  • Publication number: 20250017840
    Abstract: A novel senotherapy peptide and a method for senotherapy are disclosed. The method for sentherapy includes administering an effective amount thereof to a subject in need thereof. The novel senotherapy peptide suppresses the interaction between p53 and FOXO4 in the nucleus due to a better binding force with p53 than FOXO4, thereby allowing p53 to be released out of the nucleus and move to mitochondria to induce apoptosis of senescent cells and selectively induce the apoptosis of senescent cells in the skin cells.

  • Publication number: 20230167241
    Abstract: A method for producing polyether ketone ketone at a high yield is disclosed. According to the method, a catalyst injection rate is controlled during production to suppress scale formation, whereby the yield can be improved. A polyether ketone ketone produced by the method is disclosed. The method makes it possible to maintain an intrinsic viscosity (IV) of the polymer without a significant change and adjust a particle size of polyether ketone ketone by preventing an aggregation between resin particles, thereby suppressing scale formation.
