benzimidazole-2-carboxamide as was previously reported. The structure of the obtained quinoxaline has been confirmed by X-ray. The anti-tumor activity of synthesized quinoxalines 1–21 has been evaluated by studying their possible inhibitory effects on Epstein–Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). Among the studied compounds 1–21, compounds 12, 8,
对邻苯二胺和草酸乙酯的反应进行了重新研究,并导致了3-氨基喹喔啉-2(1 H)-一,而不是如先前报道的苯并咪唑-2-甲酰胺。所获得的喹喔啉的结构已经通过X射线确认。合成喹喔啉的抗肿瘤活性1 - 21已经通过研究Epstein-Barr病毒通过12-诱导的早期抗原(EBV-EA)激活它们的可能抑制效果评价ö -tetradecanoylphorbol -13-乙酸酯(TPA)。在所研究的化合物1 - 21,化合物12,8,13,18,17图3和图19分别显示了对EBV-EA活化的强抑制作用,而没有显示任何细胞毒性,并且它们的作用比代表性的对照齐墩果酸强。此外,化合物12显示出在皮肤上的肿瘤促进显着的抑制效果在体内使用7,12-二甲基苯并[两级小鼠皮肤癌测试一个]蒽(DMBA)作为引发剂和TPA作为促进剂。本研究的结果表明,化合物12作为有效的癌症化学预防剂可能有价值。此外,已经完成了分子对接
