N-Hydroxycinnamoyl amides of fluorinated amino acids: Synthesis, anti-tyrosinase and DPPH scavenging activities
Autor: Xinghua Guo, Maya Chochkova, Ernst Lankmayr, Boyka Stoykova, Galya Ivanova, Tsenka S. Milkova, Andreas Ranz
Publikováno v: Journal of Fluorine Chemistry. 156:203-208
A series of N -hydroxycinnamoyl amides of fluorinated amino acids were synthesized. Their antioxidant activity was determined using the rapid DPPH test and the activity was compared to that of non-fluorinated analogs and standard antioxidants. Result
