A novel phenanthrene imine was synthesized from 9,10-phenanthrenequinone, 1,4-diazabicyclo octane （Dabco）, 2,6-dimethylaniline, 2,6-diisopropylaniline and TIC14 via standard Schlenk and vacuum-line or glovebox techn...A novel phenanthrene imine was synthesized from 9,10-phenanthrenequinone, 1,4-diazabicyclo octane （Dabco）, 2,6-dimethylaniline, 2,6-diisopropylaniline and TIC14 via standard Schlenk and vacuum-line or glovebox techniques. 3-（4,5-Dimethylthiazolyl-2）-2,5-diphenyltetrazolium bromide（MTT） assay and flow cytometry（FCM） were used to detect the activities of the compound to kill tumor cells and the mechanisms of action were investigated in the study. The results show that the compound is active in killing tumor cells. Mechanistic investigations found that the compound could induce apoptosis of tumor cells.展开更多
