in‐vitro cytotoxic activity against MDA‐MB‐231 and MCF‐7 human breast cancer cells. Evaluation of the cytotoxicity of 7–12 employing a MTT assay and inhibition of [3H]thymidine incorporation into DNA demonstrated that these compounds exhibit remarkable cytotoxic effects in comparison with 4‐[bis(2‐chloroethyl)amino]benzenebutanoic acid. Compounds 7 and 9, which possess a cationic amidine and 4,5‐dihydro‐1H‐imidazol
新型氮芥剂 7-12 涉及 4-(N,N-双(2-氯乙基)氨基苯基)丙胺通过形成酰胺键连接到 5-(4-N-烷基脒基苯基)-2-呋喃甲酸部分具有合成、表征并评估了它们对 MDA-MB-231 和 MCF-7 人乳腺癌细胞的体外细胞毒活性。使用 MTT 测定和抑制 [3H] 胸苷掺入 DNA 评估 7-12 的细胞毒性表明,与 4-[双(2-氯乙基)氨基]苯丁酸相比,这些化合物表现出显着的细胞毒性作用。化合物 7 和 9 具有阳离子脒和 4,5-二氢-1H-咪唑官能团,其效力大约是 4-[双(2-氯乙基)氨基]苯丁酸的 10 倍。新化合物被评估为 DNA 拓扑异构酶 II 抑制剂。
