1-[[(Diethylamino)ethyl]amino]- and 1,4-, 1,5-, and 1,8-bis[[(diethylamino)ethyl]amino]anthraquinones are shown to intercalate into DNA. Computer graphics modelling of their intercalation into the self-complementary deoxydinucleoside d(CpG) showed differences in binding properties. While the 1-substituted compound can bind from either groove, the 1,8-disubstituted compound binds with both substituents in the major groove. In the low-energy state of the complex with the 1,5-disubstituted compound, this ligand "straddles" the site with a substituent in each groove--to do this, the compound must bind to a non-base-paired region, so inducing base pairing. The 1,4-compound binds from the major groove; "straddling" is also possible if full minimization of deoxydinucleoside geometry is performed. The differences in binding mode and interaction energies are reflected in the affinities of interaction (1,5- greater than 1,4- much greater than 1,8- greater than 1-); also the antiproliferative effects in vitro are in general agreement with this ranking.
