A Comprehensive Review of Robinetin: Distribution, Biological Activity and Pharmacokinetic Parameters

Robinetin, a naturally occurring polyhydroxylated flavonol, has gained attention due to its broad spectrum of biological activities and potential therapeutic applications. This review presents a comprehensive summary of the current knowledge concerning the natural occurrence, extraction, spectroscopic characterization, and pharmacological properties of robinetin. Ethnobotanical evidence highlights its presence in various medicinal plants, particularly within the Fabaceae family, where it contributes to traditional treatments of infections, inflammation, and metabolic disorders. Robinetin exhibits diverse bioactivities, including antiviral, antibacterial, antiparasitic, antioxidant, anti-mutagenic, and enzyme-inhibitory effects. Notably, it inhibits HIV-1 integrase and acetylcholinesterase and demonstrates moderate antiproliferative activity in cancer cell lines. Despite limited water solubility, its redox behavior and metal-chelating capabilities support its antioxidant potential. Recent in vivo studies indicate its hepatoprotective and metabolic regulatory effects. Additionally, computational models reveal promising interactions with molecular targets such as CDK1. Collectively, these findings underscore the multifaceted therapeutic potential of robinetin and advocate for further pharmacokinetic and clinical investigations to validate its efficacy as a lead compound for the development of phytochemically derived pharmaceuticals.
