To extend our earlier data on synergistic action of tetrahydroisoquinolines and morphine, we have investigated the analgesic effects of 1,2,3,4-tetrahydroisoquinoline (TIQ) and its 1-methyl-(1-MeTIQ) and N-methyl (N-MeTIQ) analogs on analgesia induced by morphine and oxotremorine. 1-MeTIQ and N-MeTIQ induced a moderate, delayed and prolonged analgesic action measured in the tail-flick test in CD-1 mice; 1-MeTIQ and TIQ prolonged the opiate (morphine, 2.5 mg/kg i.p.) analgesia while TIQ and N-TIQ potentiated cholinergic (oxotremorine, 0.02 mg/kg i.p.) analgesia. The involvement of the opioid and noradrenergic systems in this effect is discussed.
为了扩展我们早期关于四氢异喹啉与吗啡协同作用的数据,我们研究了1,2,3,4 - 四氢异喹啉(TIQ)及其1 - 甲基 -(1 - MeTIQ)和N - 甲基(N - MeTIQ)类似物对吗啡和氧化震颤素诱导的镇痛作用。在CD - 1小鼠的甩尾试验中,1 - MeTIQ和N - MeTIQ诱导了中度、延迟和延长的镇痛作用;1 - MeTIQ和TIQ延长了阿片类药物(吗啡,2.5mg/kg腹腔注射)的镇痛作用,而TIQ和N - TIQ增强了胆碱能(氧化震颤素,0.02mg/kg腹腔注射)的镇痛作用。本文讨论了阿片类和去甲肾上腺素能系统在这种作用中的参与情况。
