The reduction of 5-hydroxytryptamine (5-HT) in rat brain 3 h after administration of 3,4-methylenedioxymethamphetamine (MDMA) was attenuated significantly by coadministration of benzylpiperazine derivatives (p-nitrobenzylpiperazine, p-chlorobenzylpiperazine and 1-piperonylpiperazine), which were weak inhibitors of [3H]5-HT uptake into rat brain synaptosomes. However, the coadministration of desipramine and imipramine which were more potent 5-HT uptake inhibitors than these benzylpiperazines, did not attenuate the reduction of 5-HT by MDMA. These results suggest that these benzylpiperazines might inhibit the acute effects of MDMA by a novel neuropharmacological effect other than 5-HT uptake inhibition.
在给予3,4-亚甲基二氧甲基苯丙胺(摇头丸)3小时后,大鼠脑内5-羟色胺(5-HT)的减少,通过共同给予苄基哌嗪衍生物(对硝基苄基哌嗪、对氯苄基哌嗪和1-胡椒基哌嗪)而显著减弱,这些衍生物是[3H]5-HT进入大鼠脑突触体摄取的弱抑制剂。然而,共同给予比这些苄基哌嗪更强效的5-HT摄取抑制剂地昔帕明和丙咪嗪,并没有减弱摇头丸引起的5-HT减少。这些结果表明,这些苄基哌嗪可能通过5-HT摄取抑制以外的新神经药理学作用来抑制摇头丸的急性效应。
