Seven benzylamino derivatives of podophyllotoxin 8a–8g were synthesized and their chemical structures were confirmed by IR, 1H‐NMR, 13C‐NMR and ESI‐MS spectral analyses. Their abilities to inhibit the growth of cancer cells A549, HCT‐116 and HepG2, were investigated by MTT assay. Compound 8b possessed the highest cytotoxicity on cancer cell lines with average IC50 values of 3.8 µM. All we synthetic
合成了 7 种鬼臼毒素 8a-8g 的苄氨基衍生物,并通过 IR、1H-NMR、13C-NMR 和 ESI-MS 光谱分析证实了它们的化学结构。通过 MTT 测定研究了它们抑制癌细胞 A549、HCT-116 和 HepG2 生长的能力。化合物 8b 对癌细胞系具有最高的细胞毒性,平均 IC50 值为 3.8 µM。我们合成的所有化合物在微摩尔范围内对三种癌细胞系都具有细胞毒性,这表明具有苄氨基结构修饰的鬼臼毒素衍生物具有有效的抗肿瘤活性。
