Fisetin from Dietary Supplement to a Drug Candidate: An Assessment of Potential - A Review.

Abstract

Fisetin is a bioactive compound found in numerous fruits and vegetables, including strawberries, apples, grapes, persimmon, cucumber, onion, etc. The compound is also wellknown for its neurotrophic, anti-inflammatory, anti-carcinogenic, anti-diabetic, and other healthpromoting properties. Although there is increasing agreement that it has therapeutic properties, its poor water solubility, high lipophilicity, and lower oral bioavailability make it difficult to use clinically. Extensive research has attempted to overcome these restrictions by developing novel, superior delivery systems. Considering the diverse potential, this review is the first to summarise the available data on Fisetin to collate the information related to analytical methods, pharmacological action, their mechanisms, regulatory aspects, and toxicity profile. It also covers the marketed products, their related clinical trials, and patent updates of the moiety. In addition, an endeavor has been attempted to discuss and assess the various drug delivery systems employed to increase the biological attributes of Fisetin. The presented manuscript is the first to present a compendium of up-to-date literature on all of the domains considered necessary for this type of natural molecule to carve down its path from being a mere dietary supplement to a promising therapeutic drug candidate. The manuscript will definitely benefit the researchers working on natural and bioactive compounds, industrial scientists, and the general population interested in Fesitin as a dietary supplement.
