1,10-Phenanthroline has been shown to exhibit anticancer activity. Here, a series of imidazo [4,5f][1,10] phenanthroline derivatives 1−10 were synthesized and their biological activities were further elucidated. We found that 2-(4-Brominephenyl)-imidazo [4,5f][1,10] phenanthroline (compound 3) possessed potent antiproliferation activities again a variety of tumor cell lines using 3-(4,5-dimethyl-2-thiazolyl)-2
1,10-菲咯啉已显示出抗癌活性。在这里,合成了一系列咪唑并[4,5 f ] [1,10]菲咯啉衍生物1-10,并进一步阐明了它们的生物学活性。我们发现2-(4-溴苯基)-咪唑并[4,5 f ] [1,10]菲咯啉(化合物3)在使用3-(4,5-二甲基-2 -噻唑基)-2,5-二苯基溴化四氮唑(MTT)分析。流式细胞仪分析显示,化合物3通过人肺腺癌细胞系A549的凋亡和坏死诱导。此外,化合物3这种治疗导致A549细胞中IκBα的上调以及p65和c-myc的下调。综上所述,这些结果表明化合物3通过抑制NF-κB活性和下调c-myc基因表达来抑制细胞增殖,并且可能作为人癌症,尤其是肺癌的化学预防和化学治疗剂而进一步评估的候选者。癌症。
