  Anti-tyrosinase, antioxidant and antimicrobial activities of hydroxycinnamoylamides

  摘要：

  Synthetic hydroxycinnamoylamides of amino acids (precursors of aromatic amines) were studied for their antioxidant activity in vitro by two antioxidant assay systems, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and inhibition of lipid peroxidation (LPO). Furthermore, these compounds were tested and compared with their corresponding cinnamoylamides of aromatic amines for their inhibitory activity using mushroom tyrosinase. In addition, five hydroxycinnamoyl amino acid amides were investigated for their antimicrobial effect. Structure-activity relationships analysis disclosed that the presence of catechol rest at amino acid or at benzene moieties of substituted cinnamic acid amides significantly scavenged DPPH radical and inhibited LPO. The results obtained by LPO clearly expressed the positive influence of indole moiety on the activity. Moreover, the existence of p-hydroxy substituted cinnamic acid moiety leads to better tyrosinase inhibition. Amongst the tested compounds, amides of p-coumaroyldopamine or tyramine and their corresponding amino acid precursors are the most potent tyrosinase inhibitors.
