The invention discloses a preparation method and application of
sesamin targeted carrying nanoparticles, and the preparation method comprises the following steps: reacting ketal
thiol TK, 2-succinimido-1, 1, 3, 3-
tetramethylurea tetrafluoroborate, N, N-diisopropylethylamine and iramitide SS-31
peptide to prepare an SS31
peptide-TK compound, then reacting with
chitosan, and simultaneously preparing a
sodium alginate-
lactobionic acid compound, so as to obtain the
sesamin targeted carrying nanoparticles. Finally, mixing the two solutions to obtain a covalent complex; the method comprises the following steps: baking pork slices, extracting with
ethanol, filtering, carrying out rotary
evaporation, extracting, dialyzing and purifying, and freeze-
drying; and mixing the products of the first two steps, dissolving in
ethanol, adding
sesamin, and carrying out electrostatic self-
assembly and
freeze drying to obtain the visual sesamin
targeted nanoparticles. According to the invention, specific positioning of liver mitochondria, ROS stimulation response intelligent
drug release and real-time
visualization of food-borne
fluorescence labeling are realized, and the application prospect in prevention and treatment of liver diseases is wide.
