Remarkable promation of the hydroxylation of thimine to give thimine glycol with almost complete depression of side reactions by 2,2,6,6-tetramethylpiperidine-1-oxyl (TMPO·) derivatives was observed in the γ-radiolyses of the N2- and N2O-saturated aqueous solutions. In the O2-saturated solution, TMPO· depressed the thymine conversion close to the level under N2 while promoted the formation of thymine glycol to some extent by decreasing side reactions.
在γ射线辐照下,N2和N2O饱和水溶液中观察到显著的胸腺嘧啶羟基化生成胸腺嘧啶二醇,同时几乎完全抑制了副反应,这一过程中2,2,6,6-四甲基哌啶-1-氧基(TMPO·)衍生物发挥了重要作用。在O2饱和溶液中,TMPO·虽抑制了胸腺嘧啶的转化至接近N2条件下的水平,但通过减少副反应在一定程度上促进了胸腺嘧啶二醇的生成。
