Abstract: A compound represented by chemical formula 1, a salt, a stereoisomer, a solvent or a hydrate thereof, an antibacterial composition including the compound, and uses thereof are disclosed. The antibacterial composition is suitable for inhibiting bacterial infections, preventing, alleviating or treating bacterial infectious disease, and for preventing, alleviating or treating inflammation caused by a bacterial infection. The compound specifically binds to p62 protein so as to activate p62, thereby increasing the activity of autophagy, which is inhibited by a bacterial infection, and thus has antibacterial activity against various bacteria, can inhibit bacterial infectivity and has the excellent effect of enabling prevention, alleviation or treatment of bacterial infectious disease and inflammation caused by an infection.

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 specification discloses a novel benzyloxy pyridine derivative compound represented by Chemical Formula 1, a salt thereof, a stereoisomer thereof, a hydrate thereof, or a solvate thereof, and novel uses thereof. The uses comprise the uses in the preparation of a composition for activating autophagy, a composition for activating p62 protein, a composition for inducing oligomerization of p62 protein, or a composition for ameliorating, preventing or treating a disease caused by misfolded protein.

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: Novel p62 ligand compounds, or a stereoisomer, a solvate, a hydrate, or a prodrug thereof are disclosed. The novel compounds, stereoisomer, solvate, hydrate, or prodrug activates selective autophagy in cells to selectively remove proteins, organelles, and coagulations in the body, and thus can be advantageously used as a pharmaceutical composition for preventing, ameliorating, or treating various proteinopathies. Compositions such as pharmaceutical composition or food compositions containing the novel p62 ligand compounds, stereoisomer, solvate, hydrate, or prodrug thereof as well as uses thereof are disclosed.

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.
