In 2022,Yuan, Zhenbo; Lu, Liushen; Liu, Meiling; Liu, Xuanzhong; Liu, Changmei; Yin, Dejing; Zhang, Yan; Rao, Yijian published an article in Green Chemistry. The title of the article was 《Natural product cercosporin as a bioinspired photocatalyst for the synthesis of peptides containing kynurenine via an energy transfer mechanism》.Reference of H-Trp-OMe.HCl The author mentioned the following in the article:
Cercosporin-catalyzed photo-mediated oxidation for the rapid and efficient synthesis of kynurenine (Kyn) derivatives as well as Kyn-containing peptides under mild conditions was developed, exhibiting great functional group tolerance and broad substrate scope to produce various nonproteinogenic peptides. This environmentally friendly process utilized the natural product cercosporin (CP) as a metal-free photocatalyst, visible light as a sustainable energy source, and oxygen as a green oxidant. Moreover, the synthetic utility of this photooxidation reaction was exemplified by the gram-scale synthesis employing crude CP conveniently obtained from the fermentation broth of Cercospora, and the successive transformation to kynurenine. Finally, preliminary mechanistic studies revealed that an energy transfer pathway was involved in the reaction. In addition to this study using H-Trp-OMe.HCl, there are many other studies that have used H-Trp-OMe.HCl(cas: 7524-52-9Reference of H-Trp-OMe.HCl) was used in this study.
H-Trp-OMe.HCl(cas:7524-52-9) is one of amino acid derivatives. Amino acid derivatives represent an important category of skin penetration promoters. These compounds possess hydrophobic chains attached to an amino acid headgroup via a biodegradable ester bond. Due to the amphiphilic nature of these derivatives, it is possible for them to enter into the SC lipid barrier and significantly disorganize skin membrane lipids.Reference of H-Trp-OMe.HCl
