US Patent 11104704 Peptide having cytoprotective effect against environmental pollutant and use thereof

Provided are a peptide with a cytoprotective effect against environmental pollutants and a use thereof. The peptide consisting of an amino acid sequence of SEQ ID NO: 1, 2, or 3 directly binds to 2,3,7,8-tetrachlorodibenzo-p-dioxin (hereinafter, referred to as TCDD), known as being the most toxic among the class of dioxins, to prevent dermal penetration and the activation mechanism of AhR by TCDD and polycyclic aromatic hydrocarbons contained in fine dust. Such a direct cytoprotective effect against environmental pollutants is distinguished from preexisting methods that are configured to indirectly block opportunities to contact these materials or to reduce toxicity through barrier reinforcement.
