The compounds revealed high antiproliferative activity in vitro in the breast cancer cell line MDA-MB-231 and hepatocellular carcinoma cell line LM3 in the low micromolar to nanomolar concentration range. Important structure–activity relationships were deduced from the comparison of anticancer activities of HL1–HL4 and 1–4 with those of structurally similar paullone-derived (HL5–HL7 and 5–7) and latonduine-derived
Indolo[3,2- d ][1]benzazepines (paullones)、indolo[3,2 - d ][2]benzazepines 和 indolo[2,3- d ][2]benzazepines (latonduines) 是目前药用兴趣。在此,我们制备了一个小型的新型吲哚[3,2 - d ][2]苯并氮杂衍生配体HL 1 – HL 4和铜 (II) 配合物1 – 4库。所有化合物均通过光谱方法(1 H 和13 C NMR、UV-vis、IR)和电喷雾电离 (ESI) 质谱法进行表征,而配合物2和3,此外,通过 X 射线晶体学。它们的纯度通过 HPLC 结合高分辨率 ESI 质谱和/或元素分析来确认。通过1 H NMR 和 UV-vis 光谱测量证实了化合物在 DMSO 存在下在水溶液中的稳定性。这些化合物在低微摩尔至纳摩尔浓度范围内对乳腺癌细胞系 MDA-MB-231
