Chemoselectivity in DNA: The thymidine lesion 5‐formyl‐2′‐deoxyuridine (1) induces the mutation of DNA. Its derivatization with the specific fluorogenic reagent 2‐amino‐4,5‐dimethoxythiophenol (2) gives 3, which shows strong fluorescence. This fast method for the detection of 1 requires no enzymatic digestion, HPLC separation, or MS analysis. ROS=reactive oxygen species.
DNA的化学选择性:胸腺嘧啶核苷5-甲酰基-2'-脱氧尿苷(1)诱导DNA突变。用特定的荧光试剂2-氨基-4,5-二甲氧基硫酚(2)衍生化得到3,显示出很强的荧光。这种检测1的快速方法不需要酶消化,HPLC分离或MS分析。ROS =活性氧。
