Polar phenanthrene-based tylophorine derivatives (PBTs) were designed, synthesized and evaluated as potential antitumor agents. These compounds contain a core phenanthrene structure and can be synthesized efficiently in excellent yield. The newly synthesized PBTs were evaluated for cytotoxic activity against the A549 human cancer cell line. Among them, N-(2,3-methylenedioxy-6-methoxy-phenanthr-9-y
基于极性菲的酪氨酸衍生物(PBT)被设计,合成和评估为潜在的抗肿瘤药物。这些化合物具有核心菲结构,并且可以以优异的收率有效地合成。评估了新合成的PBT对A549人癌细胞系的细胞毒活性。其中,N-(2,3-亚甲二氧基-6-甲氧基-菲-9-基甲基)-L-2-哌啶甲醇(34)和N-(2,3-亚甲二氧基-6-甲氧基-菲-9-基甲基)-5-氨基戊醇(28)的效能最高,IC50值分别为0.16和0.27 microM,与目前使用的抗肿瘤药相当。还探索了结构-活性关系(SAR)研究,以促进这种新化合物类别的进一步发展。
