Benzo[c]phenanthrolines and benzo[c]phenanthrolinones substituted by dialkylaminoalkyl side chains at position N5 and C6, respectively, were synthesised and their biological activity evaluated. They displayed interessant cytotoxicity associated with some DNA interactions. However, the low topoisomerase 1 affinity suggests that other cellular targets are responsible for the antiproliferative activity
分别合成了在位置N5和C6处被二烷基氨基烷基侧链取代的苯并[ c ]菲咯啉和苯并[ c ]菲咯啉酮,并对其生物学活性进行了评估。他们表现出与某些DNA相互作用有关的间质细胞毒性。但是,低的拓扑异构酶1亲和力表明其他细胞靶标负责抗增殖活性。
Synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8] phenanthrolin-(5H)-6-ones through a Pd-mediated Suzuki–Miyaura heteroaryl-aryl coupling reaction
In the course of the search for non-camptothecin topoisomerase I inhibitors we have undertaken the synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8]phenanthrolinone derivatives. An intermolecular Suzuki–Miyaura heteroaryl-aryl coupling reaction was planned as the key step. Then a nitro reduction followed by a concomitant lactamization achieved the construction of the tetracycle structures
在寻找非喜树碱拓扑异构酶I抑制剂的过程中,我们进行了N-取代的苯并[ c ] [1,7]-和苯并[ c ] [1,8]菲咯啉酮衍生物的合成。分子间的铃木-宫浦杂芳基-芳基偶联反应被计划为关键步骤。然后硝基还原,随后伴随内酰胺化,实现了四环结构的构建。这种方法可以快速有效地制备生物有效的化合物。
