  • Patent number: 11969397
    Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

  • Patent number: 10232350
    Abstract: A photocatalytic functional film has a structure of a substrate, a barrier layer and a photocatalytic layer stacked one on another. The barrier layer is a SiO2 film, the photocatalyst layer comprises an amorphous TiO2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a silicate precursor to obtain a SiO2 sol by dehydration and de-alcoholization reaction; applying and drying the SiO2 sol on a substrate to form a barrier layer; adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO2 amorphous sol by dehydration and de-alcoholization reaction; and applying and drying a composition formed by mixing particles of visible light responsive photocatalyst material with the TiO2 amorphous sol on the barrier layer, to form a photocatalyst layer.
