Abstract To investigate the effects and mechanisms of 4-(1H-indol-1-yl)-4-oxobutanoic acid spliced podophyllotoxin derivatives (3a–3l) on tumor cells. The MTT method was adopted to evaluate (3a–3l) antitumor activity in vitro against A549 cells, A549/DDP cells, MCF-7 cells. The results showed that compound 3l had the most prominent inhibitory effect and high selectivity with IC50 18.53 ± 1.51 µM against
摘要 研究4-(1 H -indol-1-yl)-4-oxobutanoic acid spliced podophyllotoxin derivatives ( 3a – 3l ) 对肿瘤细胞的作用和机制。采用MTT法评价( 3a – 3l )体外对A549细胞、A549/DDP细胞、MCF-7细胞的抗肿瘤活性。结果表明,化合物3l对A549/DDP细胞具有最显着的抑制作用和高选择性,IC 50 为18.53 ± 1.51 µM。同时,化合物3l对A549/DDP细胞核态、细胞周期和凋亡的影响表明,化合物3l通过延迟G2 A549/DDP 细胞周期的 /M 期。此外,化合物3l的分子对接也表明它可以 在微管蛋白的秋水仙碱位点与ARG-158( d = 2.6, 2.7 Å)和HIS-406(d = 2.5 Å)形成良好的氢键。化合物3l可为开发新的多重耐药抗肿瘤药物提供先导化合物。
