indicated that the 2′R analogues were generally more cytotoxic than the 2′S analogues. Additionally, several analogues exhibited selective inhibition against various cancer cell lines: compounds 32a and 32b selectively inhibited MCF-7 cells, while 33b and 35b were more sensitive toward Lu-1 and HepG-2, respectively. Notably, some of the synthetic analogues possess cytotoxic activities with IC50 values less
通过酰胺偶联反应,从相应的聚酮链和氨基酸制备了一系列的苯甲酰胺E类似物。在2-乙基己酸钠的存在下,在微波辐射下成功地实现了α-氨基内酰胺与聚酮化合物内酯环的开环。针对癌细胞系的面板的细胞毒性活性的评估(KB,人肝癌HepG-2,路-1,MCF-7,HL-60和Hela)指出,2' - [R类似物一般比2多的细胞毒性“ š类似物。另外,几种类似物表现出对多种癌细胞系的选择性抑制:化合物32a和32b选择性抑制MCF-7细胞,而33b和35b分别对Lu-1和HepG-2敏感。值得注意的是,某些合成类似物具有细胞毒活性,IC 50值小于1 µM。
