Chemical Name: 5-Hydroxy-2-methyl-1,4-naphthalenedione
Biological ActivityPlumbagin is an anticancer agent. Induces G2/M cell cycle arrest and apoptosis in A549 cells through JNK-dependent p53 Ser15 phosphorylation; inhibits A549 and MDA-MD-231 tumour xenograft growth in nude mice. Promotes autophagic cell death in MDA-MB-231 and MCF-7 cells and inhibits Akt/mTOR signaling. Induces intracellular ROS generation in a PI 5-kinase-dependent manner. Also inhibits p300-mediated acetylation of p53.
