This study evaluated the selective effects of 2-isopropyl-3-butyl-8-(4-fluorophenylamino)-3H-imidazo[4,5-g]quinazoline (B-2), a member of a series of quinazolines, on the cell survival and growth of the non-small cell lung cancer (NSCLC) cell line A549 in vitro and in vivo. Cytotoxicity assay, hollow fiber assay and cell xenograft model experiment revealed that B-2 showed selective effects on A549 cell survival or growth in a dose-dependent manner. At a dose of 100mg/kg, B-2 showed stronger efficacy on tumor growth inhibition in nude mice than Iressa. Exposure of A549 cells to B-2 caused inhibition of EGFR-dependent ERK-MAPK activation. In addition, inhibition of cell cycle progression and induction of mitochondria-dependent apoptosis might contribute to present the multitarget pathway of non-small cell lung cancer treatment of B-2.
