Objective To investigate the effect of centaureidin on the proliferation and apopto-sis of A549 cells and its mechanism of action.Methods The proliferation of A549 cells was meas-ured by MTT assay,the apoptosis by Hochest staining,the apoptosis rate and cell cycle by flow cytometry,and the expression of NF-κB P65 by Western blot.Results Centaureidin treatment suppressed proliferation,induced apoptosis and up-regulated NF-κB P65 expression in A549 cells in a dose-dependent manner.The median inhibitory concentration (IC50 )was 0.67 μmol·L-1 .G1 phase arrest was found in A549 cells treated with centaureidin at a concentration of 0.15 or 0.30 μmol·L-1 .Conclusion Centaureidin can induce apoptosis in A549 cells via activating NF-κB signal pathway.
