چکیده انگلیسی
Four novel 4-(1H-imidazo[4,5-f]-1,10-phenanthrolin-2-yl)phenol derivatives 1-4 have been synthesized, and their G-quadruplex DNA-binding interactions, telomerase inhibition, antiproliferative activity, cell cycle arrest, and apoptotic induction were studied. All compounds show the preferential h-telo, c-myc, and c-kit2 G-quadruplex binding affinity and the G-quadruplex versus duplex selectivity. In the case of the same G-quadruplex target, the compound 1 exhibits better stabilization effect (ÎTm) than the other three compounds and also gives 80.2% inhibition of telomerase activity at 7.5 μM. All compounds can promote selectively the formation of parallel G-quadruplex structure of both c-myc and c-kit2 without addition of any cations. Four compounds display the cytotoxicity activities against HeLa and HepG2 cells by MTT assay with IC50 values of about 10â6 and 10â5 M, respectively, and cause a substantial decrease in the G2/M-phase cell population and a significant increase in the number of apoptotic cells.
