5-dimethoxyacetophenone. A number of novel pyridines 2a–j, 3, 4, thiophenes 5–9 and thiazoles 10–12 were prepared by using the hydrazide-hydrazone derivative 1 as a starting material. The structure of the newly synthesized compounds was characterized by elemental analyses, IR, 1H-NMR, 13C-NMR and mass spectral data. All the target compounds were subjected to in vitro antitumor activity against Ehrlich Ascites Carcinoma
摘要 以氰基乙酸酰肼与2,5-二甲氧基苯乙酮反应制得2-氰基-N'-[1-(2,5-二甲氧基苯基)]亚乙基乙酰肼1。通过使用酰肼 - 腙衍生物 1 作为起始材料,制备了许多新型吡啶 2a-j、3、4、噻吩 5-9 和噻唑 10-12。新合成化合物的结构通过元素分析、IR、1H-NMR、13C-NMR和质谱数据表征。所有目标化合物均具有抗艾氏腹水癌(EAC)细胞的体外抗肿瘤活性。与参考药物 IC50 值 (68.99 μM) 相比,化合物 2j 和 6 显示出更高的活性,IC50 值 (54.54, 61.57 μM) 为 8,而化合物 5 的活性几乎与阿霉素 (CAS 23214-92-8) 一样。
