concentration levels. Detailed studies on the most active compounds 11–13 show these compounds are capable to inhibit the growth of cancer cells. Finally, with the aim to correlate the antiproliferative activity with an intracellular target(s), the effect on relaxation activity of DNA topoisomerase-II is assayed. The relevance of interaction of most active compounds with topoisomerase-II is demonstrated which is
为了在结构上关联用于乳腺癌的抗癌药物
他莫昔芬,设计并合成了一系列化合物作为潜在的候选药物。McMurry偶联反应被用作制备这些类似物的关键合成步骤,E / Z异构体的比例是根据NMR和HPLC实验确定的。发现这些新化合物在微摩尔范围内具有60种人类肿瘤
细胞系的1剂量和5剂量浓度
水平的细胞毒性。上最活跃的化合物的详细研究11 - 13表明这些化合物能够抑制癌细胞的生长。最后,以使抗增殖活性与细胞内靶标相关为目的,测定了DNA拓扑异构酶-II对松弛活性的影响。证明了大多数活性化合物与拓扑异构酶-II相互作用的相关性,这也得到了对接研究的支持。
