Herein, the design, synthesis and mechanistic study of five series of imidazo[1,2-a]pyridines 8a-d, 9a-f, 11a-c, 12a-d and 14a-d as anticancer agents were discussed. The cytotoxicity of imidazo[1,2-a]pyridine derivatives was screened against NCI 60 cancer cell lines. The cytotoxicity of compounds 8b, 8c, 9e and 9f was then evaluated against leukemia K-562 cancer cell line and normal lung fibroblasts
本文讨论了5个系列的咪唑并[1,2- a ]吡啶8a-d、9a-f、11a-c、12a-d和14a-d作为抗癌剂的设计、合成和机理研究。针对 NCI 60 癌细胞系筛选了咪唑并[1,2- a ] 吡啶衍生物的细胞毒性。然后评估化合物8b、8c、9e和9f对白血病K-562癌细胞系和正常肺成纤维细胞(WI38)的细胞毒性。腙衍生物8b和8c对白血病 K-562 癌细胞系表现出显着的细胞毒活性,具有良好的安全性(IC 50 = 2.91 µM,SI = 8.32 和 IC 50 = 1.09 µM,SI = 10.54,分别)。此外,测试了化合物8b、8c、9e和9f的EGFR和COX-2抑制活性。腙衍生物8b和8c是最有效的 EGFR 抑制剂,IC 50值分别为 0.123 和 0.072 µM。化合物8c选择性地抑制 COX-2 (IC 50 = 1.09 µM, SI = 13.7
