  • Chimeric antigen receptor that binds HLA-DR and CAR-T cell
    Patent number: 11951130
    Abstract: The present invention relates to an antigen-binding molecule comprising a heavy chain variable region comprising a heavy-chain complementarity-determining region 1 (HCDR1) comprising an amino acid sequence represented by Sequence No. 1, an HCDR2 comprising an amino acid sequence represented by Sequence No. 2, and an HCDR3 comprising an amino acid sequence represented by Sequence No. 3; a light-chain variable region comprising a light-chain complementarity-determining region 1 (LCDR1) comprising an amino acid sequence represented by Sequence No. 4, an LCDR2 comprising an amino acid sequence represented by Sequence No. 5, and an LCDR3 comprising an amino acid sequence represented by Sequence No. 6; wherein the antigen-binding molecule is a T cell receptor (TCR); and to a cell line expressing the same.

  • Composition for skin whitening comprising ?-mangostin as effective ingredient
    Patent number: 11882858
    Abstract: A skin whitening composition includes ?-mangostin or a cosmetically acceptable salt thereof as an effective ingredient. ?-Mangostin represented by Chemical Formula 1 suppresses the expression of tyrosinase and TRP-1 (tyrosinase-related protein-1) and induces autophagy of a melasosome. As such, it was confirmed that the ?-mangostin not only suppresses melanin production but also exhibits the effect of removing previously formed melanin. Accordingly, the ?-mangostin can be advantageously used as a functional material for skin whitening and skin lightening.

  • Composition for skin whitening comprising amorphigeni as effective ingredient
    Patent number: 10500146
    Abstract: A skin whitening composition includes amorphigeni or a salt thereof as an effective ingredient. Amorphigeni suppresses the expression of tyrosinase and induces autophagy on melanosomes. As such, it was confirmed that amorphigeni not only suppresses melanin production but also exhibits the effect of removing melanin previously produced by ?-MSH (melanocyte-stimulating hormone). Accordingly, amorphigeni can be advantageously used as a functional material for skin whitening and skin lightening.
