Several new 1,2,5-oxadiazole N-oxide derivatives and some deoxygenated analogues were synthesized to be tested as potential selective hypoxic cell cytotoxins. Compounds prepared were designed in order to gain insight into the mechanism of action of this kind of cytotoxin. Compounds were tested in oxia and hypoxia and they proved to be non-selective. 3-Cyano-N(2)-oxide-4-phenyl-1,2,5-oxadiazole showed
合成了几种新的1,2,5-恶二唑N-氧化物衍生物和一些脱氧类似物,作为潜在的选择性低氧细胞毒素进行了测试。设计制备的化合物是为了深入了解这种细胞毒素的作用机理。在缺氧和缺氧状态下测试了化合物,事实证明它们是非选择性的。3-氰基-N(2)-氧化物-4-苯基-1,2,5-恶二唑显示出最佳的细胞毒性活性。这些衍生物观察到的细胞毒性可以用1,2,5-恶二唑取代基的电子特性来解释。对细胞毒性更高的衍生物进行了电化学和ESR研究。
