Aim. To study a series of new acridine derivatives containing two basic fragments able to bind to quadruplex DNA at C-4 and C-9 positions as potential telomerase inhibitors. Methods. TRAP assay was used to determine the activity of compounds in vitro. Results. A number of acridines inhibiting the enzyme at micromolar concentrations were found, with IC50 = 2.6 µM for the most active compound. Conclusions. The introduction of a highly basic N,N-dimethylaminoalkyl group at the C-9 position of the acridine core results in a strong increase of biological activity of compounds, and a 5-methyl substituent further enhances it.
