5-epoxy-14-hydroxy-N-methyl-morphinan-6-one (3)>4, 14-dihydroxy-N-methylmorphinan-6-one (4)>14-hydroxy-4-methoxy-N-methylmorphinan (11) ≈4, 14-dihydroxy-N-methylmorphinan (12). The most potent compound in this series, 14-hydroxy-4-methoxy-N-methyl-morphinan-6-one (5), was found to have about six times the potency of morphine; it was equipotent with levorphanol.
描述了使用羟吗啡酮(= 3,14-二羟基-4,5-环氧-N-甲基吗啡喃-6-one,1)作为起始原料合成几种14-羟基吗啡喃的方法。测定了N-甲基取代的14-羟基吗啡喃的抗伤害感受力。因此,按照抗伤害力的顺序,14-羟基-4-甲氧基-N-甲基吗啡喃-6- (5)> 4,5-环氧-14-羟基-N-甲基吗啡喃-6-(3)> 4,14二羟基ñ -methylmorphinan -6-酮(4)> 14-羟基-4-甲氧基ñ -methylmorphinan(11)≈4,14二羟基ñ -methylmorphinan(12)。发现该系列中最有效的化合物14-羟基-4-甲氧基-N-甲基-吗啡喃-6-一(5)的功效约为吗啡的六倍;最强的化合物是吗啡。它与左啡烷等效。
