codeinone was additionally verified by X‐ray crystallography. Compounds 5a, 8, 11a, and 16 have been evaluated for their affinity at μ and κ opioid receptors in radioligand binding assays. Their ability to inhibit [3H]DAMGO binding at μ and [3H]U 69.593 binding at κ receptors, respectively as compared to codeine has been found to be lower.
已经通过各种 3,6-二取代的 1,2,4,5-四嗪与衍生自二氢可待因酮的烯胺和可待因酮的逆电子需求 Diels-Alder 反应合成了许多新型哒嗪吗啡喃。一些哒嗪吗啡喃的还原没有提供预期的吡咯并环氧吗啡喃;在所有研究的情况下,观察到环氧桥的还原裂解产生二氢哒嗪或吡咯并吗啡喃。所有新化合物的结构均由光谱数据指定,可待因酮环加合物的结构另外通过 X 射线晶体学验证。已在放射性配体结合试验中评估了化合物 5a、8、11a 和 16 对 μ 和 κ 阿片受体的亲和力。它们抑制 [3H] DAMGO 在 μ 和 [3H] U 69.593 与 κ 受体结合的能力,
