Novel imidazo[4,5-b]pyridine and triaza-benzo[c]fluorene derivatives: Synthesis, antiproliferative activity and DNA binding studies
In the present paper, we have described the synthesis and biological activity of the novel derivatives of imidazo[4, 5-b]pyridines and triaza-benzo[c]fluorenes (7-21, 24-26, 28-29). A preponderance of these compounds exerted strong cytostatic effects on the panel of seven human tumour cell lines in a dose-dependent manner. In particular, imidazo[4, 5-b]pyridines and triaza-benzo[c]fluorenes including 2-imidazolinyl derivatives showed the most potent antitumour activity. Similarly, triaza-benzo[c]fluorenes 18 and 20 induced strong growth inhibition of tested tumour cell lines, and showed low cytotoxicity in normal human fibroblasts. DNA interaction studies of these compounds demonstrated that N-methylated 16 and 2-imidazolinyl 28 triaza-benzo[c]fluorenes bind to DNA in an intercalative mode.
