Pipoxolan (cas 18174-58-8) has been reported to have antitumor activity. However, the effects of pipoxolan on lung cancer cell metastasis remains unclear. This study examined the anti-metastatic effects of pipoxolan on lung adenocarcinoma cancer cells (i.e. CL1–5, CL1–0, and A549) and its underlying molecular mechanisms. Firstly, CL1–5 cell migration was markedly suppressed by pipoxolan when examined by wound scratch assay. Furthermore, transwell and matrigel invasion assays revealed that pipoxolan inhibited lung cancer cells (i.e. CL1–5, CL1–0, and A549) migration/invasion, and showed more sensitive to CL1–5 cell. Therefore, the anti-metastatic effects from pipoxolan have been focused on CL1–5 lung cancer cells. Secondly, these observations have been associated with the reduction in the activities and expressions of matrix metalloproteinase (MMP)-2 and -9 in CL1–5 lung cancer cells. Lastly, pipoxolan administration significantly inhibited phosphorylation c-Jun N-terminal kinase (p-JNK), and p38 MAP Kinase (MAPK) of CL1–5 cells. Based on these results, our results showed that management CL1–5 cells with pipoxolan down-regulated phosphorylation JNK and p38, and then, MMP-2 and -9. These results suggest that pipoxolan might have a new therapeutic potential for anti-metastatic effects in lung cancer cells.
