Abstract: One aspect of the disclosure relates to a cargo delivery system comprising an autophagy targeting ligand and a target-binding ligand. In one aspect of the disclosure, by comprising an autophagy targeting ligand, cargo, which is a target-binding ligand that specifically binds to a target, is delivered to the p62 protein and autophagy is activated, so that depending on the type of target-binding ligand used, a target to be degraded can be selectively and directly removed. Accordingly, the cargo delivery system according to an aspect of the disclosure may be used in pharmaceutical compositions or food compositions for preventing, alimerating, and treating various diseases.

Abstract: A composition has effects for promoting endoplasmic reticulum (ER)-phagy, a composition for maintaining ER homeostasis or reducing ER stress, and a pharmaceutical composition for preventing and/or treating ER-stress-related diseases. The composition contains a p62 ligand compound as an active ingredient. The p62 ligand compound can modulate p62 to interact with a receptor associated with autophagic degradation of ER component, modulate oligomerization and/or aggregation of the receptor, modulate formation of autophagosomes, and the like. Thus, uses of p62 ligand compound in inducing ER-autophagy are provided.

Abstract: The present invention relates to a composition for preventing, alleviating or treating inflammatory diseases, comprising, as an active ingredient, an acylhydrazone derivative compound, a stereoisomer thereof or a pharmaceutically acceptable salt thereof. an acylhydrazone derivative compound, a stereoisomer thereof or a pharmaceutically acceptable salt thereof, of the present invention, effectively inhibits inflammatory cytokines and inflammatory signaling pathways, thereby effectively alleviating symptoms of inflammatory diseases such as dermatitis. Therefore, the composition according to the present invention may be effectively used for the prevention, alleviation or treatment of inflammatory diseases.

Abstract: The present invention relates to a novel p62 ligand compound, a stereoisomer, hydrate, solvate or prodrug thereof, and a pharmaceutical or food composition for preventing or treating proteinopathies comprising the same as an active ingredient. The p62 ligand compound according to the present invention can be usefully used as a pharmaceutical composition for the prevention, amelioration or treatment of various proteinopathies by activating autophagy in cells and thus selectively eliminating in vivo proteins, organelles and aggregates.

Abstract: The present invention relates to a novel AUTOTAC chimeric compound in which a new p62 ligand and a target-binding ligand are connected by a linker, a stereoisomer, hydrate, solvate or prodrug thereof, and a pharmaceutical or food composition for the prevention or treatment of diseases by degrading the target protein including the same as an active ingredient. They can target specific proteins to adjust their concentrations, and can also deliver drugs and other small molecule compounds to lysosomes. The AUTOTAC chimeric compound according to the present invention can be usefully used as a pharmaceutical composition for the prevention, amelioration or treatment of various diseases by selectively eliminating specific proteins.

Abstract: The present invention relates to a novel p62 ligand compound, a stereoisomer, hydrate, solvate or prodrug thereof, and a pharmaceutical or food composition for preventing or treating misfolded protein diseases comprising the same as an active ingredient. The p62 ligand compound according to the present invention can be usefully used as a pharmaceutical composition for the prevention, amelioration or treatment of various proteinopathies by activating selective autophagy in cells and thus selectively eliminating in vivo proteins, organelles and aggregates.

Abstract: The present invention relates to a composition for preventing, alleviating or treating inflammatory diseases, comprising, as an active ingredient, an acylhydrazone derivative compound, a stereoisomer thereof or a pharmaceutically acceptable salt thereof. an acylhydrazone derivative compound, a stereoisomer thereof or a pharmaceutically acceptable salt thereof, of the present invention, effectively inhibits inflammatory cytokines and inflammatory signaling pathways, thereby effectively alleviating symptoms of inflammatory diseases such as dermatitis. Therefore, the composition according to the present invention may be effectively used for the prevention, alleviation or treatment of inflammatory diseases.
