Medicinal Plants and Neuroprotection

Vanillic acid is a phenolic compound, found in various dietary sources and medicinal plants. Apart from its extraction from these biological sources, it is also synthesized chemically. It is used as flavouring agent in various food products. It possesses anticancer, antiobesity, antidiabetic, antibacterial, anti-inflammatory, and antioxidant effects. Despite possessing good therapeutic potential and safety profile, it has not been well explored as nutraceutical or, therapeutic moiety. Literature search was conducted to systematically review the various mechanistic pathways through which vanillic acid showed multiple therapeutic effects. Along with these pathways, other applications of vanillic acid and its derivatives are highlighted. Some of the patents that have been filed hitherto, for the production and uses of vanillic acid are also entailed in the manuscript. Vanillic acid exerts diverse bioactivity against cancer, diabetes, obesity, neurodegenerative, cardiovascular, and hepatic diseases by inhibition of the associated molecular pathways. Its derivatives also possess the therapeutic potential to treat autoimmune diseases as well as fungal and bacterial infections. Owing to these benefits, vanillic acid has great potential to be used as a nutraceutical and provides scope for therapeutic uses beyond its traditional use as a flavouring agent. However, its oral bioavailability is limited due to its rapid elimination (metabolism) from the plasma. This, in turn, impedes its successful delivery through conventional formulations. Hence, efforts are required to develop nanoformulations of vanillic acid to overcome the associated challenges.
