A series of 2-(benzylthio)-5-aryloxadiazole derivatives have been designed and synthesized, and their biological activities are also evaluated for EGFR inhibitory activity. Fourteen compounds among the twenty compounds are reported for the first time. Their chemical structures are characterized by 1H NMR, MS, and elemental analysis. Anti-proliferative and EGFR inhibition assay results have demonstrated
已经设计和合成了一系列2-(苄硫基)-5-芳基恶二唑衍生物,并且还评估了它们的生物活性对EGFR的抑制活性。首次报道了二十种化合物中的十四种化合物。它们的化学结构通过1 H NMR,MS和元素分析进行表征。抗增殖和EGFR抑制测定的结果已经证实,化合物3e中示出了最有效的生物活性(IC 50 = 1.09μM为MCF-7和IC 50 = 1.51μM为EGFR)。已执行对接仿真以定位化合物3e进入EGFR活性位点以确定可能的结合模型,估计结合自由能值为-10.7 kcal / mol。在肿瘤生长抑制中具有有效抑制活性的化合物3e可能是有前途的抗肿瘤主导化合物,值得进一步研究。
