in the five cell lines tested. Therefore, compounds 2b and 8b were evaluated by flow cytometric analysis for their effects on cell cycle distribution and apoptosis in MCF-7 cells. 2b was the most active, with an apoptogenic effect similar to camptothecin, which was used as a positive control. Both of them provoked cell cycle arrest leading to the accumulation of cells in either G2/M and S phase. These
这里描述的研究涉及一系列三十种新的对称取代的亚氨基硫代氨基甲酸酯和亚氨基硒代氨基甲酸酯衍生物的合成及其在体外对五种人类肿瘤细胞系的抗肿瘤活性的评估:乳腺腺癌(MCF-7),结肠癌(HT- 29),淋巴细胞白血病(K-562),肝癌(Hep-G2),前列腺癌(PC-3)和一种非恶性乳腺衍生细胞系(MCF-10A)。在至少一种细胞系中,十八种化合物的GI 50值低于10μM。事实证明,两种癌细胞(MCF-7和HT-29)对5种化合物(1b,2b,3b,4b和5b)最敏感),其生长抑制在纳摩尔范围内,化合物1b,3b,7b,8b和9b的值小于1μM。此外,所有上述化合物均显示出较低的GI 50比一些标准的化学治疗药物的参考值高。结果还表明,在硒位置的脂族链的性质(甲基比苄基更好)和杂原子的性质(Se比S更好)对化合物的抗增殖活性有显着影响。这些发现加强了我们先前关于硒甲基作为此类化合物生物活性支
