A series of novel chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) were designed, synthesized and their structures were confirmed by 1H NMR, 13C NMR and mass spectral data. Further, all derivatives were tested for their anticancer activities against five human cancer cell lines such as MCF-7 (breast cancer), A-549 (lung cancer), Colo-205 (colon cancer), A2780 (ovarian cancer) and DU-145
设计,合成了一系列新型查耳酮衍生物吡啶并[4,3-b]吡嗪-5(6H)-one (10a-j),并通过1 H NMR,13 C NMR和质谱数据证实了其结构。此外,测试了所有衍生物对五种人类癌细胞系(例如MCF-7(乳腺癌),A-549(肺癌),Colo-205(结肠癌),A2780(卵巢癌)和DU- 145(前列腺癌),采用MTT分析。将临床使用的药物依托泊苷用作标准参考,抗癌活性表示为IC 50,单位为µM。在所检查的十种化合物中,化合物10b,10c,10d,10h和10i具有更强的抗癌活性。进行了一个分子对接研究,暗示了ATR激酶在ATR激酶的活性位点上观察查尔酮衍生物吡啶并[4,3 - b ]吡嗪-5(6 H)-one (10a-j)的结合方式。最有希望的化合物10h显示π-π 三甲氧基苯基和吡啶酮部分与残基Trp850的堆积相互作用,而羰基(α,β-不饱和羰基)和甲氧基官能团分
