site inhibitors with potent antiproliferative activities. Among these compounds, 3,5-dimethoxyphenylpyridines 8j bearing a 4-methoxybenzyl aniline side-chain displayed the best antiproliferative activities against glioma (U87MG and U251). In addition, the trimethoxyphenylpyridine 8o bearing a 4-methyl-N-methyl aniline side-chain showed the best antiproliferative activities against colon carcinoma and
设计并合成了 19 种 TH03 类似物作为具有强效抗增殖活性的微管蛋白秋水仙碱结合位点抑制剂。在这些化合物中,带有 4-甲氧基苄基苯胺侧链的3,5-二甲氧基苯基吡啶8j对胶质瘤(U87MG 和 U251)表现出最好的抗增殖活性。此外,带有4-甲基-N-甲基苯胺侧链的三甲氧基苯基吡啶8o对结肠癌和肺癌的抗增殖活性最好,IC 50值最低(0.09 µM < IC 50 < 0.86 µM)。与 CA-4 相比,化合物8j和8o对正常细胞的细胞毒性较低,但对 RKO(IC 50 = 0.15 µM 和 0.09 µM)、NCI-H1299(IC 50 = 0.73 µM 和 0.14 µM)和 A549 细胞(IC 50 = 0.86 µM 和 0.37 )的抗增殖活性较高µM 分别)。进一步研究表明,8o 比秋水仙碱 (IC 50 = 8.6 ± 0.2 µM)显示出更高的微管蛋白聚合抑制活性
