lack of practical methods for the synthesis of such analogues has limited this effort. Here, we present a concise synthetic approach to N-substituted phenanthropiperidines, which enabled a systematic investigation of structure-activity relationships at an underexplored region of the tylophorine scaffold. This work suggests that ring E of tylophorine is essential for the anti-proliferative activity of the
tylophorine和许多相关的phenththropiperidine生物碱是非常有效的抗增殖剂。尽管它们具有令人印象深刻的抗癌活性,但这些生物碱的不良溶解性和神经系统副作用阻碍了它们的临床开发。尽管已经提出开发极性菲咯烷吡啶类极性物质将减轻这些不希望的性质,但是缺乏合成此类类似物的实际方法限制了这种努力。在这里,我们为N提供了一种简洁的综合方法-取代的菲咯烷啶,可系统地研究酪氨酸骨架的未充分研究区域的结构-活性关系。这项工作表明,酪氨酸环E对6,7,10,11-四甲氧基-1,2,3,4-四氢二苯并[ f,h ]异喹啉核心骨架的抗增殖活性至关重要。
