cytotoxic activity of the synthesized compounds was evaluated against normal EA.HY926 cells and five cancer cell lines: LLC (Lewis lung carcinoma), BGC-823 (gastric carcinoma), CT-26 (murine colon carcinoma), Bel-7402 (liver carcinoma), and MCF-7 (breast carcinoma). Compound 10e, with an IC50 value of 2.41 μM against EA.HY926 cells, was the most potent inhibitor. It showed cytotoxicity against all five
设计了一系列由N-酰基hydr连接的异二价β-咔啉衍生物,并按九步反应顺序由1-色氨酸合成。该努力导致了高收率的异二价β-咔啉10a-t。目标化合物通过1H NMR,13C NMR和高分辨率质谱(HRMS)进行表征。评估了合成化合物对正常EA.HY926细胞和5种癌细胞系的体外细胞毒性活性:LLC(刘易斯肺癌),BGC-823(胃癌),CT-26(鼠结肠癌),Bel-7402 (肝癌)和MCF-7(乳腺癌)。化合物10e对EA.HY926细胞的IC50值为2.41μM,是最有效的抑制剂。它对鼠类和人类这五种不同来源的癌细胞系均显示出细胞毒性,IC50值为4.2±0。7至18.5±3.1μM。对结构-活性关系的研究表明,R9'-位对取代基的细胞毒性活性的影响遵循2,3,4,5,6-全氟苯基甲基> 4-氟苄基> 3-苯基丙基的趋势。还在小鼠中评估了所选化合物的抗肿瘤功效。化合物10e表现出有效
