morphinanone agonists differently substituted at C(3), C(4), C(5) and C (14) and antagonists of the 4-hydroxy and 3, 4-dimethoxy series were prepared by conventional chemistry. It was demonstrated that the oxygenation pattern in the bay-area, encompassing C(3) and C(4), is important. Alkylation at C(5) or hydroxylation at C(14) lowered the potency of the compounds. The most potent agonist was found to
通过常规化学方法制备了几种在C(3),C(4),C(5)和C(14)处不同取代的吗啡酮激动剂以及4-羟基和3,4-二甲氧基系列的拮抗剂。事实证明,海湾区域的氧化模式非常重要,包括C(3)和C(4)。C(5)处的烷基化或C(14)处的羟基化降低了化合物的效力。发现最有效的激动剂是N-苯乙基取代的酮27,其在热板测定中的效力是吗啡的六倍。3,4-亚甲基二氧基取代的酮9的效力比其3,4-二甲氧基同类物低约20倍。X射线分析9 且有代表性的激动剂表明,海湾地区的立体化学特征相似,因此不能用来解释这种差异。
