indole-pyrazoline hybrid derivatives were designed, synthesized, and evaluated for topoisomerase 1 (Top1) inhibitory activity. Top1-mediated relaxation assays showed that our synthesized compounds had variable Top1 inhibitory activity. Among these compounds, 3-(5-(naphthalen-1-yl)-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl)-1-(phenylsulfonyl)-1H-indole (6n) was found to be a strong Top1 inhibitor with better inhibitory
设计,合成和评估了一系列新型的吲哚-吡唑啉杂合衍生物的拓扑异构酶1(Top1)抑制活性。Top1介导的弛豫分析表明,我们合成的化合物具有可变的Top1抑制活性。在这些化合物中,发现了3-(5-(萘-1-基)-1-苯基-4,5-二氢-1H-吡唑-3-基)-1-(苯磺酰基)-1H-吲哚(6n)成为强力的Top1抑制剂,具有比CPT和命中化合物更好的抑制活性。我们的进一步实验合理化了这种新型抑制剂的作用方式,该抑制剂未显示与超螺旋DNA的显着结合。
