title: [Specificity of the interaction of carcinogenic and cytostatic agents with the elements of the genome at different levels of its organization].
abstract: The analysis of the literature permits drawing a conclusion that according to DNA binding site-specificity carcinogens and antitumour drugs can be divided into GC- and AT-binding compounds. When interacting with eucaryotic DNA such specificity leads to an increased binding of carcinogens and antitumour drugs to the repeat-rich DNA (satellite DNA, alpha-DNA, flanking regions of genes). It is supposed that specificity of the binding of chemical compounds on higher levels of genome organization (active and inactive chromatin, nuclear matrix-bound DNA) is also defined by the affinity of compounds to GC- or AT-rich repeats.
