A method was developed for the synthesis of dihydroberberine nitroaryl derivatives on the basis of dihydroberberine reactions with aromatic electrophiles (picryl chloride, 4-chloro-7-nitrobenzofurazan, 4-chloro-5,7-dinitrobenzofurazan, and 7-chloro-4,6-dinitro-benzofuroxan). The obtained 13-substituted dihydroberberine derivatives represent structures with significant intramolecular charge transfer and, according to the results of molecular docking analysis, can effectively bind with Gquadruplexes of telomeric DNA fragments.
