Cat.No. 4761 - Plumbagin | C11H8O3 | CAS No. 481-42-5
Description: Induces G2/M cell cycle arrest; anticancer
Chemical Name: 5-Hydroxy-2-methyl-1,4-naphthalenedione
Purity: ≥98% (HPLC)

Biological Activity

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.

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
