Next, we performed MTT assay and demonstrate that TBrC and T at concentrations of 5-100 μg/mL dose-dependently suppressed the growth of human non-small cell lung cancer (NSCLC) A549 and H460 cell lines (Figure 5A, B) without affecting cell viability of the normal human embryonic lung fibroblast MRC-5 cells (Figure 5C) after 48 h treatment of these cell lines with the same concentrations of TBrC and T, although Bay11-7082 (Bay/0.62 μg/mL, a specific inhibitor of NF-κB) exhibited toxicity to the normal MRC-5 cells by suppressing the cell growth (Figure 5A, C). Here, NFKB1 is linked to non-small cell lung carcinoma.
