A series of [1,2,4]triazolo[4,3-b][1,2,4,5]tetrazine derivatives have been synthesized and their structures were confirmed by single-crystal X-ray diffraction. Compared to some reported structures of 1,6-dihydro-1,2,4,5-tetrazine, these compounds can't be considered as having homoaromaticity. Their antiproliferative activities were evaluated against MCF-7, Bewo and HL-60 cells in vitro. Two compounds
合成了一系列[1,2,4]三唑并[4,3-b] [1,2,4,5]四嗪衍生物,并通过单晶X射线衍射证实了其结构。与某些已报道的1,6-二氢-1,2,4,5-四嗪结构相比,这些化合物不能被认为具有同芳香性。在体外评估了它们对MCF-7,Bewo和HL-60细胞的抗增殖活性。两种化合物对MCF-7,Bewo和HL-60细胞均非常有效,IC50值为0.63-13.12μM。在51 [1,2,4]三唑[4,3-b]上进行了比较分子场分析(CoMFA)和比较分子相似性指标分析(CoMSIA)的三维定量构效关系(3D-QSAR)研究对MCF-7细胞具有抗增殖活性的] [1,2,4,5]四嗪衍生物。生成具有良好预测能力的模型,其中针对CoMFA和CoMSIA的交叉验证的q(2)值分别为0.716和0.723。常规r(2)值分别为0.985和0.976。结果提供了指导新的和更有效的四嗪衍生物的设计和合成的工具。
