Synthesis and antiproliferative activity of some N-sulphonated-2-substituted benzimidazoles and imidazo[4,5-b]pyridines.
Some N-sulphonated-2-substituted benzimidazoles and imidazo[4,5-b]-pyridines were synthesized and tested in vitro for antiviral and antiproliferative activity. None of the compounds had antiviral properties. However, three of them inhibited the proliferation of leukaemia and lymphoma cell lines at micromolar concentrations. The maximum potency of antiproliferative activity is correlated with the presence of an ethylenic spacer between the two heterocycles.
