of (3/5-aryl-1,2,4-oxadiazole-5/3-yl)(3,4,5-trimethoxyphenyl)methanone oxime derivatives were synthesized via a rapid and facile microwave-assisted synthesis method of building a 1,2,4-oxadiazole skeleton using mandelic acid as the starting material. Twenty-four target compounds were evaluated for their in vitro antiproliferative activities against three human cancer cell lines (SGC-7901, A549 and HT-1080)
通过快速,简便的微波辅助合成方法合成了一系列(3 / 5-芳基-1,2,4-恶二唑-5 / 3-基)(3,4,5-三甲氧基苯基)甲酮肟衍生物。以扁桃酸为起始原料的1,2,4-恶二唑骨架。评价了二十四个目标化合物对三种人类癌细胞系(SGC-7901,A549和HT-1080)的体外抗增殖活性。其中16b对不同的肿瘤细胞系,尤其是A549细胞系,具有最高的效力(IC 50= 87 nM)。结构-活性关系(SAR)研究表明,1,2,4-恶二唑环上C-5位的芳基取代基优于C-3位。与SMART衍生物相反,肟作为连接剂可以明显提高效价。此外,16b显着诱导细胞周期停滞在G2 / M期,并导致微管不稳定。分子对接研究在微管蛋白二聚体的秋水仙碱位点提供了16b的理论结合模式。我们的工作为新型微管蛋白聚合抑制剂的进一步结构指导设计奠定了基础。
