plumbagin

Plumbagin (Plumbaein) is a yellow dye, formally derived from naphthoquinone. It is named after the plant genus Plumbago, from which it was originally isolated. It is also commonly found in the carnivorous plant genera Drosera and Nepenthes. It is also a component of the black walnut drupe.

2-(Cyclohexylmethyl)-Plumbagin, a naphthoquinone derivative, exhibits selective cytotoxicity towards PANC-1 human pancreatic cancer cells under nutrient-deprived conditions—a situation akin to the pancreatic cancer tumor microenvironment—over those in nutrient-rich settings, with PC50 values of 0.11 and 47.2 µM, respectively. At a 1 µM concentration, it triggers apoptosis in PANC-1 cells. Furthermore, this compound specifically inhibits the phosphorylation of Akt and mammalian target of rapamycin (mTOR) in PANC-1 cells under nutrient scarcity. In a MiaPaCa-2 pancreatic cancer mouse xenograft model, it significantly reduces tumor volume and weight when administered at 50 and 250 µg/animal dosages five times weekly.

ISOPLUMBAGIN, a naturally occurring quinone compound derived from Lawsonia inermis and Plumbago europaea, has been reported to possess anti-inflammatory and antimicrobial activities.
