cell lines (HeLa, K562, LS180, and MCF‐7). Although, all the derivatives were inactive on LS180 cell line, the results on other cells showed that these compounds had weak to moderate antitumoral activities and their IC50 ranged from 25 to >100 µM. Among the synthesized compounds, 7‐(2‐nitrophenyl)‐8,9,10,12‐tetrahydro‐7H‐chromeno[4,3‐b]quinoline‐6,8‐dione (6a) demonstrated the highest activity (IC50 range
在目前的工作中,合成了 15 种带有香豆素环的新型 1,4-二氢吡啶 (DHP),并在 4 种不同的人类癌细胞系(HeLa、K562、LS180 和 MCF-7)上进行了评估。尽管所有衍生物对 LS180 细胞系均无活性,但对其他细胞的结果表明,这些化合物具有弱至中等的抗肿瘤活性,其 IC50 范围为 25 至 > 100 µM。在合成的化合物中,7-(2-硝基苯基)-8,9,10,12-四氢-7H-色诺[4,3-b]喹啉-6,8-二酮(6a)表现出最高的活性(IC50范围在不同的细胞系中:25.4-58.6 µM)。此外,衍生物的钙通道拮抗剂活性(当这些化合物用作抗肿瘤剂时的不良作用)远低于参考拮抗剂硝苯地平。综上所述,
