Structural Insights and Pharmaceutical Relevance of Plumbagin in Parasitic Disorders: A Comprehensive Review.

Recently, natural products have been became the center of attraction for the scientific society and exploration of their biologically abilities is proceeding continuously. In search for novel antiparasitic agents with an objective of protecting humans from parasitic infections, the present work was focused on naphthoquinones possessing antiparasitic activity. Among naphthoquinones, plumbagin is one of the secondary metabolites exhibiting diverse biological properties such as antibacterial, antimalarial, antiinflammatory, insecticidal and antiparasitic. Plumbagin is reported to have antischistosomiasis, anti-haemonchosis, anti-fascioliasis, antiotoacariasis, anti-leishmaniasis, antimalaria, antiallergic and anthelmintic activities. Besides, various methods of extraction of plumbagin from different methods, their effectiveness against different parasites, and the structure-activity relationship reported by different researchers. This work highlight on recent advancements in the phytochemistry of plumbagin, studies associated with various biological activities. The structure-activity relationship studies have also been summarized. To conclude, present review could be beneficial for the scientific community to get better insight into medicinal research of plumbagin and may provide a new horizon for the rational design of plumbagin based compounds.
