  Independent Generation and Reactivity of 2‘-Deoxy-5-methyleneuridin-5-yl, a Significant Reactive Intermediate Produced from Thymidine as a Result of Oxidative Stress

  摘要：

  2'-Deoxy-5-methyleneuridin-5-yl (1) is produced in a variety of DNA damage processes and is believed to result in the formation of lesions that are mutagenic and refractory to enzymatic repair. 2'-Deoxy-5-methyleneuridin-5-yl (1) was independently generated under anaerobic conditions via Norrish Type I photocleavage during Pyrex filtered photolysis of the benzyl ketone 7. The radical (1) exhibits behavior consistent with that of a resonance-stabilized radical. The KIE for hydrogen atom transfer from t-BuSH was found to be 7.3 +/- 1.7. Competition studies between radical recombination and hydrogen atom donors (2,5-dimethyltetrahydrofuran, k(Trap) = 46.1 +/- 15.4 M-1 s(-1); propan-2-ol, k(Trap) = 13.6 +/- 3.5 M-1 s(-1)) chosen to mimic the carbohydrate components of 2'-deoxyribonucleotides suggest that 2'-deoxy-5-methyleneuridin-5-yl (1) may be able to transfer damage from the nucleobase to the deoxyribose of an adjacent nucleotide in DNA under hypoxic conditions.
