Bioactivity | Robinetin (3,3',4',5',7-Pentahydroxyflavone), a naturally occurring flavonoid with remarkable ‘two color’ intrinsic fluorescence properties, has antifungal, antiviral, antibacterial, antimutagenesis, and antioxidant activity. Robinetin also can inhibit lipid peroxidation and protein glycosylation[1][2][3][4][5]. |
Invitro | Robinetin (0.1-10 μM; 1 h) inhibits HIV integrase cleavage and integration in a dose-dependent manner[1].Robinetin inhibits the DNA synthesis in Proteus vulgaris, and the RNA synthesis in S. aureus[2].Robinetin (100-200 or 25 μM; 1 or 72 h) inhibits egg yolk phosphatidylcholine (EYPC) membrane lipid peroxidation and hemoglobin A (HbA) glycosylation with high efficiency[3].Robinetin exhibits photo-induced excited-state intramolecular proton transfer resulting in ‘two color’ (in ‘blue-violet’ and ‘yellow-green’ regions) fluorescence characteristic of flavonols, the relative contributions between the two colors being strongly modulated by the local environment of the fluorophore[3]. |
