Abstract

The covalent modification of 2′-deoxycytidine (dCyd) by genotoxic bifunctional electrophiles, to produce unsubstituted and substituted etheno-dCyd adducts was discussed. The presence of DNA-adducts increased the probability of errors during DNA replication. The decomposition of 13- hydroperoxyoctadecadienoic acid (13-HPODE) was analyzed by reverse-phase chromatography with an acetonitrile/water system. The results of analysis show that the decomposition of 13-HPODE in the presence of dCyd by Liquid chromatography/atmospheric pressure chemical ionization/mass spectrometry revealed the formation of the unsubstituted 3,N ⁴-etheno-dCyd adduct and two substituted etheno-dCyd adducts.
