The invention relates to the technical field of drugs for acute organ injury, and particularly discloses
idebenone-modified
platelet membrane-coated mitochondria as well as a preparation method and application thereof, aiming at the problems of low
drug delivery efficiency, insufficient targeting and the like of ROS (
reactive oxygen species) removal drugs for acute organ injury at present. The in-vitro mitochondria-modified
platelet membrane comprises in-vitro mitochondria and an
idebenone-modified
platelet membrane
coating the in-vitro mitochondria, the preparation method comprises the following steps: S1, extracting a platelet membrane; s2, extracting mitochondria; s3, mixing the platelet membrane with mitochondria, and centrifuging for multiple times to obtain platelet membrane coated mitochondria; and S4, incubating and combining the platelet membrane-coated mitochondria with
idebenone, carrying out centrifugal washing for multiple times, adding a
lysis solution, and carrying out
lysis, ultrasonication and separation to obtain the idebenone-modified platelet membrane-coated mitochondria. A platelet membrane is modified by idebenone, a
mitochondrial targeting delivery system is constructed and directly acts on
active oxygen in cells, and the pertinence and efficiency of therapeutic drugs are improved.
