Recognition of single stranded and double stranded DNA/RNA sequences in aqueous medium by small bis-aromatic derivatives.

The aim of this review is to summarize the most comprehensive results in the field of bis-aromatic compounds targeting DNA and RNA, whereby both aromatic units of small molecule bind to the polynucleotide by the aromatic stacking interactions. The most recent results about structure - DNA/RNA binding affinity, selectivity and biological implications are discussed for bis-intercalators, sterically restricted macrocyclic and threading bis-aromatics and intercalator - nucleobase conjugates.
