1,4-Difluorobenzo[c]phenanthrene (1,4-DFBcPh) and its putative metabolites, the dihydrodiol and diol epoxides, have been synthesized and structurally characterized, and the extent of DNA binding by the metabolites has been assessed. 1,4-DFBcPh and 1,4-difluoro-10-methoxybenzo[c]phenanthrene were prepared by photochemical cyclization of appropriate(More)
The central adenine residue (A) of codon 61 in the human N-ras proto-oncogene, 5'-CGGACAAGAAG-3', has been modified with each enantiomer of the series 1 (DE-1, syn) and series 2 (DE-2, anti) benzo[a]pyrene diol epoxide through total chemical synthesis. The resulting DNA adducts correspond to a trans ring-opening of the oxiranes at the C-10 position of the(More)
