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
N-取代的苯并呋喃[2,3 - c ]pyridin-6-ols的对映异构体已经合成,已知的外消旋N-苯乙基取代的苯并呋喃[2,3 - c ]pyridin-6-具有亚纳摩尔亲和力和有效的激动剂活性。ol 现在可以归因于 4a S ,9a R对映异构体。能量最小化的结构表明活性对映体与吗啡的三维相似性比表面上结构相似的氧化物桥接苯基吗啡更相似。比较了 N-取代的苯并呋喃 [2,3 - c ]pyridin-6-ol的构象异构体的结构特征,以提供其结合亲和力的基本原理。
