hypoxic conditions than Tirapazamine, 3‐aminobenzo[1, 2‐e]1, 2, 4‐triazine N1, N4‐dioxide. Derivative 11, 6‐methyl‐5‐[2‐(5‐nitrofuryl)ethenyl)‐1, 2, 4‐triazine N4‐oxide, was the most cytotoxic compound, but it was non‐selective. Some derivatives were studied as DNA‐binding agents in oxic conditions showing poor affinity for this biomolecule. This result showed that the cytotoxic activity in oxia is DNA
合成了新的 5-(2-芳基乙烯基)-1, 2, 4-三嗪 N-氧化物和 N, N'-二氧化物衍生物,以获得作为选择性缺氧细胞细胞毒素的化合物。当 5-甲基杂环与相应的亚胺鎓亲电试剂反应时,得到所需产物。测试了新化合物在含氧和缺氧条件下的细胞毒性。其中一些被证明在缺氧条件下的活性低于 Tirapazamine, 3-aminobenzo [1, 2-e] 1, 2, 4-triazine N1, N4-dioxide。衍生物 11, 6 - 甲基 - 5- [2- (5 - nitrofuryl) 乙烯基) -1, 2, 4 - 三嗪 N4 - 氧化物是最具细胞毒性的化合物,但它是非选择性的。一些衍生物被研究作为 DNA 结合剂在有氧条件下显示对这种生物分子的亲和力较差。该结果表明,氧中的细胞毒活性不依赖于 DNA 损伤。
