| 内容記述 | The physicochemical processes underlying the radiation sensitization of DNA by the K-shell pho-toabsorption of nitrogen and oxygen atoms are unclear. Accordingly, we evaluated electron para-magnetic resonance spectra of thin films of pyrimidine bases. By altering the substituents of the pyrimidine ring, we found a substituent effect on the yield of unpaired electrons induced by photo-absorption. The yield of the unpaired electrons of the DNA-base containing amino groups increased by the donation of electrons, and the yield of halogenated DNA-bases decreased by the withdrawal of electrons. These different physicochemical processes might affect DNA bases, leading to differ- ences in DNA modification. |
