| abstract |
The present invention relates to a drug carrier having a cell targeting and drug release function, and provides a drug carrier comprising a site binding to a specific cell surface, a site having a drug release function, and a target drug. The drug carrier of the present invention can be conveniently prepared by a substance that binds to a specific cell surface and a substance that induces endoendosome structural changes to increase drug release, and targets specific cells to be partitioned into endosomes and at the same time the drug in the endosome By increasing the release of, specific cells can be specifically killed, which can be usefully used in the pharmaceutical field. |
