title: NO induced novel DNA lesions: formation mechanism.
abstract: 2'-Deoxyguanosine was treated with NO/O2 mixture at pH 7.0-7.8, and as well as the known major products such as 2'-deoxyxanthosine and 2'-deoxyoxanosine, some unidentified products were detected by RP-HPLC. In the present study, one of them has been characterized as a novel lesion, N2-nitro-2'-deoxyguanosine by spectrometric and chromatographic analysis. The mechanism for the production is also discussed.
