We report the results of a computational study of the possible metabolites
of 4-aminoazobenzene (AAB) and its monomethoxy derivatives using density fu
nctional theory (DFT) and the semiempirical AMI method. These calculations
identify several factors that may influence the radically different carcino
genic activities of 2-methoxy-and 3-methoxy-AAB. (C) 2001 Elsevier Science
