arrhythmic activity and also higher toxicity. A series of derivatives were synthesized by using three kinds of aporphine alkaloids (crebanine, isocorydine, and stephanine) as lead compounds. Chemical methods, including ring-opening reaction, bromination, methylation, acetylation, quaternization, and dehydrogenation, were adopted. Nineteen target derivatives were evaluated for their antiarrhythmic potential
发现一些甲啡碱生物碱,例如克巴宁,具有心律不齐的活性,并且毒性更高。通过使用三种阿波啡生物碱(甲骨碱,异丁烯碱和Stephanine)作为先导化合物,合成了一系列衍生物。化学方法包括开环反应,溴化,甲基化,乙酰化,季铵化和脱氢。在由CHCl 3诱发的心室纤颤(VF)小鼠模型中评估了19种目标衍生物的抗心律失常潜力,并在由BaCl 2诱发的心律不齐的大鼠模型中进一步研究了其中5种衍生物。同时,进行了初步的结构-活性/毒性关系分析。值得注意的是,N-乙酰胺西异crebcrebanine(1d),三个溴取代的crebanine产物(2a,2b,2c),在CHCl 3诱导的模型中,N-甲基crebanine(2d)和dehydrostephanine(4a)显示出抗心律失常作用。其中7.5 mg / kg的2b能够显着降低CHCl₃诱发的VF发生率(p <0.05),增加由BaCl 2诱发的由心律失常恢复窦性心律的大鼠的数量(p
