A series of 1,3,4-oxadiazole derivatives containing 1,4-benzodioxan moiety (7a–7q) have been designed, synthesized and evaluated for their antitumor activity. Most of the synthesized compounds were proved to have potent antitumor activity and low toxicity. Among them, compound 7a showed the most potent biological activity against Human Umbilical Vein Endothelial cells, which was comparable to the positive
已设计,合成并评估了一系列含有1,4-苯并二恶烷部分(7a – 7q)的1,3,4-恶二唑衍生物的抗肿瘤活性。已证明大多数合成的化合物具有有效的抗肿瘤活性和低毒性。其中,化合物7a对人脐静脉内皮细胞表现出最强的生物学活性,与阳性对照相当。凋亡和流式细胞仪(FCM)的结果表明,化合物7a通过抑制MetAP2途径诱导细胞凋亡。进行分子对接以将化合物7a定位于MetAP2结合位点,以探索潜在的靶标。
