Stable nano-formulation of Plumbagin nanoparticles from Plumbago zeylanica root extract
was explored as a potential natural drug against prostate cancer. Size and morphology analysis by
DLS, SEM and AFM revealed the average size of nanoparticles prepared was 100±50nm. In vitro cytotoxicity
showed concentration and time dependent toxicity on prostate cancer cells. However, plumbagin
crude extract found to be highly toxic to normal cells when compared to plumbagin nanoformulation,
thus confirming nano plumbagin cytocompatibility with normal cells and dose dependent toxicity to prostate cells.
In vitro hemolysis assay confirmed the blood biocompatibility of the plumbagin nanoparticles. In wound healing assay,
plumbagin nanoparticles provided clues that it might play an important role in the anti-migration of prostate cancer cells.
DNA fragmentation revealed that partial apoptosis induction by plumbagin nanoparticles could be expected as a potent
anti-cancer effect towards prostate cancer.
