The invention belongs to the technical field of
drug delivery, and particularly relates to a mannosylation
hybrid membrane encapsulated Cu / Zn-MOF
drug delivery system and a preparation method and application thereof.The
drug delivery system comprises mannosylation
hybrid membrane encapsulated H-151-loaded Cu / Zn-MOF, the
hybrid membrane is prepared by fusing lipidosome and a
macrophage cell membrane, and the lipidosome and the
macrophage cell membrane are combined to form the mannosylation hybrid membrane loaded H-151-loaded Cu / Zn-MOF
drug delivery system. The preparation method comprises the following steps: dissolving H-151 in
dimethyl sulfoxide, dropwise adding a Cu / Zn-MOF
methanol suspension, stirring, centrifuging, and washing to obtain H-151-loaded Cu / Zn-MOF; mixing the macrophage membrane with lipidosome, performing ultrasonic treatment, and extruding through a
polycarbonate membrane to obtain a hybrid membrane; preparing lipidosome by adopting DSPE-PEG-Man, and fusing the lipidosome with a macrophage membrane to obtain a mannosylation hybrid membrane; the H-151-loaded Cu / Zn-MOF is mixed with the mannosylation hybrid membrane, incubation and
centrifugation are performed, and the H-151-loaded Cu / Zn-MOF encapsulated by the mannosylation hybrid membrane is obtained. The mannosylation hybrid membrane encapsulated Cu / Zn-MOF
drug delivery system has the functions of accurate delivery, intelligent release,
oxidation resistance and
inflammation resistance, and accurate and efficient treatment of inflammatory diseases is achieved.
