  • Patent number: 11925672
    Abstract: The present invention provides a functional peptide having excellent antioxidant activity, the peptide having excellent biocompatibility and significantly better antioxidant activity than conventional GSHs in order to overcome the limitation of the weak antioxidant activity of existing peptides. The peptide of the present invention can promote antioxidant activity or effectively repair biological tissue or cell damage caused by reactive oxygen species generated due to oxidative stress. Therefore, the peptide having such antioxidant activity effectively acts on cell damage caused by oxidative stress, and can thus be used to prevent and repair cell damage.

  • Publication number: 20050112185
    Abstract: The present invention relates to positively charged lipids prepared by linking salt forms of acidic amino acid with a variety of lengths of hydrocarbon chain, a process for preparing the lipids, and liposomes comprising the said positively charged lipids. Positively charged lipids of the invention can be practically applied for the preparation of liposomes for gene therapy, since they provide better characteristics than the conventional positively charged lipids in terms of gene delivery efficiency and biocompatibility.
