hydrazide–hydrazone derivatives. Unfortunately, all test compounds, as well as doxorubicin, showed no cytotoxicity toward drug-resistant cell line, Caco-2. Our preliminary results indicated that coumarin hydrazide–hydrazone derivatives could be exploited as leading structures for further anticancer-drug development.

摘要 设计,合成和评估了一系列21种香豆素酰肼-hydr衍生物,并在体外以25μg/ mL的浓度评估48 h对肝癌(HepG2)细胞系的潜在细胞毒性作用。然后,从21种化合物中筛选出7种细胞存活率低于60%的化合物,以评估其对肝癌(HepG2),乳腺癌(SKBR-3)和人结肠癌(Caco-2)细胞的体外抗增殖活性线。在测试化合物中,5g,6d和6f对Hep-G2和SKBR-3细胞系均显示出有效的活性。更重要的是,具有4-溴苯基部分的化合物6d对IC 50表现出对Hep-G2细胞系的最佳细胞毒性活性值2.84±0.48μg/ mL,与标准阿霉素相当(IC 50 = 2.11±0.13μg/ mL)。此外, 与其他经测试的香豆素酰肼-hydr衍生物相比,具有4-甲氧基苯基部分的化合物6f对SKBR-3细胞系表现出最强的活性(IC 50 = 2.34±0.68μg/ mL)。不幸的是,所有测试
