| Radiation-Induced Degradation of Purine and Pyrimidine 2'-Deoxyribonucleosides in Aqueous KBr Solutions  | | | | Abstract
| Steady-state y-radiolysis of 5 x 10 -4 M pyrimidine and purine 2'-deoxyribonucleosides in aqueous solutions saturated with N2, N2O and O2, respectively, have been carried out in the presence of 0.1 M KBr. The main final degradation products have been isolated and characterised by various spectroscopic measurements including !H and 13 C NMR, UV, C.D. and mass spectrometry. The radiation-induced decomposition of thymidine is mostly accounted for by an ionic mechanism involving Br2, the decay product of Br2 --, as the reactive oxidising specie. On the other hand the degradation of the purine ring of 2'-deoxy-adenosine and 2'-deoxyguanosine may be accounted for by the action of Br2 --or Br3-2_ . | | | |
