  • Patent number: 11899025
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating neurodegenerative diseases comprising a COX2 acetylating agent as an active ingredient and, more particularly, to a pharmaceutical composition for preventing or treating neurodegenerative diseases comprising, as an active ingredient, a COX2 acetylating agent which exhibits an effect of inhibiting the deposition of amyloid-? in brain neurons, reducing excessive neuroinflammatory responses, and increasing the phagocytosis of amyloid-? in microglial cells. The pharmaceutical composition for preventing or treating neurodegenerative diseases comprising the COX2 acetylating agent as an active ingredient has the effects of alleviating neuroinflammation by promoting COX2 acetylation in neurons and secreting specialized pro-resolving mediators (SPMs) and thus, can be very useful in the development of a preventive or therapeutic agent for neurodegenerative diseases.
