Gene or Protein evidence NADPH: Quinone oxidoreductase 1 (NQO1) mediated anti-cancer effects of plumbagin in endocrine resistant MCF7 breast cancer cells. In conclusion, plumbagin inhibits the invasion of HER2-overexpressing breast cancer cells through the inhibition of IKKalpha-mediated NF-kB activation and downregulation of NF-κB-regulated MMP-9 expression. We also found that plumbagin inhibited survival signaling through the phosphatidylinositol 3-kinase/AKT signaling pathway by blocking the activation of AKT and downstream targets, including the mammalian target of rapamycin, forkhead transcription factors, and glycogen synthase kinase 3beta.
Target pathways Phosphatidylinositol 3-kinase/AKT signaling pathway
IC50 1.28 μM against MCF-7 130.8 μM against MDA-MB-231
Potency A plant metabolite, plumbagin, has potent anticancer activity via reactive oxygen species (ROS) generation. EC50 = >25 microM
Cell line/ mice model MCF-7, MDA-MB-231, HeLa, A549
Additional information  These results imply that plumbagin inhibits ERK activation in breast cancer cells, which plays a role in the sensitization of cells to paclitaxel-induced cell death.
