The product ion formation characteristics of four diastereomeric deoxyadenosine adducts formed by the reaction of the syn and anti diastereomers of trans-3,4-dihydroxy-5,5a-epoxy-3,4,5,5a-tetrahydrobenzo[ghi]fluoranthene are studied by matrix-assisted laser desorption ionization and postsource decay (PSD) to determine fragmentation pathways that may permit(More)
This paper reports structural characterization of the adducts and tetraols formed from syn-benzo[ghi]fluoranthene-3,4-dihydrodiol-5,5a-epoxide (syn-B[ghi]FDE, 3) and comparative DNA-binding and mutagenicity studies involving 3, anti-B[ghi]FDE (2), and anti-benzo[c]phenanthrene-11,12-dihydrodiol-13,14-epoxide (anti-BcPDE, 5). The structures of nine DNA(More)
The product ion formation characteristics of the four diastereomeric tetrahydroxy benzo[ghi]fluoranthene compounds formed by hydrolysis of the syn and anti diastereomers of trans-3,4-dihydroxy-5,5a-epoxy-3,4,5,5a-tetrahydrobenzo[ghi]fluoranthene are studied using matrix-assisted laser desorption/ionization and post-source decay (PSD) to determine a(More)
A total of seven DNA adducts and two racemic tetraols derived from anti-benzo[ghi]fluoranthene-3,4-dihydrodiol-5,5a-epoxide (anti-B[ghi]FDE, 2) were characterized by analyses of UV, (1)H NMR, CD, and MALDI mass spectra. The structure of 2 is the first example of a diolepoxide in which a fully fused cyclopentane ring is covalently linked to the saturated(More)
