[2,3-c]pyridin-6-ols: synthesis, affinity for opioid-receptor subtypes, and antinociceptive activity

  摘要：

  A general synthetic approach to a novel series of cis-1,2,3,4,4a,9a-hexahydrobenzofuro[2,3-c]pyridin-6-ols is described together with their receptor-binding profile on opioid-receptor subtypes (mu, kappa, delta). In addition, their in vivo antinociceptive activity was assessed. A number of the analogues synthesized showed potent affinity for opioid receptors and have potent antinociceptive activity in a mouse phenylquinone abdominal stretching model. In addition, the SAR for nitrogen substitution in the above series is explored with respect to the overall opioid receptor subtype binding profile. In general it was found that substituents which enhanced mu and kappa binding affinity in the benzomorphan series had a similar effect in the benzofuropyridine series described in this manuscript. An overlap hypothesis topologically connecting the benzomorphan nucleus to the cis-1,2,3,4,4a,9a-hexahydrobenzofuro[2,3-c]pyridine nucleus is also presented.

  Enantiomers of N-substituted benzofuro[2,3-c]pyridin-6-ols have been synthesized, and the subnanomolar affinity and potent agonist activity of the known racemic N-phenethyl substituted benzofuro[2,3-c]pyridin-6-ol can now be ascribed to the 4aS,9aR enantiomer. The energy-minimized structures suggest that the active enantiomer bears a greater three-dimensional resemblance to morphine than to an ostensibly
