Beschreibung
Plumbagin is a natural 1,4-naphthoquinone first isolated from plants of the genus Plumbago. It has diverse effects in cells and animals. Plumbagin causes the generation of reactive oxygen species and induces apoptosis in cancer cells. It activates signaling through Nrf2 and the antioxidant response element, inducing the expression of Nrf2 target genes, including NQO1 and heme oxygenase-1 in cultured neuronal cells. Plumbagin also inhibits NADPH oxidase 4 in a time- and dose-Chemische Eigenschaften
ORANGE CRYSTALLINE POWDER OR CRYSTALSVerwenden
Plumbagin from Plumbago indica has been used:- as a reactive oxygen species agent (ROS) to induce cytotoxicity in mouse embryonic fibroblasts
- as an oxidative stress inducer to generate superoxide anion in Saccharomyces cerevisiae
- as a reference standard in thin layer chromatography and in spectrophotometric analysis for quantification of plumbagin in Plumbago auriculate samples
Definition
ChEBI: A hydroxy-1,4-naphthoquinone that is 1,4-naphthoquinone in which the hydrogens at positions 2 and 5 are substituted by methyl and hydroxy groups, respectively.Allgemeine Beschreibung
Plumbagin is a bioactive naphthoquinone present majorly in Plumbago indica L. It is a quinoid and is also derived from the roots of Plumbago zeylanica?roots.l?uterung methode
It crystallises in yellow needles from aqueous EtOH. It is soluble in organic solvents, it is steam volatile and it sublimes on heating in a vacuum.
