antitumor drugs, a series of substituted N-[2-(dimethylamino)ethyl]phenazine-1-carboxamides have been synthesized and evaluated. Fluorine-directed ring closure of N-phenyl-3-nitroanthranilic acids provided a new, unequivocal synthesis of several of the required phenazine-1-carboxylic acids, and the corresponding carboxamides were prepared and evaluated against L1210 leukemia in vitro and against P388
hydrazone compounds 3a–3j were obtained by the condensation reaction of phenazine-1-carboxylic acid hydrazide and the respective aldehyde-containing compound. The structures were characterized by 1H and 13C NMR spectroscopy, MS and single crystal X-ray diffraction. The antitumor activity of the target compounds in vitro (HeLa and A549) was determined by thiazolyl blue tetrazolium bromide. The results showed
吩嗪-1-羧酸中间体由苯胺和2-溴-3-硝基-苯甲酸反应合成。然后将其酯化并与水合肼反应以提供吩嗪-1-羧酸肼。最后,通过吩嗪-1-羧酸酰肼与相应的含醛化合物的缩合反应,得到了10个新的腙化合物3a - 3j。通过1 H 和13 C NMR 光谱、MS 和单晶 X 射线衍射表征结构。目标化合物(HeLa和A549)的体外抗肿瘤活性通过噻唑蓝四唑溴化物测定。结果表明化合物( E ) -N'-(2-hydroxy-4-(2-(piperidine-1-yl) ethoxy) benzyl) phenazine-1-carbonyl hydrazide 3d表现出良好的细胞毒活性。
