metabisulfite or sodium hydrosulfite under microwave irradiation. The new benzimidazole derivatives were screened for their cytotoxic activity against the human breast cancer cell line (MCF-7). The results showed on one hand that 2-(substituted quinolizinyl)-1H-benzimidazoles (12b–f) were less active (3–6 fold) than the positive control Tamoxifen (CC50 = 6.52 μM), and on the other hand, among the 2-(substituted
通过缩合反应合成了十二种具有5位和6位取代基(氮杂,H,CH 3,Cl,NO 2,NH 2,OCH 3)的2-喹啉嗪基苯并咪唑衍生物和2-萘基苯并咪唑衍生物。焦亚硫酸钠或亚硫酸氢钠在微波辐射下,用取代的邻苯二胺,邻硝基苯胺和2,3-吡啶二胺制备4-氧代-4 H-喹啉嗪甲醛或萘甲醛。筛选新的苯并咪唑衍生物对人乳腺癌细胞系(MCF-7)的细胞毒活性。结果一方面表明2-(取代的喹啉嗪基)-1 H-苯并咪唑(12b – f)的活性(3-6倍)比阳性对照他莫西芬(CC 50 = 6.52μM)低,另一方面,在2-(取代萘基)-1 H-苯并咪唑系列中(13a – f),化合物6,7,8-三甲氧基-3-(5-氯-1 H-苯并[ d ]咪唑-2-基)萘-1-醇(13c)(CC 50 = 7.48μM)和发现6,7,8-三甲氧基-3-(5-甲氧基-1 H-苯并[ d ]咪唑-2-基)萘-1-醇(13f)(CC
