2-methyl-4-/5-nitroimidazole derivatives (3 & 4) have been synthesized by K2CO3 catalyzed reaction between 2-methyl-5-nitro-1H-imidazole (1) or metronidazole (2) and acrylonitrile. The derivates were obtained in good yields and characterized by IR spectroscopy, 1H-NMR spectroscopy, and ESI-MS mass spectrometry. Single-crystal X-ray structure analysis supported the formation of the derivatives, which were further
摘要 通过 K2CO3 催化 2-甲基-5-硝基-1H-咪唑 (1) 或甲硝唑 (2) 与丙烯腈反应合成了两种 N-取代的 2-甲基-4-/5-硝基咪唑衍生物 (3 & 4)。 . 以良好的收率获得了衍生物,并通过红外光谱、1H-NMR 光谱和 ESI-MS 质谱进行了表征。单晶 X 射线结构分析支持衍生物的形成,DFT 研究进一步补充了衍生物的形成。还进行了针对人结肠癌细胞系 (SW-480) 的体外抗癌活性。为了支持所报道的衍生物对核酸的亲和力,采用了体外(ct-DNA 结合研究)和计算机内(对接研究)技术。尽管它们的体积小并且存在药理活性核心,但 3 (IC50 > 160 μg/mL,
