6-Disubstituted aryl 1-methyl-4-nitro-5-imidazolyl sulfones 4 and aryl 1-neopentyl-2-tert-butyl-4-nitro-5-imidazolyl sulfones 10 have been synthesized and tested as radiation sensitizers of hypoxic carcinoma cells. These sterically crowded imidazoles show decreased displacement reactivity with glutathione at C-5, a major metabolic reaction known to deplete effective plasma drug levels in traditional aryl imidazolyl
合成了2,6-二取代的芳基1-甲基-4-硝基-5-咪唑基砜4和芳基1-新戊基-2-叔丁基-4-硝基-5-咪唑基砜10并作为低氧辐射敏化剂进行了测试。癌细胞。这些空间拥挤的咪唑在C-5处显示出与谷胱甘肽的置换反应降低,这是一种主要的代谢反应,已知该反应会耗尽传统芳基咪唑基砜辐射敏化剂中的有效血浆药物水平。
