a Cell survival assay in A549-DDP cells treated with NO.0449-0145 for 48 h. b Morphological analysis of different treated A549-DDP cells. c Representative Hoechst/PI fluorescence images of A549-DDP cells with different treatment. d Western blotting analysis of γ-H2AX in different treated A549-DDP cells. e Representative image of Immunofluorescence staining for γ-H2AX foci. f Drug sensitivity assay of A549-DDP cells following co-treatment with cisplatin and NO.0449-0145 or vehicle. The data are presented as the mean ± SD values, and the error bars represent data from triplicate biological experiments. *p < 0.05; **p < 0.01; ***p < 0.001.
