Morphine and its nicotinoyl esters, dinicotinoylmorphine (nicomorphine), 6-mononicotinoylmorphine (6-MNM) and 3-mononicotinoylmorphine (3-MNM) were tested in mice for central activity to obtain time-effect profiles of these compounds in rats. Two effects, analgesia with the hot plate test and locomotor stimulation in activity cages were measured and nicomorphine, 6-MNM and 3-MNM were found to have a faster onset of action compared with morphine. The effects of 3-MNM and morphine lasted longer than the effect of nicomorphine and 6-MNM. The prodrug behaviour of 3-MNM and nicomorphine for morphine and 6-MNM, respectively, is discussed.
对吗啡及其烟酰基酯类化合物,即二烟酰基吗啡(尼可吗啡)、6-单烟酰基吗啡(6-MNM)和3-单烟酰基吗啡(3-MNM),在小鼠身上进行中枢活性测试,以获取这些化合物在大鼠体内的时效曲线。通过热板试验测定镇痛效果,在活动笼中测定运动刺激效果,结果发现与吗啡相比,尼可吗啡、6-MNM和3-MNM起效更快。3-MNM和吗啡的作用持续时间比尼可吗啡和6-MNM更长。分别讨论了3-MNM和尼可吗啡对吗啡和6-MNM的前体药物行为。
