The product ion formation characteristics of the protonated molecule ions generated from 10 different deoxynucleoside adducts of benzo[ghi]fluoranthene (B[ghi]F) have been studied using electrospray ionization (ESI) and quadrupole ion trap mass spectrometry to gain a better understanding of the fragmentation mechanisms that govern structure-specific fragmentation. The reaction of the syn- and anti-diastereomers...
Matrix-assisted laser desorption/ionization (MALDI) and time-of-flight mass spectrometry (TOFMS) are tested for the determination of arylamide adducts of deoxyguanosine. Fifteen matrices were tested for the sensitive determination of N-(guanosin-8-yl)-2-acetylaminofluorene, (dG-C8-AAF), a compound whose structure is representative of carcinogen-DNA adducts formed by nitroaromatic and arylamine carcinogens...
