[The epidermal barrier].
Abdayem R, Haftek M. Abdayem R, et al. Ann Dermatol Venereol. 2018 Apr;145(4):293-301. doi: 10.1016/j.annder.2017.12.001. Epub 2018 Apr 4. Ann Dermatol Venereol. 2018. PMID: 29625778 French.
To protect against harmful ultraviolet radiation, the epidermis has absorption factors such as melanin, produced by melanocytes, and urocanic acid, which is a degradation product of filaggrin. The epidermal immune defence system comprises an innate component, which …

High pressure Raman investigation on trans-urocanic acid.
Kumar N, Murli C, Varma M, Poswal HK, Thomas S, Kshirsagar RJ. Kumar N, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2022 Feb 5;266:120438. doi: 10.1016/j.saa.2021.120438. Epub 2021 Sep 27. Spectrochim Acta A Mol Biomol Spectrosc. 2022. PMID: 34627016
Trans-urocanic acid (t-UCA) is an important epidermal UV protector predominantly found in human skin. Exposure of UV radiation triggers photoisomerization of t-UCA into its other conformer, cis-urocanic acid (cis-UCA), which has been shown to be a medi …

Isolation of S-[2-carboxy-1-(1H-imidazol-4-yl)ethyl]cysteine from human urine.
Kinuta M, Ubuka T, Yao K, Futani S, Fujiwara M, Kurozumi Y. Kinuta M, et al. Biochem J. 1992 Apr 1;283 ( Pt 1)(Pt 1):39-40. doi: 10.1042/bj2830039. Biochem J. 1992. PMID: 1567378 Free PMC article.
Compound (I) was synthesized in 80% yield by incubation of a reaction mixture containing trans-urocanic acid and 3-fold excess of cysteine at 70-75 degrees C. From these results we suggest that natural thiol compounds such as cysteine and GSH participate in the meta …
