Abstract: The present disclosure relates to a cancer cell-specific complex for targeting cancer. The complex for targeting cancer according to the present disclosure includes EGF, but is affected more by lysosomal activity rather than the EGFR signaling pathway, and thus can overcome the shortcomings of the existing EGF therapy-based diagnostic and therapeutic compositions and provide successfully personalized and improved effects of treating, preventing and alleviating cancer.
A diagnostic composition according to the present disclosure enables the prediction of the anticancer performance of a therapeutic composition of the present disclosure in a subject, and thus enables anticancer treatment to be designed stably.-

Abstract: Disclosed is a prodrug for preventing or treating cancer. The prodrug is mediated by albumin present in the blood to achieve high cancer selectivity for cancer and high stability. Also disclosed is a pharmaceutical composition for preventing or treating cancer including the prodrug. The anticancer prodrug and the pharmaceutical composition form a conjugate with albumin even without using a carrier or delivery vector when injected in vivo. Therefore, the anticancer prodrug and the pharmaceutical composition are effective in preventing or treating cancer, have increased in vivo half-lives, and can accumulate in cancer with increased efficiency to significantly alleviate the side effects of the anticancer drug.

Abstract: Disclosed is an optimal peptide-liposome complex capable of multivalent crosslinking with PD-L1 on the cell surface to induce degradation of PD-L1. The peptide-liposome complex effectively blocks PD-L1, an immune checkpoint on the surface of cancer cells, and prevents the recycling of PD-L1 by intracellular metabolism to induce complete degradation of PD-L1 in cancer cells, achieving an increased therapeutic effect on cancer.

Abstract: A fusion protein-siRNA complex according to the present disclosure binds specifically to cancer cells, is taken up effectively by the cells, and exhibits anticancer activity as it is degraded by lysosomes. The fusion protein-siRNA complex provides maximized anticancer activity so that the cancer cells can be removed by autoimmunity, by inhibiting the immunity of the cancer cells and enhancing phagocytosis by macrophages.

Abstract: Disclosed is a drug conjugate as a prodrug that is degraded by cathepsin B specifically expressed in tumor tissues to release doxorubicin. The drug conjugate can form self-assembled nanoparticles. In addition, the drug conjugate specifically responds to and is activated in tumor cells. Therefore, the use of the drug conjugate eliminates the incidence of side effects (for example, cell damage and apoptosis) during the course of cancer prevention or treatment.

Abstract: The present disclosure relates to a glycopeptide targeting cancer cells and a contrast agent kit containing the same. The glycopeptide is one wherein an azide reporting monosaccharide is bound to a substrate peptide. As the substrate peptide is specifically cleaved by cathepsin B in cancer cells, an azide reporting monosaccharide is expressed onto the cell surface via metabolic glycoengineering, thereby providing a target for action as a contrast agent. Accordingly, because the azide is exposed to the cell surface only by cathepsin B, as it is specifically expressed in cancer cells, in particular in metastatic cancer cells, while it is limitedly expressed in normal cells and is hardly excreted out the cells, the cancer cells can be selectively imaged by an azide-specific contrast agent.
