Oxidation of caffeic acid and related hydroxycinnamic acids
Journal of Electroanalytical Chemistry, 1996Abstract Oxidation of caffeic acid (3,4-dihydroxycinnamic acid) 1H3 has been studied by electrochemical methods and by pulse radiolysis in aqueous and organic solvents. The results have been compared with the behaviour of 4-coumaric acid 2H2 and ferulic acid 3H2.

Caffeic acid phenethyl ester (CAPE) is a bioactive polyphenolic compound obtained from propolis extract. Although it has a broad therapeutic potential, the bioavailability of CAPE is limited, due to reduced solubility and poor plasmatic stability. Efforts to reduce these pharmacokinetic drawbacks resulted in the synthesis of caffeic acid phenethyl ...

Reaction of caffeic acid derivatives with acidic nitrite
Tetrahedron Letters, 2001Abstract Caffeic derivatives were reacted with acidic nitrite at controlled pH in order to mimic the gastric juice conditions. At pH 2, whereas caffeic acid reacts exclusively on the side chain, its esters are readily nitrated. Under more acidic conditions (pH 1), caffeic acid methyl ester undergoes a dimerisation into a norlignan derivative.

Conformational study of caffeic acid derivatives
Journal of Molecular Structure: THEOCHEM, 2010Abstract The conformational analysis of six tripodal caffeic acid derivatives is obtained through semiempirical (AM1 and PM3) and Density Functional Theory (B3LYP/DZVP2, in this case) calculations. It was found that structures with small tripodal sides ( n = 1) are mainly stabilized by π electron delocalization.

Antitumor effect of propolis : a comparison with caffeic acid and caffeic acid phenethyl ester
1999The antitumor effect of a water soluble derivative of propolis (WSDP) caffeic acid (CA) and caffeic acid phenethyl ester (CAPE), components of natural propolis, were investigated. The oral administration of these compounds (50 mg/kg or 150 mg/kg) given before or after tumor cell inoculation supressed tumor growth of a weakly immunogeneic mammary ...
