In 2019,Youji Huaxue included an article by Wang, Zhen; Zhang, Ling; Zhang, Fugeng; Wang, Bin. Application of 7524-52-9. The article was titled 《Synthesis of β-carbolines through tetra-n-butylammonium bromide mediated cycloaromatization reaction of N-methylaniline with tryptophan derivatives》. The information in the text is summarized as follows:
A mild and efficient nBu4NBr-mediated oxidative cycloaromatization to prepare β-carbolines from readily available tryptophans and N-methylaniline is described. The present metal free protocol is complementary to the existing methods for the synthesis of aromatic β-carbolines. In the experiment, the researchers used H-Trp-OMe.HCl(cas: 7524-52-9Application of 7524-52-9)
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.Application of 7524-52-9
