abstract：:Plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone) is a small molecule with potent anticancer activity. Like other 1,4-naphthoquinones, it exhibits electrophilic reactivity towards biological nucleophiles. We demonstrate that plumbagin and structurally related 1,4-naphthoquinones with at least one unsubstituted quinoid...
