Application of diatomic iron-iron site nano-enzyme in preparation of targeted osteoarthritis treatment medicine by relieving oxidative stress and cartilage degeneration
PendingCN121846307APromote productionincrease distanceHeavy metal active ingredientsAntipyreticDimerPorous carbon
The invention relates to a diatomic iron-iron site nano-enzyme constructed by relieving oxidative stress and cartilage degeneration and used for targeted osteoarthritis treatment. According to the invention, a nitrogen-doped porous carbon anchored diatomic iron nano enzyme catalyst (Fe2-NCs) with Fe-Fe dimer coordination is developed by using a'subject-object 'strategy. The Fe2-NCs protect cartilage cells from oxidative stress induced apoptosis by modulating ROS and active nitrogen species (RNS) and promoting O2 release. In addition, Fe2-NCs restores mitochondrial function by inhibiting NOX4 expression, improving ATP production, and normalizing COXIV levels. In an in-vivo OA model, the Fe2-NCs can reduce the expression of a pro-inflammatory medium COX-2 through an NF-kappa B signal channel, inhibit the up-regulation of MMP-13 and delay the degradation of type II collagen. The invention provides a new theoretical framework and methodological approach for the treatment of osteoarthritis, and has important clinical and scientific significance.
