体外研究 | Robinetin (0.1-10 μM; 1 h) inhibits HIV integrase cleavage and integration in a dose-dependent manner. Robinetin inhibits the DNA synthesis in Proteus vulgaris , and the RNA synthesis in S. aureus . 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. 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. |
