    3-CPs

    3-Carbethoxypsoralen; 3-Ethoxycarbonylpsoralen

    		 Bacterial Infection
    3-CPs is a monofunctional furanocoumarin and a photoprotective agent targeting Staphylococcus aureus DNA, possessesing anti-UVB lethal activity. 3-CPs competitively intercalates into DNA, forming exclusively 4',5'-furan-side mono-adducts upon UVB irradiation, and irreversibly inhibits the formation of cyclobutane pyrimidine dimers. 3-CPs prevents UVB-induced DNA damage by preferentially binding to strong (AT)n sites within the DNA, without inducing lethal interstrand DNA cross-links; the limited number of mono-adducts it induces can be efficiently repaired by bacteria. 3-CPs holds potential for use in the development of photoprotective formulations for skin diseases, as well as in studies investigating bacterial DNA photodamage repair mechanisms and the optimization of photochemotherapy safety .

    Sucrose dilaurate

    		Autophagy Others
    Sucrose dilaurate acts as an emulsifier, dispersant and stabilizer. Sucrose dilaurate reduces the release of HMGB1 from UVB-irradiated keratinocytes. Sucrose dilaurate inhibits melanogenesis and decreases bilirubin levels. Sucrose dilaurate induces autophagy in human epidermal keratinocytes, thereby reducing carboxymethyl lysine (CML) levels. Sucrose dilaurate reduces the secretion of insulin-like growth factor-binding protein 3 (IGFBP3) and nerve growth factor (NGF) by senescent keratinocytes. Sucrose dilaurate is investigated as an emulsifier, dispersant or stabilizer in the cosmetics, food and pharmaceutical industries .
