e and 4β-cinnamido linked podophyllotoxin congeners have been synthesized. All the twenty nine compounds were evaluated for anticancer activity against five human cancer cell lines (A-549, A375, MCF-7, HT-29 and ACHN). Some of the synthesized compounds showed good anticancer activity that is comparable to etoposide. The IC50 of compounds 17a and 17f is 2.7 and 2.1 μM respectively against A-549 cancer
已经合成了一系列的4β-烷基
氨基
十二烷和4β-肉桂连接的
鬼臼毒素同源物。评估了全部29种化合物对五种人类癌
细胞系(A-549,A375,MCF-7,HT-29和ACHN)的抗癌活性。一些合成的化合物显示出与
依托泊苷相当的良好抗癌活性。化合物17a和17f的IC 50对A-549癌
细胞系的IC 50分别为2.7和2.1μM。流式细胞仪分析表明,这两种化合物将细胞周期阻滞在G2 / M期,导致caspase-3依赖性凋亡
细胞死亡。此外,Hoechst 33258染色和DNA片段分析还表明17a和17f 通过凋亡诱导
细胞死亡。
