Abstract

Highlights: [•] Eight N-hydroxycinnamoylamides of fluorinated amino acids have been synthesized, among them five are new. [•] We evaluated their antioxidative activities by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging test. [•] Among the tested amides, N-sinapoyl-3-fluorotyrosine methyl ester (5) exhibited the highest radical-scavenging activity. [•] SA-Trp(6-F)-OMe (4) inhibited the most significantly the formation of dopachrome in anti-tyrosinase assay. [ABSTRACT FROM AUTHOR]
