Discovery of Isoplumbagin as a Novel NQO1 Substrate and Anti-Cancer Quinone
Isoplumbagin (5-hydroxy-3-methyl-1,4-naphthoquinone), a naturally occurring quinone from <i>Lawsonia inermis</i> and <i>Plumbago europaea</i>, has been reported to have anti-inflammatory and antimicrobial activity. Inflammation has long been implicated in cancer progression....
