Description

General description

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.

Application

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

Biochem/physiol Actions

Plumbagin exhibits various pharmacological activities including antimicrobial, anticancer, anti-atherosclerotic, antidiabetic, anti-inflammatory, hypolipidemic, and neuroprotective activities. It inhibits the signal transducer and activator of transcription 3 (STAT3) signaling and halts the proliferation of esophageal squamous cell carcinoma (ESCC). Plumbagin elicits protective antioxidative functionality in 4-nitroquinoline-N-oxide (NQNO) induced stress in lymphoma. Plumbagin in a nanoemulsion formulation has antiproliferative effect towards prostate cancer.

Exhibits cytotoxicity in rodent models of carcinogenesis and carcinoma; has antifungal, antiviral, and antibacterial action.
