  Acyl migration in the production of thymine. Propenal from 3'-O-benzoyl-5'-deoxy-4'-(hydroperoxy)thymidine: a reinterpretation of a putative model for bleomycin-mediated DNA degradation

  摘要：

  Studies of Saito et al. (Saito, I.; Morii, T.; Matsuura, T. J. Org. Chem. 1987, 52, 1008) analyzing the decomposition of 3'-O-benzoyl-5'-deoxy-4'-hydroperoxythymidine (7) claimed to model the decomposition of the putative 4'-hydroperoxynucleotide intermediate in the bleomycin (BLM) mediated production of base propenal, 3'-phosphoglycolate, and 5'-phosphate termini from double-stranded DNA. A number of puzzling observations reported in this paper prompted a reinvestigation of this model system in detail. [4'-(HO2)-O-18]-7 and its 4' epimer 8 were prepared and their fate in aqueous solution as a function of pH was examined. Compound 7 decomposed in aqueous solution to produce thymine propenal accompanied by stoichiometric formation of benzoate containing 1 atom of O-18. In addition, thymine accompanied by stoichiometric amounts of malondialdehyde and [O-18]benzoate was also observed. Acetate containing 1 atom of O-18 accompanied production of both thymine and thymine propenal. The ratio of thymine propenal to thymine varied as a function of pH and temperature. Production of [O-18]benzoate and a detailed kinetic analysis of the decomposition of 7 unequivocally demonstrated that conversion of 7 to thymine propenal required the intermediacy of a 4'-perbenzoate ester. This perester produced by migration of the 3'-benzoyl blocking group of 7 to the terminal oxygen of its 4'-hydroperoxy moiety would then greatly facilitate heterolytic cleavage of the oxygen-oxygen bond. For stereochemical reasons a similar intramolecular benzoyl migration cannot occur with 8, explaining its lack of reactivity. These results call into question the relevance of the model proposed by Saito et al. to understanding the base propenal pathway in the BLM-catalyzed degradation of DNA. In addition, preparation of a second model of a putative intermediate in the base propenal pathway, [1-[[2-(acetyloxy)acetyl]oxy]-3-oxopropyl]thymine (12), is reported. The detailed kinetics of its decomposition as well as identification of the products accompanying its decomposition are reported. The relevance of these two model systems to the mechanism of degradation of DNA by BLM is discussed.

  Well-defined substrates for the study of oxidative processes are important for the elucidation of the role of DNA damage in the etiology of diseases such as cancer. We have synthesized 3'-modified oligodeoxyribonucleotides (ODNs) using 5' -> 3' 'reverse' DNA synthesis for the study of 2-deoxyribose oxidative damage to DNA. The modified monomers designed for these studies all share a common feature, they lack the naturally occurring 3'-hydroxyl group found in 2-deoxyribonucleosides. Modified H-phosphonates containing 3'-phenyl selenides as well as saturated and unsaturated sugars were obtained and incorporated in ODNs. These ODNs were used to investigate the fate of C3'-dideoxyribonucleotide radicals in DNA. (c) 2012 Elsevier Ltd. All rights reserved.
