Nineteen new phenanthrene-based tylophorine analogues with various functional groups on the piperidine moiety were designed, synthesized, and evaluated for in vitro anticancer activity against four human tumor cell lines. Analogues 15 and 21 showed approximately 2-fold enhanced inhibitory activity as compared with our prior lead compound (PBT-1). Analogues 23 and 24 with S- and R-configured substituents
设计、合成了 19 种新的基于菲的 tylophorine 类似物,在哌啶部分具有各种官能团,并评估了其对四种人类肿瘤细胞系的体外抗癌活性。与我们之前的先导化合物 (PBT-1) 相比,类似物15和21显示出大约 2 倍增强的抑制活性。具有S-和R- 的类似物23和24分别在哌啶 3'-位配置的取代基表现出与 PBT-1 相当的细胞毒性。此外,研究新化合物对肺癌细胞中 Akt 蛋白和 NF-kB 信号通路影响的机制研究表明,这些化合物可能通过抑制 Akt 和 NF-kB 信号传导的激活来发挥对肿瘤细胞的抑制活性途径。
