Computer Modelling Studies of the Covalent Interactions between DNA and the Enantiomers of anti-7,8-Diol,9,10-Epoxy-Benzo[a]pyrene

Abstract
The molecular structures of adducts between the + and—enantiomers of 7,8-diol 9,10-epoxy benzo[aJpyrene and a double-stranded model for DNA, have been examined by empirical energy calculations. Low-energy structures were only obtained for A form, and not B form DNA. Both + and—adducts are of approximately equal energy. Some structural differences in the orientation of the BP chromophore in the two adducts were found.
