  • Series of resveratrol-derivative fluorescently labeled molecules and synthesis method thereof
    Patent number: 10125119
    Abstract: The invention discloses a series of resveratrol-derivative fluorescently labeled molecules and a synthesis method thereof. The fluorescently labeled molecules has a molecular formula as shown in formula (I). The synthesis method includes the steps of adding a certain amount of resveratrol derivative and solvent in a reaction vessel, adding a fluorescent marker as shown in formula (III) and a certain amount of alkali, reacting at 20° C.-60° C. for 2-10 hours, and after the reaction is completed, spin-drying the reaction solvent and performing post-processing to obtain the products.
    Type: Grant
