Fmoc-POAC: [(9-fluorenylmethyloxycarbonyl)-2,2,5,5-tetramethylpyrrolidine-N-oxyl-3-amino-4-carboxylic acid]: A novel protected spin labeled beta-amino acid for peptide and protein chemistry
(Pharmaceutical Soc Japan, 2001-08-01)
The stable free radical 2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino-4-carboxylic acid (TOAC) is the only spin labeled amino acid that has been used to date to successfully label peptide sequences for structural studies. ...

Comparative study of the cathodic cleavage of N-tosyl- and N-nosyl-protected amino acids
(Elsevier B.V., 1993-12-15)
The electrochemical behaviour of alanine and phenylalanine protected by the toluenesulphonyl (tosyl) and nitrobenzesulphonyl (nosyl) groups was examined in dimethyl formamide. The N-tosyl-protected amino acids are reduced ...
Dual-protected amino acid derivatives as new antitubercular agents
(Wiley-Blackwell, 2018-08-01)
Tuberculosis is an infectious disease with high incidence and growing drug-resistant rates. In an attempt to develop new antitubercular agents, 35 compounds were synthesized, most of them bearing a carbamate and enantiopure ...
Comparative study of the cathodic cleavage of N-tosyl- and N-nosyl-protected amino acids

Sulfur‐containing amino acids that increase renal glutathione protect the kidney against papillary necrosis induced by 2‐bromoethylamine
(1990)
Papillary necrosis was observed in the kidneys of rats, 72 h after receiving a single injection of bromoethylamine (BEA). This effect was associated with renal glutathione (GSH) depletion 1 h after the administration of ...
Short communication: Mycosporine-like amino acids protect natamycin against photodegradation in milk exposed to fluorescent or light-emitting diode light
(2019-06-01)
Natamycin has been used as a natural antimicrobial in dairy products, but the poor light stability of natamycin can limit usefulness in food products. Mycosporine-like amino acids are strong UV absorbers and might be useful ...
Synthesis and evaluation of a chiral stationary phase based on quinine: Enantioresolution of dinitrophenyl derivatives of α-amino acids
(Elsevier Science, 2011-06)
The natural alkaloid quinine (QN) was immobilized on porous silica particles, and part of the material was subsequently endcapped with n-hexyl hydrocarbon chains. Two synthetic strategies for silanization of the support ...
