corresponding 12H-benzo[b][1,7]phenanthrolin-7-ones 14 and 15, and 12H-benzo[b][1,10]phenanthrolin-7-ones 16-18. Compounds 14, 16, and 17 were subsequently N-methylated to 6-demethoxyacronycine and acronycine analogues 19-21, whereas reduction of the aromatic nitro group of 18 gave the amino derivative 22. Unsubstituted 12H-benzo[b][1,10]phenanthrolin-7-ones 16, 17, 20, and 21 were devoid of significant
2-溴苯甲酸(4)或2-氯-3-硝基苯甲酸(5)与合适的氨基喹啉6-8缩合,得到苯基喹啉胺9-13。酸介导的环化反应产生相应的12H-苯并[b] [1,7]菲咯啉-7-酮14和15,以及12H-苯并[b] [1,10]菲咯啉-7-酮16-18。随后将化合物14、16和17 N-甲基化为6-去甲氧基精胺和丙烯醛类似物19-21,而还原18的芳族硝基得到氨基衍生物22。未取代的12H-苯并[b] [1,10]菲咯啉7-,16、17、20和21没有明显的细胞毒活性,而18和22(在11位带有氮取代基)则具有明显的细胞毒性。未取代的12H-苯并[b] [1,7]菲咯啉-7-酮14和19,
